Title (EN) DRILLING ENERGY CALCULATION BASED ON TRANSIENT DYNAMICS SIMULATION AND ITS APPLICATION TO DRILLING OPTIMIZATION
(FR) CALCUL D'ÉNERGIE DE FORAGE BASÉ SUR UNE SIMULATION DE DYNAMIQUE TRANSITOIRE ET SON APPLICATION À L'OPTIMISATION DU FORAGE
Abstract: front page image
(EN)A method for drilling a well includes applying energy input to a drill string (31) by at least one of rotating the drill string (31) from surface and operating a drilling motor (41) disposed in the drill string (31) to operate a drill bit (2) at a bottom of the drill string (31); an amount of the applied energy not consumed in drilling formations caused by at least one of motion, deformation, and interaction of the drill string (31) is calculated; an amount of the applied energy used to drill formations below the drill bit (2) is calculated; and at least one drilling operating parameter is adjusted based on energy calculation before or during drilling operation.
(FR)L'invention concerne un procédé de forage d'un puits, comprenant l'application d'un apport énergétique à un train de tiges de forage (31) par au moins une opération parmi la rotation du train de tiges de forage (31) à partir de la surface et le fonctionnement d'un moteur de forage (41) disposé dans le train de tiges de forage (31) pour mettre en œuvre un trépan (2) au niveau du fond du train de tiges de forage (31); une quantité de l'énergie appliquée non consommée dans les formations de forage à cause d'au moins l'un parmi un mouvement, une déformation et une interaction du train de tiges de forage (31) est calculée; une quantité de l'énergie appliquée utilisée pour forer les formations en dessous du trépan (2) est calculée; et au moins un paramètre opérationnel de forage est ajusté sur la base du calcul d'énergie avant ou pendant l'opération de forage.
