构成油藏的岩石是不均质的,孔隙结构十分复杂,在油藏开发过程中,油藏内发生的往往是多组分、多相流体的三维流动,为了认识流体在油藏内的流动规律,常使用岩心实验、井下电视、井下测试及开辟生产试验区等多种直接观测方法来进行油藏研究。随着科学技术的发展,油藏模拟技术在油田开发中得到了广泛的应用。 The rocks that constitute the reservoir are heterogeneous and the pore structure is very complicated. During the process of reservoir development, the three-dimensional flow of multi-component and multi-phase fluids often occurs in the reservoir. In order to know the fluid flow in the reservoir Regularly, many direct observation methods such as core experiment, downhole TV, downhole test and development of production test area are used to carry out reservoir research. With the development of science and technology, reservoir simulation technology has been widely used in oilfield development.
