摘要
讨论了油气二次运移的驱动力和影响因素,对F.K.Lehner 1987年提出的浮力驱动游离相态的油气二次运移数学模型在辽东湾地区北部进行了探索性的应用研究,建立了LZ255地震主测线典型剖面的地质模型,提供了模拟所需的各种参数的选取过程,并利用有限元法实现了浮力驱动油气二次运移的数值模拟,对模拟结果及其存在的问题进行了讨论,定量模拟结果与我们直观的定性认识相吻合,并可通过图示追踪油气运聚的地史过程。
The driving forces and influence factors of secondary hydrocarbon migration are discussed. In 1987, F. K. Lehner constructed a mathematical model of secondary migration as a buoyancy-driven separate phase flow. According to the model, we established a typical geological cross action of two-dimensional secondary migration in Liaodong gulf. The studying and using are indicated in the paper. The results of buoyancy-driven secondary hydrocarbon migration are shown to behave as expected intuitively. The geological processes of development of hydrocarbon migration and accumulation patterns are traced by map view. The perceptual recognition of evolution of hydrocarbon migration and accumulation is deepened.
