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. API Spec. Downhole sucker-rod pumps are a key component of a sucker-rod lift type of artificial lift system. Insert type pump, can be pulled with rod string. For a completely eccentric position leakage rates 2.5 times greater than for concentric cases can be expected. A local mechanic told me to turn the engine to top dead center on cylinder 1. [17] Once the audit is performed and the checklist completed, the findings should be discussed with the appropriate pump-shop personnel and a time line developed detailing when changes to resolve any problem areas will be made. Similar tables in Spec. 11AX. 95 $30.50 $30.50. 2000. Plunger lengths longer than 6 ft have not shown to be an advantageous, while specialty pumps may have a plunger shorter than 3 ft. − Rod (Insert) Pumps, 3-types: based on where the hold-down is located (top or bottom) & whether the barrel is Stationary or Traveling. A … Can be built up to and including 3.50 bore size. Price is $325.00 . How to installl a new Gasket and "O"Rings on Cav Lucas Injector Pumps 45th Southwestern Petroleum Short Course, 1998, 180-91. The main variables to consider are as follows: Discussing these parameters with the pump manufacturer and local pump shop should help determine the proper pump to ensure acceptable pump life. 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. There are two aspects to consider when sizing the downhole pump for an installation. Available in both cup & mechanical hold down. It should be considered that as the pump diameter increases, the efficiency of the system increases. Beam-Pumping Operations: Problem Solving and Technology Advancements. Paper 16 presented at the 2000 Southwestern Petroleum Short Course, Lubbock, Texas 12–13 April. • Early formulas greatly overestimate the amount of liquid slippage. Insert pumps are installed by running in hole with the rod string. 11AX. Washington, DC: API. This is a great option ... *NEW* Tie Rod End Set - MB. It is important to know that the users of API pumps need to provide, along with the pump nomenclature, the following ordering information: barrel and plunger material, plunger clearance (or fit tolerance), and valve (ball and seat) and fittings material. Hold down cables: Cables are threaded through the side hems of the top and hold the top to the framework. shaft oil seals or damage will result. This can increase waste space in the pump, resulting in a decreased compression ratio. OD) - represented with 2 digits, Basic bore diameter (from 1.0625 to 3.75 in.) This pump has the hold-down on the bottom. 1987. 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: Tubing pumps are so named because the working barrel of this pump is coupled with the production-tubing string. for wells up to 4,000 ft deep, then increases 6 in. Between the three manufacturers, there are thousands of possible hydraulic power unit configurations, including electric driven, air driven, gas powered, battery driven and manual pumps. 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. 11AX. This is the "X-type" barrel. These pumps are suited for extremely abrasive or high-temperature wells. Comes with gasket as pictured. 36 hold-down pumps recognized by API as a standard design. – Watson, B. Because the pump barrel is threaded on the inside, there are fewer connections required, thereby reducing service costs. There is a wide range of plunger (or pump-bore) sizes standardized by the industry. Get it as soon as Mon ... Top Pick. This pump style has the holddown located at the top of the pump. This general equation is. The pump displacement is determined on the basis of the pumping speed, unit stroke length, and plunger diameter. BoatBuckle F14200 Gunwale/Deck Mount Retractable Rod Tie-Down. (Part No: C5NN3278A) $30.74 This BHD creates the possibility of sand & debris accumulating in the dead area between the pump and the tubing wall. New in original packaging. two hold down rods, two washers & two wing nuts. 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. Available in both cup & mechanical hold down. 2001. These problems may also be applicable to other downhole pumps, and thus, these related solutions probably are applicable to other artificial-lift techniques. Properly setting a well controller will help reduce severe overpumping. Hollow-Valve Rod Pumps These pumps improve the rigidity of valve rods and distribute pump discharge over a larger tubing area. Built with bottom or top hold downs Available with 3 cup seating assembly or mechanical hold down This pump has the hold-down on the bottom. 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. Jr. and Thomas, S. 2000. The FRP-rod manufacturer should have, or have access to, a sucker-rod-string design program that will estimate the increased plunger travel. 