摘要
通过对深部调驱现场出现的问题进行分析,认为水质是影响凝胶成胶强度的一个关键因素。通过开展水质中钙镁离子、硫离子、悬浮物、含油量,pH对凝胶强度影响的单因素实验,并与模拟水进行了对比,发现硫离子和悬浮物会对凝胶强度造成很大影响,钙镁离子、pH值也会对凝胶强度造成一定程度的影响;而含油量对凝胶强度影响不大。
Water quality has great impact on polyacrylamide gel agent by analyzed problem of deep profile control experiment.The following factors of water quality：the pH value,the calcium ion,the magnesium ion,the sulfur ion,the suspended material,oil content and the concentration of various ions are analyzed,and conducted an experiment about their effects on the intension of polyacrylamide gel.The results indicated that：the sulfur ion and suspended material has huge damage on the hardness of gel ; the pH value,calcium ion and magnesium ion has medium impact on the hardness of gel,the content of oil has negligible effect.
