Title (EN) DRILL BIT DISTANCE TO HOLE BOTTOM MEASUREMENT
(FR) MESURE DE LA DISTANCE ENTRE UN TRÉPAN DE FORAGE ET UN FOND DE TROU
Abstract: front page image
(EN)Systems and methods for drilling a wellbore. The method includes measuring a first distance that a drilling device is raised while connected to a drill string, determining a weight-on-bit in the drill string, determining a second distance to lower the drilling device such that a drill bit at a lower extremity of the drill string approaches toward a bottom of the wellbore, based on the first distance and the weight-on-bit, and lowering the drilling device by the second distance.
(FR)L'invention concerne des systèmes et des procédés permettant de forer un puits de forage. Le procédé consiste à mesurer une première distance sur laquelle est élevé un dispositif de forage pendant qu'il est raccordé à un train de tiges de forage, à déterminer une charge sur le trépan dans le train de tiges de forage, à déterminer une seconde distance pour abaisser le dispositif de forage de telle sorte qu'un trépan à une extrémité inférieure du train de tiges de forage s'approche d'un fond du puits de forage, en se basant sur la première distance et sur la charge sur le trépan, puis à abaisser le dispositif de forage selon la seconde distance.
