大地构造研究在我国东部油气勘查中的应用

APPLICATION OF TECTONIC STUDIES IN HYDROCARBON EXPLORATIONS IN EAST CHINA

中国含油气区大地构造研究,从槽台观点到板块构造基础理论,应用到东部地区着重研究了陆缘地壳和上地幔岩石圈层结构、运动和发展规律。阐明自印支期以来新全球构造阶段地壳深部活动机制,有效地解释了中新生代裂谷,裂陷盆地的起源和演化,以及构造对油气的生成、运移、聚集、保存直至成藏的控制作用,为油气勘查从陆地到海域发现大批油气田做出了积极贡献。

Studies on tectonisms in oil/gas-bearing regions in China, ranging from views on geosyncline and platform theory to those on the theory of Plate Tectonism, were applied to researches on the textures, movements and evolutions of the lithosphere, which consists of the crust and the upper mantle. The mechanism of deep crustal movements in neo-global stage (since Indosin-ian Period) was clarified, and the impact of origins and evolution of Meso-zoic to Cenozoic rift basins and depressions, and structures on the generation, transportation, accumulation, preservation and mineralization of hydrocarbon resources were also studied. These studies contributed a lot to the discoveries of numerous oil/gas fields, both onshore and offshore.
