Abstract

DISPOSITIVO PARA LA INVESTIGACION POR MICROINDUCTIVIDAD DE UNA CARACTERISTICA DE FORMACIONES TERRESTRES ATRAVESADAS POR UN POZO DE SONDEO. INCLUYE UN CONJUNTO DE ANTENAS MONTADO SOBRE UN CUERPO ALARGADO LONGITUDINALMENTE, ADAPTADO PARA FIJARSE, DE FORMA DESLIZANTE, A LA PARED DEL POZO DE SONDEO. LA ANTENA ESTA COMPUESTA POR TRES ELEMENTOS QUE POSEEN ORIENTACIONES Y UBICACIONES QUE LOS SITUAN EN POSICIONES ELECTROMAGNETICAMENTE SIMETRICAS CON RESPECTO AL PRIMER ELEMENTO. SE INCLUYEN MEDIOS PARA ACOPLAR DIFERENCIALMENTE EL SEGUNDO Y EL TERCER ELEMENTO. LOS DISTINTOS ELEMENTOS PUEDEN ACTIVARSE PARA FUNCIONAR COMO TRANSMISOR, MIENTRAS QUE EL OTRO FUNCIONA COMO RECEPTOR.
