Definitions

  • the invention relates to a measurement method for cable core bores, in which a core inner tube with an independently functioning measuring probe attached is flushed into a core drill rod and locked in a core outer tube with a core bit via a core tube coupling, measured values are recorded and temporarily stored by the measuring probe and after the core inner tube is pulled out of the measuring probe be read out and an apparatus for performing the measurement method according to claim 1, wherein a tubular self-sufficient measuring probe, which contains a sensor part, a power supply, an electronic part and a data memory, is detachably connected to a core inner tube, which can be anchored in a core outer tube and which after Measurement for recovery can be connected to a core tube catcher which is attached to a core rope.
  • Such a measuring method and such a device are known from EP-A-0 338 367. They are used to collect data from the borehole during drilling to increase the efficiency of the core drilling process.
  • a disadvantage of this device is that the measuring probe is arranged in the core inner tube and without access to the free borehole cross section. This means that measurements in the open borehole are not possible.
  • the measuring probe consists of a drill collar, mechanically and electrically connected to the cable lug, to which a coupling rod is connected, to which the measuring tools are connected.
  • the probe furthermore comprises a coupling housing for connection to the drill pipe and a protective housing for the measuring tools, which has a measuring opening.
  • the invention is based on the general object to propose a suitable measuring method for cable core bores and a suitable device, in which the disadvantages of the prior art are avoided and in which one can work with an interchangeable measuring probe without having to remove the drill pipe and the special one Task to be able to carry out the measurement in free cross-section in front of the drill bit.
  • the invention is also based on the object of proposing a device for carrying out the method according to the invention.
  • the measurement method according to the invention for cable core bores and the associated device are ideally suited for the geophysical measurement of strongly deflected bores.
  • This new measurement concept which is based on self-sufficient measuring probes, which are flushed into the rod with the usual core tube and whose sensors look out of the front of the drill bit, the removal of the drill rod before the measurement is avoided, so that the work and time required for the Surveying work can be reduced significantly.
  • No cable connection is required during the measurement process itself, so that no complex side entrances to the linkage are required. Since the measuring probes are housed within the rod, there are no measuring probe losses.
  • the change in depth is preferably recorded simultaneously via a rod path recorder and stored in a correlated manner over time.
  • the probe is recovered from the core tube and read out.
  • the time and devil data information are assigned to the measurement data and a depth data file is created therefrom, which can be plotted on the spot on a printer.
  • FIG. 1 shows the principle of the measurement method according to the invention for cable core bores and a core outer tube 4 which is suitable for carrying out the method and is equipped with a core bit 2 and has a core inner tube 3 which is connected to a measuring probe 24 and can be connected to a core tube catcher 7 for recovery.
  • the core outer tube 4 is connected to a core drill pipe 6, which is located in a borehole 26 with a deflected part 27.
  • the core inner tube 3 accommodated in the core outer tube 4 with the measuring probe 24 has already reached the deepest measuring point in front of the borehole bottom 31 in the example of FIG. 1 by flushing with flushing liquid.
  • the core tube catcher 7 is still located in the straight part of the borehole 26.
  • the core rope 8 is braked by a winch 9 when entering the borehole 26 and when extending withdrawn from borehole 26.
  • the cable winch 9 is arranged next to a derrick 25, which is erected above the borehole 26.
  • the path of the core drill pipe 6 is measured via a drill path recorder 1 and stored in a correlated manner over time.
  • the energetically self-sufficient measuring probe 24 has a sensor part 22, which has a measurement-free access to the wall 30 of the borehole 26, 27 through the drill bit 2, in order to provide measurement data, for example about the nature of the rock 29 and the borehole wall 30 and the borehole caliber 28, to get.
  • Fig. 2 shows details of the core outer tube 4, which carries the drill bit 2 at one end and at the other end a lock 10 and a landing shoulder 11 are attached to fix the core inner tube 3.
  • FIG. 3 shows the details of the inner core tube 3, the outer dimensions of which allow insertion into the outer core tube 4.
  • a core catch sleeve 17 is screwed, which surrounds the core drilled during the drilling process with the core bit 2 from the rock 29 and, after completion of a drilling section, carries the core received by a core container 16 of the inner core tube 3, if this is with the core Core inner tube 3 for salvage from the borehole 26, 27 is brought over days.
  • the core sleeve 17 is unscrewed from the core inner tube 3 and the rock core is removed.
  • the measuring probe 24 is screwed onto the core inner tube 3 via a core catching sleeve adapter 20 instead of the core catching sleeve 17 and the latter washed back into the core drill pipe 6.
  • the core container 16 is connected at its other end to a core tube head 35, which carries a flushing head 15, to which a retractable housing 36 is connected in a variable-length manner via a threaded spindle 34, which consists of a rotary bearing part 14, a landing ring 13 and a bolt 12 and to which the Catch pin 5 is connected.
  • the landing ring 13 comes to rest when the core inner tube 3 is inserted into the core outer tube 4 on the landing shoulder 11.
  • the latch 12 of the core tube head 35 at the same time engages in the lock 10 of the core outer tube 4.
  • the core tube catcher 7 can be connected to the core inner tube 3 with the catch mandrel 5 if the core tube 3 is to be released from its anchoring and pulled out of the borehole 26.
  • the measuring probe 24 is shown in FIG. 4.
  • the general structure of the measuring probe 24 can be seen from this illustration. It consists of a sensor part 22 with a guide lug 23 and an induction coil 21 as well as the core catch adapter 20.
  • the sensor part 22 protrudes from the drill bit 2 during measurement.
  • a probe tube 32 is attached to the core sleeve adapter 20.
  • An electronic part 33 with data memory 19 and a battery 18 (as a power source) are contained in the probe tube 32. After connecting the measuring probe 24 to the inner core tube 3, the probe tube 32 is accommodated in a protected manner therein.
