Abstract

The adsorption of anionic surfactant of sodium dodecyl sulfate(SDS) onto preformed particle gel(PPG) and the effects of SDS on the swelling ratio of PPG were combined.The effects of anionic surfactant sodium dodecyl sulfate on the rheology of preformed particle gel were also studied by using steady shear and oscillatory shear rheological experiments.The interaction mechanism of SDS and the rheology of preformed particle gel was discussed.The results show that the adsorption of SDS increases and the swelling ratio of PPG first decreases and then keeps stable with the increase of SDS.The preformed particle gel exhibits shear-thinning property and its viscosity is significantly influenced by SDS at lower shear rate.With the increase of SDS concentration,the yield stress of the preformed particle gel decreases and the storage modulus first decreases and then increases.

预成型颗粒凝胶与十二烷基硫酸钠的相互作用

研究了阴离子表面活性剂十二烷基硫酸钠(SDS)在预成型颗粒凝胶(PPG)上的吸附作用以及SDS对PPG溶胀率的影响。通过稳态剪切和振荡剪切流变实验，研究了阴离子表面活性剂十二烷基硫酸钠对预成型颗粒凝胶流变学的影响。讨论了SDS与预成型颗粒凝胶流变学的相互作用机理。结果表明:随着SDS用量的增加，SDS的吸附量增加，PPG的溶胀率先减小后保持稳定;在较低剪切速率下，SDS对预成型颗粒凝胶的粘度有显著影响。随着SDS浓度的增加，预成型颗粒凝胶的屈服应力减小，存储模量先减小后增大。

期刊介绍： Journal of China University of Petroleum (Natural Science Edition) was founded in 1959. It is a comprehensive academic journal with distinct petroleum characteristics, supervised by the Ministry of Education, sponsored by China University of Petroleum (East China), and publicly issued at home and abroad. It focuses on publishing innovative achievements and high-level papers in the fields of geology and exploration engineering, geological energy extraction engineering, energy equipment and control engineering, energy chemistry and materials engineering. The journal is a Chinese core journal, a statistical source journal of Chinese scientific and technological papers, and a source journal of the Chinese Science Citation Database. It is fully included in many domestic databases such as the Chinese Science Citation Database (CSCD), China National Knowledge Infrastructure, Wanfang Data, Chongqing VIP, and China Petroleum Abstracts; and has entered the Engineering Index (EI), Scopus database, the American Chemical Abstracts (CA), the American Petroleum Abstracts (PA), the Russian Abstracts Journal (AJ), the American Cambridge Scientific Abstracts: Materials Information (CSA:MI), the Japanese Bulletin of Scientific and Technical Literature (CBST), the American Stephens Database (Eh), and the American Geological Reference and Preview Database (GRP).
