摘要:
从测试原理、计算方法两方面对近年来新出现的“声呐渗流检测或测井”技术提出了质疑，指出了这一技术存在的严重问题，认为声呐技术是不能用来进行渗流测试的。
Abstract:In this paper, the “sonar percolation detection or logging” technology, which has emerged recently, is questioned from the aspects of test principle and calculation method, and the serious problems of this technology are pointed out. It is considered that sonar technology can not be used for seepage testing.
