description The utility model relates to the technical field of logging equipment, in particular to a high-temperature slim hole natural gamma-ray spectrum logger. The high-temperature slim hole natural gamma-ray spectrum logger comprises a shell and a logging circuit. The logging circuit comprises a probe tester, a signal amplifier, a processing circuit, a communication circuit and a power circuit. The shell is further internally provided with a vacuum bottle, and the probe tester, the signal amplifier, the communication circuit, the processing circuit and the power circuit are arranged in the vacuum bottle. The maximum outer diameter of the shell is not larger than 76 mm. Due to the fact that the logging circuit is arranged in the vacuum bottle, the high-temperature resisting performance of the logger can be effectively improved, and due to the fact that the maximum outer diameter of the logger is arranged to be not larger than 76 mm, the logger can be suitable for measuring drilling wells with small diameters.
