Abstract
(EN)
A four electrodes combination and arrangement method for sea electromagnetic exploration comprises the step of recording six horizontal electric field components ((M11N11, M12N21, M13M21, N13N22, M23N23, M22N12)) by combining the four electrodes, wherein each electrode has three separate grounded pins, and respectively connects to the other three electrodes through a wire. The loss of electromagnetic data is prevented according to the method above.
(FR)
L’invention concerne une combinaison de quatre électrodes et un procédé d’agencement pour exploration électromagnétique en mer, lequel procédé comprend les étapes consistant à enregistrer six composantes de champ électrique horizontal ((M11N11, M12N21, M13M21, N13N22, M23N23, M22N12)) en combinant les quatre électrodes, chaque électrode possédant trois broches de terre séparées et se raccordant respectivement aux trois autres électrodes par un fil métallique. Selon le procédé précité, la perte de données électromagnétiques est ainsi évitée.
