Definitions

  • the method is used to distribute the capacity of a non-ferrous layer in a foreign well in the borehole. Emission of two signals in the case of a positive effect increases the reception of antennas in the case of a single medium; a weak sum signal is used, which increases the amplification of the amplified When a signal appears near one of the transmitting antennas of a consumer area that are distinguished by a dielectric property, the signal received is subject to change.

The overall sensitivity of the method is also higher than the method based on the reception of an echo signal.

Abstract

Cette invention se rapporte aux procédés de prospection géophysiques, plus particulièrement à la radiolocalisation du sous-sol, et permet de découvrir et de définir les gisements d'irrégularités dans un massif de formations géologiques. Cette invention concerne essentiellement un procédé qui consiste à recevoir un signal d'énergie à l'aide de deux récepteurs, ceci en soustrayant d'un premier signal reçu un autre signal reçu et soumis à une conversion en échelle de temps ainsi qu'à un traitement préalable, et à déterminer la différence entre les signaux. Ce dispositif comprend une unité de localisation différentielle comprenant un émetteur, des récepteurs, un inverseur de phase ainsi qu'un additionneur. Les sorties des récepteurs sont reliées à l'entrée de l'additionneur, la sortie d'un récepteur étant reliée à l'entrée de l'additionneur par l'intermédiaire de l'inverseur de phase. Les antennes de réception sont disposées de manière symétrique par rapport à l'antenne d'émission. Cette invention permet d'obtenir une grande protection contre les interférences, une grande précision et une grande efficacité dans le domaine de la cartographie géologique, des recherche du génie civil, archéologique et autres.
