‘Qing You’ long stroke pumping unit is a high velocity pumping unit. It is designed to achieve a large pump output of more than 200 m3/d with the diameter of rod pump less than 70mm, and the aunulus test can be conducted in the course of production.

Based on the analyzing of some pumping unit commonly used in oil field and the relationships between acceleration and various parameters, in this paper, the design considerations was presented. The maximum velocity υm of the new developed pumping unit is about 40% higher than the recommendation for υm of common pumping unit, and its maximum acceleration αm is in the range of that of the conventional ones.
