【摘要】：考虑到储层和地质构造的复杂多样性,为了突出储层结构及地质构造特征及其方向性,如储层的空间分布和内部的精细结构、断层和裂缝系统、褶皱等,在经典的高斯滤波方法基础上,推导了各向异性高斯迭代平滑滤波方法及其实现算法,同时建立各向异性地震体曲率分析方法,将两者联合应用,形成了地震资料的组合型方向体曲率分析方法。实际地震资料的处理结果表明,本文方法可在压制地震背景干扰的同时突出具体方向的地质异常信息。
[Abstract]:Taking into account the complex diversity of reservoirs and geological structures, in order to highlight the reservoir structure and geological structural characteristics and their directionality, such as the spatial distribution and internal fine structure of the reservoir, faults and fracture systems, folds, etc., Based on the classical Gao Si filtering method, the anisotropic Gao Si iterative smoothing filtering method and its realization algorithm are derived. At the same time, the anisotropic seismic volume curvature analysis method is established, and the two methods are applied in combination. A combined directional curvature analysis method for seismic data is developed. The processing results of the actual seismic data show that the method in this paper can suppress the interference of the seismic background and at the same time give prominence to the geological anomaly information in the specific direction.
