APPLICATION OF THE TECHNOLOGY OF RELEVANCE COHERENCE CUBE AND VARIANCE CUBE IN INTERPRETATION OF FULL 3-D SEISMIC DATA

WU You-xin FANG Han-zhen (Physical Prospecting and Surveying Party of Anhui Bureau of Coal Geology,Suzhou 234000,China)  
The technology of relevance cube and variance cube developed rapidly in recent years is a interpretative treatment technology to research the similarity between discontinuity in three-dimension data cube and neighboring seismic signal.It is conducive to recognition of the distribution of faults in the studied area before interpretation of three-dimension seismic data,to shortening the interpretation period of three-dimension data and to improvement of interpretation efficiency and precision.The technology is to make full use of the information of each CDP point and avoid leave-out of small faults with conventional sampling interpretation.It plays an important role in interpretation of all-three-dimension seismic data and takes good effect.This paper introduced the method and principle as well as the train of thought of interpretation based on relevance cube and variance cube and displayed the application example of the technology.
