摘要

随着石油开采的增加，黏度较大的稠油输送受到越来越多的关注。基于自主设计的两相流水环输送稠油实验系统，模拟并开展了水环输送稠油实验。拍摄了水环发生器在不同间隙尺寸下的流动流型，分析了不同实验条件下的水环输送稠油减阻效果。结果表明：水环输送可以大大降低管道输送过程中压降；结合实验和模拟，水环发生器间隙尺寸在0.9～1.4 mm时，水环的减阻效果最好；流速增加会增大单位管道上的压降，降低水环输送的减阻效果。

Abstract

With the increase of oil exploitation

the transportation of heavy oil with higher viscosity has received more and more attention. Based on the self-designed two-phase flow water annular transport heavy oil experimental system

the water annular transport heavy oil experiment was simulated and carried out. The flow pattern of the water annular generator under different gaps is captured

and the drag reduction effect of heavy oil transportation by water annular under different experimental conditions was analyzed. The experimental and simulated results show that the pressure drop in pipeline transportation can be greatly reduced by water annular conveying

and the water annular generator has the best drag reduction effect when the gap size is 0.9—1.4 mm. The pressure drop per unit pipeline will increase with flow rate

and high flow rate will reduce the drag reduction effect of water annular transportation.
