为了解决钻修机能力有限、海上丛式井槽口限制导致水平井靶前欠位移以及下部轨迹因地质资料不足需要频繁调整等技术问题，通过对C33H井井身结构优化、合理轨迹设计、优选钻具组合和钻井参数，以及对Power Drive X5推靠式旋转导向工具侧钻能力分析、侧钻点的优选、精细要求侧钻操作，实现了使用Power Drive X5工具进行欠位移裸眼悬空侧钻作业，避免了由于地质因素不确定性造成的损失，节约了成本，为渤海油田后续类似作业积累了经验。

Due to the technical problems such as the limited capacity of drilling and work-over rig and limit of offshore cluster well rabbet, which may cause easily pre-target under-displacement and frequent adjustment of lower track caused by insufifcient geological data, for C33H well located in Liaodong Bay, the well structure is optimized, the well bore trajectory is reasonably designed and BHA and drilling parameters are selected carefully in the process of drilling. At the same time, by drilling capacity analysis of Power Drive X5 push-the-bit rotary steerable tool, optimization of sidetrack point, ifne requirements for sidetrack operation, Power Drive X5 tool is used for drilling in the vacant side of the hole, avoiding the loss due to uncertainty of geological factors and saving the cost of drilling, to accumulate technical experience for the follow-up similar job in the Bohai Oilifeld.
