FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry and can be used at simultaneous separate operation of two well formations. Plant for simultaneous separate operation of two well formations comprises a well head, a long flow column, a main sucker-rod pump, a packer separating upper and lower formations, additional pumping unit and a short riser pipe installed above the upper productive formation, and a parallel anchor installed on both columns of flow tubes and above the upper productive formation. Short column of tubing is equipped with an additional sucker-rod pump, and the main and additional sucker-rod pumps are plug-in ones, at that reception of each of them is interconnected by borehole space through shank with filter. Mesh filter in shank located under packer is fixed with bottom clearance down blind cup with radial channels, inside which there is a hollow sleeve with spring-loaded upward and with narrowing inside, installed with possibility of longitudinal movement and hermetic overlapping of radial channels of the cartridge in upper position. Main pump from below is equipped with pusher configured to interact with sleeve contraction and its displacement downward relative to sleeve to open radial channels before fixation in packer.
EFFECT: technical result consists in possibility of quick separation of formations after extraction of main pump from packer installed between formations.
