井下油水分离器在Alliance油田的应用

油田开发后期的油井高含水，会造成油井减产、采油费用上升和环境污染。为此，加拿大工程研究中心研制成功了一系列可用于有杆泵、螺杆泵、电潜泵的井下油水分离器，并已将电泵井井下油水分离系统在Alliance油田投入矿场应用。使用结果表明，采用它可使油井增产原油、降低采水和水处理费用，并可保护生态环境。

The application of downhole separation system in Alliance oil field

At the upper development of oil field 0 the high water cut may reduce oil production rate, increase oil recovery expenses and pollute circumstance. So, the Canada Engineering Research Center develop a series of downhole separators which can applied to beam pump 0 progressive cavity pump, electric submersible pump, and have applied electric submersible pump downhole separation system to Alliance oil field. The result indicated that the new technic can increase oil production rate, reduce water oroduction rate and expenses of water technology and protect environment.
