高黏度介质注水泵设计与应用

Design and Application of High Viscosity Medium Injection Pumps

根据油田注水工艺将高黏度的井场作业废水回注的要求,以及常规注水泵在油田实际应用中出现的阀组件寿命短,维修频繁,无法完成正常注水的要求等问题,设计了高黏度介质注水泵。对注水泵液力端的阀腔流速、阀隙流速等关键数据的控制,改进了液力端结构,避免气蚀现象,最终满足注水工艺条件,注水泵各项性指标能达到了预期效果。

According to the requirement of waste water reinjection process in oil field and the problems of use of conventional injection pump,such as short working life and frequent maintenance,causing not implement of normal injection requirement,a new injection pump was designed.Aiming at the control of flow rate of valve cavity and valve gap,and the structure of hydraulic end was improved to avoid air corrosion to meet injection process.The injection pump meets the expected efficiency.
