Abstract：The volcanic rock in superposed basin is important field in China oil/gas exploration. The interpretation of geophysical data has unique role on study of deep volcanic rock: using the data of high-precision gravity and magnetic exploration and electric exploration to know deep structure and large fault of basin, preliminarily trap the distribution of deep volcanic rock and shrink and lock benefit target zone of seismic prospecting for deep volcanic rock; taking seismic facies analysis, seismic attributes interpretation, structural mapping, seismic inversion and integrative evaluation as major technical means to carry out from qualitative to quantitative identification and prediction of deep volcanic rock, determine and optimize the favorable prospecting targets of deep volcanic rock. The better exploration effect has been achieved by several years' interpretation and practice. 54 volcanic rock bodies have been found totally in Songliao Basin and Jungar Basin, where 24 well sites have been provided, in which the natural gas to a different degree has been acquired in 13 wells.
