| 摘 要： | 在前中生代，形成了华北、扬子和塔里木等较大的海相及海陆交互相含油气区（盆地），构造格架呈南北分异。经海西-印支运动，形成统一的中国大陆板块，且整体构造格架演变为东西分异。根据盆地结构、构造变形样式、岩浆活动、地温场、壳幔结构及壳幔连通程度等方面的特征，论述了中、新生代中国含油气区的大地构造环境性质与含油气特征。据此划分出 4个具有不同构造环境性质的含油气区：①东部裂谷伸展区，其西带为华夏裂谷系，以产下第三系和白垩系原油为主，东带为大陆架裂谷系，以产下第三系煤型气为主；②中部克拉通构造稳定区，以产古生界天然气为主；③西北构造反转区，含油气层系较多，油气成因类型也多样；④特提斯碰撞-走滑区，构造变形复杂，部分地区具有较好的油气资源前景。进一步讨论了油气形成的"构造环境专属性"问题。

| Abstract: | Huge oil gas bearing areas with marine and paralic facies, such as North China, Yangtze and Tarim landmass(basin), had been formed in China during pre Mesozoic and the tectonic framework presented north south differentiation The united continental plate of China was formed by Hercynian Indonesian movements and its tectonic framework evolved to east west differentiation Based on the features of tectonics, style of structural deformation, magma activity, geothermal field, crust mantle structure and so on, the tectonic environment properties and oil gas bearing characteristics of Mesozoic and Cenozoic Chinese oil gas bearing areas (basins) are systematically discussed in this paper There are four kinds of oil gas bearing area, different in tectonic environment, have been formed since the Indonesian movement (1) The extensional region of rift in east China, it can be divided into two subtectonic regions The Cathaysian rift system in the west, in which the Eogene and Cretaceous crude oil is mainly produced The continental shelf rift system in the east, in which the most important gas source strata are the Tertiary coal deposits (2) The tectonically stable craton region in central China, in which the Palaeozoic gas is chiefly formed (3) The region of tectonic inversion in northwestern China, where there are different types of source layer systems and oil/gas (4) The collided slipped region of Tethys, it has complicated structural deformation and potential for oil gas exploration in part of the region The author has also put forward the idea of oil gas forming specialization of tectonic environment |
