摘  要:在对姬塬地区延长组长8油藏综合研究的基础上,针对该区长8油层在时间、空间上的叠置关系,即“时间(层位)上跳、空间(平面)上跑”的特点,首次提出了姬塬地区长8油藏为“多层叠置的连续性油藏”的新概念,系统阐述了此类油藏的特点及形成条件.建立了多层叠置的连续成藏模式.并根据油层的叠置及连续情况将该模式分为3种类型.可为盆地类似油藏成藏研究提供借鉴。On the basis of integrated studies of Yanchang Formation Chang8 reservoirs in the Jiyuan area, in the light of characteristics of superimposition relationship in time and space of Chang8 reservoirs, that is, "jumping in time (on horizon) and running in space (on plane)", a new concept that Chang8 reservoirs in the Jiyuan are "multi-layer superimposed continuity of reservoirs" is proposed for the first time. Such kind of reservoirs" charac- teristics and forming conditions are systematically elaborated. A multi-layer stacked mode of continuous reser- voir-forming is established, and divided into three types according to the superimposition and continuous cir- cumstances of the reservoirs. It can afford lessons for reservoir-forming study of similar reservoirs in the basin.
