五十年代中期以来,超声检测技术越来越广泛地应用于地质勘探,为地球物理探测提供了新的方法和参数。起初是使用超声波声速测井,六十年代初又使用了声幅测井,到1967年开始使用声幅扫描测井(亦称超声成像测井或声波井下电视测井)。从而使一维的声速或声幅曲线发展到二维的声幅图像。这样不仅可以了解井孔特性随深度的变化,而且可以探测井
Since the mid-1950s, ultrasonic detection technology has been applied to geological exploration more and more widely, providing new methods and parameters for geophysical exploration. Ultrasonic sound velocity logging was used initially. In the early 1960s, acoustic amplitude logging was also used. By 1967, amplitude-sweep logging (also known as ultrasonic imaging logging or acoustic downhole TV logging) was started. So that one-dimensional sound velocity or amplitude curve developed to two-dimensional sound image. This will not only allow you to understand wellbore properties as a function of depth, but will also detect wells
