| 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. |
