Abstract：The offsets and folds increased along with the constant improvement of seismic field acquisition methods and the gradual increase of field-acquired channels,and S/N ratio of seismic data has been greatly improved,especially along with the gradual improvement of AVO techniques,it is necessary to renew the knowledge of the AVO characters of seismic data in Daqing area in order to better identify the lithology and detect the oil/gas anomaly.The area of the AVO study is selected in 3D work area of Songzhan Sheng-81 well,the obvious AVO anomaly is obtained from the AVO processing and analysis for inline 142 of Sheng-81 well and AVO forward modeling is carried out by using logging trace associated with Sheng-81 well,the results proved that there exists AVO anomaly in Sheng-81 well.The deep volcanite is discovered by 3D AVO techniques and the channel position of volcanic eruption is preliminarily determined.
