Well Temperature, Gamma, and CCL Tool (TGC43C).pdf
Well Temperature, Gamma, and CCL Tool (TGC43C) primarily used for depth correction and leak detection.
This tool integrates the parameters of Well Temperature, Gamma, and CCL, it can be combined with other logging tools from our company for use in well logging.
Description：
. Principle of Natural Gamma Ray Measurement
The natural gamma ray section consists of a photomultiplier tube (PMT) and a sodium iodide (NaI) scintillation crystal.
The sensor detects gamma radiation emitted from the geological formations.
. Principle of Wellbore Temperature Measurement
The wellbore temperature measurement circuit employs a PT100 platinum resistance thermometer (PRT), which has a linear
relationship with ambient temperature.
. CCL Measurement Principle
The CCL consists of an inductive coil, magnetic steel, and an amplifier. The inductive coil is positioned between the magnetic steel
pieces. As the tool moves within the casing, the magnetic field strength within the coil changes correspondingly with the variation
of the magnetic flux from surrounding ferromagnetic objects, thereby generating an induced voltage.
Applications:
. The Correlation of cased hole logging curves between the casing and the wellbore.
. Depth control
. Lithology identification
. Leakage inspection using a high-resolution temperature logger
