Abstract: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.
Keywords:leaser frequency modulation absorption spectroscopy  Ratio of C13 /C12
