模糊综合评判在聚合物优选中的应用

Application of fuzzy comprehensive judgment in optimum choice of polymer solution

依据聚合物驱提高采收率原理和室内实验方法,分析了评价聚合物溶液黏度性质的单因素指标,并用模糊综合评判方法,评价了不同品质聚合物溶液扩大波及体积能力.结果表明:利用模糊综合评判方法,可以实现对多因素影响下不同品质聚合物溶液性质优劣的定量评价;指出在中相对分子质量、超高相对分子质量和抗盐聚丙烯酰胺3种聚合物溶液中,抗盐聚合物溶液黏度性能最优.

The author analyzes the signal factor indicators that evaluate the viscosity property of polymer solution depending on the principle that enhanced oil recovery by making use of polymer flooding and indoor experiment methods,and the method of fuzzy comprehensive judgment has been introduced,which can be used to evaluate the ability of expanding the sweep volume of polymer solution with different qualities.The results show,we can realize the fix quantify evaluations on the property of different character polymer solution under the influence of many factors making use of the methods of fuzzy comprehensive judgment.In these three kinds of polymer solutions of the middle molecule polycrylamine solution,the macromolecule polycrylamine solution and the salt-resisting polycrylamine solution,the viscosity property of the salt-resisting polycrylamine solution is the best.
