Abstract：Mufti-wave seismic technique is new and very effective technique for marine oil exploration and development.Through study of elastic petrophysical rule in Yingge Sea Basin with super-high temperature and superpressure,the paper discovered that the velocity ration of P-wave and S-wave and Poisson ration is very sensitive to lithology of bed and fluid content;on that basis,the template of predicting deep lithology and gas-bearing bed in Yingge Sea Basin and Basin of southeast of Hainan Island has been made according to Poisson ration and combining the wave impedance of P-wave and S-wave seismic data to predict lithology and gas reservoir for LD8-3 structure.Prediction results showed that there are mufti-sets of gas reservoir in deep of LD8-3 structure which have large reservoir area and considerable prediction reserve,so that it indicated a good exploration prospect in deep of LD8-3 structure.
