Abstract：The article describes the method for modeling full wave field in 2-D viscoelastic medium.The method is characterized by the following essential points:·The travel time is decomposed into horizontal component and vertical cornponent.·The forward modeled records of time-space trace gathers,which include various wave fields of reflected P-wave,converted wave,multiple,refracted wave and surface wave,can be produced only by considering how incident angle varies with offset,without tedious ray tracing done,under the presupposition of seismic linear source.·Cross-borehole seismic section and VSP section can also be modeled successfully.
