【摘要】：文章对鄂尔多斯盆地陇东地区上古生界盒8段流体包裹体的赋存矿物类型、形态、均一温度、成分等参数进行研究,结合盆地埋藏史探讨研究区储层内流体包裹体捕获事件及烃类充注史。实验表明,包裹体赋存于3种矿物类型,有三种形态,研究区包裹体均一温度位于90~170℃,峰值在100~130℃,测定其组分为CH_4和CO_2。陇东地区在晚侏罗世—早白垩世主要经过3次流体包裹体捕获事件。综合均一温度及埋藏史,认为该研究区主要有一期天然气充注,充注成藏时期主要是J3-K1,即晚侏罗世—早白垩世。
[Abstract]:In this paper, the occurrence mineral types, morphology, homogenization temperature and composition of fluid inclusions in member 8 of Upper Paleogene in Longdong area of Ordos Basin are studied. Combined with the buried history of the basin, the fluid inclusion capture events and hydrocarbon filling history in the reservoir of the study area are discussed. The experimental results show that the inclusions occur in three mineral types and have three forms. The homogenization temperature of inclusions in the study area is 90 掳170 鈩，
