A system for drilling a well comprises a tubular member having a bottomhole assembly at a bottom end thereof disposed in a wellbore. A first sensor is disposed in the bottomhole assembly at a predetermined axial location for detecting bending in a first axis and generating a first bending signal in response thereto, where the first axis is substantially orthogonal to a longitudinal axis of the bottomhole assembly. A second sensor is disposed in the bottomhole assembly at the predetermined axial location for detecting bending in a second axis and generating a second bending signal in response thereto, where the second axis is substantially orthogonal to the longitudinal axis. A processor receives the first bending signal and the second bending signal and relates the first bending signal and the second bending signal to a borehole curvature according to programmed instructions.
L'invention concerne un système de forage de puits qui comprend un élément tubulaire à ensemble fond de puits équipant une extrémité inférieure, disposé en fonds de puits. Un premier capteur se trouve dans cet ensemble en un point axial préétabli pour détecter une courbure selon un premier axe et produire un premier signal de courbure correspondant. Le premier axe est sensiblement orthogonal à un axe longitudinal de l'ensemble. Un second capteur se trouve dans l'ensemble en un point axial préétabli pour détecter une courbure selon un second axe et produire un second signal de courbure correspondant. Le second axe est sensiblement orthogonal à l'axe longitudinal. Un processeur reçoit le premier signal et le second signal et il les met en relation avec une courbure de puits de forage selon des instructions programmées.
