多井测井资料的标准化处理方法——以M油田为例

Research on standardized processing method of multi-well logging data--by taking M oilfield as an example

多井测井资料标准化是多井测井解释中一项重要的基础工作,其主要目的是消除由测井仪器性能、刻度、操作等不一致所造成的系统误差,提高多井间资料的可对比性以及多井测井解释精度。以M油田自然伽马曲线资料为例,通过频率直方图法、均值校正法、趋势面分析法三种标准化方法,对测井数据进行了标准化处理。结果表明,三种方法在该区应用效果良好,测井曲线资料一致性得到改善,其中,频率直方图法和均值校正法在岩性和岩相较为稳定的条件下效果较好,趋势面分析法更符合地质规律,三种方法为多井测井资料标准化提供了借鉴。

The normalization of multi-well logging data is an important and fundamental work in multi-well logging interpretation.Its main purpose is to eliminate the systematic error caused by the inconsistency of logging tool performance,calibration and operation,and improve the comparability of multi well data and the accuracy of multi well logging interpretation.Through the study of frequency histogram method,mean correction method and trend surface analysis method,by taking the natural gamma curve data of M oilfield as an example,the logging data are standardized.The application effect of the three methods is good,and the consistency of curve data is improved,which provides reference for multi-well logging data standardization.
