ABSTRACT:
A device for the remote control of data out of a drill hole to the earth surface during the operation of a drilling device which comprises a drill bit, a drill string and a pump raising a flushing liquid into the surrounding annular space of the drill hole and downward into flow channels of the drill string, consisting of devices arranged in the drill string for the ascertaining of desired informational data for the conversion of the informational data into a series of electrical control signals for the producing of pressure pulses in the downward directed flow of the flushing liquid as a function of the control signals and for the production of the necessary electrical energy, characterized in such a way that the devices part of a coaxial support within the flow channels of the drill string form a structural unit and are arranged over each other; separated axial sections of the structural unit are grouped and that at least the topmost section of the structural unit is constructed as an independent component and by means of an energizable pick-up tool is detachable from the rest of the structural units from the earth surface and is capable of being pulled up through the flow channel of the drill string to the earth's surface.
