原油屈服值的测量特性
Characteristics of Yield Stress of Crude in Measurement

摘要: 原油屈服值测量系统条件和测量方法影响原油屈服值的测量结果,这种原油屈服值的依赖性质称之为原油屈服值的测量特性。除测量系统的几何尺寸、壁面性质等因素影响屈服值外,原油屈服值的一个重要测量特性就是其对时间的依赖性,这种时间依赖性是由胶凝原油的屈服本质所决定的。如果排除测量系统的几何尺寸、壁面性质等影响因素,且能保证测量过程中屈服时间的一致性,则有可能使不同测量方法所测得的原油屈服值得到统一。Abstract: Characteristics of yield stress of crude in measurement is that yield stress measured depends on the conditions of measuring system and measuring methods. The most one of the characteristics is property of yield stress depending on measuring time. This is decided on the yielding behavior of gelled crude.
