| Abstract: | In 2 years of construction practice, the new attempt was made on wire-line coring drilling technology for deep hole in soft formation about the technical equipment matching, borehole structure design, machine ＆ bit selection and washing fluid. The practice proved that wire-line coring technology was feasible for deep hole drilling in soft formation, and drilling monthly efficiency increased over one time with good borehole quality and lower labor intensity. |
