现在地震技术的进展使从平面上和深度上获得关于油藏内的流体分布的可靠信息成为可能。这一信息能够帮助提供较好的决策并且模拟使生产最佳优，提高采收率和降低成本的各种选择。这些进展的总合是四维地震或时间推移三维地震测量。在过去的10年期间，已经发表了涉及不同地质和油藏条件的许多成功的地震油臧监测实例研究。本文介绍了四维地震的概念。四维地震的效益和使用；四维地震如何工作和四维地震资料分析。
Advances in seismic technology now make it possible to obtain reliable information both on the surface and in depth about the distribution of fluids within a reservoir. This information can help provide better decisions and simulate options that optimize production, improve oil recovery, and reduce costs. The sum of these advances is a four-dimensional seismic or time-lapse 3D seismic survey. During the past decade, many successful case studies of seismic monitoring of oil and gas have been published that address different geological and reservoir conditions. This article introduces the concept of 4D seismic. Benefits and uses of 4D earthquakes; how 4D earthquakes work and 4D seismic data analysis.
