Sonic Compressional ∆t Display

The digital acoustic logging tool is based on the theory of 2 transmitters and 4 receivers structureand GTS transmission mode.By measuring the slowness of longitudinal waves in the stratum to determine the total porosity of strata.Meanwhile, it can provide 3in CBL and 5in VDL for casing bond quality.All the electronic circuits are installed in the mandrel, thus instrument is lighter and length is shorter.
