Definitions

  • the present invention generally relates to drilling. More particularly, the present invention relates to wireline core drilling.
  • Wireline core drilling is often used in minerals exploration and geotechnical drilling.
  • wireline drilling systems In applications where deep holes are encountered, wireline drilling systems have been developed in order to cut down on the time spent in hoisting and lowering drill strings in order to take a core sample out.
  • the core sample can be removed from the bottom of the hole without removing the complete drill rod string assembly.
  • an overshot latching apparatus At the end of a core drilling operation, an overshot latching apparatus is lowered on a cable through the drill string until it reaches the core barrel. The overshot latching apparatus then latches onto a retractable inner tube assembly that is fixed in the core barrel during the core drilling operation. Upward pulling of the overshot latching apparatus triggers a release of the inner tube containing the core sample and which can then be hoisted up through the drill string.
  • the core sample when the rock being drilled is fractured or brittle, the core sample often has trouble properly entering the core barrel. If core sample blockage occurs, the inner tube assembly must be retrieved without a proper core sample and must be unblocked in order to reattempt a core drilling operation. In deep drilling operations, this retrieval of the inner tube assembly is time consuming and can cause delays in drilling operations.
  • One object of the present invention is to provide a core barrel assembly which addresses at least one of the above-mentioned needs.
  • a core barrel assembly for a drill string comprising:
  • the mechanical shock inducement mechanism induces a plurality of shocks to the inner tube assembly.
  • the mechanical shock inducement mechanism is actuated by drilling fluid circulating under pressure within the drill string.
  • the mechanical shock inducement mechanism is actuated and coupled to a rotation of the drill string.
  • the mechanical shock inducement mechanism is actuated by an electrical power source, such as a battery system.
  • the mechanical shock inducement mechanism is actuated by a pneumatic source.
  • the mechanical shock inducement mechanism is integrated with the inner tube assembly or core barrel assembly. In other implementations, the mechanical shock inducement mechanism is not integrated with the inner tube assembly or core barrel assembly.
  • the mechanical shock inducement mechanism comprises a hammer element being actuated and impacting the inner tube assembly upon an occurrence of a blockage within the inner tube assembly.
  • the hammer element can be actuated irrespective of the state of blockage of the inner tube assembly.
  • the mechanical shock inducement mechanism includes a turbine assembly, wherein drilling fluid circulating under pressure within the drill string actuates the turbine assembly thereby causing the turbine assembly to repetitively impact the inner tube assembly, preferably because of the presence of an eccentric feature in the turbine assembly, and upon occurrence of blockage in the inner tube assembly.
  • Figures 1A and 1 B are side and cut views respectively of a mechanical shock inducement mechanism according to an embodiment of the present invention in an open configuration
  • Figures 2A and 2B are side and cut views respectively of the mechanical shock inducement mechanism shown in Figures 1A and 1 B in a closed pre-shock configuration;
  • Figures 3A and 3B are side and cut views respectively of the mechanical shock inducement mechanism shown in Figures 1A and 1 B in a closed post- shock configuration

  • a mechanical shock inducement mechanism 10 for inducing at least one shock, and preferably a plurality of shocks, in an inner tube assembly according to an embodiment of the present invention.
  • the shock inducement mechanism 10 operates within core barrel assembly for a drill string.
  • the core barrel assembly includes a core barrel and an inner tube assembly 12 removably positionable within the core barrel 14 (note: the core barrel is only shown in Figures 9A to 9C).
  • the mechanical shock inducement mechanism 10 is actuated by drilling fluid circulating under pressure within the drill string. More particularly, the mechanical shock inducement mechanism 10 includes a hammer element 20 that is actuated and impacts the inner tube assembly 12 upon attainment of a built-up drilling fluid pressure within the drill string, as better shown in Figures 1 B/4B and 2B/5B. The built-up drilling fluid pressure is attenuated and released after impact of the hammer element 20 onto the inner tube assembly 12 as better shown in Figures 3B/6B.
  • this induced shock help reduce occurrences of blockage of core samples entering the inner tube assembly in fractured or brittle rock formations.
  • Figures 9A to 10C illustrate another embodiment of the present invention.
  • the mechanical shock inducement mechanism 10 is actuated and coupled to a rotation of the drill string. More particularly, the mechanical shock inducement mechanism 10 includes a sliding sawtooth clutch mechanism 40.
  • the spring 49 is compressed by backward movement of the inner tube assembly when blockage occurs in the inner tube. This backward movement causes the sliding sawtooth clutch mechanism to engage and to repetitively impact the inner tube assembly. These impacts combined with the compression of the spring push the inner tube assembly back into position. Hence core samples that are stuck in the inner tube assembly can be dislodged.
  • Figures 1 1 A to 1 1 C illustrate another embodiment of the present invention.
  • the mechanical shock inducement mechanism 10 includes a turbine assembly 51 , wherein drilling fluid circulating under pressure within the drill string actuates the turbine assembly 51 , thereby causing the turbine assembly 51 to repetitively impact the inner tube assembly, preferably because of the presence of an eccentric feature in the turbine assembly and upon an occurrence of blockage within the inner tube assembly.
  • a spring system can prevent the turbine assembly from contacting the hammer element and therefore not unnecessarily impact the inner tube in the absence of the blockage.
  • core samples that are stuck in the inner tube assembly can be dislodged.
  • the mechanical shock inducement mechanism comprises a hammer element being actuated and impacting the inner tube assembly through a device, other than a turbine assembly, upon an occurrence of a blockage within the inner tube assembly.
  • a device other than a turbine assembly
  • the mechanical shock inducement mechanism is actuated by an electrical power source, such as a battery system.
  • the mechanical shock inducement mechanism is actuated by a pneumatic source.
  • the mechanical shock inducement mechanism is integrated with the inner tube assembly or the core barrel assembly. In other implementations, the mechanical shock inducement mechanism is not integrated with the inner tube assembly or core barrel assembly.
