| 摘 要： | 裂缝检测与图像分析中的边缘检测有许多相似之处，因此，能够借助某些边缘检测理论并结合实际地震资料形成有效的裂缝检测方法。作者基于小波多尺度边缘检测理论，结合地震波场对裂缝的多尺度特性，提出了碳酸岩裂缝预测的多尺度边缘检测方法。方法的主要思想是：利用小波变换械的局部极值，检测出三维地震记录裂缝点特征位置，并通过调整模值在图像中的灰度，自动识别裂缝发育区的范围。

| Abstract: | Fracture detection is similar with boundary detection in image analysis. Therefore, using boundary detection theory and real seismic data can form effective fracture detection way. In this paper, based on wavelet multi scale boundary detection theory and seismic wave field' s multi scale characteristics for fracture, we propose a new method of multi scale boundary detection in carbonate fracture prediction. This main ideal of method take local extremum of wavelet transform modulo will lead up to detect characteristic fracture point location of 3D seismogram, and automatically to determine fracture edge region by adjusting the grayscale of modulo value in image. Real application shows that this method can detailly describe the local characteristics of carbonate fracture which's detectied result coincides with real drilling data, and also shows that this method is a valid approach for carbonate fracture detection. |
