An overpumping condition is indicated when there is a fluid pound more than one-quarter of the way down on the downstroke because of insufficient fluid in the well to charge or fill the downhole pump. Basic animations of some common downhole scenarios with regards to operating efficiency of sucker rod pumps. The Titen HD® rod coupler screw anchor is designed to be used in conjunction with a single- or multi-story continuous rod tie-down system. Example: 20-125-RHBC-10-4-2-2. In the early 1990s, an industry task group analyzed the stresses that react on a downhole rod pump. There are four common ways subsurface rod pumps are abused. The pump displacement is determined on the basis of the pumping speed, unit stroke length, and plunger diameter. ... Windshield to Cowl Rubber and the Hold Down Catches for when the windshield is lying down. – Dimock, J., 2002: The Panacea Pump Tool. This is a great option ... *NEW* Tie Rod End Set - MB. However, this also increases the load on the rod string and the peak torque for the pumping unit. the pumping speed used. Such problems was overcome by introducing the Top Hold-Down pump instead of bottom hold down. I think what you asked is what the difference between rod pump and tubing pump is. The bedrock of our business is a full automation and optimization portfolio of hardware, software, and services for downhole monitoring, wellsite productivity enhancement, and asset integrity management. 54th Annual Southwestern Petroleum Short Course, 172-174. A local mechanic told me to turn the engine to top dead center on cylinder 1. 2000. It is situated so the pump hangs below both the tubing perforations and the seating nipple. J Pet Technol 48 (4): 330-336. Basic animations of some common downhole scenarios with regards to operating efficiency of sucker rod pumps. • B - Stationary barrel, bottom anchor pump. pumps are thin-walled, stationary barrel, top anchor pumps recognized by API as a standard design.

Featuring a variety of lid stays, flap stays, soft-down lid supports, soft-down stays and lid hinges for soft-closing cabinets and chests from manufacturers such as Sugatsune and Hafele. This may be as simple as respacing the pump as the fluid level decreases in the well annuli or changing the stroke length for the pump downhole, or it may require pulling the pump and altering its design. size has been added back in the latest edition of the standard. The top bolt hole will align with the fuel pump push rod and will have a 3/8" x 3/4" bolt in it. • Most previous correlations disregarded the effect of dynamic leakage in the pump. may result in excessive leakage by the pump. 11AX. While downhole pumps and sucker rods are the chief components of a sucker-rod lift type artificial lift system, a number of other components are also used in the subsurface portion of the system. The pump calculations should be done for the worst-use case. 47 Pin End Plunger to Valve Rod 50 Bottom Cup Hold Down 54 Sucker Rod 55 Suck Rod, Sub, Box and Box 56 Sucker Rod, Sub, Pin and Box 58 Guide, Spiral Rod Guides 70 Rod, Box Type 71 Rod, Pin Type Hold Downs, Mechanical 78 Top Lock, API Type 79 Top Lock, Pacific Type Length Special Material Size Material / ID Condition Finding the Part Number: Slippage or leakage can be calculated using the following equation, adapted from the 1987 edition of the Petroleum Engineering Handbook.[5].

Q1[16]), most pump shops are not covered under these rigorous plans. It is situated so the pump hangs below both the tubing perforations and the seating nipple. Various material descriptions, their API identification symbol, surface condition, base core hardness, base material, and base-material minimum yield strength for plated barrels, are shown in Table A of Spec. This general equation is. SPE disclaims any and all liability for your use of such content. in length per 1,000 ft of increased well depth. These are classified by the type of barrel (standing or traveling) and where the pump is anchored (top or bottom). Available in both cup & mechanical hold down. These include tubing, tubing anchor-catchers, tubing rotators, sinker bars, rod centralizers, and paraffin scrapers. Shown here are a single-acting, spring-return model, top, and double-acting with double rod-end, bottom. − Rod (Insert) Pumps, 3-types: based on where the hold-down is located (top or bottom) & whether the barrel is Stationary or Traveling. Thus, it becomes critical to have the pump shop and its employees audited by qualified personnel to ensure that training, workmanship, safety, and environmental considerations are adequate. RHB Pumps are heavy wall barrel bottom hold-down type insert pumps. These rules are recommended for all steel sucker-rod strings. two hold down rods, two washers & two wing nuts. B., 2007: Sand-Pro Sucker Rod Pump for Fluid with Sand Production Conditions in Down-Hole Sucker Rod Pumps. 