江汉石油管理局电测站实验研究的井壁声波测井方法,除了能记录探头在贴靠井壁时的声波时差曲线以外,还记录了与井剖面介质对声波能量吸收有关的“传输系数”。这对用声波幅度方法划分岩性、研究井壁附近声场分布打开了一条新路,同时也带来一些需要讨论的问题。本文仅对“地层声波传输系数”测井方法提出一些讨论意见。
In addition to recording the acoustic time-difference curve of the probe when it is close to the borehole wall, the well-bore acoustic logging method experimentally researched by Jianghan Petroleum Administration Electric Station also records the “transmission coefficient” related to the energy absorption of acoustic wave in the well profile media. . This opens up a new path for the division of lithology by using the acoustic amplitude method and the study of sound field distribution near the borehole. At the same time, it also brings up some issues to be discussed. This article only makes some comments on the “stratigraphic acoustic transmission coefficient” logging method.
