摘要
本文利用激光频率调制吸收光谱技术,测量了钻井气样中甲烷^(13)C/^(12)C同位素比。该方法不仅精度较高,而且具有检测限低、光谱分辨率高、样品处理简单和快速测量等优点,可以为油气勘探提供一种有效的辅助手段。
In this paper, we determined the ratio of C13 /C12 of methane in slurry gas from oil wells by the method of laser frequency modulation absorption spectroscopy that has many advantages such as high precision, high spectroscopic resolution and rapidly and simply dealing with samples. This technique provided us with a subsidiary method for oil-gas source exploration. The method of laser frequency modulation absorption spectroscopy is based on the method of laser frequency absorption spectroscopy and is more accurate. And this method can be expanded to apply to others aspects easily. We only need change other appropriate laser and select right absorption peak, then we can determined the ration and concentration of diverse gases.
