摘要: Disclosed is a carbon-dioxide-responsive self-thickening intelligent fluid based on supramolecular self-assembly, which 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 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.

摘要: The embodiments of the present application disclose a method and an apparatus for determining flow rates of components of multiphase fluid. The method comprises: performing a first magnetization treatment and a second magnetization treatment on multiphase fluid in a pipeline in a target oil and gas well, respectively, to obtain first magnetized multiphase fluid and second magnetized multiphase fluid; determining a first echo train signal set and a second echo train signal set corresponding to the first magnetized multiphase fluid and the second magnetized multiphase fluid, respectively; determining contents of an oil phase component, a water phase component, and a gas phase component of the multiphase fluid at a specified horizon position, and determining a flow velocity of the multiphase fluid at the specified horizon position; and determining flow rates of the oil phase component, the water phase component and the gas phase component in the multiphase fluid. The technical solutions provided by the embodiments of the present application can improve the accuracy of the determined flow rate of each component of the multiphase fluid.

摘要: A permeability-enhancing flooding system for tight oil reservoirs and preparation and use thereof are disclosed. The permeability-enhancing flooding system is present in a state of oil-in-water droplet and composed of a surfactant, an oil-soluble substance and water, and has an outer phase that is an aqueous solution containing the surfactant, and an inner phase that is the oil-soluble substance; and the surfactant comprises one of nonionic gemini surfactants and anionic gemini surfactants, or a combination of two or more thereof. The preparation process for the permeability-enhancing flooding system is simple to operate, suitable for industrialized production, and low in overall cost, and has obvious application prospects in the field of tight oil reservoirs for an enhanced oil recovery.
