摘　　要：裂缝性油气藏是全球油气资源重要勘探领域。对于无井区域,以地震数据为基础的裂缝预测,是生产实践中解决裂缝空间展布难题最主要的手段。文章对地震属性裂缝预测方法进行了整理,阐述了叠前和叠后地震属性预测裂缝的方法,指出存在的问题和方法优缺点。最后应用各种地震属性裂缝预测方法到西部某区块,有一定的预测效果。未来五维地震方位各向异性分析将会是地震裂缝预测的方向。Fractured reservoirs are important exploration fields of global oil and gas resources.For the area without well,fracture prediction based on seismic data is the main method to solve the problem of fracture spatial distribution in production practice.In this paper,the seismic attribute fracture prediction methods are sorted out,the pre-stack and post-stack seismic attribute fracture prediction methods are expounded,and the existing problems and advantages and disadvantages of these methods are pointed out.Finally,various seismic attribute fracture prediction methods are applied to a certain block in the west,and certain prediction results are obtained.In the future,5D seismic azimuth-anisotropy analysis will be the direction of seismic fracture prediction.
