Previous issue date: 2012-07-25 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Grautes are dry mixes with hydraulic characteristics widely used in construction. This
material comprises cement, mineral additives and dosed in accordance with the desired
properties. The use of grautes in cementing oil wells potentially increases the precision in the
composition of the mixture, since it is requires only the addition of the mixing water before its
pumping. Such benefit may be availed in cementing wells since the formulations grautes meet
the temperature and pressure characteristics typical of wells. The objective of this study is to
evaluate the effect of adding different percentages of industrial minerals properties of light
grautes for onshore oil wells. For the formulation of the employees were grautes light
industrial minerals and waste minerals abundant in the Northeast, in addiction to Portland
cement and chemical additives Special class. Grautes were formulated with densities between
1.55 g/cm3 (13.0 lb/gal) and 1.68 g/cm3 (14 lb/gal). Tests results showed that grautes with
higher density in the range studied meet the specifications for cementation of shallow wells
onshore. The compositions lighter can also be adjusted for applying the material in the
cementation of oil wells / Grautes s?o misturas secas com caracter?sticas hidr?ulicas amplamente empregadas na constru??o
civil. Este material ? constitu?do por cimento, minerais e aditivos dosados de acordo com as
propriedades desejadas. A utiliza??o de grautes na cimenta??o de po?os de petr?leo potencialmente
incrementa a precis?o na composi??o da mistura, uma vez que ? necess?ria apenas a adi??o da
?gua de mistura antes de seu bombeio. Tal benef?cio pode ser aproveitado na cimenta??o de po?os
desde que as formula??es de grautes atendam ?s caracter?sticas de temperatura e press?o t?picas
dos po?os. O objetivo deste trabalho ? avaliar o efeito da adi??o de diferentes percentuais de
minerais industriais nas propriedades de grautes leves para po?os de petr?leo onshore. Para a
formula??o dos grautes foram empregados minerais industriais leves e res?duos minerais abundantes
na regi?o Nordeste, al?m de cimento Portland classe Especial e aditivos qu?micos. Foram formulados
grautes com densidades entre 1,55 g/cm3 (13,0 lb/gal) e 1,68 g/cm3 (14,0 lb/gal). Foram realizados
ensaios de compacidade, reologia e controle de filtrado. Os resultados mostraram que os grautes que
apresentam maior densidade na faixa estudada atendem ?s especifica??es para cimenta??o de
po?os rasos onshore. As composi??es mais leves podem, tamb?m, ser ajustadas para a aplica??o do
material na cimenta??o de po?os de petr?leo
