The invention discloses a seismic energy balancing method, a seismic energy balancing device and a computer readable storage medium and belongs to the technical field of seismic exploration. The method comprises the following steps that: seismic data are acquired; a root-mean-square energy value corresponding to current central sampling point data is calculated, wherein the root-mean-square energyvalue is a root-mean-square of amplitude energy value corresponding to a plurality of sampling point data acquired by detection points located in a rectangular window in a preset analysis time window; a balance amplitude energy value corresponding to the current central sampling point data is calculated; and the rectangular window or preset analysis time window is moved, a balance amplitude energy value corresponding to the next central sampling point data is calculated. An odd number of detection points are arranged in the rectangular window along the length direction and width direction ofthe rectangular window, the calculation of the root mean square energy value is related to sampling point data in adjacent seismic trace data, and therefore, the energy of adjacent seismic traces canbe more uniform and is continuous along axes of the same direction after seismic energy balancing processing, and the details of the seismic data can be displayed more clearly.
Description
technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a seismic energy equalization method and device, and a computer-readable storage medium. Background technique [0002] Seismic exploration technology is a technology that uses artificially excited seismic waves to propagate in the formation to explore the underground geological conditions. When the seismic wave excited somewhere on the ground propagates underground, it will generate reflected or refracted waves back to the ground when encountering different elastic strata interfaces. These waves can be recorded with special instruments to obtain seismic data. By analyzing the recorded The characteristics of the wave (such as wave propagation time, vibration shape, etc.), can more accurately measure the depth and shape of these interfaces, and judge the lithology of the formation. [0003] The amplitude of the seismic wave attenuates continuously with the increase of ...
