摘要: 依据露头层序地层学的基本原理和基本工作方法及思路,对上扬子地区寒武系进行层序划分与对比,并在早寒武世三级层序内探讨沉积相平面展布与空间分布。早寒武世扬子地台被动大陆边缘一侧持续发生海侵,沉积体系域以海侵体系域TST和高位体系域HST为主,缺乏低位体系域LST。分别编制海侵期和高位期两幅不同时期的沉积模式图表现三级层序的沉积体系特征,并对目的层段牛蹄塘组黑色页岩作出评价,从而揭示出露头层序地层学在页岩气初期勘探中的重要应用价值。

Abstract: In this article, with the basic principle and method of sequence stratigraphy, the discrimination and contrast of Cambrian sequence in the Upper Yangtze region were made, and the plane and spatial distribution of sedimentary facies were studied within three-order sequences in Early Cambrian. During Early Cambrian, transgression happened continuously on the passive continental marginal side of Yangtze platform, so the systems tracts mainly included TST and HST, missing LST. Therefore, two sedimentation models of two stages, i.e. transgression stage and high stand stage were identified, which revealed the sedimentary characteristics of Cambrian sequence. Taking the black shale of Niutitang Formation in Lower Cambrian as an example, the shale reservoir was evaluated, and the result indicated that the sequence stratigraphy of outcrops was evaluable in the initial exploration of shale gas.

Key words: outcrop sequence stratigraphy, three-order sequence, distribution of sedimentary facies, exploration of shale gas
