摘要: 准噶尔盆地西北缘经历了多期构造活动,为油砂的形成创造了有利的条件,在该区多处发现油砂露头,因此,深入、系统地开展该地区油砂特征和成藏模式分析,对该地区下一步的油砂勘探有着重要的指导意义。以准噶尔盆地西北缘红山嘴地区油砂为例,采用物理和化学实验的方法,分析了该区油砂的物理特征及油砂含油率特征,初步计算出该区油砂油的地质资源量;通过对地质、构造活动等方面的研究和分析,探讨了研究区油砂的富集模式,发现该区砂体空间展布和物性较好,为有利的油气储集空间,多期构造活动为油砂的形成创造了有利的条件;不整合面和断裂体系非常发育,对该区油气的运移起着控制作用,这两个主控因素对该区油砂的形成起着决定性的作用。

Abstract:

The northwest margin of Junggar Basin underwent multiplestage tectonic movement,which provides favorable conditions for the formation of oil sands.The

northwestern margin of Junggar Basin experienced the multiphase tectonic movement,which provided the favorable condition for oil sand forming.Oil sand outcrop appears in

many places in this area.So an indepth study on oil sand characteristics and reservoirforming model is important to guide the oil sand exploration in this

area.Taking the oil sand in Hongshanzui area,northwestern margin of Junggar Basin as example,the reserach analyzes physical characteristics and oil yield characteristics

of oil sands with physical and chemical test,the oil from the oil sand geologic reserves in Hongshanzui area is elementarily calculated.In addition,the reservoir

forming model of oil sands is disccused by studying geological settings and structure movement,and the favorable sandbody distribution and physical characteristics

illuminated.Unconformity surfaces and faults system are wideranging in this area,which controls the oil and gas migration.The two master factors above are crucial

influence on oil sands forming in this area.

Key words: oil sand, characteristics, total resources, reservoirforming model, Junggar Basin
