摘要
动态再现油气运移聚集过程的难点在于运移聚集模型的建立.传统的基于达西定律的油气运聚模拟有其局限性,而采用流线模拟模型,基于浮力驱动,跟踪计算油气运移轨迹流线,并将关于油气运聚的一些公认的地质模型转化成定量化的数学模型,体现在模拟中,实现了油气在非均匀介质中的充注动态过程模拟.基于此模拟结果,可进行区带资源评价,同时为地质家解释油气运移主通道提供一个可视化的直观的分析工具.实际模拟计算表明,该定量化模型合理可靠,能够满足实际地质分析需要.
The process of reconstructing the migration and accumulation of hydrocarbon depends on the establishment of an effective dynamic model. There are limitations using the traditional method to simulate hydrocarbon migration and accumulation based on Darcy＇s Law. This paper adopts the flow path model, based on the buoyancy-drive, follows and calculates the trace of streamline of oil and gas. Generally acknowledged geological models of hydrocarbon movement and accumulation are here represented by new quantitative mathematical models. The dynamic filling process of hydrocarbon in a nor-homogeneous layer was then simulated using these models. Based on the results of this modeling, the resources of oil and gas of plays can be evaluated, and a visible and intuitive analysis tool is provided for geologists to explain the main channel of hydrocarbon migration.
