Pore types for different diagenetic phases: L: lithic clast; Q: quartz; F: feldspar. (a) Well X89, 2477.27 m: residual intergranular pore and dissolved pore development, primarily line contact between particles and surface crack development for quartz particles. (b) Well M23, 3641.29 m: strong compacted diagenesis, line contact between particles with a few residual intergranular pore. (c) Well MZ2, 4201.94 m: feldspar dissolved into intragranular pores. (d) Well M18, 3852.55 m: line contact between particles and feldspar dissolution.
