Title
(EN) SYSTEM AND METHOD FOR WELL DRILLING CONTROL BASED ON BOREHOLE CLEANING
(FR) SYSTÈME ET PROCÉDÉ DE COMMANDE DE FORAGE DE PUITS BASÉE SUR UN NETTOYAGE DE TROU DE FORAGE
Abstract
(EN)
Systems and methods for determining the cleaning effectiveness of a well borehole during drilling. A control system may monitor various parameters, including the volume of drilling mud and any materials entering a borehole, including by a flow rate, and the volume of fluids and materials (such as drilling mud and rock) exiting a borehole, including by a flow rate, and determining if there is a difference, the value of any such difference, whether the value is within one or more target ranges, falls below a threshold therefor, or exceeds a threshold therefor. If the control system determines that the value of the difference in volumes indicates that corrective action is appropriate, then taking such corrective action by modifying one or more drilling parameters.
(FR)
L'invention concerne des systèmes et des procédés de détermination de l'efficacité de nettoyage d'un trou de forage de puits pendant un forage. Un système de commande peut surveiller divers paramètres, y compris le volume de boue de forage et tous les matériaux entrant dans un trou de forage, y compris par un débit, et le volume de fluides et de matériaux (tels que la boue de forage et la roche) à sortir d'un trou de forage, y compris par un débit, et à déterminer s'il existe une différence, la valeur d'une telle différence, si la valeur s'inscrit dans une ou plusieurs plages cibles, tombe au-dessous d'un seuil y associée, ou dépasse un seuil y associée. Si le système de commande détermine que la valeur de la différence de volumes indique que l'action corrective est appropriée, alors il est pris une telle action corrective par modification d'un ou plusieurs paramètres de forage.
