In　recent　years,　the　application　of　electrical　explosion　shockwave　as　a　stimulation　technology　is　increasing　in　oil　fields,　but　lacks　relevant　theoretical　knowledge　to　support　it.　In　view　of　this　problem,　a　research　was　carried　out　on　experimental　study　of　electrical　explosion　shockwave　stimulation　on　the　tight　sand　reservoir　to　determine　the　effective　range　of　the　resulting　effects.　An　experimental　platform　for　testing　electrical　explosion　shockwave　is　established.　Porosity,　permeability　and　other　mechanical　parameters　of　tight　sand　stone　samples　are　tested　before　and　after　electrical　explosion　shockwave　treatment.　The　result　shows　clear　improvement　of　the　above　mentioned　parameters　and　the　effective　range.
