摘要/Abstract

摘要： 基于(I)报根据pVT和Tμp图形的相似性和Patel-Teja状态方程建立的预测纯流体气、液相粘度的统一模型,通过引入常规的状态方程参数的混合规则,将其应用于二元轻烃混合物共计1894个数据点及模拟天然气高压粘度的预测,平均相对误差分别为13.78%和16.75%;应用于油藏原油和天然气高压粘度的预测,结果优于现有的有关油气藏流体粘度模型.

Abstract: Based on the similarity between pVT and Tμp relationships, Patel - Teja equation of state was used to develop a unified viscosity model for both pure gases and liquids. By using a general mixing rule for the EOS parameters, the viscosity equation was used to predict the viscosities of binary light hydrocarbon mixtures (a total of 1894 data points) and simulated natural gases, the overall average absolute deviations being 11. 93% and 16. 75%, respectively. For reservoir crude oils and natural gases under high pressure, significant improvement in viscosity predictions was observed as compared with the viscosity model currently used for reservoir mixtures.
