Abstract

The method includes drilling of sage shaft by means of turbo-drill, with casing of each stage. After casing lower stage of shaft one disconnects from string of drill pipes the bottom section, with length equal to sum of lengths of the lower stage of well and depth of design mark from end of lower stage, and instead of disconnected part of drill string one installs turbo-drill output shaft of which is connected to string of drill pipes with length equal to length of disconnected part, with drilling to design depth.
