Pore throat size prediction from routine core analysis data of carbonate rocks in Song Hong basin
Abstract
Mercury Injection Capillary Pressure (MICP) is usually used to characterise reservoir rock, evaluate seal capacity and detect the location of hydrocarbon accumulations. However, mercury injection tests cannot be conducted in some cases due to cost or sample amount issues.
In this study, the empirical equation is investigated to calculate pore throat size from routine core analysis data when mercury injection capillary pressure data is not available. The relation between permeability, porosity and pore throat size is detected by using multiple regression analysis on 50 carbonate samples data of Song Hong basin.
