摘　　要：以电磁流动成像测井传感器的数值模拟为基础,在已有的正演仿真平台上,采用正交试验方法对传感器进行优化设计。根据对试验结果的统计分析和方差分析,得到传感器几何和材料参数对目标函数即全水/全油电压值变化的影响程度依次为管壁厚度>管壁介电常数>电极径向插入深度>电极张角,按优化后参数组合计算,在置信度为95%的情况下性能参数指标可达到原来的3.6301～5.8741倍。结果表明,正交试验方法可以有效地解决电磁流动成像测井传感器优化设计问题。Orthogonal test was used to the optimization design on the basis of numerical simulation of flow electromagnetic tomography transducer.Through statistical analysis and variance analysis of the results,the influence of geometry and material parameters on the aim function which is the water-oil ratio was researched.The parameters in order of important influence are thickness and capacitance of the wall,insert depth and open angle of the pole.According to the optimal parameters combination,the target is 3.6301-5.8741 times more than its original number with 95% confidence.The results show that the optimization design of the flow electromagnetic tomography transducer can be resolved by the orthogonal test effectively.
