Sucker Rod Pump

1. The API rod pump can be lowered into the tubing as a whole along with the sucker rod. When checking the API sucker rod pump, there is no need to lift and lower the tubing, which greatly shortens the operation time. Since the operation time is shortened and the number of times the tubing is unfastened is reduced, the service life of the tubing is extended. 2. The sealing support joint of the API rod pump is universal with the tubing. When changing different pump diameters, there is no need to adjust the tubing string of the API rod pump, which reduces maintenance costs. 3. The API rod pump produced by our company has a wide range of applications, suitable for thin oil wells, heavy oil wells, high condensate oil wells, steam drive wells, deep wells, sand-containing wells, gas-containing wells, etc. The API rod pump solves the current problems of sand production in heavy oil wells.

Engineered for sandy and high-viscosity wells. Our lateral oil inlet design prevents sand accumulation, extending pump life in the harshest environments.

1. Thin oil well sucker oil pump adopts modular design. The core components such as pump barrel, plunger, valve and so on adopt standardized and independent module design, which is convenient for disassembly and replacement. 2. All parts of Thin oil well sucker oil pump can be replaced by conventional oilfield tools without special equipment. 3. Thin oil well sucker oil pump is suitable for low pressure, low liquid level and low liquid production wells, solving the problems of difficult start-up and unstable oil pumping of traditional pumps.

1. When the sucker rod is lifted 200mm, the plunger of the rod pump for steam injection thermal recovery is lifted synchronously through the mechanical linkage device to connect the steam injection hole of the sealing tube with the oil pipe. 2. The channel of the rod pump for steam injection thermal recovery adopts a high-temperature resistant alloy (Inconel 625) bushing, which can withstand continuous steam scouring at 350℃. In the field test of Liaohe Oilfield, the steam dryness retention rate is ≥85%. 3. When the plunger falls back, the cone surface (tolerance ±0.01mm) of the rod pump for steam injection thermal recovery forms a metal seal with the pump barrel, and the sealing pressure reaches 15MPa.

1. Downhole pump plungers can effectively reduce oil leakage and can withstand long-term friction. 2. Specialty spray metal plunger has passed API 11AX and ISO 9001 standard certification, and the quality of special plunger is guaranteed. 3. The wear resistance and corrosion resistance of specialty spray metal plunger make it efficient and stable in oil drilling and mining.

1. Upward stroke: When the plunger of the heavy oil recovery downhole pump moves upward, the upper liquid enters the lower chamber through a specially designed feedback channel to form hydraulic energy storage. 2. Downward stroke: The stored hydraulic energy is converted into auxiliary thrust (actually measured up to 2-5kN), and the super heavy oil injection and production downhole pump can effectively overcome the resistance of heavy oil. 3. Pressure balance design: The heavy oil pump with hydraulic feedback uses our original two-way flow channel structure to balance the pressure inside and outside the pump in real time to avoid air lock and sand jam.

1. Three-acting tandem oil well pump: Up to 30% higher discharge efficiency vs conventional rod pumps. 2. Triple-chamber design ensures continuous and stable fluid output. 3. Suitable for high-volume and deep well production conditions.

1. Petroleum brass chrome-plated pump barrel adopts double anti-corrosion structure of brass base and hard chrome plating, which is resistant to strong acid, strong alkali and seawater corrosion. The service life of chrome brass barrel for oil pump is more than 2 times that of ordinary stainless steel barrels for sucker rod pumps. 2. Chrome brass barrel for oil pump is hygienic and safe, perfectly matches the plunger, and effectively prevents medium leakage. 3. Brass pump barrel has passed ISO9001 and API11AX certification, and the whole process from raw materials to finished products is tested. The performance of each chrome brass barrel for oil pump is stable and reliable.

1.Large displacement tubing pump has dual working state switching function. Large pump diameter sucker rod pump can operate in two different working modes through the switch connector between the upper plunger and the lower plunger. 2.Due to this dual working state, the oil well pump can still maintain efficient operation under the condition of temperature and viscosity changes. When the wellhead temperature drops and the viscosity increases, the switch connector switches to the "open" position and continues to work efficiently. 3. When the large displacement sucker rod pump switch connector is in the "off" position, the displacement of the pump is the same as the size of the upper pump. When the specialty rod pumpp connector is switched to the "on" position, the displacement matches the oil inlet return pump, reducing energy loss.

1.​‍​‌‍​‍‌​‍​‌‍​‍‌ RWB API insert pumps are capable of operating under a variety of conditions, e.g. low-sand wells and low-level wells, and the certification by API assures the quality of the product to be reliable.​ 2. RWB API insert pumps feature a high flow rate and a wide inner diameter pump cylinder, which facilitate enhancing the daily oil production of a single well.。 3. The oil rod pump consists of a fixed bottom + fewer connection design, which helps in significantly minimizing potential failure and wear. ​‍​‌‍​‍‌​‍​‌‍​‍‌
