煤层气排采井大多采用常规游梁抽油机,随着开采时间逐渐增长,煤层含水量减少,抽油机负荷不断变化,导致抽油机平衡度变化较大。同时由于采用变频节能电机,应用电流法调平衡,无法达到平衡度标准要求。通过对抽油机平衡度研究,及时调整抽油机平衡,降低电耗,减少设备损耗。 Most CBM production wells use conventional beam pumping units. As the mining time increases, the water content of the coal seam decreases, and the load of the pumping units changes continuously, resulting in great changes in the balance of the pumping units. At the same time as a result of frequency conversion energy-saving motor, the application of current balance method, balance can not achieve the standard requirements. Through the study on the balance of pumping units, timely adjust the balance of pumping units, reduce power consumption, reduce equipment losses.
