Abstract

Abstract: In this paper,based on the present mercury-injection test samples,we establish,by using the pluralistic regression analysis method,the experimental formulas that express the relationship of pore throat size with porosity and permeability at different mercury saturation degrees of different Ordovician reservoir rocks of the centural gas field in Shanganning basin.This method is likely to be used to predict the capollary pressure curves and the size and distribution of pore throat of the sample with the conventinal core analysis data.

Key words: mercury-injection test, pore throat size, carbonate reservoir rock, Ordovician, the centural gas field in Shanganning basin
