摘　　要：广义的油气成藏动力学研究,泛指一切有关油气生、排、运、聚的机理性研究.文中所说的油气成藏动力学研究系统,是指在某一特定的地质单元内,在相应的烃源体和流体输导体系发育的格架下,通过对温度、压力(势)、应力、含烃流体等各种物理、化学场的综合定量研究,在古构造发育的背景上历史再现油气生、排、运、聚乃至成藏全过程的多学科综合研究体系,这实际上是含油气系统意义上的一种定量动力学研究体系.油气成藏动力学研究系统由模型研究与模拟研究两部分组成,在理论上集成了石油地质学的动力学研究成果,整个研究过程是在烃源体和流体输导体系的三维格架上进行的.这个研究系统有强大的计算机工作平台支持,模型研究与模拟研究结果的迭代反馈降低了地质解释中的多解性,是新一代的石油地质勘探研究工作系统.该系统在珠江口盆地的实际应用,表明了这一研究系统的具体应用效果.The general researches on pool_forming dynamics involves all mechanisms about hydrocarbon generation, expelling, migration and accumulation. The research system for pool_forming dynamics presented in this paper is a multidiscipline system in which hydrocarbon generation, expelling, migration and accumulation can be reconstructed within a development framework of source rock and fluid carrier against a paleo_tectonic background, by comprehensive researches of various physical and chemical fields such as temperature, pressure (potential), stress and hydrocarbon fluid. In fact, it is a quantitative methodology for pool_forming dynamics on the basis of petroleum system. The research system is composed of two parts, i.e. model and modeling, and has theoretically integrated dynamics research results in petroleum geology. The whole research process is conducted with the 3D framework of source rock and fluid carrier. As a new research system for petroleum exploration, it is supported by a powerful computer platform and the multiplicity in its geological interpretation can be decreased by iteration and back_feed of models and modeling results. The application of this system in Pearl River Mouth Basin has demonstrated its practical effect.
