摘要: 准噶尔盆地乌尔禾地区丰富的油砂资源主要来源于玛纳斯湖凹陷二叠系烃源岩,这套烃源岩中生成的油气沿着该地区发育的断裂和不整合面向上运聚成藏,并在地表附近由于水洗、氧化、生物降解等作用,原油中的轻质组分不断消耗,最终形成油砂矿。该地区油砂的分布与断裂和不整合面紧密相关,油砂矿体沿断裂和不整合面分布。

Abstract: The Wuerhe area in Junggar basin has abundant resources of oil sand, mainly originated from source rocks of Permian in Manas lake sag. The oil and gas from it migrate/accumulate upward along the developed fractures and the uncomfortable surfaces, and form the reservoirs. Because of the water-washing, oxidation and biodegradation near the surface, the light components of the crude oil consumed continually, finally forming the oil sand deposits. The distribution of oil sand in this area is closely related with fractures/faults and unconformities, hence the oil sand body's distribution occurs along the fractures and the unconformities.

Key words: Wuerhe, oil sand, fracture, fault, unconformity, crude densification
