摘　　要：研究了非离子表面活性剂Triton X-100在调堵剂预交联凝胶颗粒(PPG)上的吸附和脱附特性,其吸附等温线符合Langmuir型吸附,吸附在颗粒上的表面活性剂能够被后续注入水逐渐洗脱下来,仍然可以提高原油采收率。利用激光粒度仪研究了Triton X-100对PPG膨胀性的影响规律,发现吸附后PPG的粒径减小。稳态和动态流变性实验研究表明,随着Triton X-100浓度的增加,溶胀后的PPG逐渐表现出假塑性流体特征,储能模量逐渐降低,PPG的注入性和运移性得到提高。The adsorption of nonionic surfactant Triton is indicated that the adsorption isotherms of Triton X-100 X-100 onto preformed particle gel （PPG） was studied. It onto PPG can well be fitted by Langmuir model which is used to describe the monolayer molecule adsorption. The effect of Triton X-100 on the swelling ratio of PPG was discussed using laser size meter and it is found that the size of PPG decreases in the presence of Triton X-100. The steady and dynamic rheological experiments results show that PPG exhibits shear-thinning property and is easily broken under shearing in the presence of Triton X-100. With increase of Triton X-100 concentration, the storage modulus of PPG decreases.
