摘要
对碳酸盐岩原生、次生流体包裹体的形成机理进行了分析，并分别在压力为100MPa、温度为400—300℃和350℃条件下，利用高温高压釜合成了碳酸盐岩原生、次生流体包裹体（NaCl-H2O），模拟了包裹体的形成过程，并利用激光拉曼光谱及显微测温技术对合成包裹体的成分、均一温度、盐度等参数进行了定量分析。结果表明，合成的原生、次生包裹体气相与空气成分相符，其均一温度分别为372．8℃和321．02℃，盐度分别为23．22％和19．54％．与实验前设定的条件相符，从而验证了合成包裹体的准确性，并为进一步分析包裹体相态奠定了基础。
The trapping mechanisms of the primary and secondary carbonate fluid inclusions were analyzed. Using the high temperature and high pressure vessel, the primary and secondary carbonate synthetic fluid inclusions （NaCl-H2O system） were formed under the same pressure of 100 MPa, the temperature from 400 ℃ to 300 ℃ and at 350 ℃ respectively. And the forming process of fluid inclusion was simulated. The composition, homogenization temperature and salinity of synthetic inclusions were qualitatively analyzed with Laser Roman spectra and microscopy freezing-heating stage. The composition of sample gas phase of the primary and secondary carbonate synthetic fluid inclusions agree with that of air, and the homogenization temperature of 372.8℃ and 321.02℃ and salinity of 23.22 % and 19.54 % all agree with the setting materials. It is indicated that quantitatively synthetic technology of fluid inclusions can supplemented each other very well, which laid the foundation of phase analysis for inclusion.
