| 中文摘要:以丙烯酸（AA）、N,N-二甲基丙烯酰胺（DMAA）、2-丙烯酰胺基-2-甲基丙磺酸（AMPS）、丙烯酰胺（AM）、对苯乙烯磺酸钠（SSS）等为原料合成油井水泥降失水剂，并对该新型油井水泥降失水剂配置的水泥浆综合性能进行室内试验评价。结果表明水泥浆中加入该降失水剂可以控制API滤失量在50 mL以内,抗温达180 ℃。降失水剂使水泥浆的抗析水能力增强,稠化时间略有延长；抗盐能力达到36%。值得进一步推广应用。 |

| Abstract:A new fluid loss additive for oil well cement was synthesized with acrylic acid (AA), n, n-dimethylacrylamide (DMAA), 2-acrylamide-2-methyl propane sulfuric acid (AMPS), acryl amide (AM), and sodium p-styrenesulfonate (SSS）, the comprehensive performance of cement slurry prepared by the new oil well cement fluid loss additive was evaluated by laboratory test. The results show that the cement slurry filtration can be controlled within 50 ml according to API measurement standard by adding this fluid loss additive and the temperature tolerance is up to 180℃. With the improved water separation resistance, longer thickening time and 36% saline tolerance, this fluid loss additive should be further widely used. |
