目前部分油田已开始进行聚合物驱油,而聚合物浓度是一项重要指标,准确测定聚合物浓度对保证聚驱效果有重要的作用。目前油田上检测聚合物浓度的方法主要为浊度法和淀粉——碘化镉法,但每种方法均受到较多因素的影响,使测定结果存在较大的偏差。本文将详细对聚合物浓度检测方法和影响因素进行分析,使测定结果更加准确。 At present, some oilfields have started polymer flooding, and polymer concentration is an important index. Accurate determination of polymer concentration plays an important role in ensuring the polymer flooding effect. At present, the methods for detecting polymer concentration in oilfield are mainly turbidimetric method and starch-cadmium iodide method, but each method is affected by many factors, which leads to large deviation of the determination results. This article will detail the polymer concentration detection methods and influencing factors for analysis, the determination of the results more accurate.
