| 中文摘要:新疆阿勒泰地区阿舍勒铜矿地层是以凝灰岩、角闪岩为主的典型蚀变性水敏地层，地层倾角较大，岩石各向异性明显，钻进过程中极易造成钻孔偏斜。该矿区坑道钻探施工中缩径、坍塌、掉块卡钻等钻探事故频发，制约了防斜、纠斜钻进工艺的选取，使该矿区钻探施工很难满足快速、经济的地质找矿要求。通过对已施工钻孔水敏地层防斜、纠斜工艺进行研究，提出了一套水敏地层防斜、纠斜等提高钻孔质量的工艺措施。 |

| Abstract:Ashele copper mine in Xinjiang Altay region is in typical altered water sensitive formation mainly with tuff, amphibolite, large stratigraphic dip and obvious rock anisotropy, borehole is easily deviated in drilling process. The frequent accidents of hole shrinkage, collapse, block falling and sticking restricted the selection of deviation prevention and correction technologies, which makes it difficult for the field drilling construction to meet the requirements of fast and economic geological prospecting. By the analysis on deviation prevention and correction technologies in the constructed water sensitive formation, a series of technical measures of deviation prevention and correction in water sensitive formation is presented to improve the quality of drilling hole. |
