摘要 塔河油田奥陶系油藏主要为特稠油、超稠油油藏,在开采过程中涉及掺稀、注气、注水等多种作业,且每完成一种作业,就需要单独起下一趟作业管柱。注水注气单流阀主要由上、下接头总成、紧定螺钉、压缩弹簧、密封筒、剪切销钉、滑动芯轴和密封组件组成,其设计思路包括液体循环流动设计,打开、关闭机构设计,以及密封组件设计等方面。室内试验及现场应用结果表明,该阀可以在起下一趟作业管柱时完成注气、替油等多种作业,满足了生产要求。 Ordovician oil reservoir in Tahe Oilfield is one with extra -heavy oil .A variety of operations is ap‐plied to recovery process ,including diluting operation ,gas injection and water injection ,each of which needs a single trip of operation string .The check valve for water and gas injection consists of upper and lower con‐nector assembly ,set screw ,pressure spring ,sealed chamber ,shear pin ,slide dabber and seal assembly .Its design thinking covers the design of liquid cycle flow ,of on-off mechanism and of seal assembly .Its indoor test and site application show that it can help complete a variety of operation with a single trip ,meeting pro‐duction requirement .
