旋流器串联运行中含油量参数的控制

Control of Paramenters of oil Content to Series Connection Cyclones in Operation

采用液－液旋流分离器进行高含水原油预分离，然后进行污水除油，可以缩短油田采出液处理流程，节约能耗，具有很大的优越性。为了提高油水分离效果，常将两台旋流器串联使用，一级保证溢流口原油含水率尽量少，二级则保证底流污水含油量尽量少，这样就存在一级和二级间的匹配问题。在旋流器的串联运行中，没有必要对第一级旋流器的底流进行严格的控制。原油预分水旋流器对脱除高含水油井采出液中的游离水比较有效，可以将采出液中的游离水基本上全部脱除，但不能脱除其中的乳化水。通过试验，分析了一级底流含水率对二级除油效果的影响，讨论了旋流器串联的优化控制问题。

It is no need to strictly control the bottom flow of the first stage of cyclone in series connection operation.To remove the free water form produced water which comes form the high water cut well, the crude preseparate water cyclone is more effective. It can remove the free water in the produced fluid completely but can' t remove the water emulsion in the produced fluid.
