Keyword:  三相流测井涡轮流量计物理模型滑脱效应流型两相流波;
Abstract: 基于皮球集流涡轮流量计与放射性密度-持水率计组合仪在油气水三相流流动环中的动态测量结果,建立了预测三相流总流量的涡轮流量计物理模型,该模型考虑了等效"气液"滑脱速度及流型影响.由于流型转变与两相流运动波传播特性密切相关,还提出了基于"气液"两相流运动波传播速度特征的流型划分准则,并利用该准则在不同流型区域内提取了气相漂移速度及相分布系数2个重要的流动特性参数.最后,将研究所得的三相流流动特性与涡轮流量计物理模型相结合,给出了具有较高精度的三相流总流量预测结果,表明利用集流型涡轮流量计仍然可以有效地测量油气水三相流总流量.
