Summary:The invention provides a time-varying and space-varying seismic data frequency division method, and the method comprises the steps: 1, determining a time-varying time window, extracting any position of a seismic data space through time-varying and space-varying control, and calculating a seismic data time-varying and space-varying dominant frequency parameter; 2, according to different geological purposes, defining a constant low-cut frequency scaling factor as rL and a constant high-cut frequency scaling factor as rH, and obtaining time-varying and space-varying band-pass filtering parameters according to the calculated data dominant frequency parameters; and step 3, according to the seismic data quality, selecting appropriate time-varying and space-varying seismic data frequency division parameters so as to meet seismic data analysis application requirements of different purposes. According to the time-varying and space-varying seismic data frequency division method, the stability and practicability of the
