摘要
该文通过对西北地区中生代含油气系统的油气充注条件、油气运移和捕集方式及空间分布规律的综合分析 ,进行了含油气系统的成因分类 ,划分了 2 4个中生代含油气系统 ,并根据系统类型、油气资源量、圈闭类型及目的层埋深、油气藏及油气显示等多种综合因素进行了含油气系统的初步评价 ,指出塔西南侏罗系含油气系统、准东南复合含油气系统、柴北缘侏罗系含油气系统应作为油气勘探的战略选区重点。
By comprehensive analysis on the petroleum charging conditions,migration and entrapment patterns,and space distribution rules of the Mesozoic petroleum systems in Northwest China,they are classified by geneses into 24 petroleum systems. Based on system types,hydrocarbon resource amount,trap styles,target stratum depth,petroleum accumulation and shows as well as the other factors,the petroleum systems are evaluated preliminarily. It is suggested that the Jurassic petroleum system in the southwest of the Tarim Basin,the composite petroleum system in the guasi southeast of China and the Jurassic petroleum system in the northern edge of the Qaidam Basin should be taken as emphases for the strategic area selection of petroleum exploration.
