    Abstract：Due to ultra low permeability and strong heterogeneity in Changqing Oilfield reservoir， water can not be injected into many wells or enough water can not be injected in water injection development， which will result in serious effect on stable oil production for a long time. If adopted is the conventional measure for injecting more water into wells， its period of validity will be short. Therefore， adopted is the electronic pulse stimulation injection technique in ultra low permeability reservoir. In this technique， underground electronic pulse device generates low frequency pulse wave continuously， the pulse wave acts on oil layer and generates high voltage discharge in reservoir liquid to treat stratum. The characteristic of this technique is usage of electronic pulse device to generate powerful shock wave and relieve pollution in near well-bore area in order to de-plug and increase water injection. Field application in ten wells shows that water injection effect is good.
