Abstract
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.
