METHOD AND FACILITY FOR SIMULTANEOUS SELECTIVE TREATMENT OF PERFORATION CHANNELS AND TREATMENT OF BOTTOMHOLE OF CONDITIONALLY ENDLESS THICKNESS LAYER Russian patent published in 2009 - IPC E21B43/25 E21B37/00 

FIELD: oil and gas industry.

SUBSTANCE: invention group relates to field of oil and gas industry and can be used for selective treatment of perforation channels and treatment of bottomhole of layer. Treatment method of perforation channels and treatment of bottomhole includes lowering of movable on pump-compressor pipe (PCP) of facility elements for treatment of perforation channels and treatment of bottomhole, implemented in the form of stator and rotor with channels, pumping the working substance under pressure through the facility. Facility is outfitted by body in the form of section of perforated casing string. Stator is implemented in the form of holed washer, located on-the-mitre to the plane of rotor impeller, outfitted by element, encapsulating space between the stator and facility body. On the outside surface of PCP it is rigidly fixed nipple element and stator. Rotor is located between stator and nipple element and it is implemented in concert with impeller. Lifting-lowering of the facility elements, fixed on outside surface of PCP is implemented by elevator from the surface in the range of the facility body.

EFFECT: treatment of perforation channels and treatment of bottomhole without restrictions simultaneously to treated thickness of perforation interval.
