小区块油田近井采注水开发及配套机电系统设计

Near Well Production by Waterflooding in Small Block Oilfields and Design of Its Support Electromechanical System

针对小区块油田的注水开发,采用近井高扬程采注水技术,可简化注水规模和压缩投资。其配套机电系统的设计包括:水源井井下采水系统,地面电力系统和过滤系统,注水井井下注水系统。现场试验表明,应用这种近井高扬程采注水技术及其配套机电系统,可使小区块油田注水开采成本明显降低。

Based on the production by waterflooding in small block oilfields, a technique of production of near well with high discharge head is used to simplify the scale of waterflooding and reduce the investment. The design of its support e-lectromechanical system includes a downhole water producing system in water source well, a surface power system, filtration system and downhole water injection system of injection well. Field test indicates that the cost of production of waterflooding in small block oilfield is reduced obviously by using the technique and its support system.
