涉外油田小流量高扬程注水泵优化选型

Selection of Small Flow & High Pressure Injection Water Pump of Foreign Field

由于涉外油田具有注水量小、注水压力高、含大量氯离子、矿化度高的特点,本文从离心泵、柱塞泵的工作原理出发,对小流量高扬程的注水泵进行了比较,推荐在地处偏僻、经济落后的涉外项目中优先使用离心泵。

Foreign oil fields have water injection, high injection pressure, containing large amounts of chloride ions, the characteristics of high salinity, from the centrifugal pump, piston pump works starting small flow high head injection pumps, it is recommended priority in the use of centrifugal pumps located in remote, economically backward foreign project.
