| 摘 要： | 弱凝胶作为一种调驱剂已经被国内外各大油田广泛采用,弱凝胶技术成功地解决了油田注水开采中后期的高产水率问题,改善了注入水的波及效率,提高了原油的采收率。为了进一步研究弱凝胶的适用范围,研究了地层水中所含主要盐离子(如Na+ 、K+ 、Mg 2+和Ca 2+ )及总矿化度对弱凝胶成胶性能的影响,对比分析了其作用机理,并给出了弱凝胶的抗盐范围。

| Abstract: | Weak gel has been applied successfully in water flooding reservoirs to modify profile and to control mobility for a few years. Results of laboratory experiments and field trials have indicated that the injection of the weak gel could observably improve sweep efficiency and enhance oil recovery in water flooding reservoirs. The laboratory investigation was conducted todetermine the influence of metallic ions and total salinity on weal gel. The results have showed that the factors, including types and concentration of the metallic ions ( Na+ 、K+ 、Mg 2+ 、Ca 2+ )the total salinity, have important impacts on the properties of the weak gel. |
