The invention provides a paraffin control device for a gas-condensate well and an exploitation tube column, and relates to the oil and gas exploitation technology. According to the paraffin control device for the gas-condensate well, a paraffin control tube body for being connected between a packer and a screen tube is arranged, a paraffin control agent is arranged in the paraffin control tube body, thus, in the exploitation process, condensate gas in a stratum enters the paraffin control tube body through the screen tube and makes contact with the paraffin control agent in the paraffin control tube body, a reaction is carried out, a paraffin precipitation point of condensate paraffin and a solidifying point of condensate oil are reduced, then a paraffin control effect is achieved, the blocking phenomenon in the exploitation process is reduced, and the yield of the gas-condensate well can be increased.
