  • Self-growing dispersed particle gel active mobility control system and fluid channeling control method for low-permeability-tight reservoir
    Patent number: 12024975
    Abstract: The invention relates to the field of oilfield development engineering, and discloses a self-growing gel dispersion active fluidity control system and a fluid channeling control method for a low-permeability-tight reservoir. The system contains 100 parts by weight of a self-growing gel dispersion and 0.15-0.6 part by weight of a surfactant, the self-growing gel dispersion is prepared by shearing and grinding nano-reinforced chromium-aldehyde double-group cross-linked integral gel, and the preparation method of the nano-reinforced chromium-aldehyde double-group cross-linked integral gel comprises the following steps: adding a functional polymer, a phenolic resin cross-linking agent, are organic chromium cross-linking agent and a nano-reinforcer into water, mixing, and curing.
