中国含油气盆地与石油地质理论进展

What's New in the Oil-and-Gas-Bearing Basin aud Oil Geology Theory of China

中国沉积盆地受3个古陆块（中朝、塔里木和扬子）的离散、聚合和周边古板块作用演化的控制。整体上可划分为震旦纪—古生代海相盆地体系和中、新生代陆相盆地体系，前者具有天然气资源优势，后者具有石油资源优势。陆相石油地质理论已成为石油地质理论的重要组成部分，陆相成因油藏是中国石油开采的主体，理论和勘探的发展都在深入。古克拉通海相盆地近期在理论和勘探发现气田方面取得了明显的进展，天然气发展将会加速。

The sedimentary basins of China are controlled by three ancient continent plates (Korean China,Tarim and Yangtzs plates)of dispersed, polyreation and action and evolution of the circumferent ancientcontinent plates. As a whole, it can be devided into Sinian Period-Palaeozoicera marine facies system and MesozoicEra,Cenozoic Era continent facies system. The former has advantage in natural gas resource, and the later in oilresource. The continent oil geology theory has become an important part of the oil geology theory The continentalorigine reservoir is the chief part of the oil production in China. The development of the theory and explorationare both being deepened. The palaecraton marine basin has made an obvious progress in theory, exploration anddiscovering oiLgas fields recently. The development of natural gas will be quickened.