11AX was modified to add not only new sizes and types of pumps with new quality, inspection, and tolerance requirements, but also standardized, widely used pump-component materials. API Spec. to permit adequate spacing. It has a thin-walled barrel configuration for threads on either end of the heavy-walled barrel and is available for metal plungers only. Remove cable tie and push hold down plug up into rod, connect rod and lower rod line to about 400mm above existing packer in hole, pump hold down plug down and completely out of rod line. The second aspect of pump sizing, once the pump diameter is selected, is ensuring that the downhole pump is properly built. Stationary Barrel, Top Anchor This pump style has the holddown located at the top of the pump. Because the pump displacement is greater than the well capacity, the system will require some type of well control to prevent constant operation and overpumping of the well. polished stainless steel. Jr. and Thomas, S. 2000. The top hold down rod pump (where the pump is below the seating nipple) is more commonly used as it is resistant to sand sticking and is typically easier to remove from the well when removal is required. Paper 22 presented at the 2001 Southwestern Petroleum Short Course, Lubbock, Texas, 24–25 April. They provide improved stroke efficiency and longer rod-string life, which reduces failures and increases production. Non API pump design. API RP 11AR, Recommended Practices for Care and Use of Subsurface Pumps, fourth edition. This implies that pumps with fits larger than those selected on the basis of earlier predictions can be used without experiencing too high pump leakages. Top Seal The Don-Nan Top Seal prevents a stuck pump scenario caused by solids accumulation around the hold-down. Large-Volume Stroke-Through Pumps The FRP-rod manufacturer should have, or have access to, a sucker-rod-string design program that will estimate the increased plunger travel. two hold down rods, two washers & two wing nuts. New cables are recommended with each new top. The minimum plunger length recommended is normally 3 ft. Insert type pump, can be pulled with rod string. Properly setting a well controller will help reduce severe overpumping. ISO 9001, Intl. There are two aspects to consider when sizing the downhole pump for an installation. New cables are recommended with each new top. This anchor provides a fast and simple way to attach threaded rod to a concrete stem wall or thickened slab footing. The top hold-down anchor requires that fluid be discharged from the pump just above the seating nipple, which prevents sand or become stuck. ; N = pumping speed, spm; and D = diameter of the pump plunger, in. API RP 11AR[2] provides useful information on pump types, component and metallurgy selection, pump-setting-depth calculation, and pump assembly/teardown. This bolt needs to be removed and a longer 3/8" bolt installed in its place. How to improve Top-End RPM by adjusting hydraulic lifters for proper preload by Turning the rocker arm adjustment nut a lesser amount after reaching the zero-lash point. Indications of gas interference include low volumetric efficiency, while the fluid-level survey shows apparent, adequate pump submergence and a polish rod that is excessively hot to the touch. Sucker rod pumps are used primarily to draw oil from underground reservoirs. bore-rod-type pump with a 10-ft heavy-walled barrel, a 2-ft upper extension, a 2-ft lower extension, a 4-ft plunger, and a bottom-cup-type seating assembly that will be used in 2 3/8-in. Plunger lengths longer than 6 ft have not shown to be an advantageous, while specialty pumps may have a plunger shorter than 3 ft. Energy Resources Technology, Sept. 2004, 208-14. This is a down hole pump that is moving mineral oil. The complete pump designation of an API pump adds dimensional diameters and lengths to the letter designations. Chambliss, R. K. – Cox, J. C. – Lea, J. F.: “Plunger Slippage for Rod-Drawn Plunger Pumps.” J. The four bar linkage can be found on door dampers, on automobile engines, and on devices such as the lazy tong. The particulates may be caused by well conditions such as producing the fracturing sand back into the wellbore, very fine powder from the formation, iron sulfide scale from the downhole equipment because of inadequate corrosion inhibition, iron sulfide or other scales from the formation because of incompatible fluids, or from overpumping the well. Presented at the 2001/1/1/. Additionally, a pump with tighter fit tolerance/waste space, smaller pump diameter, increased stroke length, adequate downhole separation, and properly designed pump gas anchor should be considered along with properly placing the pump intake above or below the perforations as discussed in Sucker-rod lift. Abstract or Worlcat, Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro. Pump: − Tbg Pumps: largest bore pumps (dPgr just a 1/4” < ID of tbg). The types of fittings and their respective lengths depend on the type of pump being used. Comes with gasket as pictured. This was required to determine if there were recommended allowable loads that could be subjected to rod pumps of different types, sizes, and metallurgy. [1]. Thus, for a 5,000-ft-deep well, with a required 74-in. 1992. Review of New API Pump Setting Depth Recommendations. The compression ratio is the volume of the pump chamber at the start of the downstroke divided by the volume at the end of the stroke. The ends of the cables hold the top to the frame. The same seating nipple will accommodate either top or bottom hold-down pumps and the same hold-down assembly may be used for either top or bottom hold-downs by changing the end fittings.

