【Abstract】 The reservoirs in Tahe oil field are full of fractures and cavities and behave strongly heterogeneity both in vertical and lateral directions. The conventional surface seismic is difficult to predict accuratly reservoirs in the area. The high resolution multiazimuthal walkaway VSP method was applied to the accurate prediction of reservoirs in Tahe oil field. Imaging of upgoing P and S waves reflected was realized. The resolution of seismic data and accuracy of reservoir prediction were improved. A series of seismic response characteristics of carbonate reservoirs with fractures and caves were then established and can be used as a tool in fractured reservoir prediction.更多还原
