Abstract：In this paper we discuss the system identification based on ARX model for seismic resolution improvement. Supposing seismic wave attenuation in formations is linear system, seismic data and logging data are respectively input and output, the reverse absorption system response can be evaluated based on ARX model. And then it can be used to recover attenuated high frequency component and improve seismic vertical resolution. Test results on model and real seismic data show that the proposed approach can significantly improve seismic vertical resolution and broaden its bandwidth about 15 Hz while the main features of the original seismic data remain the same.
