Abstract: With the development of the seismic anisotropy theory, the multi-wave technology plays an increasingly important role in the reservoir fluid detection. Compared with longitudinal waves, the acquisition of longitudinal waves and transverse waves in multi-component seismic provides the possibility of improving the prediction accuracy of reservoir fluid. Based on the 3D 3-component seismic data gathered from Wellblock S48 in Tahe oilfield and regarding the fractured-vuggy carbonate reservoirs, the analyses on vp/vs, Poisson’s ratio, weakness ratio and inversed parameters, Lame Constant and density are carried out and fluid prediction is performed by using multi-wave attribute seismic technology. Compared with conventional P-wave frequency spectrum analysis technique, the multi-wave seismic prediction technology can improve the accuracies of reservoir prediction and hydrocarbon identification, and reduce the uncertainties of conventional P-wave fluid prediction method
