METHOD FOR INTEGRATED HYDRAULIC AND HYDRO-ACID BREAK OF OIL AND GAS BEDS

摘要

A method for integrated fluid and acid well fracturing includes carrying out perforation works in well, hydraulic and acid well fracturing by means ofinstallation without crack fixation. A packer is installed at needed depth, and acid well fracturing is performed across from the zone of watered layer with crack fixation with proppant. At carrying out acid well fracturing following acids are used: hydrochloric, hydrofluoric and phosphoric acids mixed on the surface as suspension, those are injected at forced pump mode.
