| Sammanfattning: | 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 |
