BIT SAVER ASSEMBLY AND METHOD
A bit saver assembly having an inner valve sleeve that actuates upon the weight-on-bit (WOB) of the drill bit exceeding a threshold value to overcome the countervailing force provided by a spring contained within the bit saver assembly and the internal flow pressure of the drilling fluid at the area...

| description | A bit saver assembly having an inner valve sleeve that actuates upon the weight-on-bit (WOB) of the drill bit exceeding a threshold value to overcome the countervailing force provided by a spring contained within the bit saver assembly and the internal flow pressure of the drilling fluid at the area of the inner valve sleeve. Actuation of the inner valve sleeve opens a fluid passage to the wellbore annulus resulting in a reduction of drilling fluid flow pressure and the stretch of the drill string thereby reducing WOB of the drill bit without operator assistance.
La présente invention concerne un ensemble d'usure de trépan comprenant un manchon de soupape interne qui agit sur le poids au trépan (WOB) du trépan qui dépasse une valeur de seuil pour compenser la force de contre-pression fournie par un ressort contenu à l'intérieur de l'ensemble d'usure de trépan et la pression d'écoulement interne du fluide de forage au niveau de la zone du manchon de soupape interne. L'actionnement du manchon de soupape interne ouvre un passage de fluide vers l'espace annulaire de puits de forage, conduisant ainsi à une réduction de la pression d'écoulement de fluide de forage et l'étirement du train de tiges de forage, ce qui permet de réduire le WOB du trépan sans assistance d'un opérateur. |
