CROSS-LINKED POLYROTAXANES AND THEIR APPLICATION IN CEMENT
This document relates to methods for preventing or inhibiting the formation of micro-cracks and fractures in the cement of an oil well using cement compositions that contain cross-linked polyrotaxane additives. The cement compositions containing the cross-linked polyrotaxane additives exhibit increased stiffness without suffering a decrease in compressive strength, as compared to the same cement without the cross-linked polyrotaxane additive.
Ce document concerne des procédés de prévention ou d'inhibition de la formation de microfissures et de fractures dans le ciment d'un puits de pétrole mettant en oeuvre des compositions cimentaires qui contiennent des additifs polyrotaxanes réticulés. Ces compositions cimentaires contenant les additifs polyrotaxanes réticulés offrent une rigidité accrue sans diminution de la résistance à la compression, par rapport au même ciment sans cet additif polyrotaxane réticulé.
