摘    要:早期的管流试验装置在源,流程,温度控制,压力测量,流量控制等方面存在不足,对管流试验装置逐渐发展完善的过程进行了。由于管道中胶凝原油的启动过程非常复杂,涉及到胶凝原油热历史和剪切历史,原油的屈服特性,触变特性,粘弹性和压缩性,温降收缩和压力速度等因素,通过分析总结胶凝原油启动过程的相关理论,对原油的触变模式进行了探讨。

关 键 词:胶凝原油  管流特性  研究  管流试验装置  压缩性  触变性

Abstract:The pipe flow test device in early phase had many shortcomings in power, test pr ocess, pressure measurement and flow rate control. The paper reviews the develop ment and improvement process for the pipe flow test device. The process of resta rt for gelled crude oil in pipe is very complicated due to the thermal and shear history, the thixotropy property, the viscoelasticity and the compressibility of crude, the shrinkage caused by depression of temperature and the wave speed i n pipes and so on. The correlated theory on the restart process for gelled crude oil is summarized and the thixotropy models are discussed.
Keywords:gelled crude oil  property  compressibility  th ixotropy  pipe flow test equipment study  development
