摘　　要：室内PVT实验测定原油高压物性参数时，标准规定在20℃下进行油气分离并测定地面脱气油的体积，而此时高凝油已经凝固无法直接测定溶解气油比、体积系数等参数。提出了升温测定高凝油的原油物性参数的技术设想，分析了建立高温物性参数的必要性和重要性，论证了50℃作为高温条件的可行性，提出了一套高温物性参数。为了提高原油物性参数的测定精度及便于现场应用，建议对高凝油、稠油使用高温物性参数，并建议适时建立关于高温原油物性参数的行业标准，以便于推广应用。In the experimental measurement of oil PVT parameters, the temperature for gas/oil separation and volumetric measurement of stock tank oil is set at 20℃ according to China petroleum industry standards （ CPIS）. But at this temperature, high pour point oil has been solidified. Therefore parameters such as dissolved gas/oil ratio and volume factor can not be calculated directly. This paper proposes a technical idea that property parameter of high pour point crude can be measured at higher temperature, and provides analysis on the necessity and importance of high-temperature material parameters. Test temperature of 50 ℃ is advised, and a set of high temperature parameters are presented. This paper suggests that high temperature parameters should be used for high pour point crude and heavy crudeoil, in order to increase the measuremental accuracy of property parameters. It is also suggested that a CPIS for high temperature property parameters should be established to popularize its application in oilfields.
