| 摘 要： | 通过大量镜下薄片观察,南缘白垩系、侏罗系砂岩总体表现为低成分成熟度、低结构成熟度、较低胶结物含量和较弱溶蚀作用的"三低一弱"特征.西山窑组与八道湾组含煤系砂岩具塑性岩屑与高岭石含量较高,颗粒溶蚀压碎及成岩压实作用较强的"二高二强"特征.储层储集空间类型大致分为粒间孔、粒内孔、胶结物溶蚀及微孔隙等,以原生粒间孔为主.区域上,四棵树凹陷、霍玛吐呼背斜带是南缘侏罗—白垩系油气勘探有利区,齐古断褶带侏罗系由于断裂作用强烈,裂缝发育,对储层性质具改善作用.

| Abstract: | Based on the research of rock slices,the rocks of Cretaceous and Jurassic in the southern marlin of Junggar basin have the main character of low compositional maturity,low texture maturity,low cement content and weak corrosion.The sand of Xishanyao formation and Baodaowan formation,which are coal measure strata,are characterized by high plastic debris content,high kaolinite content and high pressolution diagenetic compaction.The main pore types of reservoir are intergranular pore,intragranular pore,cement emposieu and micropore.According to the reservoir characteristics and the distribution of high quality reservoir,Sikeshu sag and Malasi-hutubi anticline are favorable exploration area of Cretaceous and Jurassic.Secondary,it also need to pay more attention to the Jurassic in Qigu fold belt for the reservoir improvement by fracturing and split. |
