摘要: 用控制应力流变仪RS75对新疆、胜利、长庆等胶凝原油进行了粘弹性实验,结果表明,胶凝原油具有典型的粘弹性固体特性,如具有蠕变/回复特性,以及复数模量G大、损耗角小的特性等.小振幅剪切振荡粘弹性参数,可反映原油不同状态下的流变结构特点.

Abstract: The viscoelastic properties of severalgelled crude oils are investigated by experiment withstress-controlled rheometer(RS75). It is found thatgelled crude oil has properties of typical viscoelasticsolid. The crude oil rheological structure at differentstates can be described with the viscoela-stic param-eters of shear oscillation.
