Dispersing agent for oil well cement paste as well as preparation method and application of dispersing agent
The invention provides a dispersing agent for oil well cement paste as well as a preparation method and application of the dispersing agent. The dispersing agent for the oil well cement paste is prepared by polymerizing the following components in parts by weight: 20-40 parts of unsaturated polyether, 1-2 parts of unsaturated carboxylic acid, 1-2 parts of unsaturated ester and 0-2 parts of rigid unsaturated monomer. The dispersing agent for the oil well cement paste can improve the rheological property of the cement paste at the high temperature of 220 DEG C, has good compatibility with other cement paste additives, is beneficial to development of the strength of set cement, and can improve the abnormal gelling phenomenon of the high-temperature cement paste.
本发明提供了一种油井水泥浆用分散剂及其制备方法与应用。所述油井水泥浆用分散剂，按重量份数计算，其是由20‑40份不饱和聚醚、1‑2份不饱和羧酸、1‑2份不饱和酯、0‑2份刚性不饱和单体经聚合而得；该油井水泥浆用分散剂于220℃高温下能够提高水泥浆流变性能，与其他水泥浆外加剂配伍性能良好，利于水泥石强度发展，可改善高温水泥浆异常胶凝现象。
