In order to improve the seismic resolution the earth's absorption must be compensated.In this paper Spectrum Shape Filter(ssf) — the technology of I/O company is theoretically analyzed.A set of models are set up and based on those models forward modeling of ideal,real,and filtered seismic reflection is conducted.The results show that the amount compensated by ssf to high frequency is limited and the increase of resolution(31.1%~39.1% correspondingly) is not remarkable as well.So it is necessary to improve ssf to increase the compensation effect.
