Abstract
A tool-positioning device is composed of a branch assembly in which each branch tube communicates with each branch flow string, an intermediate assembly provided with convergent tubes and a connecting assembly provided with a spline for guiding the connecting assembly with respect to one of the flow strings. An orientation and guiding member is interposed between the intermediate assembly and pumping means housed within a production tube. The orientation and guiding member has a slit which is oriented with respect to the spline in order to have a fixed and invariable position.
