The invention discloses a degradable material suitable for low-temperature wells, a preparation method and application thereof. The raw material components of the degradable material include: a matrix resin containing glycolic acid homopolymer and/or glycolic acid copolymer; and a water-absorbent resin. During the preparation, the base resin and the water-absorbing resin are melted, blended and extruded; in terms of application, the degradable material is processed into components for downhole tools, which are used in the exploitation operations of oil and gas fields. |
