The invention relates to a method for raising the resolution of high, middle and deep earthquake data. The method comprises the following steps: performing wavelet low-frequency intercepting deconvolution to the high, middle and deep earthquake data; and then using the Q value residual amplitude equalization method to adjust the earthquake data after deconvolution; and finally, employing the time-varying cross-correlation signal enhancing method to align and level the adjacent channels in the CMP channel after dynamic calibration. According to the wavelet low-frequency intercepting deconvolution, the Q-value residual amplitude equalization and the middle and deep signal consistency enhancing method, the frequency of the earthquake channel in the middle and deep CMP channel set tends to be consistent with each other, and therefore, the same-phase superposition precision and middle and deep earthquake data resolution are increased. According to the embodiments of the invention, it is possible to reduce the field high resolution exploration cost in prospecting through earthquakes for petroleum and natural gases in middle and deep layers. It is also possible to raise the resolution of middle and deep layers reasonably and effectively in the earthquake data processing.
