Abstract:Reservoirs in terrestrial lacustrine basins are characterized by strong heterogeneity,and thin beds are very uncertain to be estimated by cross-well data.Seismic data has characteristics of transversely traceable,but conventional seismic data resolution is not hign enough to depict thin reservoirs.Gabor deconvolution based on quadratic spectrum can obtain high-resolution seismic data.We use this approach to process data in Chengbei Area.A quantitative thin bed prediction including sand thickness and reservoir porosity is achieved by the joint of logging and seismic data.Favorable re-servoirs in the area are identified.
