Abstract: 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.
