| Abstract: | 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. |
