摘　　要：AS油田天然微裂缝较为发育,开发过程中压裂产生的人工裂缝对油田开发影响较大,制约着开发技术政策的制定及实施效果。在分析裂缝分布规律的基础上,利用试井技术对测试资料进行解释和评价,将解释成果和其他生产资料相结合并建立了WY区块裂缝分级标准。研究表明,通过上述方法能够了解不同级别裂缝对注水开发效果的影响,从而有利于提高WY区块的采收率并确保稳产的进行。Natural micro fractures of AS Oilfield are very development,artificial fractures generated in the development have great impact on oilfield development,restrict the development of technology policy and the formulation and implementation of the effect.On the basis of the fracture distribution,well testing technology is used to interpret and evaluate the test data,the interpretation of results is combined with other production materials to establish fractures grading standards of Block WY.It recognizes that different levels of fractures on waterflooding effect can help improve oil recovery and ensure stable production of Block WY.
