Abstract: Seismic inversion technique plays an important role in reservoir prediction.In recent years,the seismic inversion technique is applied more extensively in petroleum explora- tion and development,and becomes a reliable reference for submitting reservoir and well sites.Taking Fuyu and Gaotai- zi oil horizons in the north of Qijia area in north Songliao ba- sin as an example,the application effect of quasi-acoustic wave in reservoir prediction and the approach of applying seismic inversion in reservoir prediction are introduced.The seismic inversion technique can predict reservoirs more accu- rately,and can present more reliable basis for petroleum production as well.
