Evaluation of thermal conductivity of the plugging material cement stone based on magnesia cement for cementing casing columns, overlaping permafrost sediments

Authors: A.M. Pastukhov, G.M. Tolkachov (Perm National Research Polytechnic University, RF, Perm)

Key words: cementing casing columns, permafrost, magnesia cement, cement stone, thermal conductivity.

The results of laboratory studies of thermal conductivity of cement stone of plugging materials based on magnesia cement, designed for cementing casing columns, overlaping permafrost sediments, are given. The influence of various additives on the thermal conductivity of cement stone is established by the executed works.
