Method for improving resolution of post-stack seismic data

The invention provides a method for improving the resolution ratio of post-stack seismic data. The method for improving the resolution ratio of the post-stack seismic data comprises the steps of 1, collecting the post-stack seismic data; step 2, selecting a channel of seismic data; 3, selecting a first sampling point of the seismic data; 4, calculating the square of the amplitude of the sampling point; 5, calculating the squares of the amplitudes of all sampling points of the seismic data; 6, processing all data according to the steps 2-5; step 7, filtering processing is carried out; and step 8, outputting a result profile. According to the method for improving the resolution of the post-stack seismic data, a proper reference signal is selected, weak signal compression wavelets are extracted by using a correlation detection principle, the signal-to-noise ratio of the post-stack seismic data can be improved, and the resolution of the post-stack seismic data can be improved. 本发明提供一种提高叠后地震资料分辨率的方法，该提高叠后地震资料分辨率的方
