Research And Application Of Deep Profile Control And Flooding Technology For High Water-cut Oil Reservoirs In Dongdongpu, Jilin Province

In recent years,Nanpu onshore oilfield has entered the development stage of ultra-high water cut.Through the implementation of profile control and flooding technology,the oil field water-flooding coefficient has been improved and the water flooding development effect has been improved.However,with the increase of profile wheel,the dosage of medicine increased and the effect of profile control and oil displacement increased.Especially in the north shallow reservoir,through the implementation of large-scale transfer drive,prescription oil gradually decreased.And the deep oil displacement technology has gradually become one of the key technologies for the stable production of the Nanpu oilfield.The aim of this paper is to study the influencing factors of deep oil displacement and control in Nanpu oil field with high water cut and development,analyze the mechanism of deep flooding and displacement,and propose technical measures and measures to improve the effect of deep oil displacement and displacement,to improve the development effect of Jidong Oilfield Theoretical support.Through the indoor test,the system of the deep blockage and blocking agent is optimized,and the system is evaluated,the combination and the injection process are optimized.This paper provides the theoretical basis and technical countermeasures for the deep oil displacement of Jidong Nanbao high water cut oil reservoir by indoor material model and numerical simulation experiment,and directs deep deployment,optimization design and on-site implementation.
