Firstly, the similar characteristics in the flow section of all the gas-water flow patterns in the horizontal or inclined pipe are extracted. According to the abstraction of the characters, four material distribution models are built up. Secondly, the electromagnetic image logging measurement in response to all the four material distribution models are simulated by the finite element method and the peculiarity related with the flow patterns of each response is analyzed. Thirdly, the character related to the models is computed as a parameter from the measurements. By using the parameter, the stratified model is separated from other models and water holdup rate is computed. Finally, a pattern recognition method is used to identify the transformation rules of the material distribution models in the flow section; the gas-water stratified flow is distinguished. With this method, the gas-water stratified flow patterns can be identified and the water holdup rate can be computed, and the method is quicker and more accurate than analyzing reconstructed images.,

articleAbstract=针对大斜度或水平气井中最常见的气-水分层流动，研究利用电磁流动成像测井判别分层流和波状流的方法。首先，分析水平或微倾圆形管道内较常见的气-水两相流型在管道截面上的特征，建立流体分布模型；其次，模拟流体分布模型的电磁流动成像测井响应，分析仿真数据特点；再次，提取仿真数据中与流体分布相关的特征参数，该参数不仅用于判定流体分布模型，而且用于计算分层流模型中的水层高度，从而求取持水率；最后，研究水平气-水两相流型在流动截面上流体分布模型的变化规律，实现气-水层流判别。仿真数据研究结果表明，用这种方法可以实现气-水层流判别和持水率求取，避免了图像重建的过程，计算简单速度较快。,
