针对滨南油田油藏裂缝性储层的特点,以地震地质资料为主利用断裂增强滤波处理后的地震资料,提取了反映储层微裂缝的最优几何属性:曲率属性的线状特征,最大曲率与裂缝的密度有内在的联系,通过曲率的方位角研究裂缝的方向。通过岩心资料和成像测井与地震资料相结合分析裂缝空间展布规律。滨南油田潜山储集空间类型多、分布不均匀,裂缝、溶孔和溶洞发育,储集空间具有结构形态上的复杂性和空间变化的随机性。通过研究得到该区裂缝的方向主要是北东向,主要发育在大断层附近的构造高点,西北部沿断层走向有个裂缝不发育的条带,其他各层段储层的特征表现为一定的相似性。
Aiming at the characteristics of fractured reservoirs in Binnan Oilfield, taking seismic data as the main data, the optimal geometrical attributes reflecting microcracks in reservoirs are extracted. The linear features of curvature attributes are the largest The curvature is intrinsically linked to the density of the crack, and the direction of the crack is studied by the azimuth of the curvature. The distribution of fracture space was analyzed by combining core data and imaging logging with seismic data. There are many types of buried hill reservoirs in Binnan Oilfield, with uneven distribution, fractures, dissolved pores and karst caves. The storage space has the structural complexity and spatial randomness. The study shows that the direction of the fractures in this area is mainly north-east direction, which mainly develops in the structural high point near the large faults. In the northwest, there is a strip with undeveloped fractures along the faults, and the characteristics of the reservoirs in other layers are certain Similarity.
