  • EP 0 102 672 B1 has disclosed a measuring device for connection to a drill column for deep wells, having an electrically operated measuring unit for measuring relevant data, the measuring device being designed for supplying electrical energy via the drill column.
  • the measuring device converts soil properties into electrical signals and is driven into the soil for soil investigations. Owing to the arrangement of the measuring device provided at the end of the drill column, with the known measuring device only measured data can be recorded which relate to the soil region surrounding the measuring head at the end of the drill column. It is not possible with the known measuring device to record measured data above the bottom of the borehole.
  • One object of the present invention is to develop a measuring device according to the precharacterizing clause of Claim 1 .
  • the measuring device can be provided at any desired point in the drill string.
  • the measuring device can be arranged directly adjacent to the bit unit, with the result that measured values can be taken from the bottom of the borehole.
  • the arrangement of a plurality of measuring devices in one drill string is also easily possible.
  • the measuring device is supplied with electrical energy via the drill column.
  • the data transfer or signal transfer takes place from the measuring device to the surface.
  • an evaluation device is provided at the surface, the measuring device being electrically coupled to the evaluation device.
  • the electrical coupling is used firstly for the data transfer or signal transfer from the measuring device to the surface and can secondly also be used for the transfer of control commands.
  • the measuring device has a stable outer housing for accommodating and thus protecting the individual functional units.
  • the housing has screw connections at both of its ends.
  • the screw connections should preferably have an internal thread such that the housing corresponds to a bush from a connection point of view.
  • the functional units of the measuring device may have an associated transformer, in particular a voltage transformer, which converts the measured signals recorded by the measuring unit such that the converted signals, which may have a different frequency from the electrical energy supplied, are correctly identified by the evaluation device.
  • the evaluation device may also be designed such that the measured signals are derived from the energy consumption of the measuring unit.
  • the measuring unit can have a plurality of measuring instruments for the purpose of recording various data.
  • the individual measuring instruments may be of modular design, with the result that, if necessary, one type of measuring instrument can be replaced by another type of measuring instrument if the measuring device is used for a different application.
  • the sensors of the measuring unit In principle it is possible for the sensors of the measuring unit to be provided on the outside on the housing, with the result that the measured values are taken from the medium which flows past the housing on the outside.
  • a possible solution is to provide the sensors in a flow path within the housing.
  • at least one electrically operated pump is provided which is connected in terms of flow to the measuring unit.
  • an electrically operated two-way valve adjacent to the measuring unit in order to divert the medium under investigation, if necessary, either into the annular space or else into the drill column.
  • a possible solution is to provide at least one filter and/or valves.
  • a filter connected upstream makes it possible to largely prevent the pump and/or the sensors from being adversely affected.
  • the measuring device has an electrically, in particular electrohydraulically, operated packer.
  • the packer is provided for the purpose of dividing the annular space into a section above the packer and a section beneath the packer. In this case, the two sections are virtually sealed off.
  • the packer does not protrude beyond the housing or only protrudes beyond the housing to an insignificant extent.

  • the layer of lubricant in this case acts firstly as a protective layer and secondly as a sliding layer, which favours reinsertion of the packer into the housing.
  • the invention provides for the pump to be designed to lower the level of the annular space beneath the packer in the withdrawn state of the packer.
  • the inflow opening of the housing into the measuring device is in this case provided beneath the packer, while the outflow opening in the housing is located above the packer.
  • control unit for the purpose of driving the functional units, as necessary.
  • the control unit if necessary, is driven at the surface via the evaluation device, in which the measured values are displayed, evaluated and processed.
  • a generator which is provided at the surface is generally used for supplying energy to the measuring device.
  • the measuring device In order to ensure operation of the measuring device even in the event of operational faults of the generator, the measuring device has an energy store for an emergency power supply. Finally, this energy store is a rechargeable battery provided in the housing.
