Application of 3-D Integrated Interpretation Technique in Liyuan Area in Biyang Depression

Integrated interpretation is to fully study the targets through integration of interpretation and processing, integrated interpretation of different data sets, integrated interpretation with different software and full 3-D interpretation. It is direct, accurate and reliable. The accurate locations of boundary faults are determined and reverse faults are verified to exist in Liyuan area through integrated interpretation of the 3 -D seismic data; structure interpretation is more close to its actual shape after research on velocity; reservoir recognition and prediction are carried out with 3 -D visualization software and the results are of high quality.
