Fluid loss agent suitable for aluminate cement paste and preparation method offluid loss agent
The invention relates to a fluid loss agent suitable for aluminate cement paste and a preparation method of the fluid loss agent. The fluid loss agent comprises an agent A and an agent B. The agent Ais a quadripolymer formed by polymerizing N-(3-dimethylaminopropyl) methacrylamide, methacryloyloxyethyl trimethyl ammonium chloride, 2-acrylamido-2-methyl propanesulfonic acid and acrylic acid through a free radical aqueous solution; and the agent B is titanium dioxide. The preparation method comprises the following steps of: mixing the agent A and the agent B according to a mass ratio of 5-10: 1; carrying out crushing and surface modification; carrying out microwave surface treatment, filtering, and drying to obtain the fluid loss agent. The preparation method is reliable in principle and easy and convenient to operate; the prepared fluid loss agent can effectively control the water loss of aluminate cement paste, and the fluid loss agent is suitable for heavy oil thermal recovery well cementation engineering and has a bright market application prospect.
本发明涉及一种适用于铝酸盐水泥浆的降失水剂及其制备方法。该降失水剂包括甲剂和乙剂，甲剂为由N‑（3‑二甲氨基丙基）甲基丙烯酰胺、甲基丙烯酰氧乙基三甲基氯化铵、2‑丙烯酰胺基‑2‑甲基丙磺酸和丙烯酸通过自由基水溶液聚合而成的四元共聚物，乙剂为钛白粉，将甲剂与乙剂按照5~10:1的质量比混合后，进行粉碎和表面改性，再进行微波表面处理、过滤、烘干而成降失水剂。本发明原理可靠，操作简便，制备的降失水剂可以有效控制铝酸盐水泥浆的失水量，适用于稠油热采井固井工程，具有广阔的市场应用前景。
