Reservoir characterization of integrating seismic, log, and geology --a case of Daqing oilfield

摘要

By integrating seismic, well log, geologic and productive data, this paper presents a reservoir characterization of delta sandstone reservoir in Daqing oilfield. Well constrained inversion method is applied to 2D seismic lines in Puxi area because of its high resolution of inversion data. With this data, three beds of sandbodies are interpreted quantitatively. Reservoir properties of single well and all area are znalyzed based on well log processing of 30 wells and seismic properties. As the results of reservoir characterization. Oil-bearing area of Putaohua formation is predicted.
