钻井参数与钻机性能间的量化关系

摘要

A quantified relationship between shaft drilling parameters and drilling machine performan -ces always is a weak link in a research on the shaft drilling engineering. With a quantified analysis ,a introduction on a conception of a rock breaking specific power and a derivation calculation conducted , a quantified relationship between the shaft drilling parameters and drilling machine performances was provided.In the engineering practices ,the research on the quantified relationship could be applied to optimize the parameter design on the shaft drilling technique and to improve the actual application effi ‐ciency of the drilling machine.Based on the variation conditions of the shaft drilling technical parame ‐ters ,the level of the drilling machine performances played could be predicted ,the drilling machine acci‐dent occurred could be prevented and the construction target could be scientifically and rationally real ‐ized.%钻井参数与钻机性能间的量化关系问题，一直是钻井工程研究中的薄弱环节。通过量化分析，引入破岩比功概念，并对其进行推导计算，给出了钻井参数与钻机性能间的量化关系。在工程实践中，可通过研究该量化关系，优化钻井工艺参数设计，提高钻机实际使用效率；并可根据钻井工艺参数的变化情况，预测钻机性能发挥水平，防止钻机故障发生，实现科学合理的施工目标。
