The third phase of the Chang ''e project has realized the exploration and sampling of the moon. In order to further explore the feasibility of the deep moon， the orthogonal test is designed based on the optimization of drill bit and drilling procedures in deep drilling.The effects of bit type and drilling schedule parameters on drilling efficiency and power consumption are analyzed. The results showed that the PDC bit outperformed other types of bits with the rate of penetration（ROP） of up to 3.98mm/s and a moderate drilling power consumption. The changes in drilling efficiency and power consumption caused by drilling procedures are studied from the angle of influence degree of test factors， coring effect and cutting-removal ability， and the relationship among rotational speed， weight on bit and pump volume and drilling rate and power is obtained by combining theoretical model. Based on the test results， the optimal bit type and drilling schedule combination are preliminarily selected to provide technical support for subsequent drilling tests.
