The invention relates to a petroleum extraction device, and particularly relates to a gravel-prepacked sand control pipe specially used for petroleum extraction, which comprises a base pipe and a sand control pipe shell sheathed outside the base pipe; a gravel layer is filled between the base pipe and the sand control pipe shell, and a plurality of deflector holes are arranged on the pipe wall of the base pipe and the pipe wall of the sand control pipe shell. Due to the existence of the gravel layer in the pebble prepacked sand control pipe, the extraction device has good sand controlling effect. A vertical shell can change the flow form and direction of the fluid, thus preventing the blockage of the shell. The base pipe with high flow conductivity can ensure that all the fine sand passing through the gravel layer can output through the base pipe without generating the blockage of the base pipe.
