METHOD FOR DUAL COMPLETION OF WELL USING TRAVERSE Russian patent published in 2021 - IPC E21B43/14 

FIELD: oil industry.

SUBSTANCE: invention relates to the oil industry and can be used in the operation of oil production wells with equipment for double-lift dual completion (DC). The method includes dual completion of two layers through one well with pumps located on two parallel tubing strings using two ropes attached to a common traverse. A two-lift system of simultaneous-separate operation of two layers is used, a rocking machine or a chain drive is used as a ground drive, in which two rope suspensions from a converting reducing mechanism in a chain drive are thrown over a rope pulley, or the ropes are attached to the head of the balancer of the pumping machine, after which is why a double traverse is attached to the ropes with a length of 350-450 mm, a width of 120-180 mm and a height of 60-70 mm, which has four solid holes located in one line along the major axis of the traverses. Two holes are external with a diameter of 30-40 mm and are intended for attachment to two ropes, two other holes with a diameter of 35-40 mm are located on the inner side of the traverse and are intended for attachment to two polished rods. The distance between the inner holes is 90-110 mm, each of the rods with corresponding tubing and a sucker rod pump is adjusted and tuned to work on one of the two layers, after which the well is put into operation.

EFFECT: increased efficiency of well operation with double-lift DC, increased reliability.
