Abstract

The invention provides a genetic algorithm-based residual static correction calculating method. According to the method, the size of a population, the generation of the population and the variation rates of individuals are calculated with allowed maximum time shift quantity, and therefore, residual static correction quantity can be calculated automatically, quickly and efficiently, and the improvement of the section quality of subsequent processing can be benefitted.

Description

technical field [0001] The invention relates to a method for obtaining residual static correction based on a genetic algorithm. The method can automatically and scientifically determine the calculation parameters of the genetic algorithm. It is applied to petroleum seismic exploration and belongs to the field of seismic exploration data processing. It is a method for obtaining accurate high-frequency static correction. Efficient way to correct volume. Background technique [0002] my country's annual dependence on foreign oil and natural gas is extremely high, and more than half of my country's remaining oil and gas resources are concentrated in complex mountainous structures. It is imminent to discover and prove oil and gas resources in complex mountainous structures in time. The seismic surface conditions in these areas are complex, and the problem of static correction is serious, resulting in multiple coverage of the same reflection point due to the delay time difference ...
