摘要： 控制烃类运移和聚集的根本因素是地下流体动力场,也就是地下流体势。恢复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。古流体势的恢复可归结为古孔隙度、古埋深及古地层压力的恢复,介绍了这三个参数的演化模型和恢复方法。渤南坳陷沙四段在东营组沉积末期和明化镇组沉积末期的流体势分布特征表明,渤南坳陷古近系的油气藏分布与古流体势演化有密切的联系,油气藏位于流体势较低的低能环境中。

Abstract: The underground dynamic fluid field, i.e. underground fluid potential, is an essential factor to control migration and accumulation of hydrocarbons. Reconstructions of paleo-fluid potential during each geological period following hydrocarbon generation may be helpful to proper recognition of petroleum reservoir distribution, which can be classified as ones of paleo-porosity, paleo-buried depth and paleo-pres-sure. This paper presents the evolution models and reconstruction methods for these three paleo-parameters, and makes analysis of paleo-fluid potential in Es4 during late Dongy ing and late Minghuazhen in Bonan depression. It is indicated that the Paleogene reservoir distribution is closely related to the paleo-fluid potential evolution and the oil-gas reservoirs could be found in low-energy env ironment of low paleo-fluid po-tehfi894-2017 China Academic Journal Electronic Publishing House.
