摘要
以聚合物HTP和活性碱NPS复配,制得碱/聚合物复合驱体系,考察了溶解氧、金属离子、H2S、剪切作用和温度对碱/聚合物复合驱体系粘度的影响。结果表明,空气中氧含量足以导致复合驱体系丧失流度控制能力;金属离子对其体系粘度具有很大影响;H2S对体系粘度伤害严重,但H2S吸收剂AS几乎可完全消除其影响;复合驱体系对剪切作用敏感;温度升高,复合驱体系粘度下降。本研究可为增强碱/聚合物复合驱体系的粘度稳定性提供依据。
A alkali/polymer（AP） flooding system was compounded by polymer HTP and active alkali NPS. The affecting factors on the viscosity stability of the flooding system were studied. The results showed that dissolved oxygen, metallic ion, H2S, shearing action and temperature affected the AP system viscosity obviously. This study provided the evidence for improving the viscosity stability of the AP flooding system.
