| 摘 要： | 在组分分析的基础上，采用立方型状态方程建立了计算原油体积系数的新方法。在不同压力下，对5种原油样品进行了计算。与实验值的对比结果表明，其平均相对误差为0.911%，明显低于石油工程中常用的Standing和Vazquez-Beggs经验公式，表明该方法的计算精度较高。

| Abstract: | Based on the component analysis,a new calculation method for the volume factor of formation crude oil was proposed by cubic equation of state.The crude oil volume factors for five different complex petroleum fluids were calculated at different pressures by the new method,the Standing experience formula and Vazquez-Beggs experience formula.The results show that the average absolute percentage deviation(ADD%) obtained by the new method is 0.911%, and is the smallest.It is shown that the calculation accuracy is higher. |
