    Abstract: Based on diagenetic evolution, reservoir diagenetic facies evolution was restored in burial history through quantitatively calculating the original porosity reconstructed by compaction, cementation and dissolution using core measurement data. The essence of this method was illustrated and its effectiveness was demonstrated using Paleogene lake sedi... Show More
