Get Analysis and Control of Oilwell Drilling Vibrations: A PDF

By Martha Belem Saldivar Márquez,Islam Boussaada,Hugues Mounier,Silviu-Iulian Niculescu

This booklet experiences the result of exhaustive learn paintings on modeling and regulate of vertical oil good drilling platforms. it's interested by the research of the system-dynamic reaction and the removing 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 permit the dynamic habit of the drill string to be characterised; a finished mathematical version taking into consideration mechanical and electrical parts of the general drilling process is usually supplied. The dispensed nature of the process is accommodated by way of contemplating a procedure of wave equations topic to nonlinear boundary stipulations; this version is remodeled right into a pair of neutral-type time-delay equations that can conquer the complexity fascinated 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 through the time-delay version; vital houses beneficial for examining process balance are investigated and frequency- and time-domain strategies are reviewed.

Part III, regulate, matters the layout of stabilizing keep an eye on legislation aimed toward casting off bad drilling vibrations; assorted keep watch over suggestions in response 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 should be achieved.

This self-contained publication offers operational directions to prevent drilling vibrations. additionally, because the modeling and regulate innovations provided right here will be generalized to regard assorted engineering difficulties, it constitutes an invaluable source to researchers engaged on regulate and its engineering software in oil good drilling.
