摘要
实验以褐煤为原料,通过与尿素、甲醛和苯酚反应制得酚脲醛树脂,经磺化剂磺化制得抗温、抗盐性能较好的钻井泥浆降滤失剂。对该降滤失剂的流变参数、老化性能和抗盐性能等方面进行了测试。结果表明,该降滤失剂的室温降黏率>70%,室温中压滤失量<10mL,老化后高温高压滤失量<15mL,在质量分数4%的盐水浆中,180℃老化后,4%盐水基浆中压降滤失量<10mL,高温高压降滤失量<20mL,其性能符合Q/SH 1020 1881—2008标准。
A fluid loss reducer was obtained with excellent temperature and salt tolerance through modifying lignite with phenolic urea-formaldehyde resin. A series of tests were carried out on the rheological parameters, aging performance and salt tolerance. The fluid loss reducer showed viscosity reduction rate 〉70 % at room temperature and medium pressure filtration 〈 10 mL, high temperature and high pressure filtration 〈 15 mL after aging experiment at 180 ℃ ; with 40% NaCl slurry, the medium pressure filtration 〈 10 mL, the high temperature and high pressure filtration 〈 20 mL after ageing experiment. The excellent properties demonstrated by the experiments meet the standards of Q/SH 1020 1881--2008.
