ABSTRACT:
The invention relates to measuring the bubble point of oil down a well drilled into an underground formation. The pressure is measured by an apparatus lowered down the well. The apparatus comprises a chamber (2) in which a small quantity of oil is confined in a volume which is variable by a needle (3) having portions of different diameters (3a, 3b) capable of being inserted to a greater or lesser extent into the chamber (2) under drive from a motor (7). Values of pressure inside the chamber and of chamber volume are respectively measured by a manometer (11) and by a displacement sensor (12) connected to the needle (3) and are transmitted to the surface.
