摘　　要：控制烃类运移和聚集的根本因素是地下流体动力场,即地下流体势.恢复自烃类形成以来的各个地史时期的古流体势,有助于正确认识油气藏的分布规律.古流体势恢复可以归结为古孔隙度、古埋深及古地层压力的恢复.东营凹陷通王断裂带沙二段和沙三中段在东营末期和明化镇末期的流体势分布特征分析表明,东营凹陷南斜坡下第三系油气藏的分布与古流体势的演化有密切的联系,但是不同类型的油气藏与古流体势演化的关系又不完全一样.The underground dynamic fluid field, i.e. fluid potential, is a fundamental factor to control migration and accumulation of hydrocarbon. Reconstructions of Palaeo-_fluid potential during each geological period after hydrocarbon generation may be helpful to accurate recognization of hydrocarbon reservoir distribution. The reconstruction of palaeo-_fluid potential can be composed of palaeo-_porosity reconstruction, palaeo-_depth reconstruction and palaeo-_pressure reconstruction. For Tongwang fault belt in Dongying sag, the analyses of palaeo-_fluid potential in Member Es 2 and middle Member Es 3 during latest Dongying and latest Minghuazhen have indicated that the Paleogene reservoir distribution on the south slope of Dongying sag is closely related to the palaeo-_fluid potential evolution, although each type of reservoir has a distinct relationship to this evolution.
