抗盐型交联聚合物溶液的合成条件研究

STUDY ON SYNTHESIS CONDITIONS FOR SALT-TOLER-ANT CROSS LINKED POLYMER SOLUTION

采用相对分子质量高的AM/AMPS二元共聚物和交联剂柠檬酸铝 ,开展了以改善聚合物驱为目的的交联聚合物溶液 (LPS)体系研究 ,考察了影响抗盐型LPS的形成及其性能的多种因素。研究结果表明 :该体系在矿化度为 10 0 0 0 0mg/l的模拟地层水中仍具有很强的成胶能力 ,表现出优异的抗盐性能 ,拓展了LPS的应用范围 ,显示出良好的应用前景。

In this article,the high molecular weight AM/AMPS copolymer and crosslinker AlCit are adoptde to investgate the system of Linked Polymer Solution for flooding application.The influences of various factors on formation and performance of Linked Polymer Solution are investgated.The results indicate that gelling ability of Linked Polymer Solution is excellent at high salinity of 100 000mg/L,there-fore it offers the possibility to extend the use of Linked Poly-mer Solution in flooding application.
