Sucker rod pumping installations for dual OIL RECOVERY FROM TWO

摘要

Sucker rod pumping installations for dual production of oil from two reservoirs relates to the oil industry. The object of the utility model is to improve the accuracy of separate accounting for the two layers production by the suspension of the selection of the wells of the upper stratum of production and conservation of the lower layer selection of products at the working equipment. The rock pump device for dual extraction of oil from the two layers, comprising two pumps with different diameters, the plungers of which are coupled between a branch pipe, lateral suction upper pump valve, the hollow cylinder of the upper plunger, inside which there are arranged vertical channel with a discharge valve forming a hollow cylinder concentric cavity and connected to the horizontal channels communicating with the pump intake upper string of tubing, packer, uncoupling formations shank Cpd sculpt receiving the lower pump packer space borehole logging cable with depth gauge, deflated the annulus at the reception of the lower pump, characterized in that the cylinder bottom of the pump is made composite of the two equal diameter cylinder and polished rod rod string is elongated by the amount of cylinder extension lower pump.
