摘要
深部找矿勘探给钻探技术提出了更高的要求。钻孔越深,施工周期越长,孔内往往越复杂,施工难度越大。在复杂地层进行深孔钻探更是如此,护壁技术显得尤为重要。结合近年来进行深孔钻探所遇到的问题,对复杂地层深孔钻进泥浆护壁技术进行了较深入的探讨,并在生产实践中对PHP泥浆和新型LBM泥浆进行了试验应用,取得了较好的效果,对深孔钻探施工具有一定的借鉴意义。
More advanced drilling techniques are demanded for deep ore exploration. The deeper a drilling hole is, the longer the construction period would be with more complicated situations in borehole and more difficulties in construction, so wall protection becomes more important. The paper discussed the technique of wall protection with slurry in deep-hole drilling in complicated formation with deep-hole drilling problems in recent years, and presented the test application of PHP mud and LBM mud, which could be the reference for deep-hole drilling construction.
