Abstract
Adequate slurry design is critical to the success of a cementing work. In this study, a ball mill procedure was used to prepare a nano powder from a fly ash material supplied by Al-kufa Cement Factory for re-inforcing the oil well cement through using it as a partial replacement of oil well cement class G by a weight percentage of(0.25%,0.5%, 0.75% and1%)and micro fiber polypropylene at percentage (0.25%,0.5%,0.75%,and 1%).The mix with a water to cement ratio was made at 0.44.Characterizations of the prepared samples were conducted by X-Ray Diffraction (XRD), Atomic Force Microscope (AFM), density and compressive strength. The results manifested that the structural properties were improved with the development of calcium silicate hydration (C-S-H)phase, the density as well as the enhancement in compressive strength. That makes it proper for the oil well applications.
