五十年代日本犬养等首先将褐煤硝酸氧解产物用于钻井泥浆处理剂。六十年代苏联的巴布科娃等人也发表了类似研究报导。以后日本、美国等对褐煤HNO_3氧化产物改性用于泥浆处理剂的研究报告、专利等引起世界许多国家同仁者的兴趣和重视。腐植酸用于钻井泥浆处理剂历久不衰的一个重要原因就是由于它具有原料来源广、生产工艺简便、成本低,尤其热稳定性要比其它天然或合成高分子制得的处理剂高出一筹,同时兼有高温稀释及降滤失效果好等特点,至今仍是世界许多国家石油钻井泥浆处理剂中抗高温的一个重要品种。
In the fifties, Japanese kennels and others first used lignite nitrate oxygenate for drilling mud treatment agents. In the 1960s, Babukova of the Soviet Union also published similar research reports. After Japan, the United States and other research on the modification of lignite HNO_3 oxidation products for mud treatment agent research, patents and other countries in the world have aroused the interest of colleagues and attention. Humic acid drilling mud treatment for a long time, an important reason is because it has a wide source of raw materials, the production process is simple, low cost, in particular, thermal stability than other natural or synthetic polymer treatment agent outshone At the same time, it has the characteristics of high temperature dilution and good filtration loss, and so far it is still an important heat-resistant species in oil drilling mud treatment agents in many countries.
