Study on Synergistic Effect of Directional Chemical Reaction⁃Assisted SAGD under Three⁃Dimensional Physical Simulationon
Published 2025-08-01“…Changing the heat generation method to reduce water injection while ensuring heat injection is of great significance for thermal recovery.Based on the analysis of directional chemical reaction products and combined with large⁃scale three⁃dimensional physical simulation experiments, the feasibility of directional chemical reactions was verified, the expansion law of the temperature field in directional chemical reaction⁃assisted SAGD was clarified, and the characteristics of production curves at different mining stages were analyzed and evaluated.The results show that among the products of the directional chemical reaction, the liquid fluid is mainly C5-C20, and the gaseous substances are mainly CH4 and CO2; the final recovery degree of SAGD development assisted by directional chemical reaction products is 76.59%, which is 19.99 percentage points higher than that of pure SAGD. …”
