Abstract RU 2254450 C2

FIELD: oil and gas industry.

SUBSTANCE: method includes moving perforator to upper portion of well and concurrently slit is cut in wall of casing string using cutter. Then saw is used to cut slit in productive layer. Perforator is provided with measuring device for measuring value of cut slit, mechanism for connection to wall of casing pipe and calibrated movement. Perforator is provided also with assembly, excluding possibility of perforator rotation. After lowering perforator is pressed to pipe by fixing gear and calibrated displacement. Cutter is used to cut slit with height set by measuring device. Saw is connected to perforation, after that movement of perforator in perforation zone is performed with stable dosed feed by gear for calibrated movement. Device has saw and extending disk cutter. According to invention perforator is provided with measuring means for measuring value of cut slit, holding gear and gear for calibrated movement with driving mechanism in form of rotating wheel. Perforator is provided with assembly for excluding rotation of perforator around its longitudinal axis during movement of perforator along casing sting during perforation.

EFFECT: higher reliability, lower costs.
