Abstract

L'invention concerne un connecteur électrique à accouplement inductif destiné à permettre l'échange de signaux électriques entre l'extérieur et l'intérieur d'un puits dont la tête de puits (20) est coiffée d'un bloc de vannes (10). Le connecteur comprend au moins deux bobines électriques (1A, 1B; 5A, 5B) dont les axes respectifs d'enroule­ ment sont alignés avec l'axe (zz′) de la tête de puits. Lesdites bobines sont intégrées à un raccordement hydraulique formé entre le bloc de vannes et un dispositif de suspension (22) d'une colonne de production (40) logé dans la tête de puits, l'une des bobines étant solidaire du bloc de vannes (10) tandis que l'autre desdites bobines est solidaire du dispositif de suspension (22) de la colonne de production. The invention relates to an electrical connector with coupling inductive intended to allow the exchange of electrical signals between the exterior and interior of a well, the well head (20) of which is topped with a block of valves (10). The connector includes at least two electric coils (1A, 1B; 5A, 5B) with their respective winding axes ment are aligned with the axis (zz ′) of the wellhead. Said coils are integrated into a hydraulic connection formed between the valve block and a suspension device (22) of a production column (40) housed in the wellhead, one of the coils being integral with the valve block (10) while the other of said coils is integral with the device for suspension (22) of the production column.
