摘　　要：本文阐述了双相干相关法的基本原理 ,并将双相干相关法用于断层检测和落差估算。理论模型计算表明 ,用该方法检测断层准确 ,估算落差精度高 ,且具有一定的抗噪能力。作者还对基本双相干相关法进行了改进 ,用改进后的计算公式对实际地震资料进行了处理 ,结果表明 。The paper described the elementary principle of double coherent correlation method and its application in fault detection and throw evaluation,calculation of theoretic model shows that the method may have advantages of correct fault detection,high resolution of throw evaluation and a certain noise resistant ability. The authors have improved on the method and processed real seismic data with the improved calculation formula. The results show that the method is one of effective method for fault interpretation.
