| 摘 要： | 简介了天然气运聚动平衡原理及天然气运聚动平衡模型，据此研究了川西平落坝的构造两类不同成因的气藏：（１）对于储层与烃源岩相间的气藏，在地史中若天然气补充量大于其散失量则成藏，如上三叠统香四段、香二段气藏；反之则不能成藏，如上三叠统须二段（２）对于中侏罗统沙溪高组次生气藏，下伏气源岩所生成天然气向上扩散的速度和气量均大于该气藏本身透过盖层而散失的，故能成藏。

| Abstract: | ??Based on the dynamic equilibrium principle and it's model of natural gas migration and accumulation,two kinds of gas reservoirs with different genesis in Pingluoba structure are studied:??for the gas reservoirs lie between the reservoir and hydrocarbon source rock,if the volume of charging gas is larger than that of the lost,the gas reservoir can form,such as the gas reservoirs in Xiang 4 member and Xiang 2 member of Upper Triassic;otherwise the gas reservoirs can't form,such as gas reservoirs in Xu 2 member of Upper Triassic;??for the secondary gas reservoirs in the Lower Jurassic Jurassic J1s,if the speed and volume of gas diffused up from underlying source rock is larger than that of gas loss through the cover formation,the gas reservoirs can form too. |
