| 摘 要： | 以马海构造东南斜坡为例,从油源、储盖组合、圈闭等方面对柴达木盆地北缘马海以东地区地层油气藏进行了评价.研究结果表明,虽然该区地层圈闭落实,顶、底板具有较好的封堵条件,储盖组合良好,但是由于尕丘凹陷烃源岩发育较差,厚度小且分布局限,制约了该区圈闭的有效性,因而难以成藏.综合评价认为,该区今后地层圈闭目标的重点应转向马海构造西缘和北缘油气运移通道上的有利油气捕获部位. |

| Abstract: | Taking southeast slope of Mahai Structure as an example,strati-graphic hydrocarbon reservoirs in the eastern Mahai area of the northern margin of Qaidam Basin were evaluated from oil source,reservoir-seal combinations and traps etc.The results show that this area has good stratigraphic trap condition,preferable sealing condition at roof and footwall,and favorable reservoir-seal combinations.But the source rocks in Gaqiu Depression developed poorly with thin and limited distribution,which restrict the signif... |
