A wall body structure for fluid injection well comprising a porous media with multiple pores as a wall body capable of increasing area of contact with soil and preventing efficiency reduction caused by closing of the pores is provided to efficiently suck a fluid such as underground water or gas within soil or smoothly inject chemicals for decomposing contaminants into the soil. In a wall body structure for a fluid extraction well and a fluid injection well used in a process of in-situ remediation of a contaminated underground space, a method for manufacturing the fluid extraction well comprises the steps of: (a) preparing cylindrical porous media with different pore sizes as materials for wall bodies; (b) preparing a porous media with large pore size as an outer wall body(21) of the fluid extraction well; (c) preparing a porous media with small pore size as an inner wall body(23) of the fluid extraction well; and (d) constructing the fluid extraction well by closing top and bottom covers(25,26) on top and bottom of the wall body; and (e) installing the fluid extraction well at a contaminated soil area.
