Oil well cement polycarboxylic acid dispersant and preparation method thereof
The invention discloses an oil well cement polycarboxylic acid dispersant and a preparation method thereof. The dispersant comprises the following components in parts by weight: 80-100 parts of unsaturated polyether monomer, 10-15 parts of unsaturated acid and salt thereof, 1-5 parts of unsaturated amide, 5-10 parts of viscosity modifier, 2-5 parts of pour point depressant, 0.5-2 parts of oxidant, 0.1-1 part of reducing agent and 0.1-0.5 part of chain transfer agent. The polycarboxylic acid dispersing agent can effectively solve the problems that an existing dispersing agent is large in pollution, high in toxicity, long in hydration time and incapable of being used in a severe cold environment.
本发明公开了一种油井水泥聚羧酸分散剂及其制备方法，该分散剂包括以下重量份的组分：不饱和聚醚单体80‑100份、不饱和酸及其盐10‑15份、不饱和酰胺1‑5份、粘度改性剂5‑10份、降凝剂2‑5份、氧化剂0.5‑2份、还原剂0.1‑1份和链转移剂0.1‑0.5份。该聚羧酸分散剂可有效解决现有的分散剂存在的污染大、毒性强、水化时间长、无法在严寒环境下使用的问题。
