Numerical simulation analysis for migration-accumulation of oil and water

Numerical simulation of oil migration and accumulation is to describe the h istory of oil migration and accumulation in basin evolution. It is of great value in the exploration oil resources and their rational evaluation. This paper, puts forward the mathematical model and the modified method of alte rnating-direction implicit interactive scheme. For the famous hydraulic exp eriment of secondary migration-accumulation (cut plane and plane problem), it has been done the numerical simulation test, and both the computational and experimental results are identical.
