摘要： 通过对含水稠油和不含水稠油的热失重曲线分析,提出了利用微量油、水、砂混合物样品的热失重曲线来计算该样品中含油和含水饱和度的方法。并进行了该计算方法的误差传递分析。分析表明,该方法的计算精度可以达到3 位有效数字。将该方法应用于三维火驱物理模拟实验中,给出了不同位置的含油饱和度计算结果。

Abstract: By the thermogravimetric analysis (TGA) of water-bearing heavy oil and water free heavy oil, a method for calculating oil saturation and water saturation is presented using TGA curves of mixed samples with micro oil, water and sand. The calculating formula is derived and the trans-error is analyzed. The result shows that the accuracy of this method can reach three significant figures. The method is applied to the 3-D in-situ combustion physical model experiment followed by obtaining oil saturation values at different positions.

Key words: heavy oil reservoir, in-situ combustion, oil saturation, analysis method
