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.
