液压抽油机研究现状及展望
Research Situation and Development Prospect of Hydraulic Pumping Unit
摘要
Abstract
Compared to the traditional beam pumping unit,hydraulic pumping units have the following advantages:more compact in structure,lighter in weight,lower in cost,smooth and steady in running,easier in realizing long stroke and adjusting frequency stroke and safety protection,very efficient in energy saving,and so on.Therefore hydraulic pumping units have attracted considerable attention of industry people and have been applied more and more widely in industry.Hydraulic pumping units are developed relatively early abroad,and currently they have been used in oil field successfully.Although hydraulic pumping units are studied a little late in China,some of the prototypes are also applied on testing ground.In this study,the research situation and application of hydraulic pumping units at home and abroad are summarized,and the development prospect of hydraulic pumping units is presented,which is served as a reference for industry people.关键词
