The invention provides a self-degradable high-strength filling pipe. The self-degradable high-strength filling pipe comprises a kerf center pipe and a polymer pipe, wherein the kerf center pipe is tightly sleeved with the polymer pipe, and at least three flow-guiding grooves which are communicated in the axial direction are evenly formed in the outer wall of the polymer pipe. A longitudinal rib on the outer wall of the kerf center pipe is formed between every two flow-guiding grooves. Couplings are connected to the two ends of the kerf center pipe respectively and arranged on the kerf center pipe through snap rings. The kerf center pipe, the polymer pipe and the couplings are all made of polylactic high-polymer materials. A self-degradable soluble filling screen pipe is adopted, and therefore the problems that in the sleeve breaking process, the sleeve bending process and the sand prevention construction process of a complex structural well, drilling and plugging are difficult, and the success rate in operation of lifting and dropping a sand prevention pipe is low are solved; moreover, due to annular space formed by the screen pipe, the open area of fluid is enlarged, grinding resistance loss during flowing of the fluid is reduced, and the fluid production capacity of an oil well is increased.
