海底油气多相混输泵的研究与应用

摘要

随着石油工业的发展,国外各公司、科研机构等均投入大量的人力物力进行研究海底油气多相混输技术.而研究其核心设备的多相混输泵更是发展海底多相混输技术的重中之重.分析了研究海底多相混输泵的意义,简要综述国内外螺旋轴流泵、双螺杆泵等各种海底油气多相混输泵的研究与应用情况,并描述了不同泵的特点、工作原理和应用范围.%As the develop of oil industry, foreign companies and research institutes spend plenty of resources on the research of subsea multiphase transport technology.Studying the multiphase pump is most important because of it' s the core equipment of subsea multiphase transport system.The worth of doing research on subsea multiphase pumps was analyzed,and it was briefly described the research and application of subsea multiphase pumps such as helicon-axial pumps、twin-screw pumps and so on, as well as their features 、principles and working conditions.
