摘要：
The content of carbonate in natural core was determined, the exothermic effect of sulfuric acid and water were analyzed and the increasement of core permeability due to the injection of sulfuric acid was determined. Finally, through the laboratory oil flooding test, the effect of sulfuric acid flooding was evaluated and the injection volume of sulfuric acid was optimized. The experimental results show that the effect of sulfuric acid flooding to improve oil recovery is well and the oil recovery can be increased by 7-10% based on water flooding; so we propose that injecting concentrated sulfuric acid into formation to improve oil recovery after water flooding in oil field.
