Title (EN) METHOD OF DESIGNING A BOTTOM HOLE ASSEMBLY AND A BOTTOM HOLE ASSEMBLY
(FR) PROCÉDÉ DE CONCEPTION D'UN ENSEMBLE DE FOND, ET ENSEMBLE DE FOND
Abstract:
(EN) A bottom hole assembly containing a drill bit. The drill bit additionally has a plurality of primary cutter elements mounted thereto. The plurality of cutter elements comprise one or more first cutter elements and one or more second cutter elements. The second cutter element differs from the first cutter element in at least one cutter element property. The first cutter element has a diamond body containing a first region comprising an infiltrant material disposed within the interstitial regions. The first region is located remote from the working surface of the diamond body. The first cutter element also contains a second region comprising interstitial regions that are substantially free of the infiltrant material. The second region is located along at least the working surface of the diamond body. Also included are a cutter element, method of designing a bottom hole assembly as well as method of designing a drill bit.
(FR) L'invention concerne un ensemble de fond comprenant un trépan. Une pluralité d'éléments de molettes primaires est en outre montée sur le trépan. La pluralité d'éléments de molettes comporte un ou plusieurs premiers éléments de molettes et un ou plusieurs deuxièmes éléments de molettes. Le deuxième élément de molette diffère du premier élément de molette par au moins une propriété d'élément de molette. Le premier élément de molette est doté d'un corps de diamant contenant une première région comportant un matériau infiltrant disposé dans les régions interstitielles. La première région est située à l'écart de la surface de travail du corps de diamant. Le premier élément de molette contient également une deuxième région comportant des régions interstitielles sensiblement dépourvues du matériau infiltrant. La deuxième région est située au moins le long de la surface de travail du corps de diamant. L'invention concerne également un élément de molette, un procédé de conception d'un ensemble de fond ainsi qu'un procédé de conception d'un trépan.
