Reservoir fluid identification method and system and electronic equipment thereof

The invention discloses a reservoir fluid identification method and system and electronic equipment thereof, and belongs to the technical field of logging methods. On the basis of a Fisher discriminant analysis method, on the basis of projection, namely by searching a projection matrix, high-dimensional data points are mapped (transformed) to a low-dimensional space, so that the data points become dense, and the curse of dimensionality caused by high dimensionality can be overcome; and determining a discrimination function according to a principle that the class spacing is maximum and the intra-class spacing is minimum, and determining the class of the sample to be determined according to the discriminant function. According to the identification method, factors such as lithology, physical properties, water types and electrical properties are comprehensively considered, the fluid identification accuracy is high, and the method has a wide application prospect. 本发明公开了一种储层流体识别方法、系统及其电子设备，属于测井方法技术领域。基于Fisher判别分析方
