摘要
中原油田自１９９５年以来开始进行了老井开窗侧钻小眼井技术，数年的努力形成了一套完善工艺。文中分析了开窗位置应遵循的原则，斜向器的定向和固定，套管的开窗及修窗的方法，以及对小眼井钻井技术中钻头的合理选择，螺杆钻具的使用，小眼井轨迹的控制，钻井液、完井技术的合理选择作了分析。
Since 1995,sidetracking operations have been conducted in Zhongyuan Oilfield,and a set of perfect slim hole sidetracking technology has been formed.This paper introduces the method used to decide the location of casing window,orientation and fixation of whipstocks and method of casing window.And it also analyses bit selection,use of screw drill tool,slim hole trajectory control,and rational selection of drilling fluid and completion technique.
