在印尼Caltex Pacific的Sumatra岛Duri油田正在进行着四维勘探,或叫三维时移地震勘探。地震技术正在大量地提高原油采收率,使世界最大蒸汽驱油田的能源利用最佳化。在北海的Ekofisk油田,菲力普石油公司已将井中地震成像(也叫垂直地震剖面)与三维和四维的地表地震资料结合起来监测油藏,并更有信心地确定新的井位来恢复生产。在堪萨斯西南部的Kinsler油田,阿莫克、德士古和大陆石油公司已借助井间地震成像制定钻井决策和进行油藏表征。这些成果标志着地震技术除用于勘探之外,又向前有了很大的发展,成了油田开发和生产的重要工具。同时这些例子也表明,工程技术人员和地学工作者若真正地遵行多学科组织协作就有可能将未利用的资源转为可采储量。
The Duri field on Sumatra Island, Caltex Pacific, Indonesia, is undergoing four-dimensional exploration or three-dimensional time-shifted seismic exploration. Seismic technologies are dramatically increasing oil recovery and optimizing the energy use of the world’s largest steam flooding field. At Ekofisk in the North Sea, Phillip Petroleum has combined well bore seismic imaging (also known as vertical seismic profiling) with 3D and 4D surface seismic data to monitor reservoirs and confirm new wells more confidence to resume production . In the Kinsler field in southwestern Kansas City, Amoco, Texaco and Continental Oil have made drilling decisions and reservoir characterization with crosswell seismic imaging. These achievements indicate that besides the exploration, the seismic technology has made great progress and has become an important tool for oilfield development and production. At the same time, these examples show that if engineers and geoscientists really follow the multidisciplinary collaborations, it is possible to turn unutilized resources into recoverable reserves.
