摘要： 四川盆地涪陵海相页岩气区具有不同于北美页岩气区的地质条件，很难直接采用北美大规模、高密度、连片化布井的开发模式。针对四川盆地涪陵页岩气田下部气层一次井网开发后剩余资源精细刻画难度大、剩余资源动用率低和提高老井最终技术可采储量（EUR）技术不完善等难题，提出了适用于涪陵海相页岩气立体开发特点的地质工程一体化思路。在页岩气立体开发方案实施过程中，对剩余气分布、钻完井、压裂和生产等多学科知识进行系统总结，建立地模数模一体化储量动用评价技术、立体开发调整井位一体化优化技术和钻井、完井配套工艺一体化实施技术，形成了一套地质工程一体化技术系列，有效指导了涪陵海相页岩气高效立体勘探开发。

Abstract: The geological conditions of Fuling marine shale gas in Sichuan Basin are different from that in North America. Therefore, the development mode of large-scale, high-density and continuous well drilling applied in North America is not applicable to Fuling shale gas field. In view of the difficulties of fine characterization of the remaining resources after the primary well pattern development of the lower gas layer, low production rate of remaining resources and imperfect technology to improve the ultimate technically recoverable reserves (EUR) of old wells, the idea of geology and engineering integration is proposed suitable for stereoscopic development of Fuling marine shale gas. During the implementation of shale gas development, the multi-disciplinary knowledge such as remaining gas distribution, drilling and completion,fracturing and production has systematically been summarized, and a set of geology and engineering integrated technology series been formed, including geology modeling and numerical simulation integrated reserve production evaluation technology, integrated stereoscopic development and well adjustment optimization technology, integrated drilling and completion supporting engineering technology, which has effectively guided the high-efficiency stereoscopic exploration and development of Fuling marine shale gas.
