Theoretical Design of High Resolution Seismic Data Acquisition System

LI Ting-ting,YUAN Zi-long(Northeast Petroleum University,Daqing 163318,P.R.China)  
Because of the absorption and spherical spreading,the amplitude,main frequency and frequency band of reflected wavelet become low,which can't meet the demand of high-resolution exploration.It is proposed that the intelligent program-controlled preamplifier and spectrum equilibrating filter should be added into the seismic data acquisition system,which can compensate spherical spreading and the absorption of stratum.Theoretical models are built to verify the validity of this improvement scheme.The results show that the main amplitude,main frequency and frequency band of reflected wavelet and the effective dynamic range of system are increased differently.
