In order to solve the influence of different doses of explosive excitation on seismic data quality,the authors analyzed and tested the seismic data in indoor processing.Using such means as autocorrelation statistics,frequency statistics,and energy statistics of the seismic data,the authors found the correlation of explosive excitation weight and seismic wave characteristics and,by way of point-line-plane analysis,revealed the changes related to seismic data quality.On such a basis,the authors put forward the quantitative analysis and iterative processing technology in data processing and,by application of spherical divergence and absorption time and frequency domain compensation as well as the surface consistent amplitude and surface consistent deconvolution technique,the authors solved the problem of the influence of different doses of explosive excitation on the quality of seismic data with relatively satisfactory processing effect.The results provide reliable seismic data for the increasing production of the old oilfield in CY City
