Two-lift unit for simultaneous separate operation of two layers of a single well in conditions complicated by removal of mechanical impurities from the upper reservoir

摘要

The utility model refers to the oil-producing industry, namely, oil production with simultaneous-separate operation of two seams by a single well in conditions complicated by removal of mechanical impurities from the upper reservoir.;The technical task of the utility model is to increase the reliability of the two-lift installation for simultaneously separating the two seams from one well by providing protection against clogging of the sucker pump that extracts the products from the upper object.;A two-lift unit for simultaneously separate operation of two formations by one well in conditions complicated by removal of mechanical impurities from the upper reservoir includes a main and auxiliary drives, a packer installed between the upper and lower production formations, the main one communicated with the sub-packer space of the well and the additional with over-packer well space, a string of elevator pipes with sucker-rod pumps fixed to the wellhead with double-bar reinforcement, parallel An armature mounted on both columns of the elevator pipes and configured to fix them relative to each other. At the same time, the bottom of the additional column of elevator pipes between the sucker pump and the parallel armature is equipped with a branch pipe with filtration apertures, two or three tubing, acting as a slurry collector, and a plug in the form of a disk installed in the coupling. 1 yl.
