水平管路水环输送稠油减阻模拟实验
Experiment on drag reduction of heavy oil in horizontal pipeline by water annular conveying
摘要
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.关键词
