With the 3Dcoherence cube technique, the seismic exploration has nearly made a new breakthrough in the seismic data interpretation. Compared with the previous methods, this technique is effective in solving such geological problems as faults and some special lithologic bodies. By calculating coherency between seismic traces, we can realize the conversion from 3Damplitude data to coherence attribute data. However, as the running time of the traditional methods is always very long, such methods can not satisfy the practical need. In this paper, the authors, based on an analysis of the basic theory of coherence cube, put forward the recursive method, developed its software and used the technique successfully in the TJHarea of Dagang oilfield.
