我国石油物探技术前景展望

伴随着我国大部分油田进入到开发的后期阶段，在需要提高油气采收率和钻井工作效率的同时，石油物探技术也变得越来越重要。提出了传统物探方法所面临的问题，并介绍了目前国内外应用广泛的物探相关技术，主要有叠前深度偏移技术、四维地震技术、多波多分量地震勘探技术和井间地震技术，详细分析了传统物探理论的弊端，并对比分析了井间地震、多波多分量和四维地震3种理论本质上的异同，探讨了叠前深度偏移技术的求解过程，介绍了各项技术工作原理及应用状况，并从2个方面对我国物探理论技术的发展前景进行了展望和预测。

Prospects of petroleum geophysical technology in China

With the majority of our field going into the late development，it′s time to enhance oil recovery and drilling efficiency and as the same time the oil prospecting technology has become increasingly important.In this paper，the problems of traditional geophysical methods have been put forward，and the geophysical techniques used at home and abroad widely were introduced，including multi-wave and multi-component seismic exploration technology，well seismic technology，four-dimensional seismic technology，pre-stack depth migration.In this paper，the disadvantages of the traditional geophysical theory were analyzed in detail，and the similarities and differences of the three theories of interwell seismic，multi-wave multi-component and four-dimensional seismic were discussed.The solution process of prestack depth migration，and from two aspects to prospect and forecast development prospect of geophysical prospecting theory and technology in China.
