在分析现有潜孔钻机工作特性的基础上，提出了运用数理统计理论寻求钻孔工作参数与钻孔速度和钻孔质量之间的关系，通过试验研究得出描述其间规律的回归方程，为优化潜孔钻机的钻孔工作参数提供了理论基础和实践指导。
Based on the analysis of the working characteristics of existing DTH drilling rigs, this paper proposed the relationship between drilling parameters and drilling speed and drilling quality by applying mathematical statistics theory. The regression equation describing the law between them was obtained by Optimizing the drilling parameters of a downhole drilling machine provides theoretical basis and practical guidance.
