摘要： 中国油气地质条件无论在生、储、盖方面,还是在运、聚、保方面都有自己的特点。如陆相生油、多期生油,多种多样的储集岩体,复杂的储集岩性,明显的生储盖组合,油气的再次运移和运移距离不长,复式油气聚集带,以及较强的有机质变质作用等。这些特点的形成,是由于构造运动的多旋回性和印支、燕山运动波及中国大陆,致使海水基本退净所致。这些特点在各含油气盆地中都有不同程度的反映。

Abstract: Petroleum geologic conditions in China have their own characteristics in the aspect of source,reservoir, caprock or migration, accumulation and preservation, for instance, oil generated from continental facies, multiple periods of oil generation, muliplicity of reservoir rocks, complex reservoir lithology, distinctive source-reservoir-caprock assemblage, relatively short-distance remigration of oil and gas, complex oil and gas accumulation belt, and relatively severe organic alteration. Those result from multicyclic tectonie movemnents and regression caused by Indosinian and Yanshan movement. They can be found to different extents in each petroliferous basin in China.
