it is the main logging instrument of the CSU system , it is connected with TCC data transmission short sections to measure formation's conductivity in the CSU system . data communication is Passing by CCS three-bus interfaces between the DLT tools and the TCC , and DLT tools pass the well components datas by the way of digital data with the help of TCC ,then transmit it to the ground system for processing. During logging usually the DLT tools is with microspheres and gamma logging instrument for combinations .
The instrument is consists of electronic circuits, FPR electrode probe, the lower electrode and the insulating short section AH169 . Probe's FRP materials is imported from overseas which is usually be used in the logging instrument ,it is with good quality.
