BEDROCK HYDROCARBON-BEARING CHARACTERISTICS AND POOL-FORMING CONDITIONS OF MAMUWUSU SAG IN BADAIN JARAN BASIN

摘要: 巴丹吉林盆地包含多个中生代凹陷,在其西北部麻木乌苏凹陷中首批钻探的两口井,均在前中生界基岩顶部钻遇良好油气显示,反映该区具有形成基岩油气藏的可能。分析认为,油气源来自侏罗系,不整合面和断层为主要运移通道,基岩具有相对较好的储集性,存在系列断块潜山型圈闭,油气分布显示出差异聚集的特点。因此,基岩油气藏是该区勘探的重要类型之一,扩大了油气勘探领域。Abstract: There are several Paleozoic sags in Badain Joran Basin.The first two wells drilled in Mamuwusu sag of the northwestern part of the basin were all found good oil/gas show,which indicated the possibility of forming bedrock oil/gas pools.The source rocks is Jurassic,the unconformity surfaces and faults are the dominant migration pathway,and the bedrock shows relative good storage ability.There are a series of block traps of buried hills in the area and distribution of oil and gas is different in different parts.The bedrock oil-gas pools may be the important exploration targets in the basin.
