Electric submersible pump(ESP)technology is the most important oil extraction method for offshore oilfield development.Due to the huge cost of offshore operations,improving the operating life of electric submersible pump wells is an important means to reduce costs and increase efficiency.A special study was conducted to address the issue of conventional electric submersible pump wells frequent operating outside the reasonable displacement range of the pump,resulting in wear of thrust bearings,wear reducing pads,and mechanical seals,accelerating the efficiency reduction and failure of the unit.A new wide-range pump type was developed to enhance the adaptability of the pump to changes in oil well production capacity.The process of on-site application shows that the wide range electric submersible pump technology can effectively widen the efficient zone of the pump,allow the pump to operate in light load for a long time and operation within the reasonable displacement range.This has achieve the effect of improving the management level of the electric pump well and extending the lifespan of individual well,and reduce the production cost of oilfield development.
