Well cementation quality evaluation method and device, electronic equipment and storage medium

The invention provides a well cementation quality evaluation method and device, electronic equipment and a storage medium, and belongs to the technical field of oil exploration, and the method comprises the steps: obtaining well logging sound amplitude image data and variable density well logging image data of a target well after well cementation; numeralization is carried out on the curve of the logging sound amplitude image data, the sound amplitude of each point on the curve is obtained, and the maximum value of the sound amplitude is determined based on the sound amplitude of each point; based on the ratio of the sound amplitude value of the target point to the maximum sound amplitude value, a relative amplitude method is adopted to determine a cementing quality evaluation result of the first well cementation interface; and inputting the variable-density logging image data into a trained convolutional neural network according to the evaluation result of the cementing quality of the first interface of well
