摘要
对测井中子管而言，耐高温、长寿命、高稳定性、小型化是其不断追求的质量指标。为此，研制工作已在实验室里取得了１５０℃高温下中子管连续工作１５０ｈ以上的实测结果。在整个实验过程中，中子管的产额标准差保持在±１％之内。随后月余时间的多次测试证实了中子管的各项性能指标均未发生变化。文章描述了有关实验技术和测试结果。
As for the neutron tube for logging,high temperature,long life,high
stability and miniaturization are its quality norms to be pursued continuously.The tube
has been tested in the lab under 150℃ for 150 consecutive hours.In the process of the
whole test,the standard yield error of the tube keeps within the range of ±1%.In more
than one month after the test,the tube has been tested again and the results prove that
the properties of the tube remain unchanged.Described herein are experiment techniques
and the test results about the tube.
