In this paper, the standardization of natural gas composition analysis by Laser Raman Spectroscopy was studied, and the feasibility of Standardization was discussed. When using Laser Raman spectroscopy, multiple components can be measured simultaneously without separating every component, so it can save analyzing time, improve real-time effect and realize fast analysis. In addition, the technical status and developing trend for natural gas analytical method by Laser Raman through domestic and international standardized investigation were studied, and data of natural gas analysis experiments by Laser Raman were accumulated. The results show that Laser Raman spectrum will be a powerful tool for real time rapid access to gas quality data in natural gas logging, wells station, gas quality analysis of gas gathering station and natural gas purification process control due to the advantages of fast test (10 seconds), continuous record as well as simple operation. It is suggested to work on standards of natural gas analysis method by Laser-Raman to test CO2, N2, H2S, CH4, C2H6 and C3H8, and the testing ranges are CH4 is from 75% to 99.9%, C2H6 0.005%～20%, C3H8 0.005%～10%, H2S 0.001 5%～10%, N2 0.02%～10% and CO2 from 0.01% to 10%(mole fractions), offering service in the upstream area for natural gas composition monitoring to improve exploration and development.
