含蜡原油凝点附近的胶凝特性

含蜡原油的储能模量G′、耗能模量G″和损耗角δ等粘弹性参数可以表征原油内部结构特征,其在凝点附近随温度变化的特性可描述含蜡原油的胶凝特性.在粘弹性实验基础上采用相对温度对比研究了大庆、中原、胜利加剂和不加剂原油在凝点附近的粘弹特性,旨在探讨不同含蜡原油在凝点附近的胶凝特性及其在热油管道输送安全性评价中的作用,以全面评价含蜡原油的低温流变性与可泵送性.

Waxy Crude''''s Gelling around the Get Points

The viscoelastic parameters of waxy crude as storage module,loss module and loss angle can character-ize the crude's inner structure,which changing with temperature around the gel point can describe crude's gelling characteristic. To study the gelling characteristics of different waxy crudes around the gel point and how they effect on hot pipelines'safety,the viscoelasticity of some waxy crudes as Daqing,Zhongyuan,Shenglii crude and Daqing,Zhongyuan,Shengli pourt point depressed (PPD) beneficiated crudes have been studied contrastively based on the viscoelastic experiments.
