| Abstract: | The characteristic of wire line coring drilling in deep hard formation is that there is a contradiction of bit pressure increasing limited by bit slipping. Based on the successful experience of the extra-deep well construction of Taigou iron mine, the paper put forward the technical measures of impregnated diamond bit selection and application for improving drilling efficiency and prolong bit service life to solve bit slipping in deep hard formation drilling. |

| Keywords: | deep hard formation drilling wire line coring impregnated diamond bit slipping formation |
