METHOD FOR FRACTURING AND PROPPING OF FISSURES IN SUBSURFACE BED Russian patent published in 1999 - IPC

Abstract RU 2138632 C1

FIELD: oil and gas production industry. SUBSTANCE: method is used in wells for fracturing and propping of fissures in subsurface beds. According to method, down-flow pipe string is installed in well. Liquid for fracturing is delivered into one end of that part of circular space which adjoins fracturing interval. Slurry with propping agents is delivered into one end of circular space with continuation of delivering liquid for fracturing into other end of circular space. Slurry with propping agents is brought through alternative ways of flow penetration to various levels of circular space in fracturing interval with continuation of slurry flow through one end of circular space of fracturing interval and of fracturing liquid flowing through other end of circular space in fracturing interval. Application of aforesaid method increases productivity of subsurface beds containing hydrocarbon or other similar fluids. EFFECT: higher efficiency. 11 cl, 6 dwg
