在不影响油井产量的前提下,为实现降低工人劳动强度、提高抽油机效率、降低开采成本和提高经济效益的目的,开展了抽油机井节能"五项技术"的现场推广工作。通过应用变频控制器、伺服控制器、节能电动机提高电动机运行效率,应用空化射流器、电磁防蜡器工艺降低抽油机井举升负荷和延长热洗周期,实现了提高单井经济效益的目的。现场应用表明抽油机井节能"五项技术"具有很好的适应性,油井节电率超过13%,举升负荷得到有效降低,热洗周期超过1个月,满足了油田节能的实际需求。

Without decreasing oil production, in order to reduce workers labor intensity, improve the efficiency of oil pump unit, reduce the developing cost and increase the economic benefits, 5energy-saving technologies for oil pumping unit have been applied. The running efficiency of motor can be increased by using variable frequency controller, servo controller and energy- saving motor. The lifting load of oil pumping unit can be reduced and the thermal well- flushing period can be prolonged by using cavitation ejector and electro magnetic paraffin-control process. The increasing economic benefits of single well can be realized. The field application shows that 5 energy- saving technologies for oil pumping unit have better adaptability, the rate of power- saving is more than 13%, the lift load can be reduce effectively, the thermal well- flushing period can be prolonged over one month. The 5 energy- saving technologies can meet the requirements on oilfield energy- saving, reduce the energy- consumption for oil pumping unit and prolong thermal well-flushing period.The energy-saving effects are significant.
