摘　　要：针对南海西部涠西南地区注水井启动压力规律性较差这一问题,从该区注水井注水动态入手,对注水井吸水指数、启动压力、试井解释等资料进行综合分析,提出注水附加压力的概念,为注水井吸水能力的研究提供新的方法,该方法在涠西南地区开发方案制定、开发效果预测以及注水设施配置中均有非常重要的意义。In view of poor regularity of start-up pressure of water injection wells in Weixinan area in the west of South China Sea,and starting with water injection performance of water injection wells,this paper comprehensively analyzes the water absorption index,start-up pressure and well test interpretation of water injection wells in this area.This paper puts forward the concept of additional water injection pressure,which provides a new method for the study of water injection capacity of water injection wells.This method has significance meaning in the formulation of development plan,prediction of development effect and allocation of water injection facilities in Weixinan area.
