高含水原油对水力旋流器预分离性能的影响

简述了高含水原油经水力旋流器分离时出现乳化的原因， 讨论了影响水力旋流器高含水原油预分离性能指标， 并对影响高含水原油预分离性能的重要参数———旋流器入口流量、分流比、压降和溢流口直径等分别进行了试验。试验结果表明， 当水力旋流器的流量、分流比和压降比控制在一定范围内时， 选择适当溢流口直径才能同时提高分离效率和脱水效率， 使高含水原油预分离后溢流的含油浓度满足生产要求， 底流口污水的含油浓度也满足后续除油工艺要求。

Influence of crude oil with high water content on separation performance of hydrocyclones

The factors causing emulsification in separating crude oil with high water content are analyzed, the parameters influencing the separation performance of hydrocyclone are discussed, and the inlet flow rate Q , split ratio F , pressure drop and the diameter of the overflow D u are tested. The result of the test shows that, when Q , F and differential pressure are controlled in a certain range, the separation efficiency can be improved by selecting proper D u to make the oil content satisfy the requirement of production.
