对石油包裹体研究和应用的几点认识

本文总结了对石油包裹体研究和应用的几点认识,包括流体包裹体岩相分析、显微温度分析、油包裹体丰度统计和原始样品采集及制备。强调流体包裹体岩相分析是直观而有效的分析技术,其结果可以提供油气是否运移、运移期次、相对早晚及每一期相对数量和油气大致特征等资料,也是其他有关包裹体研究的基础。显微温度测试必须以油气包裹体鉴定为基础,单纯应用均一温度划分油气运移期次是不合适的。油包裹体丰度是确定古油藏的重要参数,统计结果受多种因素影响。石油包裹体分析是研究性较强的方法,研究人员参与到分析鉴定工作中方能取得较好的研究成果。

An Overview on Petroleum Inclusion Research and Application

This paper provides an overview on some aspects of the petroleum-inclusion research and application,including fluid-inclusion petrography,microthermometry,petroleum inclusion abundance,and the collection and preparation of samples.It is stressed that the fluid-inclusion petrographical analysis is a direct and effective technique for studying petroleum accumulation,as it can provides many information,such as the petroleum migration,the migration stages,paragenesis,contributions of petroleum accumulation in various stages,and general characters of petroleum.The microthermometry of inclusions should be carried out on those meaningful inclusions determined through the fluid-inclusion petrography.It is not appropriate to classify the stages of petroleum migration only by applying homogenization temperatures of various inclusions.Petroleum inclusion abundance(GOI)is an important parameter for locating the petroleum reservoirs,though it is affected by many factors.The good results of the petroleum fluid-inclusion analysis only can be obtained when it was undertaken by research people,because it is an comprehensive research technique.
