Specialty Sucker Rod Pump

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. Our gas locking prevention oil well pump adopts a mechanical open-and-close oil inlet valve structure. When the gas enters the cavity of the gas locking prevention oil well pump, the pump valve automatically opens and closes by the reciprocating motion of the pump rod, effectively forcing the exhaust and stabilizing the fluid flow. 2. The inlet valve of the gas locking prevention oil well pump is made of high-strength corrosion-resistant alloy material. The gas locking prevention oil well pump avoids leakage or malfunction due to material fatigue. 3. The inlet valve of the gas locking prevention oil well pump adopts a streamlined guide channel design to make the fluid flow path smooth and continuous, reduce turbulence and resistance, and reduce the probability of release of dissolved gas in crude oil.

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. 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. Sucker rod for high viscosity oil exploitation adopts 0.8m anti-stroke distance design + fluid mechanics optimization, which extends the equipment life by 50% and reduces the annual maintenance cost by 20,000 yuan. 2. Sucker rod for high viscosity oil exploitation has 4 pump diameters (32mm-57mm) to adapt to different well depths and oil products, reducing the comprehensive procurement cost by 25%. 3. Based on the Q=KSN formula, the stroke and stroke frequency are dynamically adjusted, and the theoretical displacement of sucker rod for high viscosity oil exploitation is up to 400m³/d.

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. Our separate layer production oil well pump can be used to pump crude oil from multi-layer wells, which can greatly increase the single well production and crude oil recovery rate. 2. Our separate layer production oil well pump can exploit different oil layers separately, reduce inter-layer interference, and thus increase the overall production of the oil well. Our separate layer production oil well pump is particularly suitable for oil fields with uneven oil layer distribution or significant permeability differences. 3. Our separate layer production oil well pump has a simple pump string and convenient construction and operation.

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. The bottom of the plunger of the thermal recovery sucker rod pump is inlaid with a diamond composite (PDC) scraping ring, and the inner wall of the pump barrel of the thermal recovery sucker rod pump is laser engraved with micron-level flow-guiding lines (Ra 0.8μm) to form a vortex effect to prevent sand deposition. 2. The plunger of the thermal recovery sucker rod pump is made of Inconel 718 alloy (temperature resistance 650℃),the seal of the thermal recovery sucker rod pump is a graphite-metal composite material. 3. The thermal recovery sucker rod pump adopts a floating valve seat design, which automatically compensates for the thermal deformation of ±3mm.
