Investigation of Nano-Silica Solution Flow through Cement Cracks

Cement cracks are one of the most common failures in oil and gas wells. Cracks can reduce cement strength, resulting a loss zonal isolation fluid leak. Placement gels nanoparticles (NPs) is considered as promising solution to solve problem. It highly desirable know if flow behavior NPs solutions predictable when they squeezed into cracks. Experimental tests were performed this study investigate nano-silica ducts cross-sections rectangular shape. The linear relationship between rate pressure gradient calculated Reynolds number values suggests laminar ducts. However, Hagen–Poiseuille correlation for does not describe solution. classic hydraulic model with diameter describes an average error 12.38%. cause discrepancies models measured data known. be attributed NPs–NPs frictions NPs–wall rough that models.
