摘　　要：钻孔超声成像方法能精确地反映井壁的光滑情况,进而判断岩石的风化发育程度,确定风化层的厚度。阐述了钻孔超声成像的走时和振幅图像特征,给出了1个在香港地区的应用实例。The borehole ultrasonic imaging method can precisely reflect the smoothness of the borehole wall, and then judge the weathering degree of the rock and determine thickness of the weathering bed. This paper describes traveltime and amplitude image characteristics of borehole ultrasonic imaging, and gives an application example in Hong Kong area.

关 键 词：钻孔超声成像 岩石风化 声波走时 声波振幅
