摘要
针对小排量高扬程螺杆泵在大庆油田中深井的试验情况,分析了螺杆泵使用范围,并进行经济效益评价。结果表明,中深井小排量螺杆泵适用于产液量在(1～13)t/d、泵挂深度1600m以下的油井举升,合理转速为(60～140)r/min。定向井应用螺杆泵举升,井眼曲率不应大于5°/25m,并且应缩短洗井周期。螺杆泵与抽油机相比,单井节省投资10万元。
In view of the experiment of small displacement high-lift screw pump in Daqing oilfeild medium-deep well,the screw pump＇s application range was analysed and the benefit evaluation was done.The results show that medium-deep well small displacement screw pump applys to the oil well lifting in which the fluid production is at （1~13） t/d,the depth of plunger under 1 600 m and advisability rotary speed is （60~140） r/min.When the screw pump lifting applied in the direction well,the borehole curvature should be not more than 5°/25 m and the purge period should be shortened.In comparison to the beam pumping unit,the screw pump single well investment cut down 100 000 yuan.
