| 摘 要： | 结合孤东油田聚合驱的实际情况,探讨了温度、矿化度、pH值、搅拌速度、搅拌时间及配制参数等因 素对聚合物溶液粘度的影响程度。pH值控制在7~9、温度在10~18℃、搅拌速度在80 r／min以下时,配 制的聚合物溶液具有较高的粘度;Na+含量低于200 mg·L-1、Ca2+和Mg2+的含量低于100 mg·L-1、 Fe3+的含量小于20 mg·L-1时,有利于提高聚合物溶液粘度的保留率;溶解氧对HPAM溶液的粘度影响 较大。

| Abstract: | This paper studies the influences of temperature, salinity, pH, stirring rate, stirring time and manufacturing parameters on viscosity of polymer solution according to the status of polymer flooding in Gudong oilfield. Polymer solutions made up at a pH between 7 and 9, a temperature between 10 and 1℃, and a stirring rate under 80 r/min have relatively high viscosity. When the content of Nal + is below 200mg · L-1, content of Ca2+ and Mg2+ below 100 mg · L-1 and content of Fe3+ below 20 mg · L-1, retention rate of viscosity of polymer solution can be easily improved Dissolution oxygen has relatively large influences on viscosity of HPAM solution. |
