摘　　要：经历多期勘探开发的密井网区其各期的井网测井条件存在着很大差异。利用不同条件下的测井资料进行地质解释会导致地质结论的不确定性;对多期勘探开发的测井资料统一进行标准化处理,同样会造成测井资料刻度误差。提出对密井网区采用分不同时期井网,用均值趋势面法进行测井资料标准化的方法,给出分期井网标准层测井响应均值趋势面分析方法。对大庆×区块按布井时间先后顺序的6个时期的井网704口井的声波时差采用标准层声波时差均值趋势面分析方法进行分期井网标准化,消除了非地质因素的影响,统一了全区声波时差的刻度标准。该方法应用效果较好,可为测井解释提供较准确的数据。In dense well pattern which has been data varies in different stages. When making data, the results often have multi-solutions. explorated and developed for a long time, the log geologic interpretations with different stage log Errors in calibration will also appear when normalizing different stage log data. Therefore, this paper proposes the idea that using trend surface analysis method to normalize the log data in different stages separately, and provides the effect analysis methods. In × block of Daqing oilfield, trend surface analysis method is used to normalize the acoustic time mean value of 704 wells at six different stages. The normalization shows that this method eliminates the non-geology factors and unifies the calibration standard of acoustic log data. The good application effect indicates that it can provide reliable data for welllog interpretation.
