针对井间地震数据各向异性特征明显、常规的基于各向同性介质的建模方法难以满足井间地震高精度和高分辨率成像的需要这一问题,在理论分析VTI介质中波场特征的基础上,给出了基于VTI介质模型的井间地震建模方法和实现过程,利用该建模方法得到的模型模拟出的合成井间地震记录与实际井间地震记录在波场的运动学特征和动力学特征方面都有较好的一致性,并验证了该方法的有效性。
In view of the obvious anisotropy characteristics of crosswell seismic data, the conventional isotropic media-based modeling method is difficult to meet the needs of high precision and high resolution imaging of crosswell seismic. In the theoretical analysis of wavefield characteristics in VTI media Based on the above, the method and realization process of cross-well seismic modeling based on VTI medium model are given. The kinematic characteristics of synthetic cross-well and actual cross-well seismic wave in the wave field are simulated by the model obtained from this modeling method And kinetic characteristics have a good consistency, and verify the effectiveness of the method.
