摘要： 原油开采过程中，原油遇水能够形成比较稳定的乳化液,添加破乳剂是快速高效脱去原油中水的最有效的方法。对破乳剂与原油两相混合的流动形态进行了数值模拟，得出破乳剂在不同速度、不同入口角度下加入原油管道后两相流动的速度分布图和浓度分布图。经过对比发现，当药剂入口角度为0°，药剂流入速度越大,越有利于破乳剂的扩散，破乳剂和原油的混合效果最好，就更有利于原油的脱水。

Abstract: Crude oil can form stable emulsion with water during oil production. The addition of demulsifier is  the most effective and efficient way to remove the water in oil. The flow pattern of the twophase mixture of crude oil and demulsifier was  simulated in this study. In the simulation, demusifier was injected into the oil pipe with different velocities and inlet angles. The velocity and concentration distribution of the twophase flow were investigated. Results by comparison show that higher inlet velocity of the additive makes contribution to the diffusion of the oil demulsifier with the inlet angle of 0°， which will lead to a better mixture effect and is good for crude oil dehydration.

Key words: mixture model; demulsifier; twophase mixture; numerical simulation
