FIELD: oil industry.
SUBSTANCE: invention relates to oil industry and can be used in operation of oil producing well. Proposed method comprises lowering and tight fit in packer above productive formation of packer with branch pipe made with possibility of tight interaction with nipple lowered from wellhead. Descending into the well at rod of sucker-rod pumping unit – SRPU with lock on cylinder until tight interaction with locking support. Product extraction. Before lowering, the packer branch pipe is equipped with a lock support and a guiding cone from above. Nipple is equipped with a lock for a lock support. At the same time the SRPU is lowered into the production string after technological exposure of the working agent in the bed and recovery of the tubing. SRPU is used in form of plug-in sucker-rod pumping unit with cylinder of preset diameter arranged on branch pipe connected to casing string and providing expansion of functional capabilities.
EFFECT: technical result is higher efficiency of method due to its simplification.
