盘锦线原油粘温特性及流变特性实验研究

摘要

为了给辽河油田盘锦输油管线低输量安全经济运行技术研究提供基础数据,对盘锦线原油的粘温特性及流变特性进行了实验研究,回归了盘锦线原油的粘温方程及流变方程,绘制了粘温曲线及各测试温度下的流变曲线.结果表明,当测试温度为50～80℃时,盘锦线原油表现为牛顿流体特性,且所回归的方程与实验所测数据的拟合程度较高.%In order to provide the basic data for the study on safe and economic operation under low throughput of Panjin pipeline,an experimental study on viscosity-temperature characteristics and rheological properties for crude oil of Panjin pipeline was carried out. The viscosity-temperature equation and the rheological equation for crude oil of Panjin pipeline were regressed. The viscosity- temperature curve and rheological curve at the different test temperature were drew. The results show that when the test temperature is at 50 ～ 80 ℃, the crude oil of Panjin pipeline shows Newtonian fluid behavior, and the regressed equation fits of the experimental data in higher degree.
