应用系统方法,将注采与压力系统联系起来,建立了一种优化图解法。可在不同含水期,不同的约束条件(定产、定压、定耗电)下,优选出合理的油水井数比,以指导注采系统的调整,确保最佳压力系统的建立。文中介绍了与注采有关的产液量、注水量、耗电量、相对利润的计算方法和确定压力系统的方法。并以萨尔图油田南五区作为注采及压力系统优化的实例。对高含水期全面转抽后,减少老井递减,降低能耗,提高经济效益,提供了一套调整的方法。
Application of system methods, the injection and production and pressure systems linked to establish an optimization diagram. Under different water conditions and different constraints (fixed production, constant pressure, fixed electricity consumption), a reasonable ratio of oil and water wells can be optimized to guide the adjustment of injection and production systems to ensure the establishment of the optimal pressure system. In this paper, the method of calculating the amount of fluid, water injection, power consumption, relative profit and the method of determining the pressure system are introduced. An example of the optimization of injection and production and pressure systems was adopted in the Southern Wu 5 area of Salto Oilfield. After a full diversion of high water cut period, reducing the decline of old wells, reduce energy consumption, improve economic efficiency, provides a set of adjustment methods.
