SUCKER ROD PUMP UNIT FOR SIMULTANEOUS-SEPARATE OPERATION OF TWO RESERVOIRS Russian patent published in 2016 - IPC E21B43/14 F04B47/02 

FIELD: oil and gas industry.

SUBSTANCE: unit includes a flow column, a packer, a liner and a sucker rod pump with a side hole in the cylinder, dividing this cylinder into two parts proportional to the capacities of appropriate reservoirs, located in the casing above a two-channel body, in one channel there is an additional suction valve with an output to the clearance between the casing and the cylinder, and the second channel is connected with an input of the sucker rod pump, inputs of the first and second channels are connected with the above packer space of the well and the liner or vice versa. According to the invention the sucker rod pump is made assembled with elongated bottom collar securing and an anchor shoe, connected with an output of the two-channel sub. The clearance between the cylinder and the casing above the side hole of the cylinder is tightened by the sealing coil with collars and lock element, that by the top end is connected with a fit-in branch pipe, equipped at the joint with the flow column by the turned over anchor shoe for mechanical securing of the inserted pump, and the top part of the cylinder has a turned over lock of the appropriate top mechanical securing. Wherein the top surface of the O-ring of the anchor shoe is located below the spring end of the turned over lock at the distance equal from the side hole of the cylinder to the middle of the lock element of the sealing coil.

EFFECT: reduced volume of works performed at the facility during yield and water cut determination of each operated reservoir.
