摘要

摘要: 从鄂尔多斯盆地三叠系延长组6个油砂样品的抽提物中,通过色谱-质谱(GC-MS)分析,首次检测出一系列C_0-5芴-9-酮化合物和苯并芴-9-酮化合物,它们是芴和苯并芴在储集层中发生氧化-还原反应的产物。这个过程是由于在晚成岩A期,陆表暴露时期,伴随着含氧和细菌的大气淡水的渗入,在延长组储集层中的铝硅酸盐矿物参与下,油砂中的烷基芴和苯并芴在碱性成岩环境下氧化的结果。

Abstract: Six oil sand samples were collected from the sandstone reservoirs of Yanchang Formation in the northwestern areas of the Ordos Basin,Northwest China.Oil sand extracts were analyzed by GC-MS.A series of alkylated fluorenones have been detected.They are products of oxidation-reduction reaction of fluorene and benzo-fluorene in reservoir.This process can be considered as the result of that during the time of subaerial exposure in the later diagenetic stage A,the fluorene and benzo-fluorene in oil sand are oxidized to fouow the permeating of meteoric water with bacteria and oxygen under the alkali-diagenetic enviornment and participation of the sialicate in Yanchang Formation.
