Abstract

1. Method for measuring the resistivity of fluids in a borehole by means of a sonde body adapted to be moved in the borehole and having a first pair of annular electrodes (34, 37) which are supported on its lateral surface on each side of a second pair of annular electrodes (35, 36), comprising the steps of passing an electrical current (i) around said sonde body through the fluids in the borehole between the electrodes of one of said pairs, and detecting a potential difference (u) through the fluids of the borehole between the electrodes of the other one of said pairs, characterized by maintaining said electrodes (34, 35, 36, 37) at a lateral distance (d) from the borehole wall which is at least equal to the longitudinal spacing (b) between the electrodes (34, 37) of said first pair to derive a signal representative of the resistivity of the borehole fluids whatever is the position of the body in the borehole.
