Definitions
- the present invention relates to a device for measuring the displacement of an injection head of a drilling mast, and, more particularly, to such a device which is intended to manage the position of the tool in the well as well that the coast bottom of this same well.
- a drilling mast to rotate a drill string.
- 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.
- the driller always needs to know the exact position of the elements of the drill string, and in particular the tool placed in the well in order to better manage the drilling.
- the classic way of knowing the position of the tool was simply to note the number of rods as well as the other elements of the packing - rod and stabilizers - used, and to deduce the total length. Given the large number of rods used, up to several hundred for deep drilling, the possibility of an error was significant.
- the present invention therefore relates to a device for measuring the displacement of an injection head of a drilling mast which is of simple, reliable construction and which makes it possible to know the position of the tool and the bottom coast in the borehole.
- the invention provides a device for measuring the displacement of the upper end of the drill string, the end being supported during drilling by a fastening assembly, movable along at least one rail guide, the measuring device comprising a sensor assembly mounted on the attachment assembly and comprising a roller adapted to roll on the rail during movement of the attachment assembly.
- FIG. 1 is a perspective view of a motorized injection head
- FIG. 1 is shown 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 an injection head 22 also fixedly mounted on the carriage 12. Conventionally, the injection head hangs 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, is the set of automatic keys 32 and 34 of the elevator 36.
- a sensor assembly 38 mounted on the carriage 12, is adapted to measure the displacement of the carriage relative to the rails 16.
- the sensor assembly 38 comprises a body 40, substantially cylindrical, on which a roller 42 is mounted. free to rotate.
- the sensor assembly 38 is mounted on the carriage 12 by means of a lever arm 44 which is mounted on a pivot 46, integral with the carriage 12.
- the arm of lever 44 is provided with a return spring (not shown) responsible for holding the sensor assembly 38 pressed against the rail 16.
- the sensor assembly 38 is shown in more detail in FIG. 2.
- the roller 42 comprises a metal hub 46 provided with an outer ring 48, for example synthetic rubber.
- the sensor assembly 38 comprises a body 50 in which a shaft 52 is mounted in rotation by means of two bearings 54 and 56.
- the roller 42 is mounted fixed at one end of the shaft 52, the other end of which comprises a perforated disc 58 of an optical encoder whose electronics are shown diagrammatically at 60.
- a light source and a photosensitive cell 61 are arranged on either side of the perforated disc 58.
- the perforated disc comprises 1000 sectors / tower.
- the signals generated by the optical encoder 60 are sent, by a cable 62, to a processing center (not shown), distant from the drilling mast.
- the sensor assembly 38 meets the explosion protection standards.
- the optical encoder 60 provides two quadrature signals which make it possible to calculate the length of the displacement of the sensor assembly relative to the rail 16, as well as its meaning.
- the signals coming from the optical encoder 60 join a set of up / down counters controlling a 16-bit digital-analog converter indicating the movement of the carriage with a resolution of less than one mm.
- Two fixed marks shown diagrammatically at 64 and 66 are mounted at the ends of the rail 16.
- a mechanical member not shown in the diagrams actuates an electrical contactor when passing in front of these marks.
- the electronic counting system only resets when going from top to bottom to avoid generating errors specific to mechanical hysteresis.
- Mark 66 at the bottom is intended to check and, if necessary, correct the signals indicating that the carriage 12 has reached its extreme position.
- the upper mark 64 makes it possible to compensate for any wear of the roller 42 comparing the distance measured between the two marks 64, 66 with the real distance and by adapting the sensor gain factor accordingly.
- the measuring device according to the invention can also be used on a drilling mast provided with a rotary table provided that the mast is equipped with at least one guide rail for the movable block on which the roller 42 can slide. the sensor assembly.
- the measuring device makes it possible to measure with great precision the movements of the carriage 12 as well as its direction and to be able to deduce therefrom the exact position of the tool in the well. Thanks to its high precision, it integrates perfectly into an automatic management system for lowering the packing and adding rods.
- the device can also be used on a floating offshore drilling platform, provided that the signal processing center is also connected to a second sensor of the same type or not intended to measure the vertical displacement of the platform by relative to a fixed mark, for example the extension tube, more commonly called "riser”.
