This paper analyzes the influence factors on seismic data resolution according to the data of Liaohe Oilfield,proposes a high resolution processing technology on the basis of protecting and improving signal-to-noise ratio of high frequency component,and several ways of improving resolution are worked out.This had been used in seismic data processing in Liaohe oil province.The weak reflector on the resulting profile is clear and shows rich geological information. The predominant frequency of exploration target had improved from the original 20～25 Hz to 30～45 Hz.This was helpful to the following inversion and lithology interpretation,and provides important basic data for finding subtle reservoirs.
