含油气系统中流体输导体系的研究

On Fluid Conducting System in Petroleum System.

流体输导体系是含油气系统的一大基本要素。含油气系统强调油气从烃源岩到圈闭的过程是一个动态的过程，因此，在进行流体输导体系的研究时，必须考虑烃源岩、流体输导层、封闭层在时空上的配置关系，然后才能建立起流体输导体系的整体格架。论述了流体输导体系的研究流程，包括源岩分析、输导网络、流体势、异常压力以及流体示踪技术的研究等。并进一步强调了运用动态分析的方法来研究流体输导体系的必要性，给出了流体输导体系研究在莺－琼盆地中的实际应用。

Fluid conducting system is an essential element in petroleum system where the oil and gas is believed to be a dynamic process from forming hydrocarbon source rock to trapping petroleum. When making a study of fluid conducting system, we have to take account of the time-space relations among hydrocarbon source rock, fluid conducting stratum and seal before setting up the whole framework of fluid conducting system. This paper presents this system, in-cluding studies of source rock analysis, conducting network, fluid potential, abnormal pressure and fluid tracer tech-niques. Meanwhile, necessity of using behavior analysis method to study that system is highlighted. A case of application of that system in Yinggehai-Qingdongnan basin is also presented.
