摘要：

东濮凹陷兰聊断裂带是燕山期以来形成的张性断裂带,西邻生油深凹,东邻鲁西隆起。沿带发育大量鼻状构造、古潜山和水下扇。其下盘(为主)及上盘均有含油气圈闭。含油气圈闭的类型有:下降盘基底抬升形成的断鼻构造、滑塌砾岩封堵的断鼻构造;上升盘的生物礁、地层-构造圈闭和低部位的古潜山。

Abstract:

Lanliao fault belt on the east margin of Puyang Depression is a tensile fault belt formed in Yenshan Epoch.The belt,being 140 km long and 6-8 km wide,is situated close to a deep-depressed oil-generating belt in the west and the Luxi Uplift in the east.Most of the Mesozoic and Upper Paleozoic are absent in its upper wall,but sediments of various geological times are well preserved on its foot wall.The 3rd member of the Neogene Sha-hejie Formation is the main source rock.Along the fault belt,a lot of nose structures and subaqueous fans developed on the footwall,and buried-hills and bioherms on the upperwall.Hydrocarbon could be found on both walls.The main types of hydrocarbon traps in the study area are faulted-nose structure formed by basement uplift of the footwall,fault-nose resulted from the slope of slumping conglomerate on steep slope,bioherm,structural-stratigraphic trap and buried hill.
