【摘要】：文章對鄂爾多斯盆地隴東地區(qū)上古生界盒8段流體包裹體的賦存礦物類型、形態(tài)、均一溫度、成分等參數(shù)進行研究,結(jié)合盆地埋藏史探討研究區(qū)儲層內(nèi)流體包裹體捕獲事件及烴類充注史。實驗表明,包裹體賦存于3種礦物類型,有三種形態(tài),研究區(qū)包裹體均一溫度位于90~170℃,峰值在100~130℃,測定其組分為CH_4和CO_2。隴東地區(qū)在晚侏羅世—早白堊世主要經(jīng)過3次流體包裹體捕獲事件。綜合均一溫度及埋藏史,認為該研究區(qū)主要有一期天然氣充注,充注成藏時期主要是J3-K1,即晚侏羅世—早白堊世。
[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 擄170 鈩，