It is recommended that the length of the plunger is increased 1 ft/1,000 ft of well depth, up to a 6-ft maximum length. 1964-1965 chevelle battery hold down. These pumps can also be modified for use as a stroke-through This type of pump is ideal for medium depth, sandy wells. Rod pumps also are called insert pumps because they are run (inserted) in the production tubing. permit axial movement of the pipe. two hold down rods, two washers & … An extensive series of theoretical and experimental investigations [6] [7][8] [9] on pump slippage resulted in the following main conclusions. The same seating nipple will accommodate either top or bottom hold-down pumps and the same hold-down assembly may be used for either top or bottom hold-downs by changing the end fittings. Available in both cup & mechanical hold down. [14]. (One approach is to take the launcher and your pump to the hardware store and ask for recommendations.) Some block assemblies are supplied from the factory with a 3/8" by 7/8" bolt with (2) thick washers under the head allowing the OEM bolt to be re-inserted without the washers to secure the rod in place. 29 List List Price $30.36 $ 30 . RWT Pumps are traveling thin wall barrel bottom hold down type insert pumps. The four common abuses follow: Because the recommended pump-displacement design is for the pump to have greater capacity than the well, an overpumping condition may occur if the well is not properly controlled. 11AX. Pads: Pads are installed under the top. Designed for maximum flow ; Designed for minimum turbulence. API Spec. • B - Stationary barrel, bottom anchor pump. A dynamometer survey, when combined with the precalculated well loads for the applicable design conditions, may indicate gas pound, gas lock, or inconsistency with the assumed conditions. ... Windshield to Cowl Rubber and the Hold Down Catches for when the windshield is lying down. for the plunger-barrel annuli have been considered; however, recent work done in both the laboratory and the field, has shown the benefit of increasing these tolerances to greater than 0.005 in. 29 List List Price $30.36 $ 30 . for wells up to 4,000 ft deep, then increases 6 in. This ratio is fixed by the manufacturer on the basis of the design of the rod pump's components and the fit of the plunger to the pump barrel. differential pressure across plunger, psi, Nominal tubing size (from 1.9- to 4.5-in. The API pump-bore sizes that are currently available range from 1 1/16 to 3 3/4 in. This pump has the hold-down on the bottom. API recognizes two main types of pumps: rod and tubing. Available in both cup & mechanical hold down. Once the pump reaches the desired pump depth, the hold down assembly seals with the tubing by seating into the hold down nipple. This length then should be used in the barrel-length determination. Once the pump has been placed in its seating location, the weight of the sucker rods on the pump pushes the rubber element outward until contact with the tubing wall is made. There is a wide range of plunger (or pump-bore) sizes standardized by the industry. Patterson, J. Paper 16 presented at the 2000 Southwestern Petroleum Short Course, Lubbock, Texas 12–13 April. Hein Jr., N.W. If sand is an issue, nonstandard accessories such as a top seal can be used to prevent a stuck pump. and Loudermilk, M.D. This has been modified in the latest revision to incorporate all approved sizes and barrel types along with separating the extensions into the top and bottom lengths, if required. This group developed the burst, collapse, and axial-loading equations to determine these limits and the associated maximum recommended setting depth for sucker-rod lift pumps, [4] published in API RP 11AR. Slippage in sucker-rod pumps takes two forms: static and dynamic slippage. New cables are recommended with each new top. Clamp the lifter in a vice with the topside facing upward. Place the push rod socket into the opening of the lifter valve body and push it up and down with an old push rod until oil seeps out of the lifter valve body hole. There are seven major components for downhole rod pumps: standing and traveling valves, plunger, barrel, seating assembly, pull tube or valve rod (for insert pump), and the fittings that hold the assembled pump together. ; μ = absolute viscosity of fluid, cp; and Lp = plunger length, in. 11AX. The Don-Nan Top Seal prevents a stuck pump scenario caused by solids accumulation around the hold-down. These Water Pumps are an exact reproduction with the smooth casting correct for the MB. Get started today creating your own convertible top! The excess of gas will then enter the pump, reducing its volumetric ... Separator 3: 2 – 3/8 Poor Boy Separator & Top Hold-down; The reached results with the selection of three separators are due to the dependence of Pdmax with a Install a TIE MAX 5/8” to 1/2” reducing coupler to the end of the TIE MAX threaded rod to be connected to the TIE MAX embed. Useful specialty pumps include the following: