Title: Study on properties of HD surfactant flooding system
Abstract: On the base of surfactant enhanced oil recovery,the HD interface characteristics and core flooding experiments were studied.The results showed that HD can make ultra-low interfacial tension of water and oil under concentrations from 0.025% to 0.30% in the salinity of 6 823 mg/L.The lowest interfacial tension of the time(the original 40 min,first for 15 min) is the 63.5% of original,and the results were superior to a single by additive HDSY.It showed that the water flooding after water up to 95% can continue to improve oil recovery 24.25% by composite flooding system.
