FIELD: oil and gas production.
SUBSTANCE: well is equipped with casing string communicated with geological formation. The essence of the invention is like follows: first converter (14) is set in the first location. The first converter consists of two electrodes corresponding to first (141) and second (142) lower electrodes. The first and the second lower electrodes are in electrical contact with the casing string. Second converter (15) is set in the said second location. The second converter consists of two electrodes corresponding to first (151) and second (152) higher electrodes. The first or the second converters emit an electric signal applying it between corresponding electrodes. The second or the first converter receive the electric signal recording it with corresponding electrodes.
EFFECT: independence from geometric characteristics of well and fluid impedance, production string, casing string and formation.
