埕北油田A22hs井是利用A22井平台修井机完成的一口侧钻水平井,井深2214m,水平段长280·45m,按照设计最终新老井眼合采,实现四级完井。在A22hs井的钻井作业中,主要遇到了膨胀管膨胀作业、开窗作业和固井作业问题,对此进行了原因分析,提出了解决方案和一些改进意见,为下一步类似作业模式提供了经验。 A22hs well in Taobei Oilfield is a sidetracking horizontal well completed by A22 well drilling rig with well depth of 2214m and horizontal section of 280.45m. According to the design of the new combined old and the new wellbore, a four-stage completion is achieved. In A22hs well drilling operation, the main expansion encountered intumescent expansion, windowing operations and cementing operations, the reasons for the analysis, put forward solutions and some improvements, for the next step similar to the operation mode provides experience .
