This ebook stories the result of exhaustive study paintings on modeling and regulate of vertical oil good drilling structures. it really is occupied with the research of the system-dynamic reaction and the removing of the main harmful drill string vibration modes affecting total perforation functionality: stick-slip (torsional vibration) and bit-bounce (axial vibration). The textual content is equipped in 3 parts.

The first half, Modeling, provides lumped- and distributed-parameter types that permit the dynamic habit of the drill string to be characterised; a entire mathematical version considering mechanical and electrical elements of the final drilling approach can also be supplied. The dispensed nature of the process is accommodated through contemplating a approach of wave equations topic to nonlinear boundary stipulations; this version is remodeled right into a pair of neutral-type time-delay equations which may conquer the complexity interested by the research and simulation of the partial differential equation model.

The moment half, research, is dedicated to the learn of the reaction of the approach defined via the time-delay version; very important houses worthy for examining approach balance are investigated and frequency- and time-domain suggestions are reviewed.

Part III, keep watch over, matters the layout of stabilizing keep watch over legislation aimed toward removing bad drilling vibrations; assorted keep an eye on concepts according to infinite--dimensional method representations are designed and evaluated. The keep an eye on proposals are proven to be potent in suppressing stick-slip and bit-bounce in order that a substantial development of the general drilling functionality might be achieved.

This self-contained e-book presents operational guidance to prevent drilling vibrations. in addition, because the modeling and keep watch over recommendations offered the following should be generalized to regard assorted engineering difficulties, it constitutes an invaluable source to researchers engaged on keep watch over and its engineering program in oil good drilling.
