一、概况63年以来,大庆油田一直使用高压离心泵注水。至目前为止、主要泵型有 D 155—170,150D—170,6D—100,DG270—150等,共计208台。总装机名牌注水能力为728808米~3/日,总装机容量为269510瓩。约占全油田总用电量的40%以上。多年来、这些泵基本上满足了高压,大排量,平稳的注水要求,对油田生产起着重要作用。但从节约能源的意义来看,这些泵普遍存在着效率低的问题。其平均效率为 I. Overview 63 years ago, Daqing Oilfield has been using high pressure centrifugal pump water. So far, the main pump type D 155-170,150 D-170,6 D-100, DG270-150, a total of 208 units. The total installed capacity of brand-name waterfill 728808 m ~ 3 / day, the total installed capacity of 269510 瓩. Accounting for more than 40% of the total electricity consumption of the whole field. Over the years, these pumps have basically met the high pressure, large displacement, smooth water injection requirements, plays an important role in oilfield production. However, in terms of saving energy, these pumps generally have the problem of low efficiency. Its average efficiency is
