Title:
NANO ACTIVE AGENT SYSTEM, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/047904
Kind Code:
A1
Abstract:
Disclosed in the present application are a nano active agent system, and a preparation method therefor and an application thereof. The nano active agent system comprises a cationic surfactant, a non-ionic surfactant, an amphoteric surfactant, modified graphene oxide, and a solvent. Compared with common surfactants, the nano active agent system provided by the present application has a better oil displacement effect; adding the surfactant during preparation makes the system be more stably dispersed under a high-salt condition, and the nano active agent system has ultra-low oil-water interfacial tension, and the viscosity reduction rate of the nano active agent system on thickened oil can reach 90% or above; and compared with common surfactant viscosity reducers, the nano active agent system has a better oil displacement effect.
