| 摘 要： | 采用木质素磺酸钙与2－丙烯酰胺基－2－甲基丙磺酸（AMPS），丙烯酸（AA）和二甲基二烯丙基氯化铵（DMDAAC）接枝共聚，合成AMPS／AA／DMDAAC－木质素磺酸盐接枝共聚物，将其作为钻井液降粘剂，并对其在钻井液中的降粘性能进行了室内初步评价。结果表明，AMPS／AA／DMDAAC－木质素磺酸盐接枝共聚物用作钻井液降粘剂，具有较好的抑制性和耐温抗盐能力。

| Abstract: | The AMPS/AA/DMDAAC - lignosulphonates graft copolymer as viscosity reducer for drilling fluids was synthesized from calcium lignosulphonates, acrylic acid, 2 - acrylamido - 2 - methylpropanesulfonic acid and diallyl dimethyl ammonium chloride. The mud properties of the AMPS/AA/DMDAAC - lignosulphonates graft copolymer was evaluated in laboratory. The experimental results showed that the AMPS/AA/DMDAAC - lignosulphonates graft copolymer has very good heat resistance, salt tolerance and inhibiting action when it is used as viscosity reducer for drilling fluids. |
