The present invention discloses the use of calcium sulfonate based greases compounds for use in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces such as those present in threaded connections, and, especially in threaded connections associated with oilfield applications. The present invention also discloses methods for making and using such greases and compounds in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces.
La présente invention concerne l'utilisation de graisses à base de sulfonate de calcium utilisées dans des applications dans le cadre desquelles les composés sont exposés de manière continue, périodique ou intermittente aux fluides qui contaminent, érodent, ablatent ou enlèvent ou perturbent de toute autre manière la capacité des composants de protéger des surfaces de contact telles que celles dans les raccords filetés et notamment dans les raccords filetés associés aux applications de forage de pétrole. La présente invention concerne aussi des procédés de fabrication et d'utilisation de ces composés dans une application dans laquelle les composés sont exposés de façon continue, périodique ou intermittente aux fluides qui contaminent, érodent, ablatent ou enlèvent ou perturbent de toute autre manière la capacité des composants de protéger des surfaces de contact.
