摘　　要：针对新疆油田莫116井区上部地层膏质泥岩易缩径及下部地层井壁垮塌难题,设计优化出了胺基钻井液的配方,并在MB6001、MB6293、MB6136等井中进行了成功应用。现场应用表明,胺基钻井液抑制性能优良、井壁稳定、井径规则,平均井径扩大率小于6%,能解决莫116井区钻井过程中常出现的井壁失稳、膏质泥岩造浆严重、钻头易泥包、缩径卡钻、钻速慢等技术难题,为莫116井区的高效开发提供了技术支撑与储备。Down problems are encountered in Area Mo-116 of Xinjiang oilfield,such as tight hole in upper gypsum mudstone formation and caving in lower formation,and the amine-based drilling fluid formulation is optimized,which is applied in wells MB6001,MB6293 and MB6136 successfully.Application results show that the amine-based drilling fluid has characteristics of good inhibitive capacity,borehole stability,regular borehole diameter,and the average borehole diameter enlargement rate is less than 6%,which overcomes the problems in that of caving,mud making,bit balling,tight hole,pipe stuck,and poor ROP.
