热重法测定火驱原油的最低燃尽温度初探

Lowest burned out temperature of fire flooding oil by thermogravimetric method

用热重法对新疆九6区原油进行了不同条件下的实验,根据失重曲线分析出,不同条件下不同温度段的失重率及残渣率,通过对曲线特征及样品最终表观现象的对比分析,推测出新疆九6区原油的最低燃尽温度,为新疆油田在九6区开展火驱先导实验提供指导。

Experiments of the crude oil of the nine six area of Xinjiang oilfield were performed under different conditions by Thermogravimetry. Weight loss rate and residue rate were obtained according to the weight loss curves. Combining curve characteristics and sample facial phenomenon, the minimum burnout temperature of the nine six area of Xinjiang oilfield was speculated. This temperature can provides guidance for fire flooding process of the nine six area of Xinjiang oilfield.
