Abstract

The embodiments of this specification provide a seismic data interpolation method, device and equipment. The method includes: setting a regular grid based on initial seismic data; the initial seismic data has different distribution densities of seismic traces in different regions; the regular grid includes at least one regular grid point; in the initial seismic data Acquiring structural seismic data; the structural seismic data includes structural seismic data points corresponding to the regular grid points; using the structural seismic data points to obtain the structural tensor of the initial seismic data corresponding to the regular grid points; Determining the local dip angles of the initial seismic data corresponding to the regular grid points through the structure tensor; performing interpolation on the initial seismic data according to the local dip angles to obtain interpolated seismic data. In the above method, according to the seismic data corresponding to the regular grid points, the corresponding interpolation seismic data is obtained by using the local dip angle, and the interpolation of the irregularly sampled seismic data is realized.

Description

technical field [0001] The embodiments of this specification relate to the technical field of seismic signal processing, and in particular to a seismic data interpolation method, device and equipment. Background technique [0002] In the field of geological exploration, due to the influence of the environment, instruments and other factors, the collected seismic data may have problems such as missing seismic traces and insufficient sampling rate. In the case that the directly collected seismic data does not fully represent the geological structure and seismic parameters, the actual application of the direct use of the seismic data to determine the exploration and production plan may affect the normal progress of exploration and development work. Therefore, the seismic data can be interpolated to improve the accuracy of the seismic data. [0003] However, in practical applications, the acquired seismic data may be irregularly sampled seismic data, that is, the seismic data h...