2000. and push the hold down plug up into rod until second cable tie is level with bottom of rod. Manufactured according to API 11AX specifications. [11] This work by McCafferty is further discussed in Hein[12] , which also presents different pump manufacturers' normal compression ratios for similar pump types. SPE-36163-MS. Patterson, J. et al. Abstract or Worlcat, Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro. There are four common ways subsurface rod pumps are abused. Non API pump design. However, the surface stroke length may be considered an approximation of the maximum capacity for a given pumping situation. of upper extension (if required)- single digit length, Length (in.) Presented at the SPE Production Operations Symposium, Oklahoma City, Oklahoma, 21-23 March 1993. It is comprised of seven parts, separated by dashes. Black Gold Pump & Supply, Inc. © All rights reserved. These include tubing, tubing anchor-catchers, tubing rotators, sinker bars, rod centralizers, and paraffin scrapers. $28.95 $ 28. Pumps with a shorter barrel than normally recommended, so that the plunger completely wipes solids free of the barrel and prevents sticking. Rod pumps are inserted inside the tubing and run as an assembled unit with the sucker rods. Mark the centerline on top of the sub-base and bottom of gear reducer and utilize this line for initial alignment. MR01-76, Metallic Materials for Sucker Rod Pumps for Hydrogen Sulfide Environments, Natl. – Dimock, J., 2002: The Panacea Pump Tool. More information. Worldcat, Parker, R. M. – Wacker, J. They provide improved stroke efficiency and longer rod-string life, which reduces failures and increases production. New cables are recommended with each new top. The high hydrostatic pressure present in the tubing string, acting on top of the plunger with the traveling valve closed, forces liquid to slip past the plunger into the pump chamber between the traveling and the standing valves. two hold down rods, two washers & … The bottom hold down rod pump (where the pump is … Assn. Stuck pumps In AGIBA application stuck pumps which existed only in the Bottom Hold-Down type. Great service, low prices, fast shipping. Left hand and right hand 1965 to 5/1967; Left hand only 6 of 1967 to 1975. These Water Pumps are an exact reproduction with the smooth casting correct for the MB. These rules are recommended for all steel sucker-rod strings. The pump manufacturer typically machines or obtains subcontract pump components for future assembly of the pump by a pump shop. U-20 NISSAN FACTORY OIL PUMP – This is Nissan part number 15010-25501 which is the standard U-20 oil pump. Available in both cup & mechanical hold down. The top hold-down anchor requires that fluid be discharged from the pump just above the seating nipple, which prevents sand or other solid material from accumulating and causing the pump to become stuck. Paper 22 presented at the 2001 Southwestern Petroleum Short Course, Lubbock, Texas, 24–25 April. [14]. Help with editing, Content of PetroWiki is intended for personal use only and to supplement, not replace, engineering judgment. Oops, there was an error sending your message. In the past, tighter fit tolerances (< 0.003 in.) Notice the standing valves turbulence when you have your pound much lower in the stroke. • B - Stationary barrel, bottom anchor pump. 11AX. The pump designation is part of API Spec 11AX and describes the main specifications of an API subsurface pump. Designed for maximum flow ; Designed for minimum turbulence. Washington, DC: API. While severely “tapping,” or “tagging,” the pump may be heard, felt, or seen, the smashed pump components obtained during a pump teardown will show the damage this condition causes. ; μ = absolute viscosity of fluid, cp; and Lp = plunger length, in. Patterson, J. et al. Available in both cup & mechanical hold down. Fluid Slippage in Down-Hole Rod-Drawn Oil Well Pumps. The top bolt hole will align with the fuel pump push rod and will have a 3/8" x 3/4" bolt in it. 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. The package comes with 12 clamps and... For All Cars and Trucks 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. The complete pump designation of an API pump adds dimensional diameters and lengths to the letter designations. • Most previous correlations disregarded the effect of dynamic leakage in the pump. diametrical clearance between plunger and barrel, in. of Corrosion Engineers (NACE), Houston. Rod Pump Shop Audits and Performance Requirements. Seating options include mechanical or cup types suitable for high temperatures and mechanical types to simplify well mainte- nance. These Water Pumps are an exact reproduction with the smooth casting correct for the MB. in which PD = pump displacement, BFPD; 0.1166 = a volumetric conversion; S = stroke length, in. A pump component hitting on the up- or downstroke is indicated by an instantaneous load change and can be shown with a load-capable dynamometer. Q1[16]), most pump