This publication studies the result of exhaustive examine paintings on modeling and regulate of vertical oil good drilling platforms. it truly is all for the research of the system-dynamic reaction and the removal of the main destructive 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, offers lumped- and distributed-parameter versions that let the dynamic habit of the drill string to be characterised; a complete mathematical version considering mechanical and electrical parts of the final drilling procedure is usually supplied. The allotted nature of the method is accommodated by means of contemplating a process of wave equations topic to nonlinear boundary stipulations; this version is remodeled right into a pair of neutral-type time-delay equations that may conquer the complexity inquisitive about the research and simulation of the partial differential equation model.

The moment half, research, is dedicated to the learn of the reaction of the method defined by means of the time-delay version; very important houses important for reading approach balance are investigated and frequency- and time-domain innovations are reviewed.

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

This self-contained publication presents operational guidance to prevent drilling vibrations. in addition, because the modeling and regulate suggestions awarded right here will be generalized to regard various engineering difficulties, it constitutes an invaluable source to researchers engaged on keep an eye on and its engineering program in oil good drilling.
