Dynamic Types and Geol ogical Conditions of Gas-Bearing Basins in China

摘要: 以板块构造理论为指导，遵循盆地构造动力学类型分析的理想模式和地质实际相结合的原则，将我国主要含气盆地划分为6类9型15种，并系统分析了各类盆地的天然气地质条件。认为在中国东部边缘海裂谷盆地具有形成大中型气田的优越地质条件，陆内裂谷盆地可寻找由中小型气田连片而成的大中型气区；在中国西部，寻找大中型气田的重要领域是克拉通转化盆地。Abstract: On the basis of the theory of plate tectonics, according to the organic relationship between the successful model of basi:xai dynamic types and the geological conditions,main gas-bearing basins in China are classified into six groups and nine sub-groups comprising fifteen kinds by which the gas-bearing geological factors of all kinds of basins are studied, which show that in the east of China marginal sea have advantage geological conditions becoming middle or even big gas fields and intracontinental rift basins may find many small and middle gas fields some of which are possibly combined with each other so that they can form middle or big gas fields,that the important zones of middle or big gas fields in the west of China are craton transformed basins.
