Fine Anatomy Of Monosandbody And Remaining Oil Analys Of Shasan Formation Of Shen84 Edge Block

After many years of Water-flooding development, Shen84 block has entered the stage of“high water content”. However, because of the new exploration blocks found increasingly difficult and the urgent demand of oil energy, depends on the old oilfield’s stable-production and enhanced recovery factor to obtain the biggest economic benefits, requirement of reservoir study more detailed. In order to better carry out the depth of the old oilfield development and exploration work, Comprehensive and fully recognize reservoir macro and micro features of reservoir, after water injection development changes, oil-gas-water dynamic distribution characteristics and remaining oil distribution regulation etc. Geological research combined with oilfield development integration mode, not only provides a guidance for oilfield development measures exploration, also to improve the ultimate recovery in the process of oilfield development research work.In this paper, Through logging interpretation and the core technology such as 3 d geological modeling method, deeply develop of Shen84 block edge’s potential area of wide spacing micros- structure analysis, Sedimentary microfacies analysis, horizon optimization,fine description of fine geologic research and single sand body contrast. Clear remaining oil distribution regulation and horizon developent potential, for the horizontal well development of thin sand body provides a good theoretical basis and technical support.Fine Anatomy of Monosandbody is the basis of fine geologic research. Based on the sand body distribution, sedimentary microfacies, semicrostructure and reservoir distribution,comprehensive analysis and description of single sand body. Clear the remaining oil distribution types and characteristics. Combined with the Reservoir using situation to forecast the area of remaining oil potential, provides the possibility for oil field to digging of residual oil.
