A process and device making possible the guidance of the drilling tool through geological formations including an analytical device for directional geological analysis that carries out measurements as the drilling advances for guiding the drilling tool through the geological formation. The drilling column at its lower end includes the drilling tool (1) driven by a turbine (2) mounted on an elbow (4), a directional analytical device (3) that carries out measurements according to well set directions, a logging sensor (5), a drilling sensor (6) and a topographic probe (7). When drilling through specific geological formations, the information provided by the directional analytical device (3) is used for guiding the drilling tool in real time.
