Using Porosity and Permeability Parameters to Construct Capillary Pressure Curves

Abstract

Abstract: It is the most direct and effective method to evaluate reservoir pore structure using capillary pressure data. Acquiring capillary pressure curves consecutively is the seeking target by geologists. In view of the finiteness of quantity of reservoir capillary pressure data, based on the analyses of various core mercury injection data, a new method for constructing capillary pressure curves using conventional porosity and permeability parameters is proposed and the relevant structural model is developed. The continuous capillary pressure curves can be constructed using this method. Comparison with core mercury injection capillary pressure data indicates the reliability of this method.

Key words: porosity, permeability, capillary pressure, construction, pore structure
