摘　　要：稠油不同于常规原油,高黏度和高凝固点特性使其难于用常规方法开采,火烧油层是有效的热力开采方法之一。利用TG-DSC技术研究稠油氧化燃烧过程,对其质量、热量变化和动力学进行分析。研究发现,稠油在有氧氛围中受热主要发生氧化燃烧反应,在510℃可完全反应。反应过程分为三段,包括低温氧化(LTO)、燃料沉积(FD)和燃烧,其中燃烧又分为低温燃烧(LTC)和高温燃烧(HTC)。Enhanced oil recovery, especially in heavy crude oil, has attracted much scientific attention,because of its large propotion in character of high viscosity and In-situ combustion（ISC） is one oil and gas resources. Unlike conventional oil, heavy crude oil has the poor mobility and it is difficult to exploit by common technologies. of the effective Enhanced Oil Recovery methods. Thermogravimetry （TG） and Differential Scanning Calorimeter （DSC） technologies were employed to study the oxidation and combustion of heavvy crude oil. The weight loss and heat change of heavy oil were investigated, and reaction kinetics was computated. Results showed heavy crude oil can be burnt in oxygen atmosphere at the temperature of 510 ℃. The combustion process can be low temperature oxidation （LTO）, fuel deposition （FD）, combustion which combustion （LTC） and high temperature combustion （HTC）. divided into included low three phase, temperature
