| 摘要: |
| 川西坳陷有着复杂的形成与演化历史,从而导致油气成藏、圈闭类型复杂的局面。通过对川西主要气藏圈闭分析,把圈闭成因作为分类的基础,圈闭形态及遮挡方式作为划分各大类中次一级亚类的依据。按形成油气圈闭的主导成因差异,将川西坳陷圈闭划分为构造圈闭、地层圈闭和成岩圈闭三大类型。其中,岩性圈闭和古构造-成岩圈闭是川西坳陷的优势圈闭。 |

| Abstract: |
| The traps in western Sichuan depression may be grouped, on the basis of their genesis, into structural traps, stratigraphic traps, and diagenetic traps, in which the lithologic traps and paleostructural-diagenetic traps are believed to be the dominant traps in the depression. |
| Key words: western Sichuan depression gas pool trap classification |
