Definitions

  • the present invention relates to an injection head provided with a dynamometric measuring assembly and, more particularly to such an injection head intended to rotate a drill pipe.
  • the first, and most classic, is the rotation table which is mounted on the floor of the drill mast and has a square or hexagonal opening intended to receive a drive rod of complementary section. The table is rotated and thus causes the rotation of the drill string.
  • the other type of device is the motorized injection head, where an electric or hydraulic motor, mounted adjacent to the movable block, is connected directly to the upper end of the drill string.
  • the motor is mounted on a carriage which slides on rails arranged vertically on the mast thus allowing the carriage to move while absorbing the torque generated during drilling.
  • dynamometric measurement assemblies which are intended to be mounted on the drill string in order to be able to measure the forces and capture the various vibrations of the latter which are generated during drilling and which can be characteristic of either behavior of the drill string, either the state of wear of the tool, or the type of rock being destroyed.
  • Document US-A-4,715,451 describes a drilling assembly comprising a motorized head and a drill rod element provided with a measuring assembly.
  • the drill pipe member is disposed at the upper end of the drill string.
  • the positioning of the dynamometric measuring assembly below the automatic key is a source of difficulty because, during certain maneuvers, for example the removal of only a few elements from the drill string while maintaining the circulation of the mud, first remove the measuring system. Additional time, resulting from this removal and reassembly of the measuring assembly, therefore adds to the maneuver.
  • the object of the present invention is to overcome these drawbacks by proposing a motorized injection head provided with a dynamometric measuring assembly which is simple, reliable in construction and which makes it possible to carry out all types of maneuvers without dismantling the measuring assembly. .
  • the invention proposes a motorized injection head, intended to drive in rotation a drill pipe, comprising a motor provided with a main shaft, an assembly of automatic key, an elevator and a dynamometric measurement assembly comprising at least one sensor, mounted on an extension of the main shaft, characterized in that the dynamometric measuring assembly is mounted adjacent to the engine outlet between the engine and the automatic key assembly.
  • FIG 1 a motorized injection head 10 fixedly mounted on a carriage 12 provided with rollers 14 which allow it to slide on two rails 16 arranged vertically and integral with the drilling mast (not shown).
  • the injection head 10 comprises an engine 18 which can be electric or hydraulic and which comprises a hollow main shaft 20 which is connected by a bearing to a head injection 22 also fixedly mounted on the carriage 12. Conventionally, the injection head is suspended from the hook 24 of the movable block 26 which is part of the mast winch (not shown).
  • the injection head 22 is supplied with mud, in a known manner, by a flexible conduit 28 connected to a source of pressurized mud (not shown). Below the motor 18, and connected thereto by torque transmission arms 30, are the automatic key assembly 32 and 34 of the elevator 36.
  • the dynamometric measurement assembly 38 is disposed between the motor 18 and the automatic key assembly 32 and the elevator 36.
  • the dynamometric measuring assembly represented at 38, comprises a hollow extension 40 of the main shaft 20 which comprises, at its lower end, a male thread 42 intended to cooperate with a female thread corresponding to the upper end of the drill string (not shown).
  • the dynamometric measurement assembly 38 comprises a series of sensors mounted fixed on its outer surface and forming a measurement assembly.
  • the assembly comprises two traction gauges 44 and 46, a pair 48, 50 of torsion gauges, a temperature gauge 52, a pair of longitudinal accelerometers 54, 56, and three transverse accelerometers 58, 60, 62.
  • the assembly is provided with a pressure sensor 64.
  • the data generated by the sensors are processed by an electronic conditioning circuit 66 which allows digital multiplexing of the signals.
  • the electronic circuit is connected to a pair of annular tracks 68, 70 arranged around the shaft 40.
  • a brush holder assembly 72 mounted in rotation relative to the shaft 40, is intended to pick up the signals from the annular tracks 68 , 70.
  • This assembly 72 is connected to a connector 74 disposed on a flange 76 also mounted free to rotate on the shaft 40, the whole forming a rotating collector assembly.
  • the signals are sent to a processing center distant from the drill mast by an ordinary transmission cable 78.
  • the signals can be sent by radio or by magnetic induction.
  • a sheath 80 is intended to be mounted on the flange 76 to protect the various sensors.
  • a centralized measuring assembly is arranged integrally in the motorized injection head so as not to require additional maneuvering on the part of the driller.
