| 摘 要： | 四川盆地川西坳陷蕴藏有丰富的天然气资源，通过多年勘探、发现其成藏聚集规律复杂，利用天然气运移模拟研究能有效地降低钻井风险。通过适合川西坳陷地质特征的二维沉积史、地热史、生烃史的模拟，证实了川西坳陷存在两个烃高峰期（三叠纪末和侏罗纪末－白垩纪），模拟出相应于两个生烃高峰值时的古构造，明确了砂岩的致密化进程，采用动态运移模型使得天然气运移模拟更加精确，并提出几个有处勘探区。

| Abstract: | The western Sichuan depression is rich in natural gas.Previous exploration has proved that the formation of gas reservoir is complex.2D modelling of the burial sedimentary history,thermal history and hydrocarbon generation history reveals two peak periods of hydrocarbon generation,the Late Triassic and Late Jurassic Cretaceous.The psleostructure corresponding to the two peaks of hydrocarbon generation is simulated and the compcting process of sandatone is determined.The application of dynamic migration model is proved to be more accurate.Several favourable exploration area are proposed. |

| Keywords: | Sichuan basin west Sichuan depression migration and accumulation of natrual gas palaeostructure peak of hydrocarbon generation |
