摘　　要：裂缝型储层是一种典型的各向异性介质，其研究基础是地下介质的各向异性理论，进行裂缝型储层描述的关键是获得地层中裂缝的密度、走向等属性。伊通地堑基岩裂缝发育、基岩储层埋藏深度大，具有很强的非均质性和各向异性，目前进行储层裂缝预测的主要方法是基于裂缝成因和地下介质各向异性。在伊通地堑SY区块基岩储层应用方位频率属性预测裂缝的效果表明，该方法具有一定的应用前景。The fractured reservoir is one kind of typical anisotropic medium, and its theoretical researches are based on the anisotropic theory of subsurface media. The keys of the fractured reservoir characterization are focused on the collection of the following attributes： fracture density, strike and the others. Yitong Graben basement is characterized by well-developed fractures, deep buried reservoirs and stronger heterogeneity and anisotropy. At present, the main methods of the fracture prediction are generally based on the fracture genesis and subsurface media＇anisotropy. The effects of the bedrock reservoir fracture prediction by azimuth frequency attribute in SY Block of Yitong Grahen show that there are a certain practical prospects for the method.
