Abstract
This invention relates to a system for pumping an effluent that is produced by a geological formation, in which a rotary pump (3) is installed and driven in rotation by a continuous tube (12) that rises up to the surface. The tube makes it possible to inject a fluid, for example, a liquefier or a lubricant. This invention also relates to a pumping method in which rotor (24) of the pump is installed with a continuous tube (12), of the 'coil tubing' type.
