通过测试分析获取流体包裹体资料，为进一步研究古地温梯度、油气组成及成因、油气运移充注期次、成藏及含油气盆地的热史重建等方面提供数据支持。以塔河油田主体区奥陶系流体包裹体为研究对象，通过显微镜观察其形态、大小、颜色、分布、相态、荧光现象，结合包裹体均一温度和盐度等测试分析，认为主体区为多期油气充注成藏，先后经历了加里东中晚期-海西早期的先充注后破坏，海西晚期以破坏或改造为主，印支-燕山期少量缓慢充注及改造，喜山早期和喜山晚期的两次调整充注。加里东中晚期-海西早期和喜山期的3次充注在包裹体均一温度资料上有较好响应。包裹体盐度变化趋势表明，油气多源自主体区南部的满加尔坳陷，具向北运移成藏特点。

The inclusion tests and analyses have became an increasingly mature technique,which applied in various field of geology and put emphasis on by sedimentologist and petroleum exploration geologist.By the test analysis of flu-id inclusions we got datum,which provided data support for the analyses of paleogeothermal gradient,oil and gas com-position,oil and gas migration filling periods,accumulation and thermal history reconstruction in petroliferous basin. This article took fluid inclusion of Ordovician in main area as research object,based on microscopic observation such as form,size,colour,distribution,phase and phenomenon of fluorescence,combined with analysis of homogenization tem-perature and salinity in fluid inclusion. We considered that the main area was multistage of filling and migration. From the middle-late Caledonian to early Hercynian oil and gas was destroyed after filling.Destruction or reform play an im-portant role in late Hercynian.Perhaps a few oil and gas was slowly filled and reformed in Indosinian-Yanshanian. Hima-layan period had twice filling.Only middle-late Caledonian-early Hercynian period filling and twice filling in Himalayan can be well related to datum of homogenization temperature in fluid inclusion.While variation tendency of salinity in flu-id inclusion showed that the oil and gas source came from north of northern Manjar depression,migrated northward for accumulation.
