交联聚合物溶液流动特性及其评价方法

Flow Property and Its Evaluation Methods of Colloidal Dispersion Gel

依据大庆油田交联聚合物深度调剖技术矿场试验需求 ,通过井口取样和进行化学剂浓度检测分析 ,对矿场交联聚合物溶液配制工艺的合理性进行了评价。在此基础上 ,从阻力系数、残余阻力系数、传输能力和流动成胶等方面对交联聚合物溶液的流动特性进行了实验研究。实验结果表明 ,由于分子结构上的不同 。

According to the requirement of pilot test in in-dept blockage with colloidal dispersion gel (CDG) in Daqing oil field, chemical compositions of the CDG obtained from the injectors in pilot test area are analyzed by atomic absorption instrument. The availability of mixing equipment of CDG solution and its technological process has been proven by above-mentioned job. Taking this as basis, flow property for the CDG is researched by measuring a few of parameters such as resistance factor and residual resistance factor. The experimental results show that difference on flow property exists between CDG and polymer solution.
