The sand control oil well pump adopts a long plunger, a short pump barrel and a sand settling lateral oil inlet structure. It is mainly composed of: long plunger, short pump barrel, two-way joint, sand settling outer barrel, oil inlet and outlet valve, hydraulic connection pump sand ring and other components.

The sand control and sand grinding is to use the combined action of the sand retaining ring and the leaking liquid to prevent sand particles from entering the sealing gap between the plunger and the pump barrel, thereby eliminating sand blockage, reducing the wear of the pump barrel and the plunger and protecting surface reinforcement. After the oil well stops the pump, the sinking sand will sink into the lower liner of the pump along the sand settling annulus, and will not accumulate on the pump like a conventional pump, preventing the sand from adhering to the sucker rod.

 

① The sand control pump can prevent the sand from being buried in the sucker rod when the pump is stopped, and can prevent the sand from clogging the plunger during the working process. In particular, it can effectively prevent sand particles from entering the sealing gap between the plunger and the pump barrel, causing damage to the pump barrel and the plunger. Severe wear and tear. Due to the reduced wear, the surface strengthening layer of the plunger and the pump barrel is not easily damaged, and the substrate is not in direct contact with corrosive media. Therefore, with the same surface treatment process, its corrosion resistance is better than that of conventional pumps.
② Damage to the oil pump used in sand-bearing oil wells is the main cause of excessive valve leakage or clearance leakage. The pump can effectively prevent sanding and reduce corrosion, thereby greatly prolonging the service life of the pump.
③The oil output resistance of the sand control pump is small, there is no blockage when it is lowered, and the lower rod column is not easy to bend, which improves the local wear of the rod tube.
④ There are no special requirements for the sand control pump during use. All valves and bonnets are made from standard parts. Disassembly is also very convenient. All oil extraction plant tool teams are capable of maintenance.
