Abstract: The wide-azimuth and high-density seismic exploration technique is widely used at the present time and has gradually become a main trend in the exploration sector. The processing methods for 5D seismic data have been well developed but the corresponding interpretation methods are still in the preliminary stage. The traditional software is not able to analyze 5D seismic data. Aiming at development of wide-azimuth and high-density seismic interpretation technique family, Bureau of Geophysical Prospecting (BGP), CNPC, has created GeoEast-Easy Track (ET) interpretation software for 5D seismic data. This interpretation software package has the unique modules for analysis, merger of data, comparison of slices, imaging of geological bodies, carbonate rock carving, interpretation of 5D data and interpretation of frequency, breaking the bottlenecks of loading, saving and calculating and displaying for the TB-level data. It perfects the company’s key seismic exploration technique series and becomes unique in three areas of software platform, 5D pre-stack interpretation and industrialization of carbonate rock reservoir recognition. As the company’s unique interpretation software platform, it has been widely used both at home and abroad. When used in Tarim Oilfield, it helped improve precision of fractures by more than 20 percent and drilling success by more than 10 percent, solving the complicated geological problems in China and playing an important role in improving oil and natural gas exploration and development success.

Key words: 5D interpretation, wide-azimuth, mass data, carbonate rock fracture-carving recognition
