PLANT FOR OIL RECOVERY OF TWO ONE WELL

摘要

The proposal relates to oil-producing industry and is intended for the production of oil from one well of two layers with parallel suspension deep plunger pumps. Installation for recovering oil from one of two well layers includes parallel pipe string with deep plunger pumps, deflated at respective columns of rods. Columns of rods joined at the mouth of the flexible member, with opposite reciprocating movement by means of a drive formed as a double-acting hydraulic drive, wherein the flexible element is equipped with a piston system, placed in the hydraulic circuit. Furthermore, the flexible member is coupled with the columns of rods of the mouth above the wellhead stuffing box. The proposed installations for production of oil from one well of two layers has a simple structure and a low metal content, besides, no fluid couplings, V-belt and chain transmission substantially increase the efficiency of the installation, in connection with which its work becomes more efficient. 1 Fig. to 1 liter.
