拉张槽对四川盆地海相油气分布的控制作用
Control of intracratonic sags on the hydrocarbon accumulations in the marine strata across the Sichuan Basin,China
摘要
Abstract
formed extensional structures,such as Kaijiang-Liangping and Mianyang-Changning intracratonic sags etc ..The Kaijiang-Liangping sag occurred during late Permian to early Triassic,characterized by NW-SE striking deposits of deep-water carbonate facies.The discovery of Kaijiang-Liangping sag is based on the theory of the Emeishan taphrogenesis and the organic reefs exploration in the basin.The Mianyang-Changning sag occurred during early Cambrian period, dominated with N-S striking deposits of abundant Lower Cambrian clastic rocks.The discovery of the early Cambrian intracratonic sag is based on the theory of the Xinkai taphrogenesis and the sedimentary-tectonic comprehensive study.The intracratonic sags have significant influence on the oil and gas occurrences along the margin of the sags in the interior of the Sichuan basin,chiefly through its influence on the distribution of high-quality carbonate reservoir rocks and mudstone source-rocks.In particular,the intracratonic sags provide favorable conditions for the formation of assemblage of high-quality carbonate reservoir rock and mudstone source-rock and raise the efficiency and scale of the hydrocarbon accumulations. Therefore,the margin areas of the intracratonic sags are the most favorable areas of the hydrocarbon accumulations in the marine strata of the Sichuan Basin.关键词
