摘要： 针对准噶尔盆地中部Ⅰ区块低含油饱和度油藏,从构造、储集层和成藏过程3 方面对其成藏机理进行了系统研究,定量、半定量分析了油藏调整、油气重新运聚、油水分异的充分性及低渗透储集层油水过渡带高度和隔夹层对油水分布的影响。认为研究区低含油饱和度油藏是以油气藏调整为前提,以低幅度构造、低渗透储集层为背景条件,在储集层隔夹层突破压力、低渗透毛细管压力、油气充注强度等多种因素影响下形成的。

Abstract: A reservoir with low oil saturation is of complex geologic structures and hydrocarbon accumulation modes. Research of its genesis can help to evaluate reservoir quality and regional exploration situation. In view of such a reservoir in No.1 area in central Junggar basin, the systematic studies of its structure, reservoir rock and hydrocarbon accumulation process are conducted for understanding of its reservoir-forming mechanism, including quantitative and semi-quantitative analyses of the reservoir adjustment, oil-gas re-migration/accumulation, oil/water differentiation sufficiency and the effects of oil/water transition zone height, barrier and interbed of the low permeability reservoir on its oil-water distribution. It is recognized that the reservoir in this area is formed on the premise of oilgas reservoir adjustment and setting conditions of low-amplitude structure and low permeability reservoir rocks with many factors of breakthrough pressure of its barrier and interbed, capillary pressure and oil-gas charging sufficiency, etc.

Key words: Junggar basin, low oil-saturated reservoir, low permeability, abnormal pressure, structure adjustment
