摘　　要：流体沿大断裂从深部向浅部运移的现象早已为地质学家所重视。随着研究的深入,认识到断裂活动与流体流动之间存在密切的时-空耦合关系,并且是地下流体压力(或流体势)、地应力和断裂活动性三者之间相互作用的结果,建立了一系列断裂与流体流动之间的动力学耦合模式。这些模式为研究断裂与油气关系提供了思路,对正确理解油气多次运移和多期成藏具有重要意义。It is early paid attention to by geologists that geofluids flow along large fault from deep to shallow due to the close relationships of faulting structure to minerals,hydrocarbons and earthquake.With the in-depth researches,it is recognized that there exist spatio-temporal coupled relationships between faulting and fluid flow,which is the result of the interaction among fluid pressure(fluid potential),ground stress and fault-ing activity.A series of coupled dynamic models on fault and fluid flow are developed that give us new thoughts for the study of the relationships between fault and hydrocarbon distribution,and have more impor-tance to correctly understand multistage migration and accumulation of hydrocarbon.
