Field test results of the using of upper bit tool
Upper bit tool for improvement of quality of slime removal from vertical and horizontal wells is considered in the article. Results of field tests of the designet upper bit tool are shown. Tests proved the working abilities of the device. Drilling rate increased by 18% on the account of stable removal of grinded slime by circulating fluid. Basic dimensions of working elements have been experimentally defined.
