摘要: 本文从场的基本概念出发,简述了地球化学场的特征,着重论述了成烃过程中地球化学场的演化及其特征,并探讨了其他地质场(地热场和应力场等)与有机地球化学场在成烃过程中的耦合作用。认为各种场的相互匹配是形成油气藏的关键因素。

Abstract: Base on the fundamental concept of the field theory,this paper states the characteristics of the geochemical field in brief,discusses emphatically the evolution and characteristics of the geochemical field during hydrocarbon formation,and probes into the coupling actions between the organic geochemical field and other geologic fields(such as the geothermal field,the stress field,etc.)during hydrocarbon formation.It is considered that the mutual matching of different fields is the key factor for the formation of petroleum accumulation.
