泵控泵技术在大庆油田的应用

油田注水是国内油田稳产和增产的重要技术手段,油田的注水电耗占原油生产总成本的较大比例,故注水泵站的节能是关键.通过对泵站改造方案的比较和泵串联特性分析,首次提出了用增压泵控制串接大功率注水泵的泵控泵（Pump-Control-Pump）技术.PCP技术在大庆采油三厂北Ⅱ-3注水站的应用,解决了注水泵泵效低、泵管压差大、单耗高等问题,节能效果明显,并取得了良好的经济效益.

The application of PCP technique in DaQing oil field

Oil field water injection is an important technical method of stable and increasing production in home. Electric power consumption for water injection takes a great proportion in the total cost of oil production, however the energy-saving of water-flood pump station is the key. By comparing reclamation scheme of pump station and analyzing series property of pump, it is the first time to propose pump-control-pump technique that booster pump controls water-flood pump. The application of PCP technique in DaQing oil production factory dealt with series of problems that is low-level efficiency, high consumption, moreover, achieved positive energy-saving and economic benefits.
