- W3114031966 abstract "Gaussian beam method not only considers the kinematic characteristics of seismic wave propagation, but also considers the dynamic characteristics of seismic wave propagation. It overcomes the shortcomings of traditional ray method, and it has not singularity region in the wave field. In addition, the Gaussian beam has a certain effective width, and the wave field of receiver can be calculated by stacking the wave fields within the range of Gaussian beam, which greatly improves the calculation efficiency. However, a receiver point plane is often used to analyze the energy contribution of effective rays to the receiver points when synthesizing seismic records by 3D Gaussian beam method, and the surface seismic forward modeling usually use the surface as the receiver point plane. But in 3D crosswell seismic with deviated well, receiver points are not in the same plane, it is difficult to synthesize the seismic records by Gaussian beam. Based on this, this paper proposes a method which constructing the receiver point plane adaptively to solve the problem of Gaussian beam synthetic seismic record in 3D crosswell seismic with deviated well. The model test shows that this method can solve the problem of seismic forward modeling in non-coplanar 3D deviated well effectively, and provides accurate basis for further processing of crosswell seismic data." @default.
