摘要
塔里木盆地的古生代原型盆地是叠置于前寒武纪结晶变质岩系之上的克拉道盆地．盆地内发育了不同类型的古隆起，它们是：塔中稳定古隆起、塔北残余的古隆起、塔东残余古隆起、巴楚活动古隆起和塔南活动古隆起．这些不同类型的古隆起，具有不同的构造演化历史和不同的油气藏形成条件．古隆起蕴藏着丰富的油气资源，预测资源量占盆地内总资源量的近一半．在塔里木克拉通盆地寻找大中型油气田，首要的勘探目标是塔中稳定古隆起及其北斜直线和塔北残余古隆起及其南北斜坡，前者的勘探目的层是石炭系、奥陶系、志留系和泥盆系；后者的勘探目的层是石炭系、奥陶系、寒武系、震旦系、三叠系、侏罗系、白垩系和第三系。第二勘探目标是巴楚活动古隆起及其南斜坡，塔东残余古隆起及其西斜直线和塔南活动古隆起及其西南斜坡。它们的主要勘探目的层是石炭系、侏罗系、奥陶系、志留系和第三系．
The palaeozoic prototype basin in Talimu is a craton basin piling up on precambrain crystalline metomorphic rock system.Different kinds of palaeohighs developed in the basin.They are Tazhong stable palaeohigh,Tabei residual palaeohigh,Tadong residual palaeohigh,Bachu active palaeohigh and T;anan active palaeohigh.They have different tectonic evolution histories and forming conditions for oil and gas reservoir.A lot of oil and gas is accumulated in these palaeohighs.It is estimated that their reserve is about half of the total reserve in the basin.To look for large and midium sized fields in the basin,the first exploration objectives should be Tazhong stable palaeohigh and its northern slope,Tabei residual palaeohigh and its northsouthern slope.The exploration objective strata of the former are Carboniferous,Ordovician,Silurian and Devonian systems,and those of the latter are Carboniferous,Ordovician,Cambrain,Sinian,Triassic,Jurassic,Crataceous and Tertiary systems.The second exploration Objectives are Bachu active palaeohigh and its southern slope,Tadong residual palaeohigh and its western slope,Tanan active palaeohigh and its southwestern slope.Their major exploration objective strata are Carboniferous,jurassic,Ordovician,Silurian and Tertiary systems.
