摘要:
依据野外露头、岩芯、测井及相关测试资料,对鄂尔多斯盆地苏里格南部地区上古生界中二叠统石盒子组盒8沉积期的沉积类型、沉积微相特征及沉积相对天然气成藏富集的影响进行了分析。结果表明:鄂尔多斯盆地苏里格南部地区盒8沉积期自北向南依次发育缓坡浅水辫状河三角洲和滨浅湖沉积相,亚相主要为三角洲平原、三角洲前缘、滨湖和浅湖,微相包括分流河道、分流间洼地、水下分流河道、水下天然堤、分流间湾、滨湖砂坝、滨湖泥湾和浅湖泥湾;各微相在空间上相互叠置,复合加积;各微相水动力条件的差异造成微相在沉积物成分和组构上各异,导致其成岩作用不同;分流河道和水下分流河道微相发育处密集形成相互叠置的大面积骨架砂体,构成区内主砂带,成为天然气优质储集层,是有利勘探相带;沉积相明显控制优质储集层的分布,进而影响着天然气的富集成藏。总之,水下分流河道和分流河道微相是砂岩优质储集层分布和发育的最有利相带,也是今后勘探开发的方向。
