Application of modified integral resonant control for suppressing stick–slip oscillations in drill-strings / Zakaria Taibi

Public ISBD Titre : Application of modified integral resonant control for suppressing stick–slip oscillations in drill-strings Type de document : document multimédia Auteurs : Zakaria Taibi, Auteur ; Abdenour Djokhdem, Auteur ; Mohamed Riad Yousfi, Directeur de thèse Editeur : Laghouat : Université Amar Telidji - Département de génie des procédés Année de publication : 2024 Importance : 60 p. Accompagnement : 1 disque optique numérique (CD-ROM) Note générale : Option : Gas engineering Langues : Français Résumé : This thesis addresses the issue of unwanted downhole vibrations that hinder the efficiency of drilling operations, increasing costs and associated risks. The focus is on the "stick-slip" vibrations phenomenon, one of the significant challenges in deep drilling operations. Simulation results demonstrated that applying an MIRC controller can effectively reduce these vibrations and improve the stability of drilling operations. The simulation model illustrates how this controller can be integrated with the drilling system to achieve quick and precise responses to changes in torque, enhancing drilling efficiency and reducing bit wear and equipment failure. note de thèses : Mémoire de master en génie des procédés Application of modified integral resonant control for suppressing stick–slip oscillations in drill-strings [document multimédia] / Zakaria Taibi, Auteur ; Abdenour Djokhdem, Auteur ; Mohamed Riad Yousfi, Directeur de thèse . - Laghouat : Université Amar Telidji - Département de génie des procédés, 2024 . - 60 p. + 1 disque optique numérique (CD-ROM).
