WebBased on the results of rate-controlled mercury-injection experiments, the microscopic pore-throat structure characteristics of tight sandstone in Sha-1 Section and tight limestone in Da’anzhai Section of Sichuan Basin were quantitatively characterized. The results show that the pore radius distribution characteristics of tight oil reservoirs are similar. The main … WebThe sole use of median pore-throat radius to predict permeability indicates that r 50 may control the fluid flow in porous media. For consolidated porous materials (rocks) this …
