摘要
迪北气藏位于库车坳陷东部迪北斜坡带中段,产层主要为侏罗系阿合组,次为阳霞组。该气藏储集层连片,源储紧贴呈"三明治"式叠置,有利于油气大面积高效率聚集;持续生排烃、持续强充注,有利于油气高丰度聚集;晚期调整、构造翘倾,导致气藏类型多样化,总体具有致密砂岩气藏特征。从烃源岩、储盖组合和构造等条件分析,库车坳陷东部侏罗系具有形成大面积致密砂岩气藏的地质条件,勘探潜力巨大。
Dibei gas reservoir is located in the center of Dibei slope, eastern Kuqa depression in Tarim basin. The main reservoir is the Jurassic Ahe formation, the secondary reservoir is the Jurassic Yangxia formation. Dibei gas reservoir belongs to a tight sandstone gas reservoir, which is characterized by tight reservoir, source-reservoir paragenesis, persistence accumulation and late adjustment. Considering the source rocks, the reservoir-cap assemblages and the structures, it is predicted that tight gas reservoir may exist widely in the Jurassic of the eastern Kuqa depression and could be of great potentials for gas exploration.
