Study On Comprehensive Development Sapu Formations In Nan1 Region Of Sazhong Development Area

South one area sapu reservoir after first encryption,secondary encryption adjustment,the phases of stage has good development effect,but with high water cut period into the development phase,some unfavorable factors which are influent development effect and production again,mainly show in certain areas,sedimentary unit of injection-production corresponding difference,the used reservoir's situation is bad,the water cut up fast and so on several aspects of the problem.Analysis the reason is that in the early part of the oil production in high aquifer and risk layers are all take measures to avoid shot of casing damage and influence,leading local area well horizons injection-production not perfect,sand body side becomes poor parts and clay sand between existing in the remaining oil,in order to improve the effect of oilfield development,we must tap the effective remaining oil.This paper discusses the south one area's necessity and feasibility to carry on the comprehensive governance,puts forward several methods of integrated management,analyzes the different deposition model of residual oil reservoir types,expounds the comprehensive utilization measures such as fill holes to mine the practice of remaining oil and effect.Notable achievements are aiming at the current blocks' problems,we had a reservoir fine research,3d geological modeling and residual oil numerical simulation analysis,and put on the numerical historical fitting of geological reserves,oil production,moisture content,stress,Understanding the law the distribution of remaining oil.Based on this,we based on the principle of."the deepening understanding reservoir,Recognize adjustment material,implement adjust the potential,optimized solution".confirm the comprehensive governance principles and schemes,the main measure is to fill holes,sand body perfect injection-production relation,improve water flooding control degree,implement conversion injection-production method and update old oil wells,and perfect injection-production relation local area,optimize injection well adjusted,shallow adjustable subdivision profile plan,control inefficient invalid circulation;optimize fracturing,stopping water solutions to improve oil well productivity.Through the implementation of the comprehensive governance to further improve the whole block development benefit.
