【摘要】 油藏动态监测的主要目的是:通过对油藏开采过程的动态监测,建立定量、精细、动态的油藏模型,并通过油藏数值模拟预测油藏开发的性能,优化开发方案,提高油气采收率。时延地震已经成为油藏动态监测的一种成熟和有效工具,并且已经在油气开发过程中得到了一定的应用。分析了油气藏动态监测的地球物理基础,从时延地震可行性分析、数据采集、数据处理、属性分析、综合解释和应用等多方面,介绍了技术的发展现状,最后对时延地震技术发展的特点和趋势进行了分析和展望。更多还原

【Abstract】 The main goal of dynamic reservoir monitoring is to establish a quantitative, detailed and dynamic reservoir model via dynamically monitoring the development of the reservoir, to predict the development behavior of the reservoir via reservoir numerical simulation, and ultimately to optimize development scheme and enhance oil recovery. Time-lapse seismic has developed into a mature and effective tool for dynamic reservoir monitoring and has been applied in the course of oil & gas development. This paper discusses the geophysical fundamentals of dynamic reservoir monitoring from aspects of time-lapse seismic such as feasibility analysis, data acquisition, data processing, attribute analysis, integrated interpretation, and applications,describes the status of time-lapse seismic technological development,and presents an outlook for time-lapse seismic technological growth.更多还原
