摘　　要：主要针对含水稠油的脱硫化氢模拟计算进行研究,筛选合适的热力学模型,采用实验结果与计算结果进行对比的方法进行研究,研究结果表明,对于含水量较高的稠油,在进行化工模拟计算时,选择活度系数类的热力学模型计算比较准确,如Wilson、NRTL和Margles方程等,三者中又以Wilson方程的平均计算误差最小,最小相对误差为24.9%。This paper focuses on the study of removing H_2S in heavy oil with quantity of H_2 O. The aim is to chose suitable thermal modals with different study datas. According to the sdudy,equations that belongs to the liquid activity coefficient methods,such as the Wilson、NRTL and Margles equation,can obtain more appropriate results. In these three equations,the Wilson equation's result is the most close to the field and experimental data. The minimum relative error is 24.9%.
