摘要
介绍了2006年SEG年会上所反映的各向异性研究的新进展,主要包括:提高速度分析精度的各向异性速度分析参数正交化方法;影响裂隙储层预测的地震波动力学与运动学特征差异分析;验证现行裂隙硬币理论模型可靠性的不规则裂隙有效弹性参数计算分析;提高计算效率的波场延拓各向异性参数参考值优选Lloyd算法;常见TTI介质不同成像方法试验效果的比较。
This paper introduces the highlights in anisotropy study in SEG annual meeting of the year 2006.Topics includes orthogonal parameters for anisotropic velocity analysis,difference analysis of the kinetic and kinematic properties of seismic waves that controls the reservoir prediction,effective elasticity of rock with irregularly shaped cracks which is used to verify the reliability of currently used circle shaped fracture model,reference-anisotropy parameters for waverfield extrapolation by Lloyd's algorithm,and evaluations of migration methods for dipping TI media.
