摘　　要：长庆油田是典型的低渗透、特低渗透油田 ,注水能力是影响水驱开发油藏开发效果不容忽视的重要因素之一。从地层堵塞的原因入手 ,综合考虑影响地层堵塞的各种因素 ,重点从影响注水水质因素。Changqing oilfield is a typical low permeability or extremely low permeability oilfield. Water injection capacity is one of the important factors affecting waterflooding response. The factors of formation plugging are comprehensively analyzed, including the influence factor of injected water quality, the compatibility and sensitivity of injected water and formation water.
