Abstract: Hydrocarbon migration is a very important research aspect in petroleum geology and exploration. It is also a complicated problem influenced by lots of controlling factors and involves many scientific and engineering aspects. Development of hydrocarbon migration researches in China is summarized. A variety of methods such as geological, geochemical, physical, geophysical, experimental modeling, and numerical modeling areused to study the mechanisms of hydrocarbon migration in recent years. Particularly, numerical modeling has drawn extensive attention in researches. Some scholars consider other new factors which effect hydrocarbon migration, e.g. ground stress, channel and block on the pathway, phase-state of fluids, etc. Three-dimensional numerical models are developed by many researchers, including some new modeling methods such as artificial neural net work simulation, alternating-direction implicit interactive scheme, and second order splitting-up implicit interactive scheme. The authors also point out the development trends in the future.
