Abstract: The southeastern flank of Algin(Alkin) fault in the Chaidamu basin, along which Lake Gaskule, Lion Ditch, Brine Spring, Oil Spring and Xiaoliangshan are located, was the principal center of deposition of paleogene in the Chaidamu basin, well developed with source rocks. This is an area that should be given priority in exploration. The Yiliping depression in the middle of the basin and the Gansenquan fault-depression are favourable prospects for further exploration. Based on the differences in origin and morphology, the structural traps in the basin are classified into five types: contempraneous anticlines, faulted-folded structures, draping folds, bending folds and surface folds, of which contempraneous anticlines are most favourable for oil accumulation. A general appraisal is made of the three oil regions in the basin, with the Mangya depression, holding Tertiary deposits, being considered as the most promising.

摘要: 柴达木盆地沿阿尔金断裂带的东南侧,包括尕斯库勒湖、狮子沟、成水泉、油泉子和小梁山在内,是早第三纪柴达木盆地的主要沉积中心,生油层发育。是重点勘探的有利地区。位于盆地中部的一里坪凹陷和南部的甘森泉断陷是进一步勘探的有利地区。按成因及形态的不同把盆她的构造圈闭划分为同生背料、断褶构造、披盖褶曲、隆褶构造和表层褶皱五种圈闭类型。其中以同生背斜圈闭聚油条件最好。对盆地三大油、气区进行综合评价,其中茫崖拗陷第三系含油区是柴达木盆地今后可望找到大油、气田的有利地区。
