摘要: 根据岩石的变形机制,把岩石孔隙度的变化过程划分为压实和压缩两个阶段,岩石压实阶段的孔隙度呈指数规律变化,岩石压缩阶段的孔隙度保持为常数。传统理论把压缩阶段称做欠压实阶段,是一个误解。根据固体力学和流体力学的有关理论,研究了岩石在压缩阶段的体积变化关系,得出了该阶段的岩石不可能排液、当然也就不可能排烃的结论。

Abstract: Based on the mechanism of deformation of rocks, porosity-depth curves of rocks can be divided into tow periods as compaction and compression. The porosity of the former decreased exponentially, while that of the latter maintains a constant which is conventionally mistaken as under compaction period. According to the theory of mechanics of solids and fluids, the volume variation during rock compression is studied, and It is concluded that fluid or hydrocarbon expulsion in rocks is impossible during the period of rock compression.

Key words: rock, compaction, compression, under compaction
