【摘要】 HGA-1聚合物由于具有特殊的分子结构 ,因此具有较好的酸液性质。该聚合物在不同的酸浓度、温度下 ,粘度下降幅度小 ,并且具有较好的时间稳定性。随着 Ca2 + 浓度的增加 ,体系粘度明显降低 ;具有较好的变粘酸性、抗温性、抗酸性 ,与其他酸液具有较好的配伍性 ,对油气藏不会造成二次损害更多还原

【Abstract】 Because of special molecular structures of polymer HGA 1,it has better performance in acid The polymer has less viscosity decline in different acid concentration and temperatures, with good stability of time With the increase of Ca +2 concentration,viscosity of the polymer system is declined obviously,which has good viscosifying acidity,temperature resistance and acid resistance It has good compatibility with the other acids,which would not cause a secondary damage to the reservoirs更多还原
