摘要
Jurassic Ziliujing Formation in the Yuanba region,Northeast Sichuan belongs to fan delta deposition.The fan delta-front underwater distributary channel controls the development of sand body and fracture can improve the physical properties of reservoir,which together control the distribution and development of reservoirs.In view of the complex tectonics,and the difficult comparison between seismic horizon due to the oscillation and migration of riverway,this paper used the seismic horizon comparison based on the seismic frequency division technology,identified the distribution of underwater distributary channel according to the seismic facies and seismic attribute sections.Seismic data with wavelet reconstruction can clearly descript small faults.It finally determined the composite area between underwater distributary channel and fracture development belt as favorable reservoir development zone,which provided a sound basis for the future exploration.
