摘要
针对目前油井井号识别效率低,识别方法效果差的问题,本文采用基于深度学习的卷积神经网络(ConvolutionalNeural Network,CNN)方法进行识别。针对传统卷积神经网络LeNet-5结构应用在井号识别中存在的不足,本文通过转换模型中卷积核大小、增加高效降维层、使用混合激活函数,三方面进行改进。经过实验,改进后的LeNet-5模型与传统网络结构相比,减少训练时间、提高准确率,在油井井号识别上具有明显的优势。
In this paper,the Convolutional Neural Network (CNN)method based on depth learning is used to identificate oil well numbers because of the low efficiency in oil well numbers recognition and the poor effectiveness of identification methods. In view of the shortcomings of the traditional convolution neural network LeNet-5 architecture in the recognition of well numbers,the three aspects are improved in this paper.They are transforming the convolution kernel size,increasing the efficient dimension reduction layer and using the mixed activation function.Through experiments,the training time of the improved LeNet-5 model is reduced and accuracy is improved compared with traditional network structure.It is obviously better than the traditional network structure in the identification of oil well numbers.
