Abstract

The invention discloses a seismic data reconstruction method, device and equipment and a medium, and is applied to the technical field of seismic exploration and used for solving the problems of relatively high acquisition cost and relatively low exploration precision of high-density seismic data in the prior art. The method specifically comprises the following steps: training a deep neural network model representing a nonlinear mapping relationship between sparse seismic data and high-density seismic data by using the sparse seismic data and the high-density seismic data of each geologic model, so that the finally trained seismic data reconstruction model can obtain the high-density seismic data according to the to-be-reconstructed sparse seismic data, thereby achieving the reconstruction of the seismic data, reducing the collection cost of the high-density seismic data, and improving the exploration precision of the high-density seismic data.

Description

technical field [0001] The present application relates to the technical field of seismic exploration, in particular to a seismic data reconstruction method, device, equipment and medium. Background technique [0002] With the continuous development of seismic exploration technology, the exploration targets are becoming more and more complex, and the requirements for exploration accuracy are getting higher and higher. [0003] However, during the exploration process, the acquisition cost of high-density seismic data is high, and affected by objective factors such as acquisition conditions and bad sectors, the exploration accuracy of high-density seismic data is low. Contents of the invention [0004] Embodiments of the present application provide a seismic data reconstruction method, device, equipment, and medium to solve the problems of high acquisition cost and low exploration accuracy of high-density seismic data existing in the prior art. [0005] The technical scheme ...
