Intelligent fault diagnosis method for electric submersible pump production well

The invention discloses an intelligent fault diagnosis method for an electric submersible pump production well, and belongs to the field of fault diagnosis of petroleum and natural gas industrial equipment. The method is characterized by comprising the following steps that a, a current card sample is collected, and a fault type is marked; b, a current card is pretreated; c, a convolutional neuralnetwork algorithm model based on an attention mechanism is designed; d, an inference interface of the convolutional neural network algorithm model based on the attention mechanism is called, the current card is diagnosed, and confirming and correcting are performed by an equipment diagnosis expert; and e, corrected case data are returned, correction training of the convolutional neural network algorithm model based on the attention mechanism is performed, and the steps c-e are repeated. According to the method, the attention network is connected in parallel to the convolutional network basic network, attention is paid
