【摘要】 我国油田地面注水系统效率低、耗电多、注水单耗高。有效提高注水系统效率和降低注水单耗是油田节能增效的重要课题。针对注水工艺以及注水系统各个环节的实际特点 ,提出了系统的能流模型和各注水单元的计算数学模型 ;结合中原油田卫城注水区块的实际情况建立了各注水单元效率的判断标准 ;编制了注水系统效率分析计算软件 ,通过分析该软件在卫城注水区块的实际应用结果 ,提出了如何提高我国油田主水效率的几条建议更多还原

【Abstract】 The ground water injection systems are of the characters of low efficiency, high electricity expense in China oil fields. Improving water flood efficiency and lowering electricity expense are the key way to achieve better economic results. This paper aimed at the actual situation of water flood technology and each link of water flood system , promoted the system energy flow mode and mathematical mode, combined the practical features of ZHONG YUAN field WEI CHENG water flood system advanced the water flood efficiency judge standard ,developed the water flood efficiency analyze software. This paper also put forward some suggestions about how to improve the water flood efficiency.更多还原
