A segmented mining process pipe column for rapidly recovering productivity of a horizontal sand prevention failure well comprises a Y-type production pipe column arranged in a sleeve, a sand prevention packer installed at the bottom of the sleeve and a sand prevention screen pipe connected with the sand prevention packer, wherein a screen pipe type production sliding sleeve is installed at the lower end of the Y-type production pipe column, and a positioning sealing assembly is installed at the lower end of the screen pipe type production sliding sleeve, is in contact positioning with a suspension packer arranged at the lower end of the positioning sealing assembly through a positioning part and is in matched sealing with a built-in sealing drum of the suspension packer through a sealing assembly. The segmented mining process pipe column further comprises a plurality of groups of giving-up pipe columns formed by sequentially connecting well completion oil pipes among the suspension packer, a packer expanding when meeting water and oil and a screen pipe type bottom-hole regulator, and the plurality of groups of giving-up pipe columns are sequentially installed in the sand prevention screen pipe. A sand outlet well section is divided into a plurality of sections, and blockage of the sand outlet position is achieved; normal mining of other sections is kept, and modification of a horizontal section production cross section from production fluid one-way flow to branch flow is achieved.
