Abstract
This study aims to characterize a new type of cement, produced from the mixture of common Portland cements, which could be used as an option in the cementing of oil wells. To enable this study a linear programming method was used for the composition of the new cement, then, characterization tests were performed through particle size analysis by laser diffraction, chemical analysis by EDX, thermogravimetric analysis, X-ray diffraction, setting time, compressive strength. The results allowed the conclusion that the new formulated cement presented low C3A content, time setting superior to the Portland Cement for Oil Well, thermal stability up to 500 °C, low hydration kinetics and content of the main components coherent to the ABNT specifications.
