Abstract

Device for transmitting to the surface the measures effected at the bottom of a borehole during drilling is the form of pressure impulses applied to the drilling mud is obtained to the lower part of the drilling column, has at least one measuring instrument at the bottom, device for transforming the measurement into corresponding electrical signals, and a valve placed in the flow of the drilling mud for producing pressure impulses in the mud. The valve is fixed to the end of an axle on which are fixed a number of electromagnetic armatures separated by spaced in the interior of which the axle is surrounded by electrical coils associated with simultaneous electrical feelers for the coils. Assembly of armatures and coils is placed in a sealed chamber with an orifice for the passage of the axle provided with seal at its upper part.
