油田污水中有机物对复合体系界面张力的影响

Study on the Effect of Organism Existing in the Oilfield Water on the Interfacial Tension of ASP System

影响复合体系界面张力的因素很复杂 ,如表面活性剂的性能、油的性质以及油与表面活性剂的配伍性等。同时 ,水质也是影响体系界面张力的主要因素之一。通过系统的室内研究 ,对比分析了大庆油田不同区块污水中有机物含量及其分布特征 ,较为详细地研究了污水中有机物对复合体系界面张力的影响规律 ,确定了影响体系界面张力的主要有机物类型及其含量。

The effecting factors on the interfacial tension of ASP system are complex,water quality is also important one besides surfactant performance,oil property and the matching between surfactant and oil.By systemic experiment,this paper analyzes the content and distribution character about the organism in different block's sewage,investigates it's effecting rules to the IFT,confirms the main organism's type and concentration.
