Application of reservoir prediction technique in the exploration and development of lithologic oil-gas reservoirs

A technique of predicting and appraising lithologic reservoir is put forward in this paper,including: log layer interpretation and 3D seismic structure interpretation in terms of principle of sequence stratigraphy;qualitative appraising technique of identifying lithologic reservoir by seismic attribute;quantitative static appraising technique of lithologic reservoir by seismic impedance inversion and log parameters inversion;quantitative dynamic appraising technique of lithologic reservoir by log parameters inversion in wells.The technique is successfully used in the exploration and development of the lithologic oil-gas reservoir in Well SN31,improving the exploration and development of lithologic oil-gas reservoirs.
