摘　　要：C油田目前处于中高含水期,开发矛盾突出,表现在纵向超、亏压差异大、平面注采不均、单层水窜、稳控水难度大,迫切需要进行优化注水以改善油田开发效果。通过结合开发规律、生产阶段及井况进行产液量预测,考虑地层压力、水淹、地质因素进行分层配注实践,提出了优化注水建议及方法,在实践中进一步改善分层配注水平,最终提高水驱储量动用、改善注水开发效果。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 stabilizing 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 effectiveness of water injection development.
