According to the characteristics of turbine drilling at the hole-bottom, by applying mathematics and hydraulic theory etc., the parameters of flushing fluid in the hole annular space were studied and optimized, and a basic and practical equation was set up to help to determine hydraulic friction in scientific drilling. Thus, the relative measures which can reduce fluid moving resistance may be taken to control the pressure effectively in the drilling hole.
