Abstract

Abstract: Sandbody in Fuyu Reservoir is distributary channel deposits of river-deltaic environment. The reservoir changes intensely horizontally and features in low porosity and low permeability, which is difficult to be predicted and identified. For the bottleneck of exploration and development in the oilfield, on the basis of geology study including sublayer sequence stratigraphy and sedimentary microfacies, channel genesis and channel width are analyzed, technical research, such as poststack frequency-divisional processing, anisotropic research, and prestack elastic and acoustic impedance inversion, is carried out, which is applied well in channel description of Fuyu Reservoir.

Key words: Songliao Basin, channel sandbody identification, poststack frequency-divisional processing, seismic attribute analysis, anisotropy, prestack elastic inversion
