摘　　要：首先讨论了互相关函数的计算方法及互相关函数的意义 ,提取了 3种特征参数和 5个统计量 ,并说明了这些特征参数所包含的地震信息及其意义 ;然后分析了互相关函数及统计特征参数曲线在数据分析中的应用 ,列举了在原始数据分析、剩余静校正分析、检验相位校正效果和判断埋置检波器极性是否翻转等几方面的应用情况。不同地区实际资料的应用结果表明 ,互相关特征参数分析法是地震数据处理中一种有效的分析工具。Cross correlation function was used to analyze the procedure and quality control of prestack seismic data processing in this paper. Firstly, we discussed the computing method of cross correlation function and its significance,extracted three characteristic parameters and five statistics, and at the same time elucidate their meaning and Suchas the seismic information involved in these parameters. Then we illustratd applications of the cross correlation function and characteristic parameters in analysis and initial data,residual statics,phase correction results,and judgment of reversal of receiver polarity, etc. It is concluded from an investigation on real seismic data in various areas that characteristic parameter analysis is an effective analysis tool in seismic data processing.
