The Research On A New System Of Composite Intelligent Control Plugging With Control Water Displace Oil And Mechanism

This article mainly aims at rfactured-vuggy reservoir characteirstics, and carry out asystem of intelligent profile control and a system of multiple ifmctional plugging control withwaterflood. research. From the factors on intelligent plugging agent intelligent gel of pluggingmechanism, functional polymer selecting, concentration, iemperature, salinity, additives etcand and the evaluation of plugging agent in the porous medium,we get狂kind of system ofsotf viscoelastic gel or gel group.Then We study the influence of the gel of the pluggingmechanism, concentration, temperature, salinity, configuration water and pH value change，wediscuss resistance to erosion and sealing performance.From these aspects，get狂gel system ofgood oil displacement eiffciency and conformance eiffciency.Two systems can be used aloneand also can be used in combination, it can be applied in fractured reservoir. Being a pilottest,the system of composite plugging control and watefrloodl has good sealing property, andhas obtained the remarkable effect of oil increase precipitation.
