摘　　要：我国“嫦娥”工程第三期已经实现对月球的探测及取样。针对进一步月球深部的可行性探索,本文基于月面深部钻进钻头及钻进规程的优选问题,设计正交试验。分析钻头类型和钻进规程参数对钻进效率和功耗的影响。试验结果表明,PDC钻头以高达3.98 mm/s的钻速及中等的钻进功耗远优于其他类型的钻头。从试验因素的影响程度、取心效果和排屑能力的角度研究钻进规程引起的钻进效率和功耗的变化,结合理论模型得出转速、钻压和泵量与钻速和功率之间的关系。针对试验结果初步优选出最佳钻头类型和钻进规程组合,为后续钻进试验提供技术支撑。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.
