%X 以基于二级的双头短幅外摆线型螺杆泵为研究对象，对腔室内压力形成以及举升压力和排量等举升性能进行分析。结果表明：与双头短幅内摆线型螺杆泵相比，双头短幅外摆线型螺杆泵的举升压力和排量均降低30%左右；油田用双头短幅内摆线型螺杆泵可以有效提高工作效率，节省时间，而双头短幅外摆线型螺杆泵生产和检修成本低，适用于产量低的浅井。;Taking two-stage double-thread short-amplitude internal cycloidied screw pump as the research object，the chamber pressure formation  and lifting performance such as lifting pressure and displacement were analyzed.The results show that，compared with the double-thread short-amplitude internal cycloidal screw pump，the lifting pressure and displacement of double-thread short-amplitude external cycloidal pump were reduced by about 30%.Therefore double-thread short-amplitude internal cycloidal screw pump used in oil field could improve work efficiency and save time more effectively，the production and maintenance costs of the double-thread short-amplitude external cycloidal screw pump were much lower，so it was suitable for shallow wells with low production
