环江油田长6油藏位于鄂尔多斯盆地西部,濒临西缘逆冲带,储层岩性致密,物性差,埋藏深,初期开发单井产量低,效益差,地质储量一直未动用,作者立足解决环江长6油藏效益开发难题,总结长6油藏开发经验及技术,逐步形成了井网部署、储层改造、注水方式、开发政策及水平井导向等开发配套技术,实现了环江长6油藏效益开发,盘活可采储量达5000万吨,为类似油藏的高效开发提供了理论依据。
The Chang 6 reservoir of the Huanjiang Oilfield is located in the western part of the Ordos Basin and is on the verge of a thrust belt in the western margin. The reservoirs are lithologically dense with poor physical properties and deep burial. The single well developed in the initial stage has low yield and poor efficiency, and the geological reserves have not been used for a long time. Huanjiang Chang 6 reservoir efficiency development problems, summed up the Chang 6 reservoir development experience and technology, and gradually formed a well pattern deployment, reservoir modification, water injection, development policies and horizontal well-oriented development and supporting technologies to achieve the Central River long 6 Benefit of reservoirs Development and activation of recoverable reserves of 50 million tons provide the theoretical basis for the efficient development of similar reservoirs.
