OFP Viscoelastic Fluid Effects on Water Film Transport
SUN Lei, ZHOU Lifeng,SHEN Longshe, LIU Chang, SUN Hao,HE Yang1
Water film lubricated transport of super heavy oil is one of the energysaving technologies in the energy sector. In water film transport of super heavy oil,OFP produces a normalstress to make the water film stay steadily and no eccentrically phenomenon in the pipeline and plays a supporting role. To understand the change of the normalstress of OFP indepth in water film transport of super heavy oil, the effects of OFP to the stability of water film was analyzed through our experiments.The OFP is a viscoelastic liquid as the shear rate decreases and the solubility of OFP reduces gradually, and the normalstress difference also reduces gradually.
