“…On the other hand, improve zonal isolation in the annulus between the casing and the formation of an oil well, has been and continues to be the main reason to develop new technologies. In the 70's work began to convert water-based drilling fluids using granulated blast furnace slag as addition, from this moment several investigations have been made to optimize this technology [4][5][6]. Numerous studies suggest the use of a universal drilling fluid containing granulated blast furnace slag as addition (between 25 and 35 %); after which it has initiated the use of cement slurries with a variable percentage of granulated slag replacement (between 20 and 40%) [7,8].…”

In this work, they were produced and characterized cementing composites made with blast furnace slag replacement, for their use in the construction of oil wells. To this, slurries were prepared with a replacement of 20 and 30% slag, as well as a slurry with 100 % slag and a slurry with 100% H-cement were prepared. Starting materials were characterized by chemical analysis, X-ray diffraction and Fourier Transformed Infra Red. Slurries also were activated with sodium silicate in order to study theirs hydration kinetics, driving by isothermal calorimetry. These studies were complemented by the preparation of specimens of 4 X 4 X 16 cm to which they determine its compressive and bending strength during 2 and 28 days of curing. From the results it can be concluded that it was obtained a product that can be effectively used in the construction of oil wells.
