The seismic exploration of volcanics reservoir has been paid attention to geophysical industry,especially the volcanica reservoir makes prediction very difficult because of intrinsic complexity of its lithology and reserve space.Using the real data of deep volcanics in the north of Songliao basin,the paper summarized a suit of mature reservoir prediction technique:①full 3 D subtle interpretation;②3 D seismic inversion;③seismic waveform attribution analysis;④hydrocarbon detection;and⑤seismic attribution.The above mentioned useful techniques were selected to apply combining with hydrocarbon development and gains obvious results,which shows this set of techniques is successful in prediction of volcanics reservoir and has applied and popularized value.
