Zusammenfassung:The invention relates to a self-adaptive degradable material suitable for underground reservoir temporary plugging fracturing operation. The material comprises a degradable flexible container and a degradable wire harness packaged in the degradable flexible container, wherein the degradable wire harness is provided with a knot which protrudes outwards relative to the wire harness. According to thematerial, the degradable flexible container is adopted to completely coat or wrap the degradable wire harness to form a composite structure similar to amber, the composite structure can be driven byunderground fluid to be conveyed to a target crack or hole to be treated, as the degradable flexible container is mainly made of a flexible degradable resin or the flexible degradable resin and a water-soluble resin, the degradable flexible container has good flexibility, and can generate self-adaptive deformation to a certain extent under the action of the underground fluid and formation pressureso as to generate deformat
