Rheological models of saline sealing slurries with fly ashes content

Authors: S. Stryczek, R. Wiśniowski

The criteria which should be taken into consideration when selecting scaling slurries based on fly ashes tor injection operations in a saline rock mass arc presented in this paper. Cement-ash cements arc analysed and tabulated qualitatively.

The results of laboratory analyses aiming at establishing the rheologieal parameters of the scaling slurries are also included.

The principles for the selection of a rheologieal model of the slurry arc discussed and the relevant relationships influencing this the selection arc given.

Based on the results, the physico-chemical effects taking place in the saline scaling slurries were analysed.

Later in the paper the influence of these processes on the rheologieal properties is explained.

Additionally, principles for the calculation of resistivity to flow of slurries arc put forward, accounting for the selection of an optimum rheologieal model for each analysed recipe.

The results and an exemplary simulation arc highlighted in the conclusion.
