| 摘 要： | 川西海相区域在中古生代位于上扬子地台西缘台-槽过渡带,经历了基底形成阶段、地台及其周缘盆地形成演化阶段、前陆盆地形成演化盆山耦合三大演化阶段。"槽盆"或"台盆"形成演化控制烃源坳陷形成及演化,孕育多套烃源岩。印支晚期构造运动是川西构造发展中一个重要的转折,改变了晚三叠世以前扬子西缘川西克拉通及其周缘盆地演化的构造格局,调整了印支晚期前的川西海相油气系统。燕山-喜马拉雅多期次构造运动龙门造山带的强烈抬升挤压,使该区海相油气系统遭到破坏,部分可能被调整改造,在新的成藏背景下调整成藏;龙门山推覆带下存在的中古生界"原地体",保存条件好,其中有可能形成大中型的天然气藏。川西海相中古生界天然气基础地质条件优越,是有利的天然气勘探远景地区。

| Abstract: | The marine facies area in the western of Sichuan was located on the western margin of the upper section of Yangtze Platform in Paleozoic Era,which was the transitional zone of platform-trough environment.It underwent the basement-forming phase,platform and its marginal basin evolution phase,and foreland basin evolution phase.The evolution of trough basin or platform basin controlled the evolution of depression basin and formed multi-suite source rocks.The late period of the Indosinian movement was an import... |
