一、引言超声波成象钻孔电视是人们早已熟识的一种手段.自它问世以来,一直受到地学界及其他领域的科研人员的重视和信赖。它之所以具有很强的生命力,主要是因为它具有测量速度快、精度高、方便灵活、随测即显等特点,当场即可直观地看到孔壁360°的展开柱状图象。通过对图象照片的简单分析或计算处理,便可获得地层产状、钻孔几何形态和其 I. INTRODUCTION Ultrasound Imaging Drilling Television is a well-known means by people and since its publication, it has been valued and trusted by scientific community and other researchers. The reason why it has a strong vitality, mainly because it has the measurement speed, high precision, convenient and flexible, with the measured significant features such as spot on the spot you can visually see the cylindrical wall of 360 ° unfolded column image. By simple analysis or calculation of the image photographs, we can obtain the formation formation, the drilling geometry and its
