摘要：针对胜利油田和大庆油田大排量柱塞系替代高压多级高心泵时出现振动大、噪声大等问题，胜利油田采取了如下措施：整机重心降低0.5m，在系进、出管道设计中等流速控制在1.2~1.8m/s经济流遵范图内：单体票头改为整体液力端，减少振源，方便操作。大庆油田在胜利油田试验基础上经过调研，选择对置式十柱塞注水泵和单边式五柱塞注水泵替代同参数高心注水泵，为减少振动和噪音，去掉了对置式泵机组的联合底座，直接安装在基础上：对单边式系机组的联合底座进行二次灌浆充实，达到减振、降噪目的。实施上速措施后机组运行趋于平稳，振动、噪音明显减小，为扩大矿场试验提供了技术保障。

Abstract: For shengli oilfield and daqing oil field large displacement piston pump replace ment when high pressure multistage centrifugal pump vibration and noise sound great, mea sures and methods were given.
Shengli oilfield to take the following measures: the whole
center of gravity lower 0.5 m, flow velocity in the pipe at the inlet and outlet of the pump design control in 1.2~1.8 m/s economic flow rate range; Monomer pump head instead of the whole hydraulic side, reduce the vibration source, convenient operation. Daqing oilfield in shengli oilfield through research and experiment on choose contraposition typeten plunger pump and unilateral typefive injection pump replaced with the parameters of the centrifugal
injection pumps,
in order to reduce vibration and noise, and remove the pump unit with
the joint of the base, directly instelled on the base; Joint base of unilateral pump unit second
Implementation
ary grouting enrichment,
reach the purpose of reducing vibration and noise.
of these measures in reduction of vibration and noise during unit running after leveled off pro vides technical which support to expand the field test.

提高注水泵效是油田增产、降低成本的重要举措。注水泵是油田的耗电大户，常用的DF250-150 型离心泵组1年仅电费支出就超过500万元，是设备价格的5倍以上。离心泵属于常年连续运转设备，其效率对电力消耗和注水成本影响很大。由于离心泵难以克服紊流等无效功耗，泵的最高效率为 78%，已接近极限，进一步提高效率的难度非常大。往复式柱塞泵为容积泵，具有出口压力高和效率高的特点，但同时因其传动原理所限，流量越大
