摘　　要：群控技术采取“一变多井”模式,即一台变压器带动多口机械采油井,同时配备整流装置、逆变装置实现从交流电到直流电,再从直流电到交流电的转换。选取一个平台的16口井开展了现场试验,对变压器容量、单井控制进行研究与论证,测试结果表明,直流电经过逆变器变成交流电的效率平均可达97.67%,变压器的效率由改造前的97.86%提升至98.71%,提高了0.85%。应用群控技术后,变压器数量由16台减少为2台,产液单耗由18.24 kWh/t下降到15.34 kWh/t,下降了2.9 kWh/t。通过试验与论证,群控技术适用于一个采油平台上多口机械采油井,且变压器与最远端井的距离在1000 m范围内。The group control technology is adopted the"one-variable-multiple-wells"mode.That is to say,a transformer drives multiple mechanical oil wells and it is equipped with rectifier devices and inverter devices to achieve conversion from AC to DC,and then from DC to AC.The 16 wells from a platform are selected to carry out field tests to study and demonstrate transformer capacity and singlewell control.The tests results show that the average efficiency of converting DC into AC through inverters reached 97.67%.The efficiency of transformers is increased from 97.86%before the transformation to 98.71%,which increases 0.85%.After applying the group control technology,the number of transformers is reduced from sixteen to two,and the unit consumption of liquid production is decreased from 18.24 kWh/t to 15.34 kWh/t,which decreases 2.9 kWh/t.Through tests and demonstrations,the group control technology is applicable to multiple mechanical oil recovery wells on one oil production platform and the distance between the transformer and the farthest end well is within 1000 m.
