Cross-linking agent, micro-crosslinking type polycarboxylic acid dispersing agent and corresponding preparation methods of cross-linking agent and micro-crosslinking type polycarboxylic acid dispersing agent
The invention relates to the technical field of oil field development well cementation operation, in particular to a cross-linking agent, a micro-cross-linking type polycarboxylic acid dispersing agent and a corresponding preparation method, divinyl carboxylic acid-beta-cyclodextrin diester is added during synthesis, the formed micro-cross-linking type polycarboxylic acid dispersing agent can obtain better dispersing performance, and meanwhile, the dispersing performance of the micro-cross-linking type polycarboxylic acid dispersing agent is improved. The cross-linking between the polymers can improve the temperature resistance. According to the cross-linking agent, the micro-cross-linking type polycarboxylic acid dispersing agent and the corresponding preparation method, the problems that a conventional polycarboxylic acid water reducing agent can inhibit hydration of cement when being applied to oil well cement, development of early strength of set cement is not facilitated, and the dispersing performance at high temperature is poor can be solved.
本发明涉及油田开发固井作业技术领域，特别是涉及一种交联剂、微交联型聚羧酸分散剂以及相应的制备方法，合成时加入二乙烯基羧酸‑β‑环糊精二酯，形成的微交联型聚羧酸分散剂可以获得更好的分散性能，同时，聚合物之间的交联可以提高其抗温能力。通过本交联剂、微交联型聚羧酸分散剂及相应制备方法，能解决常规聚羧酸减水剂应用于油井水泥中会抑制水泥的水化、不利于水泥石早期强度发展以及高温下分散性能较差等问题。
