基于Hausdorff距离的测井曲线尖峰深度校正

Peak Depth Correction of Logging Curves Based on Hausdorff Distance

提出了一种基于Hausdorff距离的测井曲线尖峰深度校正方法.先利用极值和变量数列分析法选取合理的尖峰,应用双向Hausdorff距离准确选取相似曲线段位置,再应用单向Hausdorff距离确定最佳匹配尖峰,进而计算尖峰深度校正值.实验表明,该方法能实现快速、精准的尖峰深度校正,为油田的油气层开发提供可靠准确的数据资料.

An effective method of peak depth correction based on the Hausdorff distance is put forward in this paper. The automatic identification of logging curve peak made up the blank of automated processing of logging curve peak depth correction. In this method, the reasonable peak is selected by using the extremum and variable sequence analysis method, and the position of similar curve segment is selected according to the bidirectional Hausdorff distance, then the best matching peak is defined through computing the unidirectional Hausdorff distance. Finally, the peak depth correction of logging curves is computed. The experimental results demonstrate that the method of peak depth correction has better speed and high accuracy, and it provides reliable and accurate data for petroleum reservoir development.
