Specialty Sucker Rod Pump

Eliminate cross-flow interference and maximize production from multi-pay zones with precision-engineered selective recovery solutions.

Specifically designed for heavy oil and high gas-cut wells. The mechanical forced-opening mechanism ensures the valve opens/closes on every stroke, regardless of fluid viscosity.

1. Our inclined well sucker rod pump adopts spring forced seat sealing technology, so our inclined well sucker rod pump solves the industry problem that the valve ball of traditional oil well pumps cannot return to its original position by gravity in inclined wells and horizontal wells. 2. Unlike ordinary oil well pumps that can only be used in vertical wells, our inclined well sucker rod pump can maintain stable operation at any angle of 0-90°. 3. The modular design of the inclined well sucker rod pump allows for quick replacement of pump diameter components (only 2 hours), and the same platform can adapt to different production capacity requirements of 32-95mm. 4. The special flow channel design of the inclined well sucker rod pump enables the viscosity adaptation range to reach 50-5000mPa·s.

1.Large displacement tubing pump has dual working state switching function. Large displacement tubing 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 large displacement tubing 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 tubing 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 large displacement tubing pump connector is switched to the "on" position, the displacement matches the oil inlet return pump, reducing energy loss.

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.Three-acting tandem oil well pump is suitable for oil wells with sufficient liquid supply. 2.Three-acting tandem oil well pump can suck and discharge liquid during the up and down strokes. Three-acting tandem oil well pump has the characteristics of small pump diameter, large displacement, and deep pumping. 3.The special structure of three-acting tandem oil well pump enables three oil suction and three oil discharge actions to be completed in one reciprocating stroke, which can realize multi-layer oil wells.

1. Upward stroke: When the plunger of the heavy oil pump with hydraulic feedback 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 heavy oil pump with hydraulic feedback 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.
