海上油田聚表二元复合体系组成快速检测技术
Fast detection technology of composition of polymer/surfactant compound flooding in offshore oilfield
摘要
Abstract
The traditional method for detecting starch-cadmium iodide concentration can not detect the concentration of surfactant in the solution of two-element compound,concentration of polymer containing only,but the method can not meet the site requirements in the timeliness and accuracy. The technology innovatively uses COD-fixed nitrogen combined approach,first completely oxidizing reducing substances(polymer and surfactant,etc.)in sample to obtain total COD in the solution through the chemical oxidation method,then determining the concentration of polymer in the system of polymer/surfactant compound driven by the nitrogen-fixing method.Through mathematical means to quantify each equivalent and environmental influencing factors,and deducting the background value,the component content of polymer/surfactant two-element system can be calculated by establishing the function correlation between the produced liquid component content and COD value. The technology has successfully applied in offshore platform,realizing for the first time poly table binary combination flooding oil system group concentration measured directly on the platform and the injection end of fluid quality and produced fluid end group concentration can be effectively controlled. It is of great significance for the guidance of offshore oilfield binary combination flooding dynamic tracking adjustment and produced fluid treatment.关键词
