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.

Key words: hydrocarbon migration, experimental modeling, numerical modeling, fluid potential, hydrocarbon migration, experimental modeling, numerical modeling, fluid potential

摘要： 油气二次运移是石油地质学研究的重要内容，同时也是个受多种因素制约、涉及多学科的复杂问题。近年来，人们从不同角度探讨了油气二次运移的机理，提出了多种研究油气二次运移的方法(除了地质方法外，还包括地球化学、物理、地球物理、实验模拟及数值模拟等方法)，特别是在油气二次运移的数值模拟方面取得了重要的进展。
