摘要： Cement compositions comprising carboxylated inulin and methods of using the same to cement a workspace. In one embodiment, a method of cementing includes providing a cement composition comprising a carboxylated inulin, for example, in a subterranean formation. The method further includes allowing the cement composition to set. In some embodiments, the cement composition has a thickening time of from about 2 hours to about 11 hours. In other embodiments, the cement composition has a viscosity that is about constant for a period of time after the cement composition is placed.

摘要： A method of cementing a wellbore comprising preparing a cement composition comprising a water-soluble aromatic sulfonated polymer, and placing the cement composition into the wellbore, wherein the cement composition develops a compressive strength of greater than about zero in less time than a similar cement composition having a comparable thickening time and lacking a water-soluble aromatic sulfonated polymer. A cement composition comprising a water-soluble aromatic sulfonated polymer, wherein the cement composition develops a compressive strength of greater than about zero in less time than a similar cement composition having comparable thickening time and lacking a water-soluble aromatic sulfonated polymer.
