摘要
为了合理配置螺杆泵井的生产参数,使井和泵匹配,基于螺杆泵温度场以及泵内流体压力分布规律,以定子工作条件和泵举升性能为依据,建立了地面驱动螺杆泵井方案校核方法,绘制了方案校核图版.将生产方案划分为"合理方案区"、"烧泵区"和"泵‘击穿’区",提出了高效点和系统效率曲线相结合的生产参数优选方法,并以真实油井为例进行了计算分析.结果表明:高转速和高下泵深度会增加定子温度和泵举升高度,当其超过螺杆泵的临界使用值时即会引发"烧泵"和泵"击穿"现象.在现场应用中应根据方案校核图版上的高效点和系统效率曲线优选最佳生产参数组合,避开烧泵区和泵"击穿"区,以延长螺杆泵井的检泵周期,提高经济效益.
In order to optimally configure the production parameters of screw pump well and match well with pump,based on screw pump′s temperature field and pressure distribution law of internal liquid,with stator working conditions and pump lifting characteristics,a program checking method for screw pump well with surface-driving was established and a program checking plate was drawn,which divi-ded the production plan into reasonable program zone,pump burning region and pump breakdown area.By calculating and analyzing those parameters of two real oil wells,a production parameter optimizing method combining efficient point and system efficiency curve was proposed.The results show that high rotation speed and pump setting depth can increase stator temperature,improve lifting height,which will cause pump burn out or breakdown when they reach critical values.In order to avoid pump burning region and pump breakdown area and extend pump inspection cycle,improve economic efficiency,the optimal production parameter must be attained in field applications.
