摘要(Abstract)：

为明确煤系薄层砂岩储层油气富集区展布,利用"地质主因分析—测井图版界定—地震定量预测"研究思路,以准噶尔盆地玛湖凹陷西斜坡Aih12井区八道湾组为例,分析研究区16口井183个岩心样品的粒度刻度(岩心—铸体薄片交互验证)—测井归位,比较不同粒度储层塑性岩屑体积分数及压实减孔效应,建立基于自然伽玛曲线的煤系砂岩储层定量评价图版并预测油气富集区。结果表明:粒度为煤系砂岩储层质量的关键控制因素,物性、含油性较优的高效储层主要为粒度较粗的(含砾)粗砂岩和(粗)中砂岩;根据砂岩界定标准(38关键词(KeyWords)：玛湖斜坡区;八道湾组;煤系砂岩储层;砂地比;高效储层;通油源断裂;评价图版;油气富集区
