一种计算多相垂直管流井底流压的新方法

A NEW METHOD OF CALCULATING BOTTOMHOLE FLOWING PRESSURE OF MULTIPHASE VERTICAL TUBE FLOW

半个多世纪以来 ,国内外学者已经提出了许多垂直管多相流井底流压的计算方法。这些方法主要是基于多相流处于稳态流动 ,通过各种流态模型的建立和适用条件研究 ,较好解决了多相流井底流压的计算问题。如 :Hasan -Kabir相关式、Hagedorn -Brown相关式、Aziz相关式、Beggs -Brill相关式、Orkiszewski相关式等。但是 ,至今还未见到多相垂直管流不稳定流井底流压的计算研究的专题报道。文中就此介绍一种计算多相垂直管流井底流压的新方法 。

Many calculating methods of bottomhole flowing pressure on multiphase vertical tube flow have been proposed.These methods are based on the stationary flow of multiphase fluid,through establishing various flow models and studying application condition,the calculating problems of multiphase bottomhole flowing pressure are better solved,such as Hasan-Kabir correlation,Hagedorn-Brown correlation,Aziz correlation,Beggs-Brill correlation and Orkiszewski correlation etc..The paper presents a new calculating method of bottomhole flowing pressure in unstationary flow of multiphase vertical tube flow.
