摘要
本文通过对该地区钻探工艺进行分析,地层结构的介绍,钻孔易坍塌,采用套管护壁,金刚石钻头克取石英岩石的钻进效率分析,对矿区水质的检测,根据所出现的钻探问题,现场及时分析原因,采取有针对性的工艺措施,有效地解决了这些问题,圆满完成了施工任务。
In light of introduction of strata structures, the drilling technology employed in the construction area is analyzed. Dealing with the issues occurred in the process of construction, such as collapse of bore hole, harder rock, high water hardness and kick of drill rod, the treatment had been provided accordingly.
