海上油田产出液中聚合物微球含量检测

Detection of polymer microspheres in offshore oilfield produced fluid

采用凯氏定氮法测定油田产出液中聚合物微球含量,通过绘制聚合物微球检测曲线,从而得到油田产出液中聚合物微球含量以及其变化规律。结果表明:该方法快速高效的检测出聚合物微球含量,平行测试的相对误差在5%以内,精确度和准确度较好,能够满足测试和使用要求。

Produced fluid of oilfield is determined by Kieldahl method.By drawing polymer microspheres monitoring curve,it shows that the content of polymer microspheres and dynamic change regularity.The experimental data reflect injection of polymer microspheres.The experimental results show that the method is rapid and efficient.Through parallel tests,the relative error is low.It is characterized by good precision and accuracy,simple operation.The experimental results can satisfy the requirements of operating company.
