摘　　要：巴音都兰西南次洼位于二连盆地马尼特凹陷中部,下白垩统巴彦花群发育一套内陆河湖相碎屑岩沉积,腾格尔组和阿尔善组烃源岩十分发育,岩性以深灰、灰黑色泥岩、页岩为主。有机碳含量为0.26~1.63,氯仿沥青A含量为0.01~0.57,总烃含量为40~3132。有机质类型以Ⅱ_1-Ⅱ_2为主,Tmax平均为433~445℃,热演化程度处于低成熟的生油阶段。生油率40mg/g,利用氯仿沥青A计算,总资源量为920×10~4t,表明该地区资源背景较差。The southwest subsag in Dulan,Dulan,is located in the middle of the manate depression in the two Lian basin.The lower Cretaceous Bayan flower group develops a set of inland river lacustrine clastic rocks.The source rocks of the Teng Ko Erh and ALSHAN formations are very well developed,and the lithology is dominated by deep ash,gray and black mudstone and shale.The content of organic carbon is 0.26 to 1.63,chloroform A content is 0.01 to 0.57,and total hydrocarbon content is 40~3132.The type of organic matter is mainly 1-II 2,and the average Tmax is 433~445 C,and the degree of thermal evolution is in the low mature oil generating stage.The oil generating rate is 40mg/g,and the total amount of resources calculated by chloroform asphalt A is 920*104t,indicating that the resource background in this area is poor.
