Effect of Deep Abnormal Pressure on Reservoir Evolution in Dongpu Sag

Abstract

Abstract: The formation and distribution of deep abnormal pressure in Dongpu sag is analyzed. The effect of the abnormal pressure on deep reservoir evolution is discussed by lab experiments of compaction, diagenesis, pressolution-cementation, breakup and plastic deformation of sandstone and mudstone, etc. It is recognized that existence of abnormal pressure is not only available for porosity and permeability preservation of deep reservoirs, but also for improvement of their petrophysical properties in physical and biochemical mechanisms. The deep reservoir in Dongpu sag is in good conditions, showing a broad prospect for exploration.

Key words: Dongpu sag, abnormal pressure, deep reservoir, secondary porosity, halite
