| 摘 要： | 应用于煤田、金属矿和非金属矿及工程地质等勘探的非油气γ能谱测井仪，其设计与应用于油气田勘探的γ能谱测井仪是不同的。针对我国非油气γ能谱测井仪研究未有突破性进展的现实，在充分比较国内外非油气γ能谱测井仪几种研制方案的基础上，提出了一种测井信号沿长电缆以电流脉冲模拟方式传输的方案，并对此开展了试验研究。试验结果表明取得了较满意的成果，可为小型化、轻便型的非油气放射性γ能谱测井仪的研制提供一种新的途径。

| Abstract: | Compared with spectral gamma-ray tool applied to exploration for oil-gas field, the design of non-oil spectral gamma-ray tool is different, which is applied to such exploration as coal field, metal ore or non-metal ore, and engineering geology, etc. This paper puts forward a method of spectral gamma-ray logging signals transmission via a long cable in form of analogue, and some experiments have been made out. The results of the experiment show that signals transmission via a long cable in form of analogue is a new method for designing spectral gamma-ray logging tool. |

| Keywords: | non-oil spectral gamma-ray logging tool radiation pulse transmission via a long cable |
