常用的测井资料标准化方法对单标准层进行分析,最后仅得到单一的乘因子或者加因子,导致标准化后得到的测井资料井间可对比性不好,储层参数建模的精度难以提高。考虑测井系列的一般线性刻度方法及其误差传播,本文尝试选取两个稳定分布的标准层。通过对该两个标准层采取趋势面校正处理,得到符合一般线性刻度方法的测井资料的线性校正公式。该方法在ST地区对48口井进行了测井资料标准化处理,校正效果得到明显改善。
The commonly used standardization method of well logging data to analyze a single standard layer, and finally only get a single factor or factor, resulting in well-logging data can not be compared well, and the accuracy of reservoir parameter modeling is difficult to improve . Considering the general linear scaling method of log series and its error propagation, this paper attempts to select two stably distributed standard layers. By adopting the trend surface correction processing for the two standard layers, a linear calibration formula of the well logging data which accords with the general linear scale method is obtained. This method standardized the logging data of 48 wells in ST area, and the correction effect was obviously improved.
