摘要: 深井超深井井底温度高,水泥浆滤失控制难度大。为解决这一问题,以 2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、丙烯酰胺(AM)和苯乙烯磺酸钠(SSS)为原料,以偶氮二异丁脒盐酸盐为引发剂,通过优化AMPS、AM和SSS三者的比例,合成了三元共聚耐高温降滤失剂AAS。利用红外光谱、核磁共振氢谱表征、热重和差热分析等方法评价了AAS的稳定性,并开展了水泥浆高温滤失性能评价。结果表明,AMPS、AM和SSS质量比为20:5:1时,AAS的分解温度为350℃左右;AAS加量为1.6%时,在180℃条件下水泥浆API滤失量可以控制在150 mL以下,150℃条件下滤失量为56 mL。研究表明,降滤失剂AAS能够降低水泥浆在高温下的滤失量,对水泥浆流变性、强度和稠化时间无明显影响,能满足高温固井对水泥浆的要求。Abstract: With high bottom hole temperatures in deep and ultra deep wells, there are difficulties in mud filtration control. The study on high temperature resistant polymer fluid loss agent was done in which 2-acrylamido-2-methyl propane sulfonic acid (AMPS), acrylamide (AM) and sodium styrene sulfonate (SSS) were used as raw materials and azo diisobutyl amidine hydrochloride as the initiator. The proportion of AMPS, AM and SSS was optimized to obtain terpolymers through chemical reaction. Then the synthetic products were extracted, dried and crushed with acetone to produce ternary copolymerization fluid loss agent, AAS. High-temperature cement slurry filtration performances were evaluated by using infrared spectroscopy, nuclear magnetic resonance hydrogen spectrum characterization, thermogravimetric and differential thermal analysis to determine the stability of these synthetic products. Research results showed that the synthetic copolymer decomposition temperature was 350℃ when the mass ratio of AMPS,AM and SSS was 20:5:1; API cement slurry filtration could be controlled under 150 mL at 180℃ when the dosage of copolymer was increased by 1.6%. At 150℃, the filtration was 56 mL. The research showed that the ternary copolymer fluid loss agent AAS could significantly improve the filtration control ability of the cement slurry at high temperatures. In addition, the ternary copolymer fluid had no obvious effect on rheological properties, strength and thickening time of the cement slurry, so that it could meet the technical requirements for high-temperature cementing slurry.
