| 摘 要： | 川西坳陷上侏罗统蓬莱镇组为前陆盆地上红层碎屑岩建造。笔者应用成因地层学原理和层序地层学研究方法，对川西地区蓬莱镇组开展露头层序，测井层序及地震层序的综合研究，划分出区域上可供对比的５个构造－充填层序（Ｓ１－Ｓ５０，并对每个层序的层序界面，沉积体系和岩相古地理展布与演化特征进行了讨论，为查明蓬莱镇组沉积相的时空配置关系，正确建立区域地层格架，开展有利储集相带的预测奠定基础。

| Abstract: | Penlaizhen Formation of Upper Jurassic in Western Sichuan Foreland basin consists of a set of red clastic sedimentary rock. The theroy and the methods of sequence and genetic stratigraphy are applied to study systematically the outcrop sequence, bore log sequence and seismic sequence developed in the formation and divide it into five tectonic filling sequence. The sequence boundary, sedimentary system and lithofacies paleogeography of every sequence are detailly described and these five tectonic filling sequences are related to the sedimentary response of the five tectonic activity of Longmenshan orogenic belt.The study lays the foundation of determination of relation of time space distribution of sedimentary facies, construction of regional sedimentary patterm and prediction of favourable reservior facies belt. |
