| 摘 要： | 综合利用岩石薄片、扫描电镜及X-射线衍射等测试手段对准噶尔盆地哈山地区侏罗系八道湾组储集层成岩演化特征进行研究.侏罗系八道湾组储集层储集性能既受沉积环境的控制,同时也受成岩作用的影响.压实作用、胶结作用是主要的破坏性成岩作用,不同的沉积岩石相的成岩作用略有差异,八道湾组总体埋深较浅,压实作用弱-中等,保留了大量的原生孔隙,为后期油气大面积的侧向运移提供了良好的物质基础.溶解作用为主要的建设性成岩作用,长石、碳酸盐岩胶结物的溶蚀是湿地扇扇中辫状河道砂岩相形成深部"甜点带"的主要原因.

| Abstract: | Based on rock thin section,scanning electron microscopy and X-ray diffraction,the diagenetic evolutionof the reservoir of Jurassic Badaowan Formation in Hashan area was studied. The reservoir performance is controlledby both deposition and diagenesis. Compaction and cementation is the main destructive diagenesis,which is typicalin glutenite of the braided channel facies in middle humid fan;and dissolution is the main constructive diagenesis,which is typical of feldspar and debris dissolution in sandstone of the braided channel facies in middle humid fan.The physical properties and oiliness of the transporting layer in glutenite is closely related to diagenetic evolution,which controls oil and gas migration directly. Overall,the sandstone reservoir of the braided channel facies inmiddle humid fan in Hashan area is of the best oil capacity and is the future exploration target. |
