Residual static correction method and device and electronic equipment

Abstract

The invention provides a residual static correction method and device, and electronic equipment. The method comprises the steps of selecting a target horizon with a signal-to-noise ratio meeting a preset requirement from corresponding seismic model data according to pre-obtained seismic data; determining a cross-correlation relationship between the seismic data and the seismic model data based onthe target horizon, and determining difference data between a shot point and a receiver point corresponding to the seismic data by applying a cross-correlation relationship; and performing target residual static correction processing on the seismic data by applying the difference data to obtain corresponding target static correction data for performing oil exploration prediction. According to theinvention, the accuracy and reliability of residual static correction for the seismic data can be effectively improved, and the accuracy of an oil exploration prediction process of the seismic data after residual static correction can be further improved.

Description

technical field [0001] The present application relates to the technical field of petroleum exploration, in particular to a residual static correction method, device and electronic equipment. Background technique [0002] In the process of seismic exploration data processing for oil and gas resources, residual static correction is a conventional processing method and an essential method in the data processing process, which is usually carried out multiple iterations with velocity analysis. Therefore, the effect of the remaining static correction amount is the basis of subsequent routine processing, which seriously affects the imaging quality and is an urgent problem to be solved. [0003] The existing residual static correction method generally calculates the residual static correction amount (only the time difference), and then corrects the remaining static correction amount by means of data translation. This processing method can generally meet the residual static correcti...

Problems solved by technology

[0004] However, due to the situation of residual static correction caused by different seismic wavelets in seismic data is very common, and the existing residual static correction methods will treat the residual static correction caused by different seismic wavelets when dealing with this situation. The static correction amount is treated as a conventional residual static correction amount, so that the corrected stacked section has events that are out of focus, not smooth, and may even jitter.

This situation not only affects the subsequent processing, but also affects the effect of superimposed imaging
