油田注水开发后期提升采油率的技术措施研究

Study on the technical measures to improve oil recovery in the late stage of oilfield water injection development

为了达到油田注水开发后期提升采油率的目标,本次研究主要是对影响采油率的因素进行分析,提出油田注水开发后期提升采油率的技术措施,为推动我国油田产业的进一步发展奠定基础。研究表明:在油田注水开发后期阶段,地层中的原油储量不断降低,地质因素以及技术因素会对采油率产生重要影响,因此,需要采取改良技术支持、强化环境分析、调整注采规模、优化注采方案以及注重效果评价等多种措施,使采油率可以得到一定的提升。

In order to achieve the goal of increasing the oil recovery rate in the later stage of oilfield water injection development,this study mainly analyzes the factors that affect the oil recovery rate,puts forward technical measures to improve the oil recovery rate in the later stage of oilfield water injection development,and lays a foundation for promoting the further development of China’s oilfield industry.The research shows that in the later stage of oilfield water injection development,the crude oil reserves in the formation are continuously decreasing,and geological and technical factors will have an important impact on the oil recovery rate.Therefore,it is necessary to take various types of measures,such as improving technical support,strengthening environmental analysis,adjusting the injection production scale,optimizing the injection production plan,and paying attention to the effect evaluation,to improve the oil recovery rate to a certain extent.
