Abstract：Starting from Zoeppritz equation, the paper discussed the feature of amplitude and phase of wide-angle reflection data and affected reasons, showed the main differentiation of wide-angle reflection from narrow-angle reflection on seismic gathers by selection of single interface and thin reservoir model, and further expounded that it is necessary to carry out the moveout and phase corrections in wide-angle seismic data and gave concrete correction method.The influence of factors such as mean-square-root velocity etc.on correction effects was also analyzed by implementing moveout and phase corrections on wide-angle reflection gathers of 4-layer medium model and stack of corrected gathers was carried out.The characters of wide-angle seismic data correction and the issues being well worth notice were obtained by theoretical study and model-experimental analysis, laid a theoretical foundation for wide-angle seismic data processing.
