| Abstract: | Humic acid reacted with modifying agent to enhance its dispersibility and solubility in oil. Some influencing factors on product were taken into account through the multiple sets of single factor experiments,such as the kinds of modifying agent, reaction ratio, reaction temperature and reaction time. The best reaction condition was determined as follows：quality ratio of humic acid and modifying agent 11：4,reaction temperature 180℃and reaction time 8 h. The infrared spectrogram has confirmed the success of modified reaction. The modified humic acid fluid loss reducer possesses good fluid loss property with 13 mL HTHP loss at 3% dosage at 150 ℃, comprehensive performance is superior to the asphalt fluid loss agent. |
