广泛推行空气吹洗钻进与克服一系列由于孔内水流量引起的技术和工艺困难有关。岩石的含水程度对钻探工作指标具有重要的影响,并在钻进过程中导致不同的复杂事故,在预防和排除这些事故时化费很大非生产时间。当穿进水流量不大的地带时,可使用能改进
The widespread implementation of air-purging drilling is related to overcoming a series of technical and process difficulties caused by the water flow in the holes. Rock moisture content has an important impact on drilling performance indicators and leads to complex and complex accidents during drilling and costly non-productive time to prevent and eliminate these accidents. When you wear into the water flow is not large areas, can be used to improve
