Abstract：The signal/noise ratio of borehole-side seismic data causes direct influence seismic horizon determination. Thus,improving the signal/noise ratio of borehole side seismic data is important work in data processing. By taking VSP upgoing wav as reference signal and using LSI. algorithm,we do self-adaptive processing of bore hole-side seismic data to improve their signal/noise ratio. Generally speaking,the processing result will be optimum when reference signal is linearly correlated t seismic reflection wave,but uncorrelated to noise;otherwise,the upgoing wave o VSP data can not be taken as reference signal.
