摘要： 渗流场与应力场的耦合作用在油气二次运移过程中突出地表现为应力场影响渗流场。地应力是影响储层沉积水水头的主要因素,地应力梯度是油气水运移的主要驱动力。油气二次运移可分为两个阶段,即沉积物的自重应力梯度驱动阶段和构造应力与自重应力的叠加应力梯度驱动阶段。对两个阶段的古应力场进行量级反演是油气预测的一种新途径。

Abstract: The coupling of seepage and stress fields is represented by the effect of stress field on seepage field during oil and gas secondary migration. Terrestrial stress is a main control on hydrostatic head of reservoir, and its gradient powers oil, gas and water migration. Oil and gas secondary migration can be divided into two stages according to type of drive: drive by self-weight stress gradient and stacked stress gradient of tectonic, and self-weight stresses. Progressive inversion of palaeostress field at two stages is a new way for forecasting oil and gas reservoir.
