腐植酸用作石油钻井泥浆助剂已有半个多世纪的历史,它的作用机理已逐步被人们所认识。而且随着石油勘探开发的不断发展,钻井液的生产工艺和产品质量也不断得到提高,以满足钻井的需要。 腐植酸是一种含有芳香环的无定形高分子化合物,用作泥浆有机处理剂,主要作用是降失水、稀释和页岩稳定剂,并且能耐高温, Humic acid has been used as an oil drilling mud additive for more than half a century and its mechanism of action has gradually been recognized. And with the continuous development of oil exploration and development, drilling fluid production technology and product quality are constantly being improved to meet the needs of drilling. Humic acid is an aromatic ring containing amorphous polymer compounds, used as a mud organic treatment agent, the main role is to reduce water loss, dilution and shale stabilizer, and can be high temperature,
