利用乙烯吡咯烷酮、马来酸酐、2-丙烯酰胺-2-甲基丙磺酸以及烯丙基三乙氧基硅烷改性纳米二氧化硅进行共聚反应,研发出一种耐温纳米聚合物固井水泥缓凝剂NPDS11,并采用傅里叶红外光谱分析、热重分析、高温缓凝试验、固化后水泥石强度试验研究NPDS11 的分子结构以及缓凝效果.结合共聚物分子结构特征分析其高温缓凝机理,并试验了其与地层流体的配伍性.研究结果表明,研发的耐温纳米聚合物固井水泥缓凝剂耐温可达190℃,且与其他化学助剂具有良好配伍性.
Development and evaluation of high-temperature resistant nano polymer cementing cement retarder
The vinylpyrrolidone,maleic anhydride,2-acrylamide-2-methylpropane sulfonic acid and allyl group triethoxysilane are used to modify nano silica for copolymerization,and a high-temperature resistant nano polymer cement retarder NPDS11 is developed.The molecular structure and retarding effect of NPDS11 are studied by Fourier infrared spectroscopy,thermogravimetric analysis,high-temperature retarding test and strength test of solidified cement.Combined with the molecular structure characteristics of the copolymer,its high-temperature retarding mechanism is analyzed,and its compatibility with formation fluids is experimentally analyzed.A series of studies have shown that the developed temperature resistant nano polymer cementing cement retarder can withstand temperatures up to 190℃and has good compatibility with other chemical additives.
