Title
(EN) SMART LOAD PIN FOR DRAW-WORKS
(FR) BROCHE DE CHARGE INTELLIGENTE POUR TREUIL DE FORAGE
Abstract
(EN)
A smart load pin may be configured to measure a load on a hook of a draw-works system. The smart load pin may also include circuitry to convert the measured load to a digital value representative of the measured load, wherein the digital value represents the value of the measured load in engineering units and to transfer the digital value representative of the measured load to a control system located at a derrick. The data from the smart load pin may be used in adjusting, with a control system, operation of the draw-works system based, at least in part, on the received digital value representative of the measured load.

La présente invention concerne une broche de charge intelligente qui peut être configurée pour mesurer une charge sur un crochet d'un système de treuil de forage. La broche de charge intelligente peut comprendre en outre un circuit pour convertir la charge mesurée en valeur numérique représentative de la charge mesurée, la valeur numérique représentant la valeur de la charge mesurée en unités d'ingénierie et pour transférer la valeur numérique représentative de la charge mesurée à un système de commande situé au niveau d'une tour de forage. Les données de la broche de charge intelligente peuvent être utilisées dans l'ajustement, avec un système de commande, du fonctionnement du système de treuil de forage, sur la base, au moins en partie, de la valeur numérique reçue représentative de la charge mesurée.
