Read e-book online Analysis and Control of Oilwell Drilling Vibrations: A PDF

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

This e-book stories the result of exhaustive learn paintings on modeling and regulate of vertical oil good drilling structures. it really is concerned about 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, provides lumped- and distributed-parameter types that permit the dynamic habit of the drill string to be characterised; a accomplished mathematical version bearing in mind mechanical and electrical parts of the final drilling process is usually supplied. The disbursed nature of the process is accommodated by way of contemplating a process of wave equations topic to nonlinear boundary stipulations; this version is reworked right into a pair of neutral-type time-delay equations which may conquer the complexity occupied with 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; vital homes worthy for reading method balance are investigated and frequency- and time-domain recommendations are reviewed.

Part III, regulate, matters the layout of stabilizing keep an eye on legislation geared toward casting off bad drilling vibrations; different regulate ideas in keeping with infinite--dimensional procedure 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 will be achieved.

This self-contained ebook offers operational instructions to prevent drilling vibrations. additionally, because the modeling and keep watch over innovations offered right here could be generalized to regard diversified engineering difficulties, it constitutes an invaluable source to researchers engaged on keep watch over and its engineering program in oil good drilling.
