双同向旋流场中液液变质量流动压降特性研究
|
摘要
轴流式井下旋流油水分离器是一种可用于油井中进行油水分离的新型分离器,在室内对影响其压降的因素(入口流量、分流比、含油率等)进行了试验研究。结果表明,与压降相关的无量纲参数Eu主要与Re_m、F和导流片结构有关。当导流片结构一定时,Re_m为主控参数。采用无量纲参数分析法还得到了压降的计算关系式,该关系式综合考虑操作参数、物性参数等对压降的影响,适用范围更广,为轴流式井下旋流油水分离器在井下应用时的压降预测提供了指导。
Axial downhole hydrocyclone separator is a new type of separator for oil-water separation in oil well. Experiment researches were carried out indoors on the factors that influence its pressure drop such as flow rate,split ratio,oil content and so on. The results show that the dimensionless parameter Eu related to the pressure drop is mainly correlated with Re_m,F and guide vane structure. When the guide vane structure is determined,Re_m is the main control parameter. Pressure drop calculation formula is also obtained by dimensionless parameter analysis method. This formula takes into account the effect of operating parameters and physical property parameters on pressure drop,thus has wider range of application,which provide guidance for prediction of pressure drop of the axial downhole hydrocyclone separator for application in downhole.
