摘　　要：运用数值模拟方法对低流度油田油层启动状况影响因素进行分析,结果表明,启动压力梯度、层间干扰、非均质性、井距、注水层段的划分、井网完善程度均会影响油层启动状况。分层注水对纵向非均质程度弱的油田改善油层启动状况效果不明显,同时提高注水量和产液量、高含水油井转注、油井酸化压裂均可有效提高油层启动状况,改善低流度油田开发效果。The paper analyzes the factors affecting the start-up of low mobility reservoirs by using numerical simulation.The analyses show that the start-up of low mobility reservoirs is influenced by start-up pressure gradient,interference between layers,heterogeneity,well space,layer separation of zonal injection of water and or well pattern.The improvement of start-up for vertically low heterogeneous reservoirs by zonal injection of water is not obvious.The increase in water injection volume and liquid production volume,conversion of oil wells into water injection wells for high water cut reservoirs and matrix acidification and fracturing can improve reservoir start-up,thus effectively improving the development efficiency of low mobility reservoirs.
