Engineering Tools and Technologies of Freeing of the Stuck Metal Drilling String

Abstract: available mathematical models of processes of releasing of the stuck drilling tools is carried out. The physical and mathematical dynamical models of both drilling rig and engineering tools for effort to bring down problems and accidents are considered. An analysis of available methods and mathematical models for studying the operating dynamics of the metal drilling string during geological exploration work and well drilling is made.Key words: drilling, stuck, drilling liquor, impact, vibration, drilling tool,… Show more

“…The existing reference documents and the literary sources known to us (Liu & Weber, 2012;Kozhevnikov et al, 2015;Kotskulych et al, 2016;Vytvytskyi et al, 2017) provide a number of recommendations for the installation of bow-spring centralizers, depending on the configuration of the well axis. General problems of interaction of columns with the borehole were considered, in particular, in the papers (Aleksandrov, 1982;Vlasiy et al, 2017;Levchuk, 2018;Kryzhanivskyi et al, 2018). Various approaches to the engineering simulation of contact phenomena in rod structures using classical theories of rods are proposed in publications (Mossakowskii et al, 1978;Bedzir et al, 1995;Neto et al, 2014;Shats'kyi et al, 2016;Popadyuk et al, 2016;Jawed et al, 2018).…”

“…The phenomenon of contact interaction between the elements of a drill string and the wall of a well is a key factor that determines the energy intensity of drilling process at string rotation. For this area, it remains relevant to mathematically model the static and dynamics of rod systems regarding the tasks on eliminating the pinching of a drill string [20][21][22]. Refinement of models of interaction between the surface of a rod and the elastic or non-elastic environment is required for the safe operation of long objects.…”

“…Феномен контактної взаємодії елементів бурильної колони зі стінкою свердловини є ключовим чинником, який визначає енерговитратність процесу буріння у випадку її обертання. У цьому напрямку актуальними залишаються питання математичного моделювання статики та динаміки стрижневих систем за умов взаємодії бічної поверхні стрижня з пружним або непружним середовищем стосовно задач ліквідації прихоплень бурильної колони [11].…”
