根据某矿银上矿区外围深部普查找矿勘探15个钻孔(总进尺近万米)施工的经验,谈谈我们应用优质泥浆配合多层套管钻进中深孔(600~1000m)长孔段不稳地层的体会。
According to the experience of the construction of 15 drilling (total footage of nearly 10,000 meters) in a deep general survey on the periphery of a mining area of Yinchuan Coal Mine, let’s talk about the application of high-quality mud and multi-layer casing to drill long holes (600-1000m) Unstable stratum experience.
