| 中文摘要:彭阳草庙地区是宁夏南部山区深部煤炭资源勘查的重要地区之一。在钻探过程中，多数钻孔都遇到不同程度的漏失问题，部分钻孔由于漏失诱发了孔内事故或机械事故，最终导致报废。在现场调研的基础上，针对不同漏失地层的防漏堵漏对策进行了分析；通过室内试验评价得到对应的防漏堵漏配方与实施细则；在以ZK7-1孔为代表的多个钻孔展开现场试验，效果良好，可在该地区或国内类似地区进行推广。 |

| Abstract:Caomiao area of Pengyang County is one of important sites of deep coal resource exploration at mountainous area of southern Ningxia. Lost circulation is very common during drilling, which induces borehole accident and mechanical failure, even leads to abandonment of the borehole. Analysis was made on countermeasures for leakage protection and sealing in different formations, and corresponding formulas and operating details were obtained through laboratory tests. Field tests were also made with representative of ZK7-1; it is showed the lost circulation was controlled effectively, the leakage protection and sealing technology could be popularized in similar geological condition. |
