FIELD: oil and gas industry.
SUBSTANCE: electrode system contains hollow metal housing filled with dielectric liquid and provided with the openings covered with annular flexible membrane. Electrode system also includes central positive electrode isolated from the housing and negative electrode connected to the housing and coaxially installed relative to positive electrode. At that, annular flexible membrane is installed inside hollow housing. Besides, flexible membrane tightly envelopes negative electrode on one side, and positive electrode insulator - on the other.
EFFECT: improving strength and reliability of electrode system of the device both at lowering to the well and at operation at perforation interval, as well as improving the well treatment quality.
