摘　　要：四川盆地是特提斯构造域巨型油气富集带中一个大型古生代—中新生代海相—陆相叠合盆地,其形成与演化受特提斯构造域与滨太平洋构造域控制。研究表明四川盆地的形成演化曾经历了中—晚元古代扬子地台基底形成阶段;震旦纪—中三叠世被动大陆边缘阶段;晚三叠世盆山转换与前陆盆地形成演化阶段;侏罗纪—第四纪前陆盆地沉积构造演化阶段。盆地内古生代—中生代广泛发育良好的烃源岩,而且形成多套生储盖组合,发育大型构造圈闭,储集层、盖层及保存条件相对较好,具有再次发现大中型油气田的条件。The Sichuan Basin, a large Paleozoic and Meso-cenozoic era marine and continental basin, is situated between Tethys tectonic domain and marginal Pacific tectonic domain, which control its formation and development. It has undergone a complicated development process divided into four stages as follows: the crystal basement of Yangtze platform form stage since Meso-Proterozonic-Neo-Proterozonic; ②passive continental margin-cabonate rock platform stage since Sinian and Middle Triassic period; ③foreland basin development and sediment in Upper Triassic; ④foreland sediment and tectonic evolution since Jurassic-Quaternary. Source rock in the Basin developed very well in the period between Meso-Paleozoic and Mesozoic, where many sets of 'source-reservoir-cap' assemblage had been formed. The Sichuan Basin, with the developed traps, matured source rocks with good preserving abilities, has provided good conditions for discovering middle and large gas fields.
