Abstract：It is very difficult to predict volcanic rock reservoirs,especially in low-exploration areas with very few core and well data.Volcanic rocks are usually identified with seismic facies,seismic attributes and coherent analysis.However a large amount of well data is needed to constrain seismic data due to its quality limited.To overcome this difficulty,we utilize an improved wavelet transform for seismic data reconstruction based on frequency division to improve seismic data quality,and predict ancient volcanic distribution characteristics with seismic facies,forward modeling,seismic attributes,and seismic slices.This approach is used to predict volcanic rocks in Mulei Sag,Junggar Basin.The following understandings are obtained:① When the frequency of the division reconstruction is lower than the dominant frequency,the energy is reduced and the resolution is low.When the frequency of the division reconstruction is higher than the dominant frequency,the energy will gradually decrease,and much higher frequency will harm the signal-to-noise ratio; ② Based on volcanic rock forward modeling,ancient volcanic tops show strong reflection,and inner cones show weak reflection.Due to lithologic changes,the amplitude on cone sides increases gradually.The strata on volcanic cone sides overlap to the center.Volcanic channels have internal short axis seeming; ③ RMS amplitude attributes which show low values are very sensitive to pyroclastic rocks near ancient craters.Pyroclastic rock mainly represented by messy mounds,is one of the favorable reservoirs; ④ Volcanic rocks are distributed along two NNE stripes and they are more in the north and less in the south.Finally,three favorable volcanic reservoir zones are predicted based on our study.
