摘要
Abstract
The oxidation process of crude oil in oxygen-reduced air is complex.In order to accurately analyze the oxidation reaction of crude oil under reservoir conditions,it is necessary to carry out comprehensive qualitative and quantitative studies.In order to further explore the oxidation mechanism of crude oil in the process of deoxygenated air flooding,and to clarify its oxidation heat release,weight loss and kinetic characteristics,the thermal analysis experiment of Tazhong deep heavy oil reservoir in Tarim Oilfield is carried out.DSC results show that the increase of oxygen content significantly promotes the oxidation heat effect of crude oil,and the overall oxidation heat release and peak heat flow of crude oil increase greatly with the increase of oxygen content.TG experiments show that with the increase of oxygen content,the low temperature oxidation interval of crude oil keeps shortening,and the mass consumption in the low temperature oxidation stage is reduced.The temperature range of the low-temperature oxidation interval gradually narrows with the increase of oxygen content in the oxygen reduction air(the deepening of oxidation degree)during static oxidation.Based on the TG experiment data,the activation energy of crude oil in the low-temperature oxidation stage obtained with Friedman and OFW methods is close,and the activation energy increases with the increase of conversion rate.The average activation energy of crude oil used in the experiment in the low-temperature oxidation stage in oxygen reduced air with oxygen content of 5％is 81.04 kJ/mol.关键词
