摘要
基于油气水多相流混合物在管道内流动时的流体压力和压差信号 ,经特征提取和模式识别的方法实现了油气水多相流流型的在线识别。具体介绍流型识别的基本原理 。
On the basis of the signal of fluid pressure and differential pressure while the mixture of multiple-phase stream, i.e., oil, gas and water is flowing in the pipeline, and through the methods of extraction of eigenwert and mode recognition, on line streamling recognition of multiple phase stream of oil, gas and water is implemented. The basic principle of streamline recognition, the hardware structure and software design of the instrument are introduced concretely.
