摘要： A method of servicing a wellbore that penetrates a subterranean formation includes displacing a cement composition comprising an aromatic sulfonated polymer into the wellbore and allowing the cement composition to set. In an embodiment, a transition time of the cement composition is less than or equal to about 60 minutes, alternatively less than or equal to about 50 minutes, less than or equal to about 40 minutes, less than or equal to about 30 minutes, less than or equal to about 20 minutes, or less than or equal to about 10 minutes. Thus, the transition time may be short enough to inhibit a substantial amount of gas migration into the cement composition before it sets. In yet another embodiment, the cement composition exhibits a viscosity that increases from a value of 35 Bc (Bearden units) to about 100 Bc in about 10 minutes or less when the cement composition sets.

摘要： Methods of retarding the setting of a cement composition comprise including one or more secondary amines substituted with a carboxyl group or salts thereof (e.g., 3-hydroxy N,N′-iminodisuccinic acid) in the cement composition. The inclusion of such materials in cement compositions may be highly beneficial. In wellbores having BHCT's of less than or equal to about 250° F., the use of the secondary amine as the set retarder ensures that the thickening time of the cement composition is sufficient to allow the cement composition to be pumped to its desired downhole location. Further, the secondary amine may be used in combination with conventional set retarders to enhance the ability of those retarders to increase the thickening time of the cement composition at higher BHCT's, e.g., from about 250° F. to about 525° F.
摘要翻译：阻止水泥组合物凝固的方法包括在水泥组合物中包括一个或多个被羧基取代的仲胺或其盐（例如3-羟基N，N'-亚氨基二琥珀酸）。将这些材料包含在水泥组合物中可能是非常有益的。在具有小于或等于约250°F的BHCT的孔筒中，使用仲胺作为凝结缓凝剂确保了水泥组合物的增稠时间足以使水泥组合物被泵送到其所需的井下位置。此外，仲胺可以与常规固化缓凝剂组合使用，以增强这些缓凝剂在较高BHCT下例如约250°F至约525°F时增加水泥组合物的增稠时间的能力。
