Dissertação (Mestrado em Engenharia Elétrica e da Computação) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/6486The purpose of this work is to calculate the Surge and Swab geopressures inside eccentrics wells. There is eccentricity between the drill string and the well. The traditional theory to calculate these geopressures considers that the drill string and the well remain concentric throughout the process, which does not occur in reality. The analysis of this phenomenon is carried out, in which the fluid is confined between the two cylinders, the drill string and the well. The conformal mapping are used to transform the eccentric domain in concentric domain and thus find the real values of geopressures. The results obtained using the proposed methodology are presented and discussed.application/pdfAcesso AbertoTransformações conformesPerfuração de poçosConformal mappingWell drillingENGENHARIAS::ENGENHARIA ELETRICADissertação
