摘要

任何经验相关的应用只推荐在其有效范围内。尽管如此，在流体建模中不加区分地使用黑油相关性的情况经常发生。这项工作评估了Lasater(1958)关于溶液气油比(Rs)流体性质的相关性，特别是对于具有高CO2含量和高GOR的油。将相关结果与实验数据进行了比较，发现预测误差较大。最后，评估了Rs预测误差对流动模拟的影响。

EVALUATION OF THE SOLUTION GAS-OIL RATIO CORRELATION PROPOSED BY LASATER APPLIED TO OILS WITH HIGH CO2 AND HIGH GOR

The application of any empirical correlation is recommended only within its range of validity. Nonetheless, the indiscriminate usage of black oil correlations for ﬂuid modeling happens frequently. This work evaluates Lasater’s (1958) correlation for the solution gas-oil ratio (Rs) ﬂuid property speciﬁcally for oils with high CO2 content and high GOR. The correlation results are compared to experimental data, and high prediction errors are observed. Finally, the inﬂuence of the Rs prediction error on the ﬂow simulation is assessed.
