拥有井下自动稳谱功能的自然伽马能谱测井仪

摘要

This paper introduces a kind of natural gamma ray spectral logging tools which can auto stable spectrum underground. The necessi-ty of instrument having the function is diss ussed and its stability spectrum principle,then an example is given to illustrate the instrument having certain superiority compare with the ordinary natural gamma ray spectrum logging instrument.%文章介绍了一种能够在井下进行自动稳谱的自然伽马能谱测井仪器。首先讨论了仪器拥有该功能的必要性，然后阐述了其稳谱原理，最后给出了一个实际例证，说明了该仪器与普通自然伽马能谱测井仪器对比拥有一定的优越性。
