新海27-H58井位于海外河油田新海27区块内,是利用水平井对海11-36井区进行二次开发的生产水平井。在分析该井在钻井施工中的难点的基础上,优化井身结构,控制井身轨迹,提出合理论证,针对该区块地层不同特点制定相应措施,对固井作业提出严格策略;实钻证明,精细策略钻井是完全可行的。该井的成功实施为今后新海27块后续水平井的钻井施工提供借鉴。
The Xinhai 27-H58 well is located in the Xinhai 27 block of the Overseas Hetian Oilfield. It is a production horizontal well for secondary development of the Hai-11-36 well using horizontal wells. On the basis of analyzing the difficulty of the well during drilling, the well structure is optimized, the wellbore trajectory is controlled, reasonable justification is given, corresponding measures are formulated according to different characteristics of the formation, and stringent strategy is proposed for cementing operation. , Fine strategy drilling is entirely feasible. The successful implementation of the well provides reference for future drilling of 27 horizontal wells in Xinhai.
