The present invention relates to a fluid discharge device able to be positioned in a hydrocarbon production well. The device comprises a discharge tube, one end of said tube being able to be connected to a pump positioned in the hydrocarbon production well for pumping at least one liquid; an insulator in contact with the tube and able to limit a flow of fluid between a wall of the tube and a wall of the well, from a first space formed between the insulator and the well bottom toward a second space formed between the insulator and the well head; an opening formed on an opening side on said tube able to allow a gas to flow from said first space into said tube; and a non-return valve mounted on said opening, the valve being able to block a fluid present in said tube from flowing toward the first space. |
