摘要(Abstract):
北乌斯丘尔特盆地是中亚地区油气资源丰富的盆地之一。根据北乌斯丘尔特盆地最新的数据资料,应用含油气系统综合分析方法,将盆地划分为8个成藏组合;以成藏组合为评价单元,利用统计法和类比法求取评价参数,采取蒙特卡洛法模拟计算盆地未来30年油气待发现可采资源量潜力。结果表明:北乌斯丘尔特盆地待发现石油、天然气和凝析油的可采资源量(均值)分别为13.147 4×10~7 t、1.547 2×10~(11) m~3、239.1×10~4 t,合计2.581 2×10~8 t油当量。最具潜力的含油气系统是滨里海—侏罗系含油气系统和中侏罗统—渐新统含油气系统;区域上,油气主要分布于北布扎奇隆起、库尔图克凹陷、切尔卡尔凹陷和苏多奇凹陷,表现为"西油东气";层系上,油气主要富集于中侏罗统和下白垩统。最有潜力的成藏组合为西部布扎奇侏罗系、西部布扎奇下白垩统和北乌斯丘尔特中侏罗统成藏组合。
