Previous issue date: 2016-10-04 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / A ind?stria da constru??o civil emprega uma grande diversidade de aditivos desenvolvidos
para uso em concretos e argamassas e que apresentam excelente desempenho na modifica??o
do comportamento do cimento Portland. Algumas dessas propriedades encontram fun??es
an?logas ou similares na engenharia de po?os de petr?leo, como por exemplo, os
antiespumantes, dispersantes ou redutores de fric??o, controladores de filtrado e retardadores
de pega. Este estudo foi desenvolvido com o objetivo de avaliar e especificar produtos
qu?micos alternativos para compor sistemas de aditivos adequados ? formula??o de pastas de
cimento para aplica??o em po?os de petr?leo onshore caracterizados por temperaturas a partir
de 180?F (82?C), po?os depletados e po?os sujeito ? inje??o de vapor. Durante o per?odo de
execu??o do estudo, foram selecionados produtos qu?micos de acordo com sua fun??o. Estes
produtos foram especificados segundo normas internas da Petrobras e os testes foram
realizados de acordo com a norma API RP 10B. Alguns dos aditivos apresentaram grande
potencial para aplica??o em pastas de cimento para temperaturas elevadas, incluindo
antiespumantes, controladores de filtrado, dispersantes e retardadores de pega. / The civil construction industry employs a wide diversity of admixtures developed to
use in concrete and mortars, but that exhibits excellent performance for oilwell slurries. Some
properties meet analogous functions, for example, antifoam, dispersants or friction reducers,
fluid loss control agent and set retarders. This study was developed with the objective to
evaluate and specify alternative chemical products to be used as admixtures for the
formulation of cement slurries for application in onshore oil wells, characterized by
temperatures of 180?F (82?C), mature wells and wells subjected to steam injection. During
the study, chemical products were selected according its functions. These additives were
specified according to PETROBRAS internal standards and the tests were realized according
to API RP 10B standards. Some additives presented great potential for application in cement
slurries for high temperatures, including antifoams, fluid loss control agents, dispersants and
setting retarders.
