| 摘 要： | 正确地描述湿蒸汽两相管流特性，对于深井压降和热损失等参数的准确预测非常重要。本模型结合Mukherjee和Brill(1985)的倾斜管下降两相流关系式，考虑了流向和井斜角，对于日益发展的水平井注蒸汽动态预测具有实际意义。所采用的四阶龙格一库塔法数值解法对计算的起点位置的选取是任意的，可由井口注入参数计算井底条件，也可按预计的井底参数预测相应的井口注入条件，这样便于在注汽方案设计工作中考虑井筒与注汽层的协调。采用公布的现场试验数据对模整进行了评价井与其它模型作了比较，计算结果较其它模型更接近实测数据。

| Abstract: | This paper presents an improved model for predicting performance in steam injection wells,which incorporates a downward two-phase flow correlationspresented by Mukherjee and Brill(1985) and account for flow direction and wall inclination angle.It can be used for predicting performance in horizontal steam injection wells that ara developing.The fundamental differential equation in the model is solved numerically by using a fourth-order Runge-Kutta method in which the choice of the start position is arbitrary,it is convenient to take into account the coordination between wellbore and injection layer. |
