| 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试验，结果表明，胶凝原油具有典型的粘弹性固体特征，如具有蠕变／恢复特性，以及复数模量│G^*│大，损耗角δ小的特性等。小振幅剪切振荡粘弹性参数，可反映不同状态下原油的流变结构特点。

| Abstract: | The viscoelasticity of several gelled crude oils are investigated by experiment with stress-controlled rheometer(RS 75). It is found that gelled crude oil has properties of typical viscoelastic solid. The crude oil rheological structure at different states can be described with the viscoelastic parameters of shear oscillation. |

| Keywords: | gelled crude oil viscoelasticity creep/recovery shear oscillation experiment study |
