- driving means for the drill bit which will normally comprise a so-called mud motor which obtains its power from the flow of drilling mud along the drill pipe.
- control means and drilling means may be manufactured as a unit, in which case the invention provides a drilling device including the driving means for the drill bit and the aforesaid control means.

- electronic means for measuring the components of the earths magnetic and/or gravitational fields, providing outputs which combine these measurements in a certain manner as defined by fixed signal processing within the control means or by remote drilling instructions, or by a combination of both.
- Drilling instructions may be given to the control means either by manual presetting of electrical controls before the control and drilling means are lowered into the well, or alternatively remotely by means which provide a communication link between the surface and the control means and which are dropped down the drill pipe.
- Such means are hereinafter referred to as a programme carrier," and the carrier may be settable to command specific servo angles or to provide on/off instructions, for example when the drilling angle is movable by the angle servo from zero to a predetermined limit of say 3 but is not adjustable to intermediate positions below that limit.
- Means may be provided to ensure that when it reaches the drilling device the programme carrier locates accurately in the angular sense with respect to a programme receiver embodied in the device at the trailing end thereof.
- the programme receiver identifies the specific command or commands set into the' carrier, and these commands may be defined by the angular positions of bar magnets ad justably mounted at the leading end of the carrier and the adjusted positions of which are sensed by flux gates or Hall effect devices in the receiver.
- FIG. 1 is a diagram showing the device attached to a drill pipe and a drill bit
- FIG. 2 is a diagram showing the method of alignment of a programme carrier of the device with respect to the drill pipe
- FIG. 3 is a block diagram of orientating servo means of the device.
- the device 1 comprises six sections disposed in line axially of the device and through which the drill mud passes, the trailing end of the device being rigidly attached to the bottom pipe section of the drill string 2.
- the leading section in this embodiment comprises a mud motor 8 which drives the drill bit 7 and is disposed immediately adjacent angle servo means 3 operable to set the drilling angle to zero, or alternatively to a fixed value which is typically 2. As the drilling angle is not adjustable to any other value the servo is controlled in an on/off mode by programming means as will be described.
- the angle servo means 3 are immediately followed by an electrical generator 4 driven by its own mud motor, and this is in turn followed by an electrical measuring device 5.
- This device measures the components of the earths magnetic and gravitational fields and derives outputs to control a following orientating servo means 6, whereby the latter are maintained at the position commanded by programme inputs from the surface or by preset inputs.
- the orientating servo 6 con trols orientation of the leading end of the device 1, and hence of the drill bit 7, with respect to the bottom end of the drill string 2.
- the trailing end section of the device comprises a programme receiver 9. It receives programming commands from a programme carrier 11 which provides a communications link between the surface and the drill. Angle and on-off commands are set into the carrier 11 by the mechanical, positioning of magnets such as 10 (FIG. 2) at the leading end of the carrier which is then dropped down the drill string 2 and falls freely under gravity until it reaches the drilling device 1.
- a mule- 'shoe 12 at the leading end of the carrier 1 l engages and locates with an inwardly projecting pin 13 in the bottom pipe section, whereby to orientate the program carrier 11 accurately with respect to the receiver 9.
- the latter incorporates magnetic field sensing devices which identify angular components and on-off commands set into the programme carrier 11.
- the angular component commands are used to control the orientation servo 6, while on-off commands are used to control the angle servo 3 and also may be used to ensure that the programme carrier 11 has located in the carrier position within the'drilling device 1.
- the device may incorporate a mud bypass valve which is operated in the event of non-location of the programme carrier and which acts to bypass the main mud motor.
- the device 1 provides a unit including the drilling motor 8 and the control means 3,4,5,6 and 9.
- the control means may be manufactured and supplied as a separate unit adapted for attachment to the drilling means.
- the electronic measuring device ensuring that the drill follows the command direction irrespective of torque wind-up in the drill string or any tendency of the drill bit to wander.
- the fact that it is unnecessary to estimate the pipe wind-up angle is a very great advantage, as is the facility to adjust the drilling angle to zero without coming out of the hole.
- Previous when changing from directional to straight drilling it has been necessary to withdraw the complete drill string and fit a new drilling device. In fact, with the present device it is only necessary to come out of the hole when it is necessary to change the drill bit.
- the trailing end of the programme carrier 11 has a projection 14 which can be engaged by a grab shoe on a line dropped down the drill string, thus enabling the programme carrier to be withdrawn for command resetting. While it is withdrawn a measuring instrument can be dropped down which provides information as to the inclination and direction of drilling.
- the orientating servo 6 of the present device uses the outputs from the sensing elements to rotate the drill with respect to the lower end of the drill pipe 2. Continuous orientation while drilling is achieved without the need for any type of transmission link to the surface.
- a block diagram of the orientation servo 6 is shown in FIG. 3, to which reference will now be made.
- This resolver may be either electro mechanical or electronic in its operation, but in either case it combines the input signals as follows:
- the output is a function of el e2 and an angular input such that Output e1 sina e2 cosa
- the resolver output is fed to a servo amplifier the output of which drives the orientating servo motor.
- This motor drives through a reduction gearbox to,
- the resolver input angle qb or mp may be either I preset before the drill is lowered into the well or may be set into the servo by means of the programme carrier.
- OXYZ is rotated about axis OZ by an angle ill, which will be defined as the AZIMUTI-I ANGLE.
- OXYZ is further rotated by a PITCH ANGLE 0 about the axis OY.
