Abstract

See full text

A measuring while drilling apparatus for use in the drilling of subterranean wells comprises a plurality of interconnected tubular housings which are insertable into and removable from a drill string by a wire line. A hollow plunger on the bottom of the apparatus is vertically shiftable with respect to a fixed diameter orifice disposed in the path of the drilling fluid flow. Fluid pressure forces derived from the drilling fluid effect the movement of the plunger forward and away from the orifice to create pressure pulses which are transmittable through the drilling fluid to the surface. Sensors provided in the housings generate signals, which are converted by a downhole controller, to effect the sequential generation of the positive pressure pulses to be indicated at the surface of the well by a digital readout of the outputs of the various sensors carried in the tubular housings.
