The Catalytic Effect of Organometallic Additives on Low-temperature Oxidation of Light Crude Oil During Air Flooding

Abstract

To improve the safety of air flooding, static and dynamic oxidation experiments are conducted to research catalytic low-temperature oxidation (CLTO) technology. The results show that the additives can accelerate the oxygen consumption rate significantly. Saturates and aromatics are converted to resins and asphaltenes during low-temperature oxidation (LTO), and the addition of additives can enhance the changing trend. CLTO technology can accelerate the oxygen consumption and delay the gas breakthrough time. This study can provide guidelines to improve the safety and increase the application of air flooding technology.
