摘　　要：从小微断层的成因入手,结合胜利、苏北一些油区的勘探开发实践,充分利用钻井、测井、地震、动态等资料,综合应用"静态4种技术、动态7项验证",较好地分辨出小微断层和地层相变的差别,识别出小微断层并对断层定向,实现了小微断层各类隐蔽特点的显性化。小微断层的显性描述在近年来的苏北盆地勘探开发中取得了显著成果,对指导同类型油田的开发工作有着重要意义。To identify and describe the small and micro faults which develop in the complex fault block oil- fields of eastern China. From the formation factors of the small and micro faults, and the exploration and de- velopment practice of Shengli and North Jiangsu Oilfields, dominant description of small and micro faults was carried out by the data like drilling, logging, seism, dynamic and so on. Meanwhile, four static techniques and seven dynamic verifications were comprehensively applied. It may distinguish well the difference between the small faults and strata facies-changes, and the orientation of the small faults. It has yielded notable results that the dominant description of small and micro faults in the exploration and development of North Jiangsu Ba- sin in recent years, and has important significance for the development of the similar oilfields.
