简介:为了深入研究准噶尔盆地碎屑岩储集层岩石微观孔隙结构与流体赋存关系,明确储集层油水比例及其流体在微观孔隙结构中的赋存状态,提高储集层流体性质解释评价符合率,在简述岩心显微荧光薄片数字化应用系统功能以及量化数据采集与处理的基础上,以该盆地25口井共90个试油层为统计分析对象,应用显微荧光量化数据,结合常规荧光描述,首先确定了碎屑岩储集层显微荧光解释评价标准;然后针对量化数据中的荧光发光面积和颜值与储集层流体性质的研究,建立了利用荧光发光面积与颜值划分不同储集层的解释评价图板。将该标准与图板相结合不但可实现准噶尔盆地碎屑岩储集层的有效解释评价,而且在一定程度上还可体现储集层是否具有工业开采价值。2016年在位于准噶尔盆地西北缘及其腹地的20余口井收到了较好的应用效果。
