Using time slice and leveled layer slice,we can explore small faults and analyze geological structures through investigating the similarity of seismic signals between adjacent traces on the seismic cu.

TSAE-Z algorithm combines time slice autocorrelation envelope detection with step-variable Zoom-FFT detection(TSAE-Z),and achieves rapid and precise detection of cyclic-stationary signals.

Because of the difficulty of identifying the shallowmid layer complex structure with microamplitude trap technique,technology and methods such as synthetical record calibration,coherent slice and time slice were applied in interpretation of structures in Baitangma offshore area,a series of identification technology of complex fault and shallowmid layer are summarized.

Its 3D seismic horizontal slices clearly display that each wave group appears such event ends as directional linear extension, the event image is dragged, the same event waveforms are apparently dislocated and suddenly changed, and a suit of waves is abruptly bended in a same direction.

Based on 3D seismic data body, it combines the interpretation technologies of binning slice, coherent body slice, horizontal slice, vertical section, bending section and inline slice to realize stereo spatial.

Sedimentary sandstone body of oxbow istracked and described using horizontal slice and 3D stereo display techniques, and its lithology is studied by analyzingreservoir depth, amplitude and frequency.

By the use of 3D seismic data interpretation techniques, such as vertical time section time slice and surface slice.
