Title (EN) ADAPTIVE CONTROL CONCEPT FOR HYBRID PDC/ROLLER CONE BITS
(FR) CONCEPT DE COMMANDE ADAPTATIF POUR TRÉPANS À CÔNE DE ROULEMENT/PDC HYBRIDE
Abstract:
(EN) An earth boring drill bit comprising a bit body having a longitudinal axis along a path of the bit, a first plurality of cutters mounted to the body, and a second plurality of cutters rotatably mounted to the body, wherein a longitudinal axial relationship between the first plurality of cutters and the second plurality of cutters is adjustable. The first and/or second plurality of cutters may be mounted to the body in such a manner as to allow them to slide parallel to the longitudinal axis. The longitudinal axial relationship may be adjusted to exchange the first plurality of cutters and the secondary plurality of cutters between a primary cutting position and a secondary cutting position. The bit may include a sensor to provide an indication of a formation type being excavated by the bit and a processor to control the longitudinal axial relationship based on the indication.
(FR) L'invention porte sur un trépan de forage terrestre, qui comprend un corps de trépan ayant un axe longitudinal le long d'un trajet du trépan, une première pluralité d'éléments de coupe montée sur le corps et une seconde pluralité d'éléments de coupe montée de façon à pouvoir tourner sur le corps, une relation axiale longitudinale entre la première pluralité d'éléments de coupe et la seconde pluralité d'éléments de coupe étant réglable. La première et/ou seconde pluralité d'éléments de coupe peut être montée sur le corps de façon à permettre à ceux-ci de coulisser parallèlement à l'axe longitudinal. La relation axiale longitudinale peut être réglée de façon à échanger la première pluralité d'éléments de coupe et la seconde pluralité d'éléments de coupe entre une position de coupe primaire et une position de coupe secondaire. Le trépan peut comprendre un capteur pour délivrer une indication d'un type de formation qui est excavé par le trépan et un processeur pour commander la relation axiale longitudinale en fonction de l'indication.
