摘　　要：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。A study of remaining oil distribution is an efficient method for adjusting development scheme when oil field is in it's middle-later development stage. Now a days, the method of studying remaining oil distribution in the world include' heterogeneous geologic conceptual model, reservoir engineering, Coring, log data interpretation, production testing and so on. An attempt has been given in this paper by a combination of log data, lateral distribution reservoir heterogeneity, sublayer sedimentary factes and reservoir simulation, so that distribution of remaining oil in southern area E2s12 reservoir is studied. It demonstrates that the remaining oil will be recovered by perfeCt of injection-production pattern, blockage of high water bearing formation, injection into highly permeable part and production at less permeable part... etc.. It suggests that a comprehensive adjusting development scheme can be effective when the less permeable part is limited, while infill drilling is necessary when a relatively large area of lower permeability is occured.
