摘要
采用单宁酸与2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和丙烯酸(AA)接枝共聚,合成了一种单宁酸接枝共聚物。对此共聚物在钻井泥浆中的降粘性能进行了室内初步评价,结果表明,AMPS/AA/单宁酸接枝共聚物用作钻井泥浆降粘剂,具有较好的耐温抗盐能力。
The AMPS/AA/tannin acid graft copolymer as drilling mud viscosity - reducing agent was synthesized from tannic acid, acrylic acid, and 2 - acrylamido - 2 - methylpropanesulfonic acid. The mud performances of the AMPS/AA/tannin acid graft copolymer was evaluated in laboratory. The experimental results showed that the copolymer as drilling mud viscosity - reducing agent has very good heat resistance and salt tolerance.
