SLT acoustic logging tool
SLT tool is one main logging tool of CSU series .
The instrument uses a high-power magnetostrictive transmitter transducer, high-temperature attenuation is small; using metal bellows and Acoustic Transmission. cover, to improve the efficiency of sound transmission , reduce direct wave coupling, and the penetration of H2S.
The instrument can be used directly in CSU system, 520 system.
The instrument can also be connected with long-spaced sonic probe.
