库车坳陷秋南—亚肯地区构造特征与油气聚集
|
摘要
秋南-亚肯地区横跨库车前陆冲断带的前锋带和前缘外围带,油气地质条件良好,但构造变形复杂。综合应用地表露头、地震剖面和钻井等资料,根据构造-地层组合及变形特点,划分了上部(新近系库车组至第四系)、中部(下白垩统至新近系吉迪克组)和下部(基底至下白垩统亚格列木组)三个构造变形层。该区自上新世库车组沉积以来至少经历了两期挤压构造变形,造成不同构造变形层和不同构造样式的垂向叠置,形成了受多滑脱层控制的分层差异变形构造。结合油气成藏条件和已钻井分析,指出构造分层差异变形对该区油气纵向分布具有重要影响,油源断裂的沟通是油气成藏的主控因素,中部和下部构造变形层勘探前景较好。
Qiunan- Yaken area is across front zone of the foreland thrust- folded belt and the front peripheral belt,with good oil and gas geological conditions and complicated tectonic deformation.In comprehensive application of outcrops,seismic profiles and drilling data,on the basis of structural-stratigraphic combination and deformation characteristics,three tectonic deformation layers have been divided,namely the upper part(from Neogene Kuqa formation to Quaternary),the middle part(from lower Cretaceous to Neogene Jidike formation) and lower part(from basement to lower Cretaceous Yageliemu formation).Since Pliocene Kuqa formation sedimentation,at least two phases of compressive tectonic deformation have been undergone in this area,which led to different structural deformation layers and vertical stacked structure of different styles,and formed differential structural deformation controlled by multiple detachment layers.In combination with hydrocarbon accumulation conditions and drilled well analysis,the differential structural deformation is pointed to plays an important role in vertical hydrocarbon distribution of this area,the main controlling factor of hydrocarbon accumulation is the connection of oil- migrating faults,and the middle and lower parts of tectonic deformation layers are of better exploration prospects.
