Compound oil well cement fluid loss agent and preparation method thereof
The invention relates to the technical field of oil well operation admixtures, in particular to a compound oil well cement fluid loss agent and a preparation method thereof. The sulfonated styrene copolymer prepared by taking styrene, maleic anhydride and benzoyl peroxide as raw materials and the high-temperature-resistant liquid fluid loss agent prepared by taking itaconic acid, acrylamide and 2-acrylamido-2-methylpropanesulfonic acid as raw materials are blended, so that the effects of improving the comprehensive performance and expanding the application range are achieved; the sulfonated styrene copolymer has excellent dispersion, scale inhibition and water reduction performance, the high-temperature-resistant liquid fluid loss agent has excellent high-temperature resistance and water loss reduction performance, after the sulfonated styrene copolymer and the high-temperature-resistant liquid fluid loss agent are blended, the advantages of the sulfonated styrene copolymer and the high-temperature-resistant liquid fluid loss agent can be integrated, and the composite fluid loss agent with more comprehensive and excellent performance is formed. The fluid loss agent prepared by blending is matched with the temperature-resistant and salt-resistant polymer, so that the respective advantages of the three raw materials can be fully utilized, the waste of the raw materials is reduced, and the saving and efficient utilization of resources are realized.
本发明涉及油井作业外加剂技术领域，具体涉及一种复配型油井水泥降失水剂及其制备方法，本发明将以苯乙烯、马来酸酐和过氧化苯甲酰为原料制得的磺化苯乙烯共聚物与以衣康酸、丙烯酰胺和2‑丙烯酰胺基‑2‑甲基丙磺酸为原料制得耐高温液体降失水剂进行共混，具有提升综合性能、扩大适用范围的效果；磺化苯乙烯共聚物具有优异的分散、阻垢和减水性能，而耐高温液体降失水剂具有极好的耐高温和降失水性能，两者共混后，可以综合两者的优点，形成性能更为全面和优异的复合降失水剂，通过共混制备的降失水剂再与抗温耐盐聚合物互配，能够充分利用三种原料的各自优点，减少原料浪费，实现资源的节约和高效利用。
