Abstract: BISQ model is composed of fluid-solid action mechanics between Biot flow and jet flow.Based on BISQ model，wavefield features，propagation rule，strong attenuation and high frequency dispersion of seismic wave caused by jet flow in dual phase media are analyzed.Based on the particular seismic wavefield properties of dual phase media，when seismic wave penetrates the reservoir，the energy of top，bottom and lateral orientation of the reservoir will be different.So，the fast P wave′s Q-1 & αcan be calculated to detect hydrocarbon.This method is applied to detect hydrocarbons in clastic rock reservoir，oil/gas special distribution in the study area were detected accurately and effectively.Moreover，the detection results are verified by the actual drilling results.This method has provided a new technical support for oil/gas detection and has wide application prospects.

Key words: dual phase media, BISQ model, seismic wave, oil/gas detection, reservoir
