C Oilfield is currently in the medium to high water cut stage,with prominent development contradictions,manifested in large vertical overpressure and pressure loss differences,uneven single layer water channeling in plane injection and production,and great difficulty in stabili-zing and controlling water.It is urgent to optimize water injection to improve the development effect of the oilfield.This time,the main focus is on predicting liquid production based on development laws,production stages,and well conditions.Stratified injection practice is carried out considering formation pressure,water flooding,and geological factors.Suggestions and methods for optimizing water injection are proposed to further improve the level of layered injection in practice,ultimately increasing the utilization of water drive storage and improving the effective-ness of water injection development.
