ABSTRACT:
A system for providing measurements while drilling a well in which a drill string, made up of standard lengths of drill pipes, some of which may be drill collars, extends from the earth's surface in a borehole, drilling fluid being circulated in the drill string and borehole, the measurements being transmitted to the earth by a pulser which produces, in response to electrical signals from a measuring instrument, pressure pulses in the drilling fluid which are detected and decoded at the earth's surface, the pulser being mounted in a special pulser sub which is of short length and enlarged internal diameter compared to a standard drill pipe and which is threadably secured at each end in the drill string, and an elongated housing supported by the pulser sub, the housing having an outside diameter less than the internal diameter of the drill pipe and being slidably received in drill pipe adjacent the special sub, the elongated housing containing instrumentation or batteries, or both which are connected to the pulser.
