摘要
针对近几年渤海油田新建小平台电潜泵修井检泵作业难的问题,根据这些小油田和边际油田的开发特点,研制了双电潜泵系统。该系统在油井中同时下入2套电潜泵,这2套电潜泵以并联方式安装在同一油井中不同的层位,共用1根油管采油,可按先后顺序启用2套机组总成。现场应用表明,该系统不但可实现较长时间的采油期,延长电潜泵的寿命,减少作业次数,而且有利环保,减少污染,有十分明显的经济效益。
Electric submersible pump is an important type of equipment in offshore oilfield.In recent years,there have been newly installed a few platforms including unattended wellhead platform.Among these platforms,some don't have workover equipment and some share one.Therefore,it requires a longer time to pump oil but having no workover operation on these platforms.Aimed at this problem and according to the development characteristics of small oilfields and marginal oilfields in the Bohai Bay,a dual electric submersible pump system is developed.And these two sets of ESP are installed by the parallel way in the different layers of the same well.Only one oil well tubing is used for oil extraction and both units are initiated in order of precedence.The effect of locale application indicates that a longer-stage of oil production can be realized in this system,the running life of ESP can be extended,and the operation times can be reduced.Moreover,it is helpful to environmental protection,reduces the pollution,and creates notable economic benefits.
