致密储层裂缝发育带的地震识别及相应策略

致密岩层中的裂缝和孔洞系统对油气赋存和运移起重要作用。但由于裂缝的多尺度性和地震资料分辨率的有限性，使得利用地震资料识别和检测致密储层裂缝系统变得很困难。本文探讨了这些问题，并指出如果采用适当的技术和策略，则有可能确定储层中裂缝发育带的空间分布。主要技术有；三维地震多尺度边缘检测技术的应用，地震数值模拟和检测结果的相关分析以及应用地震、地质、测井、钻井等多源信息的综合解释等。

Seismic identification of fracture-developed zone of dense reservoir and relative strategy

The fractures and caves system in dense formation plays an important role in oil/gas accumulation and migration.It is difficult to use seismic data to identify and detect the fractures system in dense reservoir because of multi-scale of fracture and limitation of resolution of seismic data.In this paper,we discussed these issues and pointed out that the spatial distribution of fracture-developed zone in reservoir can be determined if proper techniques and strategy are used.The techniques used mainly include:application of 3D seismic multi-scale margin detection technique,correlation analysis of seismic numeric modeling and detection results and using multi-source information such as seismic,geologic,logging and drilling for integrative interpretation.
