摘要: 岩石存在 2 种基本的变形机制:本体变形和结构变形。致密介质在应力作用下,以本体变形为主,孔隙度不发生变化; 疏松介质在应力作用下,以结构变形为主,孔隙度发生变化。油气藏岩石为致密介质,其变形过程遵循“本体变形过程中的孔隙度不变性原则”。

关键词: 岩石, 孔隙度, 本体变形

Abstract: There exist two typical deformations for rocks:primary deformation and structural one.Tight media mainly perform primary deformation in stress process with constant porosity, while loose rocks mainly perform structural deformation with porosity changing.Reservoir rocks are tight media, which deformation process obeys the principle of constant porosity in primary deformation.

Key words: rock, porosity, primary deformation
