前言腐植酸类泥浆处理剂经过石油钻井和岩心钻探的几十年广泛的应用和广大科技人员的研究试验,证明它是一类优良的泥浆处理剂,它具有较好的降失水作用(特别是一些改性或和聚合物共聚、复配或化学处理的产品)、稀释降粘作用、防塌作用(特别是引入钾、铵离子的处理剂)、高温稳定作用,而且它也具有一定的抗盐、抗钙的能力,特别是一些和聚合物共聚、复配或化学处理的产品具有很高的抗盐、抗钙等抗污染的能
Foreword humic acid mud treatment agent through petroleum drilling and core drilling decades of extensive application and research scientists, proved that it is a class of excellent mud treatment agent, it has a good loss of water (especially Is some modified or polymer copolymerization, compounding or chemical treatment products), dilute viscosity reduction, anti-collapse effect (especially the introduction of potassium, ammonium ion treatment agent), high temperature stability, and it also has a certain Anti-salt, anti-calcium ability, especially with some polymers copolymerization, compounding or chemical treatment of products with high resistance to salt, anti-calcium and other anti-pollution energy
