Definitions
- ABSTRACT A drilling head attachable to a drill pipe for directional drilling in a borehole is arranged to be rotatable with respect to the drill pipe and to be held in required orientation against the drill reaction torque, by clutch means or by a torque balancing force.
- a counter torque maybe set up by rotation .of the drill pipe and applied as the torquebalancing force.
- a loaded pump driven by the drill pipe is suitable for producing the counter torque, the loading being adjustable by restricting shunt flow or by varying the loading of an electricla generator driven by a hydraulic motor supplied by the pump.
- the orientation is measured as an angle in a gravitational and/or geomagnetic frame of reference in a control circuit including a sensor unit located in the drilling head, the control circuit being preset 0r programmed or subject to command from the surface to hold the head at the required orientation.
- This invention relates to directional drilling and to methods of and means for drilling and for directional control of drilling with a drilling head mounted at the lower end of a drill pipe or string.
- a drilling head comprising a hydraulic motor or mud motor driving a drill bit is rigidly fixed at the lower end of the drill pipe, either aligned with or slightly inclined to the axis of the drill pipe at that end.
- Change of direction can be effected with an inclined head suitably orientated by rotating the drill pipe from the surface, although difficulty arises in setting the orientation due to wind-up" in the drill pipe.
- the present invention is concerned particularly with the orientation and control of orientation of a drilling head.
- a drilling head attachable to a drill pipe for directional drilling in a bore hole is arranged to be rotatable with respect to the drill pipe and to be held in required orientation against the drill reaction torque.
- the drilling head particularly a mud motor in a housing, tends to rotate bodily with respect to the working drill bit on the head and so to be power driven progressively to change its orientation.
- the head can be held in a required orientation and against further rotation, for example by clutching or by a torque balancing force.
- the orientation may be measured as an angle in a gravitational and/or geomagnetic frame of reference in a control circuit including a unit located in the head containing sensors of earth field objects and the control circuit may be preset or programmed or subject to command from the surface to hold the head at a required orientation or sequence of orientations.
- a counter torque may be set up by rotation of the drill pipe and applied as the torque balancing force for holding the head in a required orientation.
- the counter torque may be the reaction torque in a loaded pump adapted to be driven by rotation of the drill pipe.
- the counter torque is then adjustable by varying the loading to reach a balanced torque condition at a desired orientation.
- the load for the pump may be provided by a hydraulic motor in a closed fluid circuit with the pump and coupled to drive an electrical generator.
- the electrical load on the generator can then be varied electronically under the control of the control circuit.
- the generator may be arranged to supply the instrument power necessary for the control circuit.
- the invention also provides a method of or means for adjustably controlling the orientation of a drill motor at the lower end of a drill pipe in a bore hole, wherein the drill reaction torque upon the drill motor is opposed by a controlled torque derived from rotation of the drill pipe.
- the controlled torque may be provided by an adjust able hydraulic torque-changing device interposed between the drill pipe and the drill motor. Rotation of the drill pipe relative to the drill-motor housing may be applied to pump hydraulic fluid in a circuit in which the resistance to fluid flow can be varied.
- the resistance to fluid flow may be provided by controlled pressurereducing orifices or flow paths shunting the pump or by said hydraulic motor.
- the invention further provides means for controlling the orientation of a drill motor carried at the drilling end of a drill pipe in a bore hole, wherein the drill reaction torque on the drill motor is conteracted by a torque-changing or torque-adjusting means adapted to be driven by rotation of the drill pipe and controlled by orientation measuring means associated with the drill motor.
- the torque-changing or adjusting means preferably includes a variably loaded electrical generator which generator supplies instrumentation power for the orientation measuring means controlling the loading of the generator.
- the control means required for installation at the lower end of a drill pipe carrying a drill motor may comprise an orientation measuring unit including sensors of components of the earth magnetic and/or gravitational fields and a variable electrical or hydraulic resistive load controlled by said measuring unit whereby in use the load may be automatically adjusted for the purpose of providing a torque to balance the drill reaction torque at a required orientation of the mid-plane motor.

- FIG. 2 is a block diagram of one arrangement for controlling theorientation of a drilling head in the installation of FIG. 1,
- FIG. 3 is a block diagram of an alternative arrangement for controlling the orientation
- FIG. 4 is a cross-sectional view of a particular form of hydraulic pump which may be used in the installation of FIG. 1 with orientation control as in FIG. 2 or 3.
- the drilling arrangement as a whole is generally similar to that described in the specification of my aforesaid previous application in that it comprises, as shown in FIG. 1, a drill pipe string with a mud-motor 2 and drill bit 3 at the lower end.

- the structure constituting the drilling head 8 includes a pipe section 9 axially rotatable within the pipe section 7 and having a suitable form of thrust bearing therein, diagrammatically represented as a bearing 10.
- a pair of sealed tapered-roller-bearings are provided at or near the respective ends of the pipe-section 9 for rotation of that pipe section and to take the thrust and lateral loads.
- An orientating servo system is provided in a form to be described hereinafter and a programme receiver (not shown) may be included to receive drilling commands from a programme carrier lowered down the drill string 1 and arranged to come into predetermined alignment with the receiver.
- the orientating servo system is arranged to hold the drilling head against the reaction torque and in required orientation determined by the measuring device 6 which establishes a frame of reference, and by commands injected into the measuring device.
- the latter controls the angle servo means as in the aforesaid prior specification and it also controls the orientating servo system.
- the orientating servo system in its simplest form may consist of a power-operated clutch effective when the actual orientation reaches the demanded orientation, and such an arrangement will be further described hereinafter.
- a counter torque is set up and the orientating servo system functions to balance the reaction torque and the counter torque at the demanded orientation.
- provision is made at the surface for continuously rotating the drill pipe the speed of rotation being preferably in the range of to 50 rpm.
- the means for continuously rotating the drill pipe may be as already in use for rotating a drill string to reach a desired orientation ofa conventional mud-motor-drilling head, namely a kelly comprising squared section of pipe 11 disposed abovesurface and longitudinally movable, with the drill string, in a power-driven rotatable table 12 with a central square aperture. It will be noted that rotation of the drill pipe makes it possible to change the orientation of the drilling head in the reverse sense to change due to the drill reaction torque.
- the counter torque is applied by interposing between the drill pipe 7 and the drilling head 8 a hydraulic controlled torque device.
- the latter is in the form of a hydraulic pump 13, body-mounted in the pipe section 9 with a clearance provided by ribs 14, and having an input shaft 15 coupled by means of an apertured transverse plate 16 to the drill pipe 7 to be driven thereby.

- the pump input shaft 15 rotates with the drill pipe 7 and the pump body is subject to the drill reaction torque, as will be clear from FIG. 1, the reaction torque being shown in FIG. 2 as applied to a shaft 31 representing the body to the pump 13.
- the pressure drop in the load circuit of the pump 13 is produced in a series of constricted paths 32 in parallel and controlled by electrically operated stop valves 33.
- the path constrictions are conveniently provided by orifices in the stop valves.
