Abstract: In Jilin Oilfield, with the development of exploration technology, the old channel evolves into the preferred target for lithologic exploration because of its characteristics like good physical properties and high productivity. But channel identification is still difficult in seismic interpretation because of the limitation of seismic data quality. In view of the actual geological condition of the fourth member of Quantougou Group in Changchunling Region, based on seismic attribute analysis, frequency scanning, characteristics inversion, seismic facies analysis, and visualization sculpture, the methods for old channel identification are carefully selected. The working flow of the method applicable to oil channel identification in Jilin Oilfield is figured out, offering technical support for the development of capacity-building and deployment of exploration wells.

Key words: Changchunling Region, old channel, reservoir prediction, accurate sculpture, working flow
