| 摘 要： | 根据"安县"运动产生的不整合及前陆盆地可容空间的变化特征,对存在多个地层划分分区的川西前陆盆地上三叠统须家河组煤系地层进行了岩性地层和层序地层的对比和划分.研究结果表明,前陆盆地内发育有两种层序模式,即构造层序和气候层序.构造层序又分为早期海相构造层序和晚期陆相构造层序两种类型,在川西前陆盆地东部和中部的须家河组煤系地层中可能发育地层油气藏.

| Abstract: | According to the unconformable contact resulted from "Anxian" tectonic movement and the changeable accommodation of foreland basin,the lithological and sequences strata of Xujiahe Formation of the Upper Triassic in Chuanxi foreland basin were classified and correlated.Two kinds of revolutionary models for sequences including structural sequence model and climate sequence model developed in foreland basin were presented.The structural sequence was departed into early marine structural sequence and late continental structural sequence.The east and middle parts of Chuanxi foreland basin were favorable to development of stratigraphic reservoirs. |

| Keywords: | Chuanxi area foreland basin sequence stratigraphic model structural sequence climate sequence stratigraphic reservoir |
