Abstract

Method for well drilling in non-stable rocks includes destruction of rock with back washing and support of rock walls of the well with pressure of washing liquid. To increase effectiveness and reliability of drilling through exclusion of dirty well in well bottom zone one forms counter-motion of washing liquid and drilled rock.
