Study on Palaeogene sedimentary source in the south of the Western Depression,Liaohe Oilfield

In order to expand the exploration area in the Western Depression of Liaohe Oilfield, channel sand reservoirs have been highlighted in exploration work. The distribution of Palaeogene channel sand in the south of the depression has been studied by using techniques of fine seismic data interpretation and attribute analysis based on sequence stratigraphy study by joint processing of 3D pre-stack time migration data. The rule of sedimentary source migration has been generalized. This study provides reliable basis for sedimentary facies study and target optimization.
