摘要
通过对栗木锡矿复杂地层的分析,采用绳索取芯技术,多级套管根管技术,优质泥浆护壁堵漏等钻进工艺,并对孔内事故的预防与处理提出了一系列措施,成功解决了该区深孔钻进的难题,取得了很好效果。
After analyzing the complex strata of Limu Sn deposit, we have successfully overcome the difficulties that happened during deep-hole drilling and gained an ideal effeet by applying the drilling erafts like wire line coring, multi-grade casing root canal, using high quality slurry to protect walls and plugging with a series of measures for preventing and disposing the accidents happened in drilling hole.
