摘　　要：储层裂缝分布规律、方向和规模是影响裂缝性油藏开发的重要因素，裂缝分布规律、方向等因素的确定也是油藏描述中的一项重要工作。特别是对于低渗油藏，裂缝是油流通道，同时注水开发时也可以是水流通道，对油水井的部署非常重要。为了认识油藏裂缝方向及规模，探讨了应用生产动态数据对裂缝进行识别的相关方法，主要包括注水井动态判别法、生产井动态判别法和油水井之间关联判别法等。采用这些方法能初步判断储层的裂缝分布特征，为低渗油藏开发取得好的开发效果提供了技术支持。实际应用表明，效果较好。The distribution rule, direction and scale of reservoir fractures are not only important factors for development of fractured reservoir, but also key factors for reservoir description. In low permeability reservoirs, fractures are stream path during waterflooding, with significance for deployment of producers and injectors. This paper discusses how to identify fractures using production performance data, mainly including dynamic discrimination method for injector and producer, as well as correlation discrimination method for injector and producer. With these methods, the features of fracture distribution can be preliminarily ascertained, providing technical support for development of low permeability reservoir. Field application shows good effect of the study result.
