Abstract: 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%.
