    摘要:

    摘要:海拉尔盆地贝尔断陷中的变质岩潜山油藏规模大,产量高。断裂系统复杂,断层展布方向大致为北东东向,断面宽度大、断距横向变化快。变质岩储层在纵向上可分为:风化破碎带,裂缝、溶孔、溶洞发育带和致密带。油藏成藏规律受烃源岩供烃能力及与储层接触关系、储层自身的储油能力、断层及不整合面垂向、侧向运移油气能力控制。形成了以油气沿断裂和不整合面组合侧向运移的布达特群顶面风化壳聚集成藏模式和油气沿断裂垂向运移的布达特群内部裂缝破碎带聚集成藏的内幕油气藏模式。

    Abstract:

    Abstract: Metamorphic rock burial hill reservoir of Bell rift in Hailaer Basin, with large scale reservoir and high output, has complex fault system. The fault throughgoing direction roughly is NEE direction, and has wide fault section and lateral quickly changed fault displacement. Through the analysis of the core, debris, electric curve and seismic cross section, this paper confirms that metamorphic rock reservoir can be divided in the vertical: weathered fracture zone, crack and corroded hollow and cave development belt, and tight zone. Accumulation is controlled by hydrocarbon ability of source rock, contacting relationship of source rock and reservoir, oil storage ability of reservoir, and vertical and lateral oil-gas migration of fault and unconformity surface. And formed top surface weathering crust accumulation pattern which the oil and gas is lateral migration along the unconformity surface, and inside reservoir pattern of crack broken zone accumulation which oil and gas has the vertical migration along fault.
