流体包裹体对地下热液活动及油气运移具有较好的示踪作用 ,尽管在确定最高古地温及其时间方面存在一些不确定性。为了评价均一温度的可靠性 ,该文首先用物质平衡法推导出了包体测温的数学模型。模型表明 ,体积较大的包体测温数据较准确。对莺琼盆地包体测温数据系统分析研究表明 ,该区包体的均一温度主要受来自深部 30 0 0～ 40 0 0米的热液活动控制。流体包裹体发育与超压层埋深、烃源岩生排烃作用而引起的热液活动和油气运移具有密切关系。该结论与该区镜质体反射率观测数据及井温资料较为吻合
Fluid inclusions have a good tracing effect on the hydrothermal activity and hydrocarbon migration in the underground, although there are some uncertainties in determining the maximum paleotemperature and its time. In order to evaluate the reliability of uniform temperature, the article first used the material balance method to deduce the mathematical model of temperature measurement of inclusions. The model shows that the larger body temperature measurement data more accurate. The analysis of the temperature data in the Baojiao basin in the Ying-Qiong Basin shows that the homogenization temperature of the Baomeng Formation in this area is mainly controlled by the hydrothermal activity from the depth of 300 ~ 400 meters. The development of fluid inclusions is closely related to the hydrothermal activity and hydrocarbon migration caused by the overburden depth and hydrocarbon generation and expulsion. The conclusion is consistent with the vitrinite reflectance data and well temperature data
