摘要
介绍了针对油藏流体及其注气体系的相态及物性的预测而开发的DGPVT软件包功能、模型及特点。基于实验数据对DGPVT软件包的预测准确性进行了检验,并与石油界知名的商用油气相态及物性计算软件包STATPACK进行了比较。
A software package (DGPVT) for predicting the phase behavior and properties of reservoir fluids has been developed. It has been extensively tested for the prediction of PVT, viscosity and wax appearance temperature of reservoir fluids (with and without CO_2-in jection). Comparison with the results predicted by using STATPACK (a commercial PVT software package for reservoir fluids developed by CALSEP A/S Chemical Consulting Company, Denmark) has been performed. Satisfactory agreement with the experimental data are obtained by DGPVT and it is comparable to the STATPACK or better.
