Application new technological methods for struggle against absorption at drilling chinks In conditionsUTM and results of their tests

The given report shines problems connected with absorption technological liquids at drilling operational chinks within the limits of UTM on the top intervals and at drilling a horizontal trunk of a chink in productive horizon. In the report modern technological methods for struggle against absorption technological liquids applied are resulted for the first time at construction of chinks of Eastern Siberia, and in particular UTM. Have been offered and in the further are applied new corking structures, testsare lead of the equipment to drilling and simultaneous fastenings a trunk of a chink pipe for fastening, works on mobilization and the further test of the equipment for drilling chinks with operated pressure are conducted. The first chinks with a horizontal trunk on productive horizon 1000м are as of today drilled and in times the quantity lost on absorption technological liquids is reduced
