| 摘 要： | 本文介绍了一种新的用于地层酸化的复合缓速体系。该体系由PAM、SAS和ZrOCl_2复配而成,最佳复配浓度分别为0.80％、0.20％、0.05％。试验证明,比相同条件下的PAM或SAS有更好的缓速效果。文中分析了复合缓速体系的作用因素及交联剂ZrOCl_2对PAM的交联作用机理。研究结果表明,温度、电解质浓度及PAM分子量对缓速效果都有影响。温度越高,缓速倍数越大;电解质浓度越大,缓速效果越差;PAM分子量越大,缓速效果越好。在复合缓速体系中加入交联剂ZrOCl_2后,缓速效果更好。

| Abstract: | A new complex retarded system used in acidification which contains PAM, SAS and ZrOCl2 has been developed. Its retarded effect is better than that of PAM or SAS respectively on the same conditions. The influence factors of complex retarded system and the role of ZrOCl2 in the system have also been discussed. The results of research show that the temperature, the concentration of electrolytes and molecular weight of PAM can affect the retardation and the retardation will become better -while ZrOCl2 is mixed with the system. |
