摘　　要：用动力学方法研究了磺化甲基酚醛树脂（Ⅰ）在钻井液中的降解机理，发现其降解机理随着温度的变化6不同，并由红外光谱、13C核磁共振谱及紫外光谱对其降解机理加以解释，且拟合出连续一级降解的动力学失水方程，得出了磺化甲基酸醛树脂（Ⅰ）在钻井液中的失效最高温度。The degradation mechanism of sulphonated methyl phenolic resin (Ⅰ) in drilling fluids is studied with kinetic method. Result shows that the mechanism of degradation is different with the change of aging temperature, and is explained by infrared, 13C nucleax magnetic resonance and ultraviolet spectra. A kinetic water loss equation of the consecutive first order depodation has been deduced and the highest temperature at which the sulfonated methyl phenolic resin (Ⅰ) will loss its efficiency is obtained.
