- 摘要:
单个流体包裹体原位成分分析方法具有原位、微区、无损的特点,可以避免群体流体包裹体成分分析方法所导致的不同期次包裹体成分混杂的问题,是地质流体研究的有效手段。显微激光拉曼光谱法和显微傅里叶变换红外光谱法是两种常用的单个流体包裹体原位成分分析方法,从这两种方法的实验原理入手,初步探讨了两者的测试数据及地质应用。研究认为:上述两种方法可有效应用于分析成矿过程流体性质、识别含油气盆地油气演化过程、恢复成矿/成藏压力、判断油气成熟度等方面,具有广泛的应用前景。
In-situ composition analytical method of single fluid inclusion has the characteristics of in-situ, micro-area and non-destructive, which makes it an effective measure for geological fluid research. Compared with population composition analytical method, this method can avoid the mixed result of different period inclusions. Microscopic laser Raman spectra method and microscopic Fourier transform infrared spectroscopy method are two frequently used in-situ composition analytical methods of single fluid inclusion. This research introduced the experimental principles of these two methods, and discussed their test data and geological applications. The results show that the above two methods can be used to analyze the fluid properties of metallogenic processes, identify oil and gas evolution processes in oil and gas basins, restore formation/reservoir pressure, judge oil and gas maturity, etc. In conclusion, microscopic laser Raman spectra method and microscopic Fourier transform infrared spectroscopy method both enjoy wide application prospect.
