BOREHOLE RUNNING IN METHOD Russian patent published in 1995 - IPC

FIELD: mining industry. SUBSTANCE: method provides for stratums opening by drilling. Then they make test of stratums by stratum testers, exercise probe running and go to industrial running of boreholes. The method is exercised after discovery of industrial stocks of oil and gas. After detection of intervals of complications and prospective stratums diameter of borehole is expanded in the intervals. Borehole is compressed by expanding pipes casing. Then pipes outer space is grouted by hardening liquid, expanding pipes perforation is exercised in zone of prospective stratums. In stratums probe running and industrial running test process packers are mounted in the same places. They are They are mounted inside expanding pipes casing. EFFECT: boreholes running in method is used in mining industry.
