摘要：

塔里木盆地东南区可划分为塔东南坳陷和塔东南隆起2个构造单元。塔东南坳陷侏罗纪为一箕状断陷,形成民丰且末若羌3个沉积沉降中心,具南断北超的特点,阿尔金山为主要物源区,塔东南隆起为次要物源区。油气主要富集在侏罗系储层中,煤系及深湖相泥岩是生油岩的主要发育层位,储层具低孔低渗、成分成熟度和结构成熟度均低的特征,溶孔和裂隙为主要储集空间。综合分析后认为,塔东南坳陷具备形成中、小油气田的条件,应以寻找背斜断块圈闭为主,罗布庄隆起与北民丰隆起上的风化壳、民丰环形构造和安迪尔环形构造、于田普鲁与且末其格勒克向盆地的第一排构造带山前低台阶带为有利勘探区块。

Abstract:

The structures in the southeast of Tarim Basin could be divided into two structural units such as southeast depression and southeast uplift.The depression was a dust-pan shape faulted depression in Jurassic,including Minfeng,Qiemo and Ruoqiang three depocenters and subsidence centers.The depression faulted in the south part but overlapped in the north,with Altun Mountains as the primary provenance and then the uplift being secondary.The main reservoirs are Jurassic System,coal measures and deep lake mudstone are the main source beds.It is considered that the depression is favourable for the formation of small- and mid-size oil and gas fields,oil and gas exploration should focus on anticline fault blook traps;the weathered crusts of Luobuzhuang and north Minfeng Uplifts,Minfeng and Andir circular structural belts,-Qigelek pidemont low terraced structural belt are target areas for oil and gas exploration.

Key words: southeast Tarim Depression, Jurassic System, sedimentary environment, oil generating condition, reservoir property, reservoir origin, oil-gas prospects
