摘要：
The thermal stability of zwitterionic wormlike micelle(Z-WLM) solution with different nanocelluloses(NCs) was investigated. The effects of NCs concentration on the dynamic viscoelastic behavior, thixotropy and creep of Z-WLM were studied by linear rheological methods. The experimental result shows that a wormlike micelle(WLM) structure is formed by 4wt% erucy lamidopropyl betaine surfactant solution with many unique rheological properties, including shear thinning behavior, viscoelastic behavior, creep behavior and higher thixotropy recovery behavior, et al. Compared to other NCs, the NCs with high -COOH mass fraction and large aspect ratio possess better thickening efficiency. Moreover, the NCs can increase the Z-WLM solution's relaxation time and storage modulus, extend its thixotropy recovery time of shear viscosity and dynamic modulus, improve its creep recovery performance and thermal stability, which can use as a stimulation fluid in high temperature reservoirs from 70℃ to 100℃. With the increase of NCs concentration, the viscoelasticity and creep recovery performance of composite systems are increased and its thixotropy recovery performance is decreased. © 2019, Editorial Office of Acta Materiae Compositae Sinica.
