摘　　要：近年来,射流泵注采一体化技术在海上稠油油田的应用日益广泛。为促进该技术的大规模推广,采用实验结合数值模拟的方法,分析射流泵球头附近密封性能以及流动情况。研究得出如下结论:常温与高温工况下注采旁通阀的密封性能良好;球头形状及材料须进一步研究;过流通道附近气液两相流动引发复杂的压力与速度变化,须重点关注。In recent years,jet pump injection and production integration technology has been widely used in offshore heavy oil fields.In order to promote the large-scale popularization of this technology,the sealing performance and flow situation near the ball head of jet pump were analyzed by the method of experiment and numerical simulation.The conclusion is as follows:the sealing performance of the by-pass valve under normal and high temperature conditions is good;The shape and material of the ball head need further study;The gas-liquid two-phase flow near the flow channel causes complex pressure and velocity changes,which should be paid more attention to.
