摘要
本文从探区生油、储集、圈闭及油气运移等油气藏形成基本条件入手,结合构造发育史,分析了主要油气藏的成因。提出生油凹陷、较大储集岩体、较好的盖层及继承性发育的背斜是控制大油气藏分布的主要因素。较大的断块油气藏存在可能性很小,因该区断裂活动时间长且晚,对油气主要起通道作用。下一步应以寻找地层岩性油气藏为主。
From the basic conditions referring to the formation of oil-gas pools inclu- ding origin of oil-gas,their migration and accumulation in the eastern part of Junggar basin combined with the history of tectonic development in this area,this article analyses the formation of the main oil-gas pools.The author suggests that the main factors controlling the distribution of large oil-gas pools should be existence of oil-gas source depression,larger reservoir sandbodies, better caprocks and successively developed anticlines.The possibility of disco- vering larger fault-block oil-gas pools is fairly low,because the faults was active in a fairly long geological age,and being fairly new,thus faults mainly play a role of passageway for oil-gas migration.For further exploration the stratigraphic oil-gas pools should be emphasized.
