Title (EN) SPLIT-COIL, REDUNDANT ANNULAR COUPLER FOR WIRED DOWNHOLE TELEMETRY
(FR) COUPLEUR ANNULAIRE REDONDANT À PRISES POUR TÉLÉMÉTRIE PAR CÂBLE EN BAS DU TROU
Abstract:
(EN) An annular coupler for transmitting data across a tool joint may include a first coupler segment spanning a first portion of the circumference of the annular coupler. The annular coupler may further include a second coupler segment, electrically insulated from the first coupler segment, which spans a second portion of the circumference of the annular coupler. In selected aspects, the first and second portions do not overlap one another along the circumference. In certain aspects, the first and second coupler segments each span about fifty percent of the circumference of the annular coupler. Thus, each coupler segment may make up roughly half of the annular coupler.
(FR) La présente concerne un coupleur annulaire apte à transmettre des données via un raccord de tiges. Le coupleur selon l'invention peut comprendre un premier segment de coupleur enjambant une première partie de la circonférence du coupleur annulaire. Le coupleur annulaire peut comprendre en outre un second segment de coupleur, isolé électriquement du premier segment de coupleur, qui enjambe une seconde partie de la circonférence du coupleur annulaire. Dans des aspects sélectionnés de l'invention, les première et seconde parties ne se chevauchent pas le long de la circonférence. Dans certains aspects, les premier et second segments de coupleur enjambent chacun environ 50 % de la circonférence du coupleur annulaire. De ce fait, chaque segment de coupleur peut constituer une moitié du coupleur annulaire environ.
