QUANTITATIVE CHARACTERIZATION OF POROSITY EVOLUTION IN THE TRIASSIC CHANG 8 TIGHT SANDSTONE RESERVOIR DURING HYDROCARBON ACCUMULATION IN THE MALING AREA, ORDOS BASIN, CHINA

The Maling area in the Ordos Basin is characterized by delta front deposits.The principal oil-bearing layer, Chang 8 Member (the 8th member of the Triassic Yanchang Formation), manifests low-to-ultra-low porosity and permeability due to the interplay of depositional, toor knives serpent diagenetic, and burial processes.The reservoir exhibits pronou
