Abstract

A logging-while-drilling tool for incorporation in a well drill string includes a valve adapted to produce in the column of drilling fluid a pressure wave with characteristics representative of a sensed downhole condition, e.g. the wt. on the bit, the valve including a rotor provided with turbine blades and located downstream of a drilling fluid conditioning unit including a jet nozzle located upstream of an element arranged to impart angular motion to at least a part of the drilling fluid passing from the jet nozzle to the valve rotor. The conditioning unit can ensure that the hydraulic torque developed by the valve rotor is constant regardless of variations in the flow rate and/or density of the drilling fluid.
