注水泵运行参数优化及最小单耗的实现

为了定量分析泵的能耗，利用单耗和注水泵运行参数，建立了注水泵运行参数优化的数学模型。以减小单耗为注水泵节能运行的目标，给出了注水泵优化的约束条件，根据目标函数和约束条件，推导出注水泵单耗的计算公式。实际算例表明，注水泵可以实现最小单耗，泵的最合理运行工况是：在满足工艺压力或排量的前提下，泵压尽可能最低而泵效又在高效区。要实现机泵运行管理的最大节能，合理的压差应保持在0．3MPa内；在注水工艺设计时，应最大限度地降低注水压力，选用水力性能与工艺完全耦合的高效泵，运行于最佳工况区。

Optimization of operating parameters of waterflooding pump

By using energy consumption at unit pumping rate (ω) and operating parameters of waterflooding pump,a mathematical model for optimizing the operating parameters is established. By taking ω as object, the constraint conditios forthe optimization are put forward The equation for calculating ω is given based on the objective function and constraintconditions. To achieve the minimum energy consumption, the waterflooding pressure should be reduced as low as possible, and the rational pressure difference should be kept not more than 0.3MPa.
