    Laboratoryjne metody oceny trwałości stwardniałych zaczynów cementowych stosowanych do uszczelniania otworów wiertniczych
    (2007) Rzepka, Marcin; Stryczek, Stanisław
    The paper deals with laboratory methods of assessing durability of hardened cement slurries used for sealing drilling wells lie in evaluation of, e.g. strength parameters of hardened cement slurry, its porosity and gas permeability as well as the type of the formed microstructure. There are also presented exemplary results of analyses of hardened cement slurries obtained for samples long exposed to the simulated well conditions in highly mineralized waters and temperature 95-120 degrees of Celsius.
