METHOD FOR TREATING-BOTTOM-HOLE ZONE OF WELL BED

摘要

FIELD: oil and gas production industry. SUBSTANCE: this relates to methods for isolation of well bed by using isolating components which are introduced into isolation zone to be treated. According to method, zone to be treated is filled with isolating component with subsequent introduction of isolating component into bottom-hole of bed by subjecting isolating component to pressure pulses initiated by pulse generator located in bottom-hole zone. Value of pressure pulses is higher by at least 5 MPa than pressure of hydrostatic column of liquid at depth of treatment but not higher than value of bed fracturing. Clearance between internal surface of well and generator body is not over 10 mm. Application of method allows for high efficiency of operations. EFFECT: higher efficiency. 3 cl
