Reservoir prediction technology based on wide-bandwidth azimuth seismic data

Wide bandwidth, wide azimuth and high-density seismic data are important development directions for seismic exploration in recent years. The seismic data not only realize the collection of three-dimensional seismic data with small distance, number of avenues and high density, but also realize the transformation from narrow azimuth to wide azimuth. In recent years, with the development of technology, the acquisition, processing and interpretation of three-dimensional seismic data based on broadband, wide azimuth and high density have become an important development direction of exploration.

In the actual project research process, if it is necessary to predict the reservoir of the "two wide" seismic data, how to extract the seismic parameters in the seismic data to the greatest extent is the focus of the research. Among them, the technical difficulties mainly include azimuth optimization and wide frequency wavelet extraction. In addition, the use of wide azimuth seismic data for ground stress and crack prediction is also one of the key contents of the research work.
