Abstract

Une réduction à isolement par l'air électrique compacte, robuste, résistante à l'usure et haute performance pour utilisation avec la télémétrie EM de forage est divulguée. Dans un mode de réalisation, la réduction à isolement par l'air peut inclure un mandrin fileté extérieurement séparé d'un logement fileté intérieurement par un matériau diélectrique. En outre, certaines configurations peuvent comprendre une bague d'écartement externe pour séparer les moitiés électriques supérieure et inférieure de la réduction qui offre un soutien structurel, agit en tant que joint primaire externe et fournit une longueur résistante à l'abrasion non conductrice à l'extérieur. Certaines configurations peuvent inclure des tiges de torsion pour empêcher le dévissage possible des sections filetées diélectriques remplies si le matériau diélectrique devait être endommagé ou affaibli.
