流体包裹体在油藏地球化学研究中有着重要的应用价值。含油包裹体丰度(GOI)可以确定古油水界面, 包裹体均一化温度可以确定油气藏形成时间, 包裹体分子组成可以反演油藏的充注历史, 冰点可以确定地层水的演化及确定油藏储量。此外流体包裹体还可以确定油气藏的演化程度、油气运移通道及盆地异常压力。文中还提出了研究中存在的问题及努力的方向。

Fluid inclusion has important application in reservoir geochemistry. GOI (grain with oil inclusion) value, the homogeniation temperature and MCI (molecular composition of inclusion) can be used to determine the paleo-OWC (oil water contacts), the charging time and hydrocarbon charge history respectively. Freezing point can describe the evolution of strata water and the oil reserves. Besides, fluid inclusion also can be used to determine the evolution stage of reservoir, migration orientation, and abnormal pressure of basin. Some problems and research trend are also discussed.
