四川盆地东南缘清虚洞组层序-岩相古地理特征及其油气地质意义
Characteristics of sequence-based lithofacies and paleogeography of Qingxudong Formation on the southeast margin of Sichuan Basin,China
摘要
Abstract
Qingxudong Formation.During the development of HST in sq2,the sedimentary pattern is evolved into the tidal flat environment of the restricted platform.In sq3 parasequence set,only HST sedimentary records have remained,belonging to the frequently exposed tidal flat environments. There,the gypsum rocks have most developed.sq3 parasequence set is one of the most important sets of the dense cap rock for the gas reservoirs of Dengying Formation and Qingxudong Formation.关键词
