Abstract：The volcanic rock in Songliao Basin is characteristics of deep buried depth and complex structure, resulted in poorer S/N ratio of seismic data and lower imaging precision, which bought about difficulty in prediction of volcanic rock reservoir. In order to improve the predicting precision of volcanic rock, we used numeric modeling technique of wave equation to analyze and demonstrate the relevant parameters of geometry. The paper highlighted the optimizing the spread length, offset, surveying pattern and migration aperture, which designed reasonable geometry and clearly recognized development zone of volcanic rock by numeric simulation of forward model of practical volcanic rock, gave proof of study on wavefield characters in practical volcanic rock zone.
