摘要：通过实验及理论分析，系统研究了取样剪切对管输原油流变性的影响，根据鲁宁线运行工况，计算了阀门节流剪切及过泵剪切时剪切率的大小。对于鲁宁线，在同一泵站，出站处阀门节流平均剪切率是过泵平均剪切率的３倍左右。

Abstract: The effect of shearing on rheology of crude oil in transportation was studied by experiments and theoretical analysis. According to the operation of Lu-ning pipeline, the shear rates of valve throttle and pump shearing were calculated. At the same pump station in Lu-ning pipeline, the shear rate generated by valve throttle at the outlet is three times that generated by pump shearing.
Key words: shear rate; rheology; transportation; crude oil |
