本文在考虑油藏内流体影响的基础上, 进一步讨论了裂缝诱导各向异性的极化角和方位角的影响, 对裂缝诱导TTI (tilted transverse isotropy)双孔隙介质模型进行了研究. 在裂缝诱导HTI (horizontal transverse isotropy)双孔隙介质理论的基础上, 用Bond变换推导了裂缝诱导TTI双孔隙介质的柔度系数矩阵和耗散系数矩阵, 从而建立了介质的一阶速度应力方程. 采用交错网格高阶有限差分法及PML边界条件, 对xoz平面内的2.5维矢量波动方程进行了数值模拟. 结果表明,裂缝的极化角和方位角的存在都会导致横波分裂, 而在双层裂缝诱导TTI双孔隙介质模型的分界面上,又会产生转换波的分裂和横波的再分裂现象, 这就增加了波场的复杂性, 从而为进一步研究实际地球介质的地震波场传播特征奠定了基础.
