A completely new method of chemical flooding，the viscosifying emulsion-enhanced surfactant flooding technology，was put forward for extra-high temperature reservoirs. Its core part is to develop a viscosifying emulsification flooding system with good temperature resistance property，tackifying emulsion and high displacement efficiency for EOR in the extra-high temperature reservoirs. The viscosifying emulsion-enhanced surfactant（CH-13）was designed for reservoir temperatures of 90 to 130 °C，whose main performance is tackifying emulsion and the main agent is alkanolamide polyoxyethylene ether carboxylate. The results show that water soluble index increases quickly with the increase of CH-13 mass fraction in the concentration range of 2%-5%. When the water phase volume is less than 55% of the total volume，CH-13 can promote the formation of W/O emulsion whose tackifying emulsion ratio can reach 300%. The core displacement experiment showed that the oil recovery was improved by 15.8%-20.2% when emulsification/super-low IFT surfactant solutions were injected into the system alternately for several times.
