Аннотация: The task of picking the reflectors is one of the most time-consuming tasks in interpreting seismic data. The known analytical algorithms for arranging this task are characterized by an extremely unstable solution in areas with unclear wave field behavior, interference, etc. The article describes the existing experience with machine learning for picking the reflectors. An approach for automatic picking of reflectors using neural networks is proposed, which is based on providing a solution for the segmentation task. To expand the receptive field of the neural network it is suggested to adopt the Feature Pyramid Network architecture and replace regular convolutions in the encoder with the extended ones. It is also suggested that additional layers with linear interpolation and convolutional layers have been added to the decoder to obtain masks with a resolution greater than that of the image applied to the neural network's input. The authors consider the methodology for preparing seismic data for training the neural network and post processing the resulting predictions. The results of testing the proposed approach are presented. The proposed approach was tested on a number of 2D and 3D seismic data of various quality, geographically located within the Volga-Ural, Timan-Pechera oil and gas provinces, Western and Eastern Siberia. Based on the results of testing, an acceptable ratio of training time to the quality of the resulting surface of the reflector, satisfying the requirements of production units, was obtained. The method proposed in the article allows to reduce the amount of time spent by specialists to pick the reflectors.
