Discussion of Undercompaction of Rocks一一And impossibility of hydrocarbon expulsion during rock compression

Abstract

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
