摘　　要：总结油气藏发现的历史及油气藏分类方法发现，经典油气藏概念是定义构造油藏的充分必要条件，缺少定义复杂油藏和岩性油气藏的充分条件。因此，采用油气藏的聚集原理对岩性油气藏研究中的理论问题进行了探讨，认为油气成藏的构造因素是浮力因素，岩性因素是储层孑L隙结构因素；油气藏的形成过程是圈闭储集层中含油饱和度不断增加的过程；任何岩性油气藏的形成都不同程度地受到构造因素的影响，油气藏基本是随着构造的定型而定型。Through the summary of discover history and classification methods of hydrocarbon reservoirs, it is found that the classic concept of hydrocarbon reservoirs is the necessary and sufficient condition to define the structural reservoirs, but it lacks the sufficient condition to define the complex and lithologic reservoirs. Therefore, this paper discusses the theoretical problems about the study of lithologic reservoirs through the application of hydrocarbon reservoir accumulation principle. It is considered that the structural factor of reservoir-forming is the buoyancy factor. The lithology factor is the one that influences reservoir pore structures. The forming process of hydrocarbon reservoirs is a continuous process of oil saturation increase in the volumetric reservoirs. The formation of any lithologic reservoirs is influenced by the structural factors to different extent. Hydrocarbon reservoirs are basically decided by the final formation of structures.
