Abstract：Considering the interactive distribution of sandstone with different grain sizes in P11, P12 and P13 three sand sets of Putaohua reservoir in Gu-533 block of Daqing Oilfield, the sonic logging data is not able to totally reflect the lithologic change of strata, which further brought about difficulty in lithologic recognition and prediction of reservoir distribution. For that reason, the prediction of reservoir is carried out by studying seismic-geologic integrative interpretation technique and application strategy, which included fine structural interpretation, seismic inversion, seismic attributes analysis, information fusion technology etc. The precision of hydrocarbon detection has been improved by combination of qualitative with quantitative analyses, and geologic, logging and seismic integral idea, especially using pseudo-acoustic resistivity inversion and spectrum imaging attenuation attribute and frequency spectrum decomposition technique based on high-resolution time-frequency analysis theory.
