The Research and Application of the Integrated Technology of Layered Water Injection and Profile Control
layered water injection and profile control are the leading technology to reduce the contradiction between layers and realize effective water injection and improve the development effect.With a water distributor it can realize that the integration completion of layered water injection and profile control.However,there are some risks with a small distributor channel,such as the large shear of the profile control agent,the blockage of bulk particles,and the tubing deposition of the returned profile control agent,which affect the effect of the profile control and water injection.Aiming at the existing technical problems,we deduced the mathematical model of the key tool profile control channel affecting the profile control agent apparent viscosity,developed a special profile control tool and switch matching with the injection process measurement and finally have formed anti-spit,low-shear integrated technology of layered water injection and profile control.A total of 9 wells were implemented,and the construction success rate was 100%.After profile control,the water injection starting pressure increased by an average of 3.4mpa,and the water content of the beneficial well was reduced by an average of 6%.Field application shows that the integrated technology of layered water injection and profile control can solve the problem of high viscosity loss rate and easy to return of the profile control agent,realize the safe and effective integration operation of layered water injection and profile control.
