| 摘 要： | 在岩溶地区进行水井钻探施工中,常见溶洞、裂隙串等复杂地层,给施工带来了较大的困难.本文以近年在贵州省实施的地下水勘查项目中,分别选择了白云岩地区与灰岩岩石地区的一水井施工为贯通式空气潜孔锤反循环钻进的实验场,通过施工实践,总结了该工艺在岩溶地区的参数体系特征.以此为基础,经应用解决了岩溶地区溶洞、裂隙串等复杂地层的钻进问题,并取得了较好的效果.

| Abstract: | When we drilling in wells in the karst area, karst cave, fissure on common complex formation, and bring bigger difficulty to construction. In this paper, as the groundwater project in Guizhou province re- cently for example, the author choose a well construction of dolomite and limestone rock area for Through Type DTH hammer reverse circulation dr/lling experimental field, through practice, we summed up the characteris- tics of system parameters of the process in Karst area. On this basis, on the drilling problems, and achieved good results. application of the karst cave, fissure |
