Title: Modification and Application of Tong's Chart in Low Permeability Oilfield
Abstract: The Tong's Chart for relation between water cut and recovery degree,which is used for evaluation of effectiveness of water-flooding development,is one of the important methods for prediction of recovery ratio.At present,the utilization of this method is popular in the Country.Based on the relation between water cut and recovery degree from Tong's Chart,the statistical coefficients and the boundary layer conditions are modified,in order to get the improved Tong's Chart fitting low permeability oilfields.The improved Tong's Chart is testified in the actual application at Shi-Nan 31 Oilfield.The calculation results from the improved curve are more precise and better in consistence with the reality of oilfields.
