Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO Y A UNA DISPOSICION DE UN TRANSMISOR PARA LA EXPLORACION DE AGUJEROS DE SONDEO (4). EL TRANSMISOR INCLUYE UN BUCLE CONDUCTOR SITUADO EN TIERRA (1) QUE SE ALIMENTA CON UNA CORRIENTE CON FORMA DE ONDA QUE INCLUYE AL MENOS UNA BAJA FRECUENCIA (POR EJEMPLO, 200-3000 HZ). LA FRECUENCIA ESTA CONTROLADA POR UN CRISTAL Y NORMALIZADA CON SEÑALES DE TIEMPO PROCEDENTES DE SATELITES GPS. EL RECEPTOR INCLUYE BOBINAS QUE FUNCIONAN PARA DETECTAR LAS VARIACIONES DE CAMPO QUE TIENEN LAS MISMAS FRECUENCIAS QUE EL TRANSMISOR Y ESTAN ALOJADAS EN LA SONDA (6), LA CUAL ES DESCENDIDA CON AYUDA DE UN TUBO DE PERFORACION TIPICO (5) Y CARECE DE CONEXION PARA LA SEÑAL CON EL TRANSMISOR. POR EL CONTRARIO, LA SONDA INCLUYE UN RELOJ DE CUARZO PRECISO QUE ES CALIBRADO FRECUENTEMENTE Y QUE PERMITE DETERMINAR SINTETICAMENTE LA FASE DE LA SEÑAL RECIBIDA CON RESPECTO A LA FASE DE LA SEÑAL DEL TRANSMISOR, POR EJEMPLO, MEDIANTE UN PROCESADOR DE SEÑAL. DEBIDO A QUE SE UTILIZA UNA VARILLA DE PERFORACION TIPICA, EL AGUJERO DE SONDEO PUEDE TENER CUALQUIER DIRECCION ELEGIDA Y PUEDE INCLUSO BLOQUEARSE CON LODOS, LECHADAS, ETC., EVITANDO ASI EL RIESGO DE QUE LA SONDA SE QUEDE ATASCADA EN ROCA DEFICIENTE, COMO SUCEDE EN EL CASO DE SONDAS TRANSPORTADAS POR LA LINEA DE SONDEO.
