Separate Layer Production Pump

Introduction of Layer Separated Sucker Oil Pump:

In response to the problem of multi-layer system and inter-layer contradictions in oil wells, our company has developed a layer separated sucker oil pump. The layer separated sucker oil pump uses the same pumping unit and the same set of sucker rods to simultaneously exploit the oil of two or more oil layers in the same wellbore. Layer separated sucker oil pump is mainly used for layered production, eliminating or reducing the interference between oil layers. Layer separated sucker oil pump is conducive to increasing oil well production. Layer separated sucker oil pump is suitable for pumping wells with sufficient liquid supply capacity, small sand output, not serious wax deposition and serious interlayer interference.

Structure of Multi-layer Oil Well Sucker Pump:

The structure of our company's multi-layer oil well sucker pump is mainly: upper oil outlet valve, upper plunger, diverter valve, upper pump barrel, hollow connecting rod, eccentric valve, lower plunger, packer, lower oil outlet valve, lower pump barrel. Our layered oil production sucker pump uses a unique double liquid inlet to prevent the liquids in the two oil layers from affecting each other.

Working Principle of Multi-layer Oil Well Sucker Pump:

The upper and lower pumps of the multi-layer oil well sucker pump work at the same time, and the upper pump works in the annular space formed by the difference in diameter between the upper and lower plungers. The upper oil of the multi-layer oil well sucker pump enters the annular space through the eccentric valve and is then discharged through the diverter valve. The lower layer oil of efficient linear rod pumps in oil and gas industry enters the lower pump barrel through the lower pump inlet valve, and then is discharged from the lower pump outlet valve. After being mixed with the upper layer oil through the diverter valve, it is discharged from the ground together. Our efficient linear rod pumps in oil and gas industry can be used to pump crude oil in multi-layer wells, which can greatly increase the single well production and crude oil recovery rate, effectively reduce production costs, and have high comprehensive economic benefits. During production, the two interfering oil layers of efficient linear rod pumps in oil and gas industry are separated by a layer packer. The upper and lower plungers of the layered oil pump reciprocate in the pump barrel to pump the liquids of oil layers A and B into the upper and lower pumps respectively, and discharge them through the oil pipe. When the Layered oil production sucker pump is in the upward stroke, the upper and lower plungers move upward synchronously, the upper movable valve closes under the gravity of the liquid column, the suction chamber volume of the two pump barrels increases, the pressure decreases, the bottom fixed valve and the eccentric oil inlet valve open, and the A and B oil layer liquids enter the upper and lower pump barrels respectively to complete the suction process. When the Layered oil production sucker pump is in the downward stroke, the two plungers move downward at the same time, the bottom fixed valve and the eccentric oil inlet valve are closed, the two movable valves and the diverter valve are opened, and the liquid in the lower pump flows into the upper pump plunger through the lower plunger and the self-aligning joint, and mixes with the liquid flowing into the upper pump through the diverter valve, and discharges the liquid to the pump oil pipe together.
