摘要： 针对准噶尔盆地西北缘白云质灰岩裂缝型储集层,采用了小波尺度积边缘检测、广义希尔伯特变换、曲率分析等裂缝检测方法。经模型试验,以上方法具有较高的横向分辨能力和抗噪能力。3 种方法在乌夏断裂带风城组1 段进行了应用,通过与区域构造特征及井资料的相关分析,可看出这些方法在研究区应用效果良好。3 种方法配套使用,可相互映证和补充,提高检测结果的可靠性。

Abstract: Aiming at the dolomitic limestone fractured reservoir in the northwestern margin of Junggar basin, a series of the fractural detection methods are adopted, including the edge detection based on wavelet multiscale product, generalized Hilbert transform and curvature analysis. The model experiment shows that these methods are of high horizontal resolution and anti-noise ability. Applied to the first member of Fengcheng formation in Wuerhe-Xiazijie fault belt and by correlation analysis to regional structural characteristics and drilling/well data, it is indicated that these methods are applicable for this area. The three methods can be mutually confirmed and supplemented for the purpose of improving the reliability of the detection results.

Key words: Junggar basin, Wuerhe-Xiazijie fault belt, fracture detection, wavelet multiscale product, generalized Hilbert transform, curvature
