最近的一项技术，共聚焦扫描激光显微镜，可以精确测量油流体包裹体的气泡填充度（F-v）作为温度的函数[Pironon， J., Canals， M., Dubessy， J., Walgenwitz， F., Laplace-Builhe， C., 1998]。用共聚焦扫描激光显微镜对单个流体包裹体的体积重建。皮毛。[j].矿物学报，1999,16(1):1 - 4。这些数据与均质温度（T-h）的测量结果相结合，为我们表征单个烃流体包裹体提供了新的约束条件。为此，基于天然油的应用热力学，建立了一种新的建模工具，PIT（石油包裹体热力学），用于解释碳氢流体包裹体的体积（F-v）和微温度（T-h）测量结果。利用该软件，我们可以：(1)重建古温压油藏的圈闭条件；(2)模拟石油包裹体组成；(3)了解一组流体包裹体在各种捕获前或捕获后过程（包裹体拉伸、油混合、液/气分离、气浸油等）中的差异（F-v-T-h）。(C) 2000 Elsevier Science B.V.版权所有
A recent technique, the confocal scanning laser microscopy, allows for the accurate measuring of the bubble filling degree (F-v) of oil fluid inclusions as a function of the temperature [Pironon, J., Canals, M., Dubessy, J., Walgenwitz, F., Laplace-Builhe, C., 1998. Volumetric reconstruction of individual fluid inclusions by confocal scanning laser microscopy. Fur. J. Mineral. 10, 1143-1150]. These data, combined with measurements of homogenization temperature (T-h), give us new constraints for characterizing individually hydrocarbon fluid inclusions. For this purpose, a new modeling tool, PIT (Petroleum Inclusion Thermodynamic), based on applied thermodynamics of natural oils, has been constructed for interpreting volumetric (F-v) and microthermometric (T-h) measurements obtained on hydrocarbon fluid inclusions. The software allows us: (1) to reconstruct the paleo-thermobarometric trapping conditions of oils; (2) to model petroleum inclusion composition; and (3) to understand (F-v-T-h) differences among a population of fluid inclusions in terms of various pre- or post-trapping processes (inclusion stretching, oil mixing, liquid/vapor de-mixing, oil leaching by a gas, etc.).
