Introduction to Special Oil Pump

Hydraulic feedback thickening pump

The principle of hydraulic feedback pumping is to use the weight of crude oil in the oil pipe to form a hydraulic feedback force, which helps the pumping rod to overcome the resistance of heavy oil and move downwards. The pump consists of two pumps with different diameters connected in series, with the upper part being a large-diameter pump and the lower part being a small-diameter pump. A circular chamber is formed between the lower plunger and the upper pump barrel. During the upward stroke, the oil outlet valve closes, the annular chamber increases, the internal pressure decreases, and the well fluid enters the annular chamber through the lower cylinder disc; During the downstroke, the annular chamber decreases, the pressure inside the chamber increases, and the oil outlet valve opens, allowing the oil to enter the pump's oil pipe. At this time, the hydraulic feedback force generated by the plunger on the pump increases the downward force of the plunger, overcoming the difficulty of the rod column downward caused by the thick oil, and enabling the oil pump to produce normally in the thick oil well.

Specifications and parameters

Deviated well oil pump

The floating valve and fixed valve are equipped with semi spherical valves with guiding samples, mechanical forced reset sealing structure, and increased overcurrent area. The floating valve and fixed valve of this structure can be opened and closed in a timely manner at any inclination angle, with fast closing speed, low oil flow resistance, and high filling coefficient, achieving the goal of efficient pumping in inclined wells.

Specifications and parameters

Sand control rod type oil pump

The pump mainly consists of a rod type oil extraction pump, a top cup fixed seat sealer with a ring valve, inner and outer sand settling pipes, and an integral oil inlet sand settling coupling. The ring valve structure has good adaptability to gas wells; And it reduces the opening pressure of the swimming valve ball, which is beneficial for improving pump efficiency. The anti sand rod type oil pump has good adaptability to oil wells with severe sand production, good anti sand burial and sand jamming effects, and long pump inspection cycles;
