摘　　要：合理的地层压力水平不仅可以使油井取得较高的采收率,而且能够降低注水开发的难度。通过静水柱压力法、低渗透油藏确定法、原油粘度确定法和物质平衡等方法,确定合理地层压力保持程度。注水井合理井底流动压力的确定是合理注水压力系统界限研究的重要内容之一,同时也是油藏注水开发设计的重要依据,在确定合理地层压力保持程度的基础上确定合理流压与合理注水压力。通过目前生产现状对比,评价目前注采压力系统,从而确保较高的采收率,降低注水开发的难度。Reasonable formation pressure level could not only make the oil well had a higher recovery,but also reduced the difficulty of water injection development. By hydrostatic pressure method,low permeability reservoir determination method,crude oil viscosity determination method and material balance method,the reasonable formation pressure maintenance level was determined. Determination of the reasonable bottom hole flowing pressure water injection was one of the important content of the reasonable injection pressure limit of the system,and was also important basis of water flooding design. The reasonable flow pressure and the reasonable water injection pressure were determined on the basisof determining the reasonable formation pressure maintenance level. The injection-production pressure system was evaluated through the current production status,so as to ensure a higher recovery,and reduce the difficulty of water injection development.
