Under The Conditions Of The Existing Seismic Acquisition In Northern Songliao Basin Seismic Exploration And Resolution Of Potential Research

High-resolution seismic exploration is a system engineering .In thispaper ,I start with the concept of resolution,and analyze the mainparameters in time domain and frequence domain and their relations.Andthen, it has brought forward that high-resolution comes from broadeningthe band of effective frequence(S/N>1) and increasing middle frequence.Subsequently,it has been put forward that what mainly effect the effectivefrequency bandwidth and middle frequence during the procrss of wave fromshooting,subsurface attenuation,receiving and processing,in whichsubsurface attenuation and data processing are laid emphasis on. Amongsubsurface attenuation,the effects of these factors arementioned:absorption decay,spherical diffusion attenuation, reflectionand transmission, thin layer effect,surrounding noise and sourcenoise;among data processing,the below factors are mentioned:staticscorrection, noise elimination, waveform consistency, deconvolution,velocity analysis, NMO, DMO, stacking,and migration. I proceed with thetheory and quantification computing,compute with real data of north areaof Songliao basin,get the effects and their results ,and ,at last,gainthe potential of high-resolution in north area of Songliao basin withavailable equipments.
