摘　　要：以木质素磺酸钙为主要原料 ,通过甲醛缩合、接枝共聚、金属络合及磺化处理等一系列改性反应 ,在室内制备了新型钻井液降粘剂 PNK,室内流变性、抗温性、抗盐污染能力以及抑制性评价实验及现场应用结果表明 ,其性能优于国内外同类产品 ,具有较强的抗高温、抗盐污染能力和抑制性 ,是一种能显著降低水基钻井液粘度。Using Ca LS as the main raw materials and through a series of modification reactions, such as condensation reaction with formaldehyde, graft copolymerization, metal complexation and sulfontion, a new lignin type drilling fluid additive, PNK, is developed under laboratory conditions. Meanwhile, PNK is evaluated on its rheology, temperature resistance and salt resistance in laboratory. The results show that the additive can improve well stability and ROP.
