摘要
为了探索低渗透油田适用的平衡判定方法,合理调整抽油机平衡,进一步降低机采举升能耗,开展了抽油机平衡与能耗关系研究。通过对比现场应用的不同平衡判定方法调整效果的准确性和能耗情况得出:在低渗透油田开展平衡调整,应用平均功率法要比峰值电流法判定抽油机平衡的准确性高,能够使抽油机达到最低能耗的运行状态,最大限度节约能源;平均功率法判定抽油机平衡的标准宽泛,应用平均功率法判定抽油机平衡的平衡度区间在70%~120%内时,抽油机能耗变化不大,抽油机运行处于最佳平衡状态,能够实现最佳能耗运行状态;抽油机由峰值电流平衡状态调整到最佳平衡状态时,一般可以实现单井日节电11.2 k Wh的效果。因此,平均功率平衡判定方法更适用于指导低渗透油田抽油机平衡调整,能够实现抽油机最低能耗运行,对油田节能降耗工作具有一定的指导意义。
In order to explore the balance determination method applicable to low-permeability oilfields, rationally adjust the balance of pumping units, further reduce the energy consumption of pumping and lifting, and develop the relationship between pumping unit balance and energy consumption. By comparing the accuracy and energy consumption of the different balance determination methods applied in the field, it is concluded that the balance adjustment is implemented in low-permeability oilfields, and the average power method is more accurate than the peak current method to determine the balance of the pumping unit, enabling pumping. The oil machine reaches the lowest energy consumption operation state to save energy to the maximum; the average power method determines the standard of the pumping unit balance is broad, and the average power method determines the balance of the pumping unit balance in the range of 70% to 120%. The oil machine energy consumption does not change much, pumping unit operation is in the best balance, and the best energy consumption operation state can be achieved. When the pumping unit is adjusted from the peak current balance state to the optimal balance state, the single well daily electricity can be generally realized. 11.2 Effect of KWh. Therefore, the average power balance determination method is more suitable for guiding the balance adjustment of pumping units in low-permeability oilfields, and can achieve the lowest energy consumption operation of pumping units, which has certain guiding significance for energy saving and consumption reduction in oil fields.
