    摘要： A method of cementing a wellbore comprising preparing a wellbore cementing composition comprising a cementitious materials and a modified biopolymer additive wherein the modified biopolymer additive is the reaction product of a process comprising contacting a biopolymer and an organic carbonate to form a reaction mixture and subjecting the reaction mixture to a temperature of from about 100° F. to about 250° F. and placing the wellbore cementing fluid in the wellbore. A method of cementing a wellbore comprising contacting a modified biopolymer additive with a cementitious slurry to produce a wellbore cementing composition having an initial viscosity, v0; placing the wellbore cementing composition to a desired depth in a subterranean formation wherein the wellbore cementing composition has a transitional viscosity, vt, during placement in the subterranean formation and a final viscosity, vf, at the desired depth wherein vf≧vt>v0; and allowing the wellbore cementing composition to set.

    摘要： According to an embodiment, a composition is provided that can be used in a cementing. The composition includes at least: (i) a hydraulic cement; and (ii) a copolymer comprising at least the monomeric units (a) through (d) of formula (A); (a) A = H, B = H, CH
    3 (or) A = COOH, B = H, CH
    2 , (b) D = -NH-C(CH

    2 -OH, -CH
    2 -CH(CH
    3 )-OH, wherein the monomeric units (a) through (d) can be any sequence and any proportion in the copolymer. With water, the composition of the hydraulic cement and such a copolymer becomes a cement composition. According to the method, the cement composition is introduced into a well and allowed to set in the well.