shops are not covered under these rigorous plans. Seating options include mechanical or cup types suitable for high temperatures and mechanical types to simplify well maintenance. Pumps for sucker-rod lifted wells should be selected on the basis of numerous variables that are provided by the well, the operating conditions, and the life of the pump. when solids are a problem. Such problems was overcome by introducing the Top Hold-Down pump instead of bottom hold down. : “Progress Report #2 on “Fluid Slippage in Down-Hole Rod-Drawn Oil Well Pumps.” Proc. Find the Bimini Top Straps you need today. Thus, reasonable selection of these pumping parameters should be considered that results in extended run time. However, these items should be selected with care and used only after the best production effort has been thoroughly tested with standard components. 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. An extensive series of theoretical and experimental investigations [6] [7][8] [9] on pump slippage resulted in the following main conclusions. The types of pumps, sizes, and component materials that are included in the API standards are based on the best industry practices that meet widespread industry needs. permit axial movement of the pipe. Slide plates, such as PTFE, 25% glass filled or graphite, can be incorporated into the design to … A standard 12-ft barrel with 1-ft top and bottom extension couplings should be considered. to permit adequate spacing. 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. The minimum plunger length recommended is normally 3 ft. This spacing factor is normally a minimum of 24 in. However, the manufacturer of these components should create all parts to the same quality level required in API Spec. You must log in to edit PetroWiki. 2001. Finally, if these normal solutions do not resolve the problem, then special pumps or specialty components may be considered. 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. The second aspect of pump sizing, once the pump diameter is selected, is ensuring that the downhole pump is properly built. 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. API-RHA The RHA pump is a precision insert type API rod pump with a heavy wall barrel and either a cup or mechanical top hold-down. 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. The ends of the cables hold the top to the frame. For 4000, 4600, 4610. Once the previous factors are added together, the length-of-barrel calculation is normally increased to the next available whole-foot standard length for a pump according to API Spec. 29 List List Price $30.36 $ 30 . They 'build out' the top along the sides. To remove the pump, simply pull the rod string out of hole. in which Q = slippage or leakage loss, in.3/min; D = plunger diameter, in. 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. Tacking strips: Much of the installation involves tacking or stapling (there is no sewing involved.) This length then should be used in the barrel-length determination. The Don-Nan Top Seal prevents a stuck pump scenario caused by solids accumulation around the hold-down. 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. If you need hydraulic pumps then you need to talk to Dewald Fluid Power. These clamps are for a 1/2 inch single line.

Petroleum Engineering Handbook. 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. 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. 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. differential pressure across plunger, psi, Nominal tubing size (from 1.9- to 4.5-in. This made it much easier to install the new pump, as I no longer had to hold the pump lever down. The first is that the pump capacity should be related to the well capacity. I think what you asked is what the difference between rod pump and tubing pump is. 1992. Review of New API Pump Setting Depth Recommendations. Need help selecting the right pump? shows the letter designations for the various types of rod and tubing pumps that are available for different barrel thicknesses and either metal or soft-packed plungers. This 1 1/16-in. 11AX. API Spec. 21. ; N = pumping speed, spm; and D = diameter of the pump plunger, in. Traveling barrel usually keeps sand off hold down assembly. Pump: − Tbg Pumps: largest bore pumps (dPgr just a 1/4” < ID of tbg). and Loudermilk, M.D. 54th Southwestern Petroleum Short Course, 2007, 45-59. This bolt needs to be removed and a longer 3/8" bolt installed in its place. surface stroke, a 48-in.-long plunger with a steel rod string and a designated 2 7/8 × 1½-in. Hein Jr., N.W. in length per 1,000 ft of increased well depth. Quality Systems—Model for Quality Assurance in Design, Development, Production, Installations, Servicing. These changes have incorporated the prior information in API RP 11AR[2] and the NACE International MR 01-76[3] for materials to be used in most production environments.
