A method of increasing oil recovery and a device for its implementation

摘要

FIELD: oil, gas and coke-chemical industries.SUBSTANCE: invention relates to a device for increasing oil recovery. Device for increasing oil recovery includes ground control unit, electric cable, downhole device including acoustic radiator, which contains magnetostrictive converter. Electric winding of the magnetostrictive converter is wound on a core of rectangular insulated plates. End faces of core are rigidly connected to end parts of steel housing of downhole device. Gap between surface of electric winding and inner surface of housing has value from 0.5 to 10 mm.EFFECT: high efficiency of oil production.1 cl, 2 dwg
