摘　　要：肯基亚克油田位于西哈萨克斯坦滨里海盆地东缘肯基亚克构造带上,区域构造属于乌拉尔—恩巴盐丘构造带,是典型的以下二叠统孔谷阶(P;)盐丘为核心的穹窿短轴背斜。下二叠统孔谷阶、阿尔琴阶、萨克马尔阶储层地层压力高,钻井液密度高,地质条件复杂,钻井液密度安全窗口窄小,恶性井漏引起的卡钻、溢流等事故频繁,个别井发生井喷。近年来,西部钻探阿克纠宾项目在该区块加强地质研究,加强工程地质一体化协作,强化一次井控,加强井喷事故预防上做了大量的工作,形成了一套复杂地层钻井井控安全技术方案,取得了良好的效果。The Kenkiyake oilfield is located on the Caspian Basin in West Kazakhstan of Kenkiyake structural belts which was a part of Ural-Enba salt dome structural belt.It is a emblematic short-axis anticline which was center on Lower Permian Kongguian(P;)salt dome.Higher formation pressure and mud density,narrow mud interval,complex geological conditions was the characteristic of the Lower Permian Konggu,Alqenian,and Sakmalian reservoir stratum.Frequent accidents such as sticking,even overflow was caused by lost circulation.In recent years,the Aktobin project of Western Drilling has strengthened the integrated cooperation of geological research and engineering geology in this block,and has done a lot of work in strengthening primary well control and blowout accident prevention,forming a set of safety technical scheme for drilling well control in complex formation,and achieved good results.
