介绍了一种新型高效长寿命提捞抽子的结构及工作原理。该抽子改善了现有提捞抽油机提捞抽子存在的胶筒耐磨性能差、抽子密封性差、在捞油作业中原油的漏失率大等问题。现场试验应用表明,该抽子可在油田得到广泛应用及推广。
This paper introduces the structure and working principle of a new type of high efficiency and long life lifeline pumping. The pump improves the problems of poor abrasion resistance, poor pump tightness and the loss rate of crude oil in the fishing operation of the existing pumping fishing pumping unit. Field test application shows that the pumping can be widely used in the oil field and promotion.
