METHOD AND DEVICE FOR CARRYING OUT MARINE ELECTRICAL EXPLORATION DURING A SHIP TRAVEL

The inventive method for reducing a noise effect during a ship travel consists in generating direct current pulses, the parameters of which are set up according to a section conductivity and the depth of a formation, in simultaneously measuring the electric field on pairs of receiving electrodes on the basis of the space average of a double electric layer potential originated at the electrode-water interface during the pulses and intervals therebetween and in determining geoelectrical parameters. The inventive device comprises a unit for forming an exciting field, in which a switchboard generates pulses on feeding electrodes and a generator consists of two mutually parallel cable lines with emitting electrodes, a nonradiative dummy device in the form of a pair of opposite electric dipoles having equal moments and a measuring unit with pairs of sectional receiving electrodes, wherein the total length of the electrode section is equal to or less than 5% the interelectode distance and the communication between the electrode elements connected to a receiving line via a common input/output makes it possible to add electromotive forces generated therein.
