前言国内外对腐植酸的研究已有二百年历史。腐植酸类物质在农、工、医、牧及环保等各方面已得到了广泛使用。腐植酸盐是钻井泥浆处理剂的重要类型。腐钾(KHm)经过地质勘探与石油钻井现场的广泛使用,证明它有调节泥浆流变性、降失水、抑制粘土水化膨胀,防井塌与抗高温的良好效果。是一种优良的泥浆降失水剂、防塌剂及高温稀释剂(降粘、降切)。
Preface The study of humic acid at home and abroad have two hundred years of history. Humic acid substances have been widely used in agriculture, industry, medicine, animal husbandry and environmental protection. Humic acid salts are an important type of drilling mud treatment agent. KHm has been used extensively in geological prospecting and oil drilling sites to prove its good effect of regulating the rheology of mud, reducing water loss, inhibiting hydration and expansion of clay, preventing well collapse and resisting high temperature. Is an excellent mud fluid loss agent, anti-collapse agent and high temperature thinner (viscosity, cut).
