Definitions
- the present invention relates to a brake control device and method for a drilling platform, as well as to an automatic drilling system implementing such a device.
- the field of the invention is more particularly that of rotary table type oil drilling and / or "top drive” type drilling.
- the "rotary” system usually comprises an injection head, a drive rod which passes through a rotary table and which is connected to a drill string, and at the end of the train, a drilling tool digging the ground.
- the drive rod, and in fact the drill string and the tool at the end of the train, all rotate through the rotation table and an angular section of the column which is at the table, or if the table is not the means of rotation of the drilling machine, via the injection head which also serves to drive the column.
- the invention could also be applied in the field of geothermal drilling. State of the prior art
- the drill string which includes at its lower end the drilling tool, is hooked to a drill hook whose movement is controlled by a drilling winch.
- the drill winch includes a brake to prevent unwanted unwinding of the winch cable.
- the operator called the postmaster, uses a device, called a brake control, to maneuver loads or tools down into the wellbore.
- the brake control thus makes it possible to control the speed and the deceleration of the drill hook, possibly stopping the movement of the latter.
- the brake is a mechanical band brake.
- This brake consists of two metal strips equipped with internal fittings fixed by bolts of copper or aluminum with embedded head. These bands are connected by a balancing bar which also distributes the braking force between the two bands and thus reduces the wear of the pads.
- Each band wraps a rim solidary with drum. One end of each band is fixed while the other is connected via a set of cams and links to an articulated lever, - the brake control - which allows to increase the effort that one exerts on its end.
- the brake is a disc brake.
- the brake control is made in the form of a joystick.
- a brake control in the form of an articulated lever - also called a brake bar - or in the form of a disc brake
- manual control of the brake control by the station manager can lead to lack of precision in the actuation of the brake control which leads to an underperformance of the advance of drilling and premature wear of the drill bit.
- An error of the head of post can lead to the destruction of the drilling tool, see the loss of the well.
- An object of the invention is therefore to provide a device and a system and a method of automating the brake control.

- the introduction of fluid into the cylinder displaces the piston, causing the brake control to move to modulate the force on the brake.
- the force exerted by the piston on the brake control must exceed that of the spring restoring force.
- the emergency braking is carried out by emptying the fluid contained in the cylinder into the atmosphere, which causes the piston to descend into the cylinder and then return it by the spring of the brake control. It should be noted that such an emptying of the fluid contained in the cylinder can induce risks of pollution and be toxic.
- EP0694114 also discloses a primary brake in the form of a belt brake a priori manually operable by a brake control.

- the electronic control means 41 are arranged to slave the actuating means 32 to a movement speed setpoint of the end 30 of the brake bar 24.
- a speed control allows the operator to find sensations close to the one he can have in manual drilling. This is true in a braking mode as in the unwinding mode of the cable C.
- the braking mode is defined as an operating mode of the device 40 according to the invention in which the brake bands 25a, 25b act on the drum 21 to exert a braking force. In this mode, the device 40 according to the invention partially prevents the rotation of the drum 21. The braking force may be such that the rotation of the drum 21 is stopped.
- the device 40 further comprises a punch-type emergency device whose function is to cut off any servocontrol of the control bar 40 and thus allow the purely manual retraction of the control bar 40.
- the electronic control means 41 are arranged to control the actuating means 32 at a thrust force instruction in a braking mode.
- the electronic control means 41 are arranged to slave the actuating means 32 to a position command of the brake bar 24.
- the actuating means 32 are supplied with energy by an inverter 44 comprising means for detecting the interruption of the power supply.
- the electronic means 41 are configured to control the actuating means 32 to actuate them in the direction of braking during a detection of power failure by the power cut detection means.
- the direction of braking is of course the direction for which the device 40 according to the invention partially prevents the rotation of the drum 21.
- control device 40 may comprise alternately or in addition a stress sensor for measuring a stress on the second control handle 33.
- This sensor For example, the constraint constraint can be implemented by a strain gauge.
- the brake control 40 comprises a brake bar 24 having a first end 29 mechanically connected to brake bands 25a, 25b provided to act on the drum 21 and a second end 30 provided with a first brake control handle 31.
- the method comprises:
- the applied force being controlled to provide a servo of the position of the brake bar 24 and / or a thrust force exerted on the brake bar 24,
- the servo-control of the brake bar 24 provided by an actuator 32 controlled from an electronic control unit 41 arranged to process the control signal generated from the second control handle S1 and / or information relating to operating conditions of the winch 2,
- the information processed by the electronic control unit 41 comprising information relating to the weight applied to the tool 3 and / or to the differential mud pressure at the tool 3 and / or the maximum torque in rotation supported by the tool 3 and / or the maximum speed of penetration of the tool into the ground.
- a part and / or all of the information collected by the central unit 41 may be deported to a control center remote from the platform 1.
- the signal relating to the collected information may for example be transported over the Internet to a network. center of expertise via a cable or satellite link.
- a control signal added to control the actuating means 32 via the central unit 41 may come from a control center remote from the platform 1.
- the added signal may for example be carried by the network Internet.
- the hand of an operator can be advantageously replaced by any object arranged to exert a force and / or a pressure on the second control handle 33.
- an object can be an actuator on the control handle driven to remote.
- the signals S2 and S3 can be advantageously used to respectively read the instantaneous weight on the tool 3 and read the parameter of the desired weight on the tool, ie the target weight on the tool, which has been set by the operator via a wheel included in the indicator 36.
- the setting of the target weight by the operator is thus via the wheel of the indicator 36 and not via the potentiometric settings.
- the same arrangement can be made on a device indicating the differential slurry pressure.
