Abstract：With the use of 2-U Fourier transform,CT technique is introduced into seismic data processing,thus developing new CT integral transform formulas.The truncation effect is analysed,and forward weighting transform for improving directional resolution is advanced,CT integral transform is described as follows,Forward CT integral transform decomposes wave field according to wave direction so as to convert signals from time-space domain into time-slowness domain,where strong wave-forms correspond to events in time-space domain and the locations indicute wave directions and arrival times,CT integral inverse transform means composition of plane waves,in other words,time-slowness domain data are converted into time-space domain data.It is discussed how we use CT integral transform to suppress multiples,random noises and regular noises,and to make wave-field separation and trace interpolation,The application of these methods to data processing brings good geological results.
