| 摘 要： | 石油包裹体的气液比是热力学模拟的敏感性参数，应用石油包裹体热力学模拟方法可以获得古油气充注时的压力，通过石油包裹体二维平面分析和三维形态重构，可以获取石油包裹体的气液比。实例研究证明，在一定的石油包裹体形态范围内，通过二维平面分析和三维形态重构获取的石油包裹体气液比与共聚焦激光-荧光扫描显微镜所测得的气液比的相对误差可以控制在±10%内。在缺少共聚焦激光-荧光扫描显微镜条件下，石油包裹体二维平面分析和三维形态重构方法比目估测量法能更准确地计算石油包裹体气液比，可以满足石油包裹体捕获压力模拟的精度要求。

| Abstract: | Paleopressure can be obtained by oil inclusion thermodynamics modeling, and ratio of vapor to liquid phase volume of oil inclusion is a sensitive parameter in this modeling, which can be got by 2D plane analysis and 3D shape reconfiguration of petroleum inclusions.The case study shows that within a certain oil conclusions shape, this ratio obtained by 2D plane analysis and 3D shape reconfiguration has relative error within ±10%, compared with the ratio given by confocal laser scanning?fluorescence scanning microscopy (CLFSM). WithoutCLFSM, the 2D plane analysis and 3D shape reconfiguration method is better than ocular estimation measurement method in calculation of the ratio, and can meet the accurate requirement for trapping pressure modeling of petroleum inclusions |
