油气藏分类研究的讨论

油气藏形成和分类研究是石油地质研究中最引人入胜的部分,油气分布规律的核心是油气藏分布规律,油气勘探的成效,是基于对油气藏形成分布规律的认识。油气藏分类是认识油气藏形成特征、研究油气藏分布规律的重要方法。

DISCUSSION ON THE CLASSIFICATION OF HYDROCARBON POOLS

The classification of hydrocarbon pools is an important approach to understand the formation characters and study the distribution regularities of the pools.Since single-factor classification can not explain the basic properties completely,the author suggests that a comprehensive classification should be adopted.Thatis to say,to term the pools according to the types of oil-controlling factors,trap forms,the origins and to subterm the pools in accordance of the textures of reservoir rocks and the states of hydrocarbon.Based on this pririciple,hydrocarbon pools can be divided into fold type,fault type,lithologic type,boundary belt type and further divided into 32 subtypes.Hydrocarbon pools of boundary belt type are further explained by the author.
