一、前言腐植酸盐由于来源广,研制工艺较简易,价格较低廉,已广泛应用做为泥浆处理剂,效果良好。随着石油工业的发展,钻井深度加深,含盐地层复杂,对泥浆的性能的要求越高,尤其需要具有降失水、稀释、防塌、抗温又抗盐的处理剂。研制有良好抗盐能力的泥浆处理剂已成为当前油田和地质勘探的重要课题。 First, the introduction of humic acid salt due to a wide range of sources, the development process is simpler, cheaper, has been widely used as a mud treatment agent, the effect is good. With the development of petroleum industry, drilling depth is deepened, salt formation is complex, and the requirement for mud performance is higher. In particular, it needs a treatment agent that reduces water loss, dilution, anti-collapse, heat resistance and salt resistance. The development of a mud treatment agent with good salt resistance capability has become an important issue in current oilfields and geological exploration.
