| 中文摘要:大同盆地北部油气预查施工区地层主要为泥岩、砂质泥岩、炭质泥岩和砂砾岩不等厚互层。上部砂砾层胶结松散、破碎，易掉块坍塌；泥岩水敏性强，易分散造浆，护壁困难，钻进中易产生卡钻及粘附卡钻。设计井深一般为1000～3000 m，钻进中合理采用了不同类型、结构的钻头，钻具和取心工具，调整了钻进技术参数，并选用了双聚-成膜无固相钻井液体系及其它相应的工艺技术措施，孔壁稳定，保证了正常施工。其中也顺利完成了侧钻井施工任务，均取得了较好的效果。 |

| Abstract:In the oil and gas pre-exploration in northern part of Datong basin, the construction area formation is interbedded mainly with mudstone, sandy mudstone, carbonaceous mudstone and sandy conglomerate, loose cemented gravel in upper part, which are broken with block falling, and mudstone has strong water sensitivity and is easy to disperse and mud making, wall protection is difficult, blocking and sticking occur in drilling process. The designed well depth is generally 1000～3000m, different types and structures of drill bit, tools and coring tool are adopted, drilling parameters are adjusted. Dual polymer filming non-solid drilling fluid system is selected together with corresponding technological process and measures to realize wall stability and the side tracking are successfully completed. |
