通过比较具有趋势的克里格法与趋势面分析法的基本理论及其在测井资料数据标准化中的应用效果 ,认为 :可用具有趋势的克里格法取代趋势面分析进行测井资料的数据标准化。该方法由于考虑了地质变量的空间结构而优于趋势面分析法 ,且利用低次趋势面建立的变量的趋势面较利用高次趋势面分析得到的变量的趋势面容易进行地质解释。当数据点较多时 ,由于可更准确地获得变差函数 ,即捕捉更多结构信息 ,可使标准化效果更好。利用该方法进行测井资料数据标准化时 ,应重视对变差函数的确定。因此 ,提出应利用具有趋势的克里格法进行测井资料的数据标准化。图 5参 7(邹冬平摘 )
By comparing the tendency theory of Kriging and trend surface analysis and its application in data standardization of logging data, it is considered that the Kriging method with tendency instead of trend surface analysis can be used to log well data standardization. The method is better than the trend surface analysis method because of taking the spatial structure of the geological variables into account, and the trend surface of the variables established by the low order trend surface is easier to be geologically interpreted than the trend surface of the variable obtained from the high order trend surface analysis. When there are many data points, the standardization effect can be better because the variogram can be obtained more accurately, ie capturing more structural information. When using this method to standardize logging data, attention should be paid to the determination of the variogram. Therefore, it is proposed that the data of the well logging data should be standardized by using the trendy Kriging method. Figure 5 Reference 7 (Zou Dongping pick)
