Abstract:Through literatures investigation and study, the paper expounded the development situation of wide-azimuth exploration abroad and at home,clarified the definition of wide azimuth and gave a part of application cases. The paper listed the demands on designed acquisition parameters such as folds, bin size,maximum offset and minimum offset etc in wide-azimuth seismic data acquisition and gave some common-used wide-azimuth geometry at home and abroad. Based on that,the paper pointed out the main issues present in the wide-azimuth processing, introduced azimuth processing approaches such as azimuth travel-time correction, apparent anisotropic normal moveout, 3-D Kirchhoff summation DM0 and azimuth velocity spectrum a-nalysis and gave a simple processing flow. Talking about the interpretation of wide-azimuth acquisition data,the paper suggested that it should try to use complex seismic attributes aside from well u-sing common seismic attributes such as coherent, amplitude and phase.
