油田注水保持压力是确保油田长期稳产、提高油田开发效果的有效途径。高效的注水系统能够节约水资源、降低注水成本,对提高注水井储层注水效率技术的研究对油田开发具有重大意义。基于前人对井底完井与储层渗流的研究,本文提出了一种新的注水效率评价标准,对储层注水效率提高潜力合理评价,可以为储层选择针对性的改造措施提供了理论依据。
Oilfield water injection pressure is to ensure long-term stable production of oil and improve oilfield development effective way. Efficient water injection system can save water resources and reduce water injection cost. Research on technology of improving water injection efficiency of water injection wells is of great significance to oilfield development. Based on the previous researches on well completion and reservoir seepage, a new evaluation criterion of water injection efficiency is proposed in this paper. The reasonable evaluation of the potential for improving water injection efficiency of reservoirs can provide a theoretical basis for selecting appropriate measures for reservoir selection in accordance with.
