Low-density cement paste suspending agent and preparation method thereof
The invention relates to a low-density cement paste suspending agent which comprises the following components in parts by weight: 100 parts of 2-acrylamide-2-methylpropanesulfonic acid; 5-10 parts of a temperature-sensitive monomer; 1-3 parts of a molecular weight regulator; 8 to 10 parts of an amide monomer; 0.5 to 1.0 part of a carboxylic acid monomer; and 300 to 400 parts of water. The low-density cement slurry suspending agent has the advantages that the low-density cement slurry suspending agent is especially suitable for a low-density cement slurry system, and low-density cement slurry prepared from the low-density cement slurry suspending agent has the characteristics of high cement discharging speed, good rheological property at low temperature, good suspension stability at high temperature and the like, has good comprehensive performance, and can effectively guarantee the safety of well cementation construction and improve the well cementation quality.
本发明涉及一种低密度水泥浆悬浮剂，包括如下重量份的组分：2‑丙烯酰胺‑2‑甲基丙磺酸，100份；温敏单体，5~10份；分子量调节剂，1‑3份；酰胺类单体，8‑10份；羧酸类单体，0.5~1.0份；水，300~400份。本发明的优点是，该低密度水泥浆悬浮剂特别适用于低密度水泥浆体系，用其配制低密度水泥浆具有下灰快、低温下流变性能好、高温下悬浮稳定性佳等特性，综合性能良好，可有效保障固井施工安全，提高固井质量。
