中文摘要:以自主研发的φ219.1/168.3 mm大口径气举反循环钻具生产试验获得的基础数据，对影响气举反循环钻进效率的各种因素进行了初步分析，得出了钻速与沉没比和风量有一定相关性，与风压关系不大的结论。

Preliminary Analysis on Influence Factors of Air-lift Reverse Circulation Drilling Efficiency to Large Diameter Engineering Well
Abstract:φ219.1/168.3mm large diameter reverse circulation drilling tool is independently developed by Coalfield Geology Bureau of Henan Province, which has been successfully applied to large diameter engineering well with good results. In this paper, the preliminary analysis is made on various factors affecting air-lift reverse circulation drilling efficiency based on the basic production test data, it is concluded that the drilling rate has certain relevance to sinking ratio and air volume, but with little relationship to air pressure.
