摘　　要：低频电脉冲采油技术是通过升压、整流、充电等电路将电能蓄积在电容器中,通过触发电路,使能量瞬时释放,在井内液体中产生震动波,作用于地层,改善地层的渗流状况,达到提高采收率的目的。Ⅰ型设备在双河油田应用11井次,成功率72%;Ⅱ型设备在古城油田应用10井次,成功率90%。主要是由于Ⅰ型设备关键部件在处理油井时要放在井下,受高温、高压的影响及井下空间的限制,设备稳定性差、寿命短、能量小、效果差;Ⅱ型设备解决了上述问题,从而提高了试验成功率。The principle of low frequency electric impulsed production technique is that electric energy,stored in ca-pacitors through boosting,rectifying and charging circuits,are released instantaneously by trigger circuits to produce vibration waves which can improve seepage flow in forma-tions,thus enhancing recovery factor.TypeⅠequipment has been used for11times in Shuanghe oilfield with a success rate of72%,while typeⅡfor10times in Gucheng oilfield with a success rate of90%.
