A threaded oilfield tubular connection includes a box connector 12 having internal threads 16, 18, and a pin connector 14 having external threads 22, 24 for mating with the internal threads. Each of a box torque shoulder 20 and a pin torque shoulder 26 may be negative angle shoulders, and the thread flanks on the internal and external threads may also be negative angle load flanks. The connector substantially maintains a desired preload when dope is trapped between the threads during makeup. Another embodiment provides positive angle torque shoulders and positive angle load flanks.

L'invention porte sur un raccord tubulaire d'huile fileté pour champ de pétrole, lequel raccord comprend un raccord femelle (12) ayant des filetages internes (16, 18), et un raccord mâle (14) ayant des filetages externes (22, 24) destinés à s'accoupler avec les filetages internes. Chacun d'un épaulement de couple femelle (20) et d'un épaulement de couple mâle (26) peut être un épaulement à angle négatif, et les flancs de filets sur les filetages internes et externes peuvent également être des flancs de filet à angle négatif. Le raccord maintient sensiblement une précharge souhaitée lorsqu'un dopant est piégé entre les filetages durant un blocage. Un autre mode de réalisation comprend des épaulements de couple à angle positif et des flancs de charge à angle positif.
