A CO-sensitive fracturing and displacement fluid contains a surfactant, an auxiliary agent, water, and CO, wherein COis liquid and/or supercritical CO. The CO-sensitive fracturing and displacement fluid provided by the invention does not flow back after completion of fracturing construction, and the gel breaking fluid displacement is carried out after soak for a period of time to improve the tight oil recovery ratio. The CO-sensitive fracturing and displacement fluid exerts the 'one-agent multi-purpose' function of sand carrying, COenergization and oil displacement, surfactant imbibition and oil discharge of a fracturing-displacement system in different development and production stages, and achieves the dual goals of expanding the utilization degree of tight oil and improving the displacement efficiency of the tight oil, which can effectively reduce costs and achieve the goal of unified, highly efficient and green development of oil and gas fields.

The flow modifier particle composition contain a viscoelastic base agent, a selective solubilizer, a density modifier, a sweller, and an optional plasticizer, wherein based on the total weight of the flow modifier particle composition, the content of the viscoelastic base agent is 30-90 wt %, the content of the selective solubilizer is 3-30 wt %, the content of the density modifier is 0.1-30 wt %, the content of the sweller is 1-30%, and the content of the plasticizer is 0-10 wt %. The present invention further discloses a flow modifier, which contains the flow modifier particle composition and a carrying fluid that contains water and a surfactant. The present invention further discloses a preparation method of the flow modifier, and a use of the flow modifier and the flow modifier particle composition in exploitation of fracture-cave reservoirs.
