国外井震联合精细油藏表征技术进展

Foreign Technical Progress in Fine Reservoir Characterization Based on Well-to-seismic Integration

井震联合精细油藏表征技术是开发地震的一项重要技术,自20世纪90年代成为热门研究课题以来,在国外已经得到广泛的应用,并取得了较好的油田应用效果。该技术的主要特点就是以多学科、集成化为手段,以三维地震和四维地震为核心,进行综合地质建模,对油藏进行定量化表征,以挖掘剩余油,提高油田的最终采收率。该技术在北海奥塞贝格油田和哥伦比亚卡萨别油田获得成功应用,对于我国一些成熟油田的后期开发具有指导和借鉴意义。

Fine reservoir characterization with well-to-seismic integration is an important technology for development seismology. Since this technology became a hot research issue in 1990s, it has been applied widely abroad, and achieved great effect in oilfield application. This technology is characterized by multidisciplinary and integration, and is used to establish geological model by combining with 3D and 4D seismic data and make quantitative reservoir characterization in the hope of developing remaining oil and finally improving the ultimate recovery factor. The successful application of this technology in Oseberg Oilfield in North Sea and Casabe Oilfield in Columbian provides a great guidance for the latter development of mature oilfields in China.
