METHOD OF ACTION ON OIL-SATURATED INTERVAL OF FORMATION IN HORIZONTAL SECTION OF OIL WELL SHAFT Russian patent published in 2019 - IPC E21B23/14 E21B28/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry and can be used to increase efficiency of impact on oil-saturated interval of formation in horizontal section of oil well shaft. Method comprises well killing with salt solution, extraction of downhole equipment, installation of production of shear-blind preventer, riser on production of X-mas equipment, blowout protection unit, sealing device, as well as an injector with a guiding arch, supply to the horizontal section of the well on the flexible tube of equipment, including a connector with a flexible pipe, set of check valves, emergency disconnector, a circulation valve and a device for plasma-pulse action, closing a calibrated metal wire of a plasma-pulse action device by an operator's command over a cable, explosion in the horizontal section of the well, lifting the downhole assembly with a device for plasma-pulse action, well development and outputting to the mode.

EFFECT: technical result consists in increasing production wells and increasing oil recovery of formations.
