The separate extraction mixed extraction pump developed by our company is suitable for implementing layered production operations on two oil layers, and for oil wells with large pressure differences between the two oil layers.
Structure and principle:
The pump adopts two pumps with different diameters connected in series, with the large pump on top and the small pump on the bottom, forming a dual pump single action oil extraction pump, as shown in the figure.
During homework, use a packer to separate the two oil layers to avoid the influence of interlayer differences. During the upward stroke, the liquid from the two oil layers is drawn into their respective pump chambers through different fixed valve channels; During the downward stroke, the liquid in the two pump chambers is mixed and discharged into the oil pipe through their respective moving valves and plunger inner hole channels.
Main features:
It can achieve layered mining of two oil layers, avoid the influence of interlayer differences, and increase liquid production.
The upper pump is designed with a single valve structure, which is easy to install, reliable in operation, and has low oil flow resistance.
Both the upper and lower pump barrels adopt a bridge type reinforced structure to protect the pump barrel from tensile and compressive deformation.
