油气成藏动力学模拟现状与展望

THE DEVELOPMENT AND PROSPECT IN THE SIMULATION OF PETROLEUM POOL-FORMING DYNAMICS

油气成藏是包括油气生成、运移、聚集以及保存和破坏各个环节在内的复杂过程,受多种地质因素控制,与生烃中心、古今构造、生储盖组合、沉积相带、储层岩性等要素的演化均有关系。成藏动力学系统是含油气系统理论的新发展,是一门刚刚起步的新学科。油气成藏动力学研究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的重要技术支撑系统。该文介绍了油气成藏动力学的产生与技术背景、原理模拟系统。最后对成藏动力学的发展提出展望。

Petroleum pool-forming is complicated processes that includes generating, transportation, accumulation, storage and breaking of petroleum. It is under the control of many geological factors, thus that has relation with center of hydrocarbon-generating, ancient-modern structure, petroleum bearing assemblage, belt of sedimentary facies, property of reservoir rock and its variation. The system of petroleum pool-forming dynamics is the new development of theory of petroleum system and new underway subject. The study of petroleum pool-forming dynamics is based on the support of computer workstation, alternative feedback in study of model and result of simulation reduces fuzzy property of geological interpretation. Thus it is the new supporting system of main technology in geological survey of petroleum. This paper has introduced the development, technological background, principle and simulation system of petroleum poolforming dynamics. Lastly the prospect for the progress of petroleum accumulation dynamics is put forward.
