摘要： 在分析东濮凹陷深层异常高压形成及分布的基础上,利用实验手段从压实成岩、溶蚀-胶结作用和砂岩、泥岩的破裂及塑性变形等多方面探讨了异常高压对深层储集层演化的影响,认为异常高压发育不仅有利于深层储集层孔、渗条件的保存,而且通过物理和生物化学两种作用改善了储集层物性,东濮深层成藏有较好的储集层条件,预示其深层有较广阔的勘探前景。

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
