摘　　要：准噶尔盆地阜康凹陷东环带钻探面临着区域地层压力系统复杂、地层非均质性强、钻探目的层头屯河组水敏性强等主要技术难点。为此,从该区地质资料分析、基础理论研究着手,开展了优化井身结构,优选钻井液体系、PDC钻头型号等钻井技术现场试验,制定相应钻井提速配套技术措施。研究认为:聚合盐钻井液体系具有润滑防卡效果好、防塌效果优良等优点。PDC+螺杆钻具组合在白垩系上部及侏罗系中上部地层可大幅提高机械钻速。There exist some difficulties during drilling in the east ring belt of Fukang sag, Junggar Basin, containing complicated formation pressure system, strong heterogeneity, and strong water sensitivity of Toutunhe Formation, the drilling target. So, we implemented lots of researches, such as, to optimize the casing programme, to carry out some field experiments on optimizing the drilling- fluid system and PDC bit, and to formulate some matching measures against increasing drilling speed.
