- 摘要:
- 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。
- Abstract:
- Aiming to this problem that the feature of anisotropy is prominent and extensive for cross-hole seismic wave field and the conventional modelling method based on isotropy theory cant meet the needs of high accuracy and resolution imaging for cross-hole seismic data anymore, this paper theoretically analyzes the wave characteristic in VTI medium and presents a modelling method for VTI medium. Using the model established by this method, the modelling result of synthetic cross-hole seismic recorded by finite difference method is well coincident with the real cross-hole seismic records in both kinematical and dynamical characteristic, which proves the availability of this method.
