2¾" Dual-transmitter-three-receiver Acoustic Wave-Variable DensityCombination Logging Tools
The inspection of well cementation.
Only a single-conductor cable is needed to connect the surface system with downhole tools.
The temperature compensator in the Gamma Ray Tool can compensate the drift caused by the temperature on Gamma ray detector.
Two transmitters and three receivers can effectively overcome the problem of tool deviation and the influence of the liquid in the well.
