POLE CONFIGURATION METHOD WITH FOUR-POLE INTERCOMBINATION INTENDED FOR MARINE ELECTROMAGNETIC SURVEY

摘要

FIELD: electricity.;SUBSTANCE: invention is related to marine electromagnetic survey. Essence: six horizontal components of an electric field are used for this method. These electric field components are provided by three-pin ground electrodes of four poles connected in pairs. One of the pins of three-pin ground electrodes and pins of the other three three-pin ground electrodes form in pairs six horizontal components of electric field. Simultaneously data are recorded on change of electromagnetic field in time.;EFFECT: provision of effective recording of electric field at angle of less than 22,5 degrees in direction of activation notwithstanding orientation of the detecting station, guarantee of effective communications between source of activation field and paired pole intended to record electric field, relaxation in requirements to orientation of the detecting station and direction of movement and position for the source of activation field during data acquisition, excluding losses of electromagnetic data.;9 cl, 2 dwg
