Provided is a modified ceramsite sand filter pipe. The modified ceramsite sand filter pipe comprises an upper connector (1), a spring seat (2), a spring (3), a screen pipe (4), a modified ceramsite filter cylinder (5) and a central pipe (6). The modified ceramsite sand filter pipe is characterized in that the modified ceramsite sand filter pipe is of a cylindrical structure, the upper connector (1) with internal threads is arranged at the upper end of the central pipe (6), external threads are arranged at the lower end of the central pipe (6), the spring seat (2) is arranged on the upper portion of the central pipe (6), the spring (3) and the modified ceramsite filter cylinder (5) are arranged on the lower portion of the central pipe (6) in a sleeved mode in sequence, and the stainless steel screen pipe (4) is arranged outside the modified ceramsite filter cylinder (5). The modified ceramsite sand filter pipe is novel in design, simple in structure, resistant to high temperature, high in strength and capable of resisting muddy blocking, solves the problem that multi-hole filtering media of an existing metal sand filter pipe are poor in high-temperature stability, achieves direct downward filtering production after steam injection, simplifies sand prevention operation of a thermal production well, reduces the cycling time, improves the success rate of sand prevention, prolongs the sand control life, reduces pollution of oil layers, and improves the effect of thickened oil thermal recovery development.
