Estimation of oil-water relative permeability curves from production logging data

Xie Jin-zhuang, WU Xi-ling

Abstract

The empirical formulas for oil and water relative permeability in the Daqing Oilfield are obtained by analyzing the characteristics of the oil-water relative permeability curves of 128 cores from 9 sealed coring wells. The correlation between the reservoir water cut and water saturation is derived based on the percolation mechanics theory. The parameters in the empirical formulas are determined with the correlation and the oil cut, water cut and water saturation from the production logging data. The oil-water relative permeability curves obtained in this way agree with that obtained from the core analysis.
