摘要
为查明准噶尔盆地西北缘车排子凸起南部石炭系油气成藏规律,对车排子凸起地质露头样品及CHH60井流体包裹体样品进行镜下观察和显微镜测温分析,样品在单偏下为浅棕黄色,荧光下呈明显浅黄、黄绿色;烃类包裹体在荧光及紫外光下呈淡蓝、绿色,有机质成熟度中等。均一温度测定对象均为烃类包裹体伴生的同期盐水包裹体及含烃盐水包裹体,按其相态,这些包裹体可分为单一液相包裹体、气液两相包裹体。其与烃类流体分布于3个温度段,即:三叠纪中晚期、早中白垩世及古近纪中晚期—新近纪早期。时间分别对应225~208 Ma、133~108 Ma和54~7 Ma。
In order to find out the southern uplift of Carboniferous hydrocarbon accumulation in the northwestern margin of the Junggar basin sub car row, the Chepaizi uplift geological outcrop samples and CHH60 fluid inclusion samples were analyzed under microscope and microscope measurement, single partial pale brown yellow, pale yellow, yellow green is obvious in fluorescence; hydrocarbon inclusions in blue and green fluorescence in the ultraviolet light, the maturity of organic medium. The homogenization temperature is determined by the simultaneous inclusion of salt inclusions and hydrocarbon containing brine inclusions in hydrocarbon inclusions. According to phase states, these inclusions can be divided into two categories： single fluid inclusions and gas-liquid two-phase inclusions. The temperature distribution along with hydrocarbon fluid activities is in three temperature stages, espectively： middle Late Triassic, early Middle Cretaceous, and late middle Paleogene to early Neogenecorresponding to 225-208 Ma, 133-108 Ma and 54-7 Ma r.
