| 摘 要： | 河南三门峡勘探区地质构造复杂,小断层多,岩石倾角大,其上部马头山砂岩层及下部泥岩、页岩层,极易发生孔壁坍塌掉块事故。在钻进施工中,根据发生坍塌掉块的不同情况,分别提出粘泥护孔、水泥护孔和泥浆护孔等处理方法,并采取相应钻进技术措施。经生产实践验证,该地区的施工处理方法及技术措施可有效预防孔内事故,提高钻效。

| Abstract: | Geological structure is complex in Sanmenxia exploration area, Henan. There are many minor faults and rather large strata dip, coal measures upper part Matoushan sandstone and lower part mudstone and shale are easy to bring on borehole wall collapsing during drilling. According to different instances, respectively employ glutinous clay, cement and mud slurry wailing up treatments and corresponding drilling technical measures. Through practical validating, the treatments and technical measures adopted in the area can effectively prevent drilling accidents and improve drilling efficiency. |
