Abstract
An articulated jet pump is provided usable more particularly in TFL techniques for activating hydrocarbon or water-producing wells. The pump of the invention may be positioned in production tubing by travelling through this tubing as far as the chosen position and comprises a nozzle adapted for being fed with drive fluid, the nozzle having an outlet orifice which cooperates with a mixer-diffuser assembly placed in an extension of the nozzle. The pump is formed from at least two elements articulated together at the level of the mixer.
