腐植酸盐在钻井泥浆调整剂上的应用,在国内外已有二十多年的历史。五十年代日本在北海道钻井时,通过在泥炭层泥浆性能变好,发现腐植酸可以调整泥浆的性能。从而生产腐植酸盐做泥浆的稳定剂和稀释剂。国内最初使用的是煤碱剂,一般是在钻井现场用褐煤、风化煤粉加适量烧碱和水配制而成。主要还用作降失水剂。但是由于腐植酸本身的性质不同与制配技术的差异,使煤碱 The application of humic acid salt in drilling mud regulator has more than twenty years of history both at home and abroad. In the 1950s when Japan drilled wells in Hokkaido, it was found that humic acid can adjust the performance of mud through better mud performance in the peat layer. Producing humic acid salt to make mud stabilizer and diluent. Originally used in the country is a coal-based agent, generally at the drilling site with brown coal, weathered coal plus appropriate amount of caustic soda and water preparation. Mainly used as a fluid loss agent. However, due to the nature of humic acid itself and the difference between the system of making technology to make coal-based
