Abstract: Due to the special condition of seismand geology in Liaohe Basin, the predominant frequency of seismic data collected in deep strata before concentrated around 20-25Hz.These old seismic data has become the"bottleneck"of exploration work in Liaohe area,which has restrained the further exploration and development of LiaoheOilfield.To meet the fine structure interpretation and oilreservoirs description requiring for seismic data, Liaohe Oilfield tackled the key problemusing a series of acquisition methods in Damintun area, formed a completed fined 3-Dseismic acquisition technique, which is applied and made better effect in secondary collecting.

Key words: best lithologic induced, geophones with serials connection, low-noise reception, Liaohe Basin
