2010年世界新型抽油机技术发展预测

近年来，世界新型抽油机有了很大发展。这些新型抽油机的主要特点是：采用了许多现代技术和先进结构方案以及新材料、新工艺，抽油机的适应性、经济性、可靠性和先进性以及技术水平均达到了有史以来的最高水平，为高效、经济。安全和可靠地开采石油资源做出了卓越贡献。文章阐述了长冲程抽油机（增大冲程抽油机、长冲程无游梁抽油机）、各种平衡抽油机（异相平衡、气囊平衡、变平衡力矩、自动平衡）和各种油井抽油机（高效能丛式井、斜井、最深井和自动化智能化）的技术发展。根据世界石油开采的需要以及技术发展趋势，预测了上述新型抽油机在2010年的技术发展，展现了世界新型抽油机的技术发展远景和全貌，预测2010年新型抽油机数量将会增多，但是占世界拥有量的比例不会很大。

DEVELOPING TREND OF WORLD NEW TYPE WELL PUMPING UNIT IN 2010

In recent years, world new-type well pumping units have got great development. Main characteristics of these pumping units are: having adopted many modern technologies, advanced structure, new materials and new technology, the flexibility, economics, reliability, advantages and state-of-art of well pumping units have attained unprecedented topmost level. The new well pumping units can efficiently, economically, safely and reliably develop petroleum resources. The article introduces technical development of long stroke pumping unit (including incremental-stroke well pumping unit and long stroke blue elephants), all kinds of equilibrium well pumping unit (including out-of-phase balance, gas pocket balance, variable counterbalance moment and automatic balance) and all kinds of well pumping units for oil well (including for high efficiency cluster wells, deflecting well, ultradeep wells and automatization well). According to requirement of world petroleum production,technical developing trend of new type well pumping units in 2010 are predicted.
