Abstract: Hot dry rock has the characteristics of high hardness, poor abrasiveness, poor drill-ability, difficult drilling and so on; in drilling, a conventional impregnated diamond bit is easy to slip or quickly wear out. Aiming at these technical problems, we developed a bionic abnormal shape bit to improve its wear-resistance, and the bit was made with referring to a pangolin claw toe as a bionic prototype and combining with the structure and manufacturing techniques of impregnated diamond bit. In field drilling tests of the hot dry rocks in Gonghe County of Qinghai Province, no slip occurred with the bionic abnormal shape bit. Compared to the conventional impregnated diamond bit, the drilling speed of the bionic abnormal shape bit increased by 97.5%, and the life span (bionic drill life is calculated life) increased by 1.268 times. It is proved that the bionic abnormal shape bit can improve drilling efficiency, shorten drilling cycle and save drilling cost in a hard and slippery hot dry rock formation.

Key words: bionic abnormal shape bit, pangolin claw, hot dry rock, Gonghe County, Qinghai Province
