本文应用测井资料、油层平百非均质分布、小层沉积相分析和数值模拟法，研究濮城油田南区沙二下１～５层系剩余油分布规律。指出，开采剩余油应采用完善注采井网，卡堵特高含水层，高渗透层注水，中低渗透层采油，平面小范围非均质变差部位综合调整挖潜，大范围变差部位钻加密井等方法。 In this paper, the distribution pattern of remaining oil in the first to fifth strata of Sha 2 under the south of Pucheng Oilfield is studied by using well logging data, non-homogeneous distribution of reservoirs, small sedimentary facies analysis and numerical simulation. It is pointed out that the residual oil recovery should adopt well injection and production well pattern, plugging extra-high aquifer, injection of high permeable layer, production of medium and low permeable layer, comprehensive adjustment and tapping potential of small-scale uneven heterogeneity areas, Well and other methods.
