本研究首次将有机硅引入到腐植酸中，并利用二氧化硅改性材料（以TSP-L12)、腐植酸钠(NaHm)、2-丙烯酰氨基-2-甲基丙磺酸钠(AMPS)、丙烯酰胺(AM)为原料。对HASSi的分子结构、化学组成进行了研究，结果表明HASSi的化学结构符合分子设计。差示扫描量热-热重分析结果表明，HASSi在氮气下的热分解温度为250℃。通过耐温评估，HASSi可以承受高达230°C的温度。耐盐、耐钙性能评价证实其耐氯化钠可达5%，耐氯化钙_可达0.5%。通过扫描电镜分析HASSi水溶液、滤饼微观结构、zeta电位测量、粒度分布等多种方法研究了HASSi的滤液减少机理，结果表明HASSi参与了泥饼的形成，并说明了HASSi的滤液减少机理。优良的降滤失效果。此外，HASSi通过环境性能评价被认定为环保型降滤失剂，在油田显示出巨大的应用前景。

Synthesis and mechanism study of an environmentally friendly filtrate reducing agent from humic acid and organic silicon

In this study, organic silicon was introduced to humic acid for the first time, and set the novel polymer NaHm/AMPS/AM/TSP-L12 (HASSi) as an environmentally friendly filtrate reducing agent, which was developed by using silica modified material (TSP-L12), sodium humic acid (NaHm), 2-acrylamido-2-methylpropanesulfonic acid sodium (AMPS), and acrylamide (AM) as raw materials. The molecular structure, chemical composition of HASSi has been investigated and results show that HASSi shows the chemical structure was conformed to the molecular design. Differential scanning calorimetry–thermogravimetric analysis results illustrate that thermal decomposition temperature of HASSi under nitrogen was 250°C. Though temperature resistance evaluations, HASSi could withstand temperature up to 230°C. Salt and calcium resistance evaluations confirmed its resistance of NaCl could reach up to 5% and CaCl₂ to 0.5%. The filtrate reduce mechanism of HASSi was investigated through various methods, including scanning electron microscope analysis of HASSi aqueous solution, microstructure of filter cake, measurements of zeta potential, and particle size distribution, results showed that HASSi participation in the formation of mud cakes and illustrated an excellent filtration reduction effect. In addition, HASSi was identified as an environmentally friendly filter loss reducing agent through environmental performance evaluation, which shows a great application prospect in oilfield.
