Abstract
A wellbore cement composition that includes a cross-linked polyamide. The polyamide is formed by reacting a di-functional amine with an aromatic tri-functional carboxylic acid. The wellbore cement composition is created by blending cement and water with the polyamide and then allowed to cure. Increases in compressive strength, Young's Modulus, and Poisson's Ratio of the cement are realized by adding the polyamide to the cement composition.
Claims12
A cement composition for use in a wellbore comprising:
- a cement comprising a calcium silicate;
- a polyamide compound that is cross-linked and formed by reacting an aromatic triacid chloride with an amine;
- and
- a bond between the wellbore and a tubular installed in the wellbore formed by injecting the composition into an annulus between the wellbore and the tubular.
