Abstract:

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.
