摘　　要：库木库里盆地介于祁漫塔格山与东昆仑阿尔喀山之间,该盆地主要为第三系沉积,厚度大于7000m。盆地呈三角形,西端最宽处约255km,总面积约1.6×104km2。从盆地构造特征、沉积相、烃源岩以及储盖条件对盆地第三系石油地质条件进行了初步评价,并对盆地含油远景进行了基本评价。研究表明,盆地油气聚集的主要场所在中央隆起带两侧,其次为大向斜的北翼和南翼。鉴于此,按照油气富集的重要性,可将盆地含油气远景区划分为3个带,即北部油气聚集带、南部油气聚集带和碱土梁油气聚集带。Kumukuli Basin was situated between Qimantage Mountain and East Kunlun Aerojin Mountain.It was a Tertiary deposional basin with thickness about 7000m,it was a delta basin with the widest position about 255km and covered with a total area of 1.6×104km2.The Tertiary oil geologic condition was initially evaluated from the aspects of the basin structures,depositional facies,source rocks,reservoir and cap-rock conditions.Oil-bearing prospects of the basin were essentially evaluated.Results of the study show that hydrocarbon accumulation positions are on both sides of the central uplift belt,the next is on the north and south of megasyncline.On the basis of the importance of oil and gas enrichment,its oil-bearing prospective areas are divided into 3 zones,such as the northern oil and gas accumulation zone,the southern accumulation zone and Xiantuliang accumulation zone.
