摘要
I38H井是渤海某油田调整井中的一口先期排液水平井,后期转入注水作业,为满足周边3口井的注采关系,设计水平段长达827.0 m,同时该井为一口目的层位于明化镇、水垂比达2.47的浅层大位移井,为安全、顺利实现钻井作业,通过对I38H井井身结构的优化、井眼轨迹的合理设计以及贝克旋转导向工具和随钻扩眼器等工具的使用,最终成功完成钻井作业。
I38H is a prior drainage horizontal well in adjustment wells of Bohai oilfield,which was used for injection in later stage. 827. 0m horizontal section was designed to satisfy injection-production relation of 3 wells in the surrounding. I38 H is also a shallow displacement well with horizontal and vertical ratio of 2. 47. For the safety of drilling operation,by the optimization of hole configuration,rational design of wellbore trajectory,the use of beck rotary steering tool and the reamer while drilling,well I38 H drilling operation was successfully comleted.
