| 摘 要： | Y3复杂断块油藏具有构造系统复杂、断块多、断层多、断块小、含油层位多、油藏类型多等特点，利用常规钻井技术开发难以有效提高经济效益。通过Y3区块已钻井实际资料的统计分析，针对井身结构、井眼轨道、钻头类型提出了适用于本区块钻井的钻井优化方案。现场应用结果表明，实钻轨迹与设计方案符合率达到90%，且无井下复杂情况发生，进一步说明了设计的钻井优化方案的技术可行性，也为后续井的跨断块开发及优快钻井施工提供了重要技术支撑。

| Abstract: | Y3 complex fault block reservoir is with characteristics of complicated tectonic system, many small fault-blocks, faults, many oil bearing formations and different oil reservoir types; it is difficult to improve economic benefit by traditional drilling techniques. Based on the statistical analysis on real drilling data of Y3 block, and according to the casing program, well trajectory and the bit type, the optimized drilling plan suitable to this block was put forward. The application shows that the coincidence rate between drilling trajectory and design plan is 90%, which further indicates the technical feasibility of optimized drilling plan, and provides the important technical support to subsequent well in the cross fault-block development and optimized & fast drilling construction. |
