定氮法检测凝胶采出液中聚合物浓度的研究
Research on the polymer concentration in the gel produced liquid detected by fixed nitrogen method
摘要
Abstract
In order to accurately determine the polymer concentration in the produced liquid of gel profile control and flooding wells, the standard curves of polymer solution and polymer gel are drawn by using the method of fixed nitrogen.The standard curve is optimized by the physical simulation results of the polymer concentration in the produced liquid.Sixteen production wells in the gel test area of Daqing Oilfield are extracted randomly, and the fixed nitrogen and starch cadmium iodide method are used to detect the polymer concentration in the produced liquid.The error of test results is analyzed and the corresponding empirical formula is fitted.The research results show that the method is accurate and effective for the detection of polymer concentration in the gel produced liquid.关键词
