摘要:
针对南堡潜山碳酸盐岩油藏开发中后期剩余油分布认识不清的问题,从油藏实际出发,在双重介质储层地质建模的基础上,开展剩余油分布规律研究,确定剩余油分布模式,明确开发调整及提高采收率潜力,制定下步开发对策。研究结果表明,油藏基质系统剩余油富集,裂缝系统存在5种剩余油分布模式,分别为油层顶部富集型、井间滞留型、断层根部型、井网未控制区剩余油和物性差区剩余油。结合生产实践,针对不同的剩余油分布模式,分别提出复合氮气驱、调堵+氮气驱、完善井网顶部注氮气、大型酸压为主的挖潜对策和方向。研究成果为同类油藏的剩余油挖潜提供了思路和方法借鉴。
Abstract:
It is not well understood the remaining oil distribution in Nanpu buried hill carbonate reservoir at the middle and later stages of development. From the practical situation of oil reservoir,based on dual porosity reservoir geological modeling, the distributing rules of the remaining oil were studied to determine the remaining oil distribution patterns, make clear development adjustment and improve potential tapping, and develop the next-step development strategy. The achievements indicated that the remaining oil was accumulated in reservoir matrix system and it was put forward 5 kinds of the remaining oil distribution patterns in the fracture system, which are in the top of the reservoir, inter-well residence type, fault root type, remaining oil in the uncontrolled area of well net and remaining oil in poor property area.Combined with production practices, potential tapping measures and directions of compound nitrogen flooding, plugging and nitrogen flooding, perfect well net and top nitrogen injection, and large-scale acid fracturing are respectively proposed for different remaining oil distribution patterns, which could provide new thinking and reference measures for digging remaining oil in similar oil reservoirs.
