Abstract: Drilling operations have proven that the Chang 8 oil group is the main hydrocarbon reservoir in Zhenjing area. Most of the sands in this zone are from distributary channels. However, the distribution and characterisation of channel are still unknown. This paper mainly discusses the seismic characterisation of channel of delta front in C8 member Zhenjing oil field, Ordos Bassin. The study area is located at the southwest part of the Ordos Basin and covers an area of 1,150 km². Both major and small channels in the C8 member were interpreted. Twenty-six wells are drilled in our study area. They allowed us as well to interpret the channels which were our main target. In this study, four layers were fundamentally our interest: 'Y10', 'C6', 'C7' and 'C8'. The interpretation of channels was only studied in the area between 'C7' and 'C8' horizons. This work is the result issued by the study and interpretation of real data from the study area. The information and knowledge provided in this research paper will help and contribute a lot to understand more about the geological conditions of the study area.
