摘　　要：低序级小断层的识别在三维地震资料精细构造解释以及储层特征研究、剩余油分布研究中都具有极为重要的作用。对三维地震体数据运用基于倾角控制的构造导向滤波方法进行处理,并结合三维地震相干体等技术对低序级小断层进行解释,取得了良好效果,在胜利油田某区块的实际应用中得到了证明。这两种技术方法的综合应用能在一定程度上帮助地震解释人员快速识别低序级小断层,并能指导断层平面组合方案的正确性。The recognition of minor faults is very important in the structure interpretation of 3D seismic data,reservoir description and the distribution of remaining oil. The method that after the 3D seismic data has been processed by structure oriented filtering based on angle control,combining with the seismic coherence technique to explain the minor faults,it has achieved good results and been proved in practical application in Shengli Oilfield.The comprehensive application of these two techniques can help the seismic interpretation personnel to identify the minor faults quickly and to guide the fault plane combination correctly.
