Abstract | Disclosed is a carbon-dioxide-responsive self-thickening intelligent fluid based on supramolecular self-assembly. The carbon-dioxide-responsive self-thickening intelligent fluid comprises a Gemini surfactant, a single-chain amide molecule having a tertiary amine head group and water, wherein the Gemini surfactant and the single-chain amide molecule having a tertiary amine head group are self-assembled to form a vesicle structure dispersed in water, with a hydrophilic head group being located outside and a hydrophobic tail group located inside. The method for preparing the carbon-dioxide-responsive self-thickening intelligent fluid of the present invention is simple, the injection viscosity is low, and the fluid is converted into a gel when encountering carbon dioxide, so that the viscosity is greatly increased, thereby effectively solving the problems that when a carbon dioxide gas drive is used to enhance recovery in a low-permeability oil reservoir, channeling flow of the gas occurs along local hypertonic channels, and of a substantially reduced swept volume caused thereby, etc. |
