Abstract

The invention provides an engineering seismic exploration energy automatic balancing method and device. The method comprises the following steps: acquiring seismic data; according to the signal-to-noise ratio of the seismic data and the seismic trace number of the seismic data average energy, obtaining energy adjustment intensity; and performing energy adjustment on the seismic data according to the energy adjustment intensity to obtain seismic data with balanced energy. According to the method, energy compensation can be better and automatically realized, the operation efficiency is high, a better balanced stratum profile can be obtained on the basis of less human intervention, the fidelity is high, the stratum and rock-soil characteristics are better kept, and the geological anomalous body is obvious.

Description

technical field [0001] The invention relates to the technical field of engineering geological survey, in particular to an automatic energy equalization method and device for engineering seismic survey. Background technique [0002] At present, there are large energy differences in engineering seismic exploration data in different periods, and there are energy blank areas on the post-stack section, which is not conducive to information fusion and comparison. Therefore, the energy balance technology for engineering seismic exploration is still relatively weak. [0003] Existing methods mostly use single-channel automatic gain (AGC) technology for energy balance. However, AGC technology has poor fidelity and will destroy the amplitude characteristics, especially for some special geological anomalies (geological disasters) such as shallow gas, The water-rich fault zone or fault shadow is easy to play a destructive role. Contents of the invention [0004] The invention provide...
