| 摘 要： | 作为流体矿藏气藏与油藏的形成和分布具有相似性，都需要经过由分散到富集的成藏过程。天然气来源的广泛性和易于溶解、运移、散失的特性，决定了天然气双石油具有更多的运聚成藏方式和时空分布的广泛性。水溶对流运移、多源复合成藏、溶解气脱溶成藏、运聚动平衡成藏，是天然气运聚成藏的重要特点。

| Abstract: | This paper has mainly discussed the similarities and differences between oil pools and gas pools in the respects of hydrocarbon sources,reservoir properties,migration and accumulation mechanisms,and preserving conditions.As mineral deposits,both oil and natural gas pools have similar conditions for the formation and preservation;they need hydrocarbons concentrations by migration and relative stable preserving conditions,etc.Compared with oil pools,gas pools have many particular properties,such as multiple gas sources,combination of varity of gases,lower standard of reservoirs and higher standard of cap rocks,etc.Because natural gas can easily migrate and has many states of migration,there are many formation mechanisms for the gas pools;convection migration of gas and the separation of dissolved gas may be an important migration and formation mechanism for the gas pools. |