Additionally, there are special pump components, such as valve rods, valves, and tubing drains, that are sometimes beneficial in situations in which the capabilities of normal API pumps and components have been exceeded. This condition may be seen on the surface if the pound is very severe, but the best way to detect this is with the use of a dynamometer. The most common of these components and the final types of assembled pumps are covered by American Petroleum Institute (API) Specification 11AX. 54th Southwestern Petroleum Short Course, 2007, 45-59. of Corrosion Engineers (NACE), Houston. The importance of the compression ratio and associated waste space may prevent a new pump from being able to pump down a well. Tacking strips: Much of the installation involves tacking or stapling (there is no sewing involved.) Finally, if these normal solutions do not resolve the problem, then special pumps or specialty components may be considered. 21. Similar tables in Spec. ... NISSAN LEFT STEERING TIE ROD. 11AX. Proc. Worldcat, Parker, R. M. – Wacker, J. When fiber-reinforced plastic (FRP) rods are used, additional increased spacing may be required because of the increased "stretch" or elongation of the rod string under the load. There are seven major components for downhole rod pumps: standing and traveling valves, plunger, barrel, seating assembly, pull tube or valve rod (for insert pump), and the fittings that hold the assembled pump together. 2000. From there, your production fluids are effectively sealed from the reservoir fluid and pumping can begin. SPE-36163-MS. Patterson, J. et al. 2001. OD) - represented with 2 digits, Basic bore diameter (from 1.0625 to 3.75 in.) The shop, the knowledge of the design, selection of pump types, and associated component metallurgies become critical to long well life and a decreased failure frequency. 21. Shop now! The most common type cylinder is the single-rod end, in which the rod is nearly as long as the cylinder barrel. $28.95 $ 28. may cause producing problems, whereas loose clearances (greater than 0.008 in.) This section has all current high resolution images of Samson products ready for download. 1987. These slick hold down clamps securely hold your lines (brake, wiring, gas or cable) in place. Other indications of overpumping are if the pump volumetric efficiency is less than 70% or if a downhole fluid-level survey shows that the normal operating fluid level is at or very near the pump intake. Presented at the SPE Production Operations Symposium, Oklahoma City, Oklahoma, 21-23 March 1993. This pump has the hold-down at the top of the barrel, so the entire barrel and standing valve of the pump extend below the pump seating nipple. It is a nomenclature to classify API sucker rod pumps and tubing pumps according to their main characteristics. However, the surface stroke length may be considered an approximation of the maximum capacity for a given pumping situation. The slippage or leakage past a plunger on a closely fitted sucker-rod pump is an important factor in properly designing and operating a well. 11AX. The first is that the pump capacity should be related to the well capacity. This pump style has the holddown located at the top of the pump. Thus, this pump reduces the burst or collapse concerns of the thin-walled extension couplings and allows deeper producing depths to be attained. Patterson, J. et al. Other conditions that may cause this problem include if the pump-intake piping is plugged or not properly designed, if the pump has inadequate compression ratio, if the polished-rod clamp is not sufficiently tightened, and/or if the pump barrel is not properly sized. The standing valve and entire pump are above the hold-down inside the production tubing. Designed for maximum efficiency. Beam-Pumping Operations: Problem Solving and Technology Advancements. Washington, DC: API. This condition normally occurs because of inadequate pump spacing as the fluid level pumps down or because the pump has inadequate compression ratio/excessive waste space for the seating depth for the designed pumping parameters. New in original packaging. Tie Rod End for diesel and gas applications. Repro powdercoated hold down for group 24 battery. [1] The depth limitation and stresses on the downhole pump barrel and components should be considered when selecting the size, type, and metallurgy for a downhole pump. This made it much easier to install the new pump, as I no longer had to hold the pump lever down. This type of arrangement is great with sandy wells (especially shallow ones with a depth of less than 5,000 feet), due to the fluid’s whirling motion created during operations in the area at the pump’s top. Available in both cup & mechanical hold down. The recommended relationship of pump displacement to well capacity (WC), as discussed in Hein[12], is as follows: Thus, for a well that produces 100 BFPD, the various pumping parameters should be selected to provide a pump displacement of between 118 and 154 BFPD.
