连续流量法中钻屑与瓦斯动态分离技术
Dynamic separation technology of drill cutting and gas in continuous flow method
摘要
Abstract
To overcome the defects in gas emission initial velocity method, a technology of dynamic separation of drill cuttings and gas has been developed in this study. The migration characteristics and influencing factors of gas leakage, leakage rate curve are investigated using theoretical analysis, orthogonal experimental method and single index range analysis. The results show that: the method of dynamic separation of drill cuttings and gas is feasible in engineering practice; the factors influencing the gas leakage includes the length and diameter of drillhole blocking, the size of drill cuttings, the total flow of drill emission gas, and the rotational speed of electric coal drill. Among these factors, the size of drill cuttings is more important than the rotational speed of electric coal drill, far more important than the length of drillhole blocking. The study has a reference value and guiding significance for the improvement of gas emission initial velocity method.关键词
