This paper proposed a crosshole tomographic method using precise ray-tracing in complex medium,The block model is described by local linear function of mode for cell velocity distribution,and precise inversion formula corresponding with forward calculation was given. It was not only avoid the disagreement between model parameters and inversion parameters but also soluted dismatch problem on forward and inversion in traditional curve ray-tracing. In order to make forward calculation fast, an improved shot-method was used in two-point problem. The numerical and practical application results show that the proposed precise ray method is fast, stable, reliable and applicable.

提出了一种基于岩石物理模型与混合优化算法同时反演孔隙度和饱和度的新方法。将孔隙度和饱和度的取值范围加入反演过程作为约束,能提高反演的稳定性和精度。基于地震纵、横波速度反演结果,直接得到油藏参数值。该方法也可以推广到直接利用地震振幅属性来进行反演。分析了不同属性组合对孔隙度和饱和度反演结果的影响。模型计算结果表明,该方法具有精度高、稳定性好等优点,同时易于推广到多种岩石物理模型、多地震属性组合与多参数定量反演中。
