摘　　要：论述了包裹体低温分析技术的原理以及进展。传统的流体包裹体低温分析技术是以显微冷冻测温测定无机盐体系为主,目前已发展到应用低温原位拉曼光谱技术对包裹体中的阳离子和阴离子进行定量-半定量分析。油气包裹体原位低温分析技术也取得了较大的突破,对不同成分油气包裹体低温下的相变过程取得了一定的认识,据此对油气包裹体进行分类,推测其主要成分,为油气包裹体计算提供基础参数。The principle and development of low-temperature analytical techniques for fluid inclusions were expounded. The traditional low-temperature analytical technology mainly focused on the measurement of inorganic salt using congealed microthermometry, but now it is developed to semi-quantitative and quantitative analysis of fluid inclusions using in situ cryogenic Raman spectrometry. The in situ cryogenic technology for oil and gas analysis also made a breakthrough in study on phase transition at low-temperature and the process of phase transition of oil and gas inclusions with different components at low-temperature were acquired. In the light of the process of phase transition, oil and gas inclusions were classified and the primary components of the inclusions could also be presumed. More component information of oil and gas inclusions could be obtained further when in situ cryogenic Raman spectrometry was used. Some basic parameters for quantitative study on oil and gas inclusions could be provided.
