| 摘 要： | 对塔里木盆地东部地层压力结构和天然气性质差异的研究表明，塔里木盆地东部具有多个独立的天然气运聚系统。这些运聚系统具有流体封存箱的特征。天然气只能在运聚系统内部进行短距离的运移，不能进行大规模侧向运移。因此天然气藏的形成具有近源的特点。由于不同运聚系统特征的差异，塔里木盆地大致有三种天然气运聚模式。

| Abstract: | Bsaed on the studies of structures of formation pressure and the characteristics of natural gas in Tarim Basin,the paperl shows that there are several independent natural gas migration and accumulation systems in the eastern part of Tarim Basin. There are no hydrodynamic connections between the systems and the characteristics of natural gas is different in different systems. The migration of natural gas was restricted within the limit of individual system,and the lateral migration across the systems was very difficult. As a result,the natural gas generated in a system could only accumUlate within the same system,and this is very important to the occurrence and evaluation of natural gas in the basin. According to different geological conditions in different systems,three kinds of migration and accumulation models have been developped. |
