摘　　要：聚驱过程中存在聚合物黏度过高的问题而影响了原油采收率,因此提出降低聚合物黏度的问题。木质素作为一种廉价的表面活性剂用于三次采油,在油田有广泛的应用前景。对于同浓度同体积的HPAM,加入木质素的质量越多,黏度下降速度越快。木质素与多种降黏剂的复配降黏效果实验中,降黏效果的比较为:HCl>NaS2O8>NaClO。The existing problem that the viscosity of polymer is too high that affects the oil recovery efficiency, so it is posed a issue to reduce the viscosity of polymer, lignin is used in tertiary oil recovery as a cheap surface active agent. It has a extensive expecting of used in oil field. The viscosity of HPAM of same concentration and same volume is reduce faster when mixed with more lignin. The conclusion of HPAM viscosity reduction experiment show that effect is HCl〉NaS2O8〉NaClO.
