Abstract：Routine seismic imaging technique and pre-stack time/depth migration imaging technique in isotropic media have been widely applied in structure exploration and lithology exploration,great application effects have been achieved.However the seismic resolution still can not meet the need of exploration for thin reservoir and oilfield development.Based on the data gathered by integrated seismic of zero-offset VSP,8-direction Walkaway VSP,3D VSP and full azimuth 3D ground seismic,the influence of VTI medium,HTI medium and residual static correction to seismic exploration were discussed for thin reservoir and fractured reservoir in stable deposition environment.For the reservoir and fractured reservoir in stable deposition environment the study results show that the VTI medium is the main influence factor for seismic imaging resolution,it could cause 100 ms time difference within 3000M offset,for HTI medium(including non-uniform velocity and structure dip) the orientation influence is generally less than ±20 ms,but it could also affects the resolution of seismic imaging.Meantime the solution of HTI medium relative space information could help to predict fractured reservoir.In addition VTI and HTI media could directly affect the solution accuracy of residual static correction,which is based on surface consistency theory.Therefore for thin reservoir and fractured reservoir in stable deposition environment,fully considering the influence of VTI and HTI media will help us raise seismic exploration resolution and reservoir prediction ability.
