The accumulation and distribution of marine gas hydrate is obviously heterogeneous. Using the theory and method of “hydrate petroleum system”, we chose typical international hydrate occurrence area, such as Gulf of Mexico, Blake Plateau, Hydrate Ridge and Nankai Trough, to describe the hydrate distribution characteristic in detail, and analyze the accumulation control factors of hydrate from stable condition, gas composition and source, fluid migration and sediment condition of these areas. Through analysis and comparison of the typical case studies, the control actions of various factors on hydrate heterogeneous distribution were summarized systematically, and “gas hydrate migration and accumulation system” was proposed. The result indicates that the area of hydrate occurrence is relatively small, seafloor temperature and pressure are uniform, both thermogenic methane and biogenic methane can be the source gas, and the gas composition in the areas is similar. Therefore, the migration condition providing pathway for gas-bearing fluid move and the favorable sediment body providing potential space for hydrate accumulation are the key control factors of hydrate distribution. The theory of “hydrate migration and accumulation system” was applied to Shenhu area in northern continental slope of the South China Sea, the fluid migration condition and favorable sediment body were researched, and the hydrate migration and accumulation system in Shenhu area was discussed preliminarily. This study suggests that the analysis of fluid migration pathways and the sedimentological interpretation of hydrate reservoir are the important direction for hydrate exploration in northern continental slope of the South China Sea in the future.
