Description

La présente invention concerne un dispositif pour assurer la verticalité en cours de forage d'un engin de perforation et plus particulièrement pour le contrôle de la verticalité d'un tel engin comprenant un châssis suspendu sur lequel est montée une tête de forage.The present invention relates to a device for ensuring the verticality during drilling of a perforating machine and more particularly for controlling the verticality of such a machine comprising a suspended chassis on which is mounted a drilling head.

Des engins de ce type, suspendus par exemple à un câble, à un flexible ou à des tiges, sont notamment utilisés sur les chantiers de pétrole et pour l'exécution de fondations dans tous types de terrains durs ou tendres. Au début du forage, le châssis servant de guide et/ou la simple gravité permettent d'assurer la verticalité de l'engin. Toutefois, lorsque ce châssis est entièrement enfoncé en-dessous de la surface terrestre, et que les variations de dureté du terrain tendent à le dévier, on ne dispose d'aucun moyen mécanique direct permettant de contrôler la verticalité de l'engin et donc du forage.Machines of this type, suspended for example from a cable, a hose or rods, are used in particular on oil sites and for the execution of foundations in all types of hard or soft ground. At the start of drilling, the chassis serving as a guide and / or simple gravity ensures the verticality of the machine. However, when this chassis is fully sunk below the earth's surface, and the variations in hardness of the ground tend to deflect it, there is no direct mechanical means available to control the verticality of the machine and therefore the drilling.

La présente invention vise à palier cet inconvénient en fournissant un dispositif permettant de contrôler la verticalité d'un engin de perforation à tout instant, y compris lorsque cet engin se trouve entièrement en-dessous de la surface du sol.The present invention aims to overcome this drawback by providing a device making it possible to control the verticality of a perforating device at any time, including when this device is entirely below the surface of the ground.

A cet effet, l'invention prévoit un dispositif pour assurer la verticalité d'un engin de perforation comprenant un châssis suspendu sur lequel est montée une tête de forage, caractérisé par le fait que ladite tête de forage est fixée sur un organe de liaison relié de façon orientable à un organe de support solidaire du châssis.To this end, the invention provides a device for ensuring the verticality of a perforating machine comprising a suspended chassis on which is mounted a drilling head, characterized in that said drilling head is fixed on a connected connecting member orientably to a support member secured to the chassis.

La verticalité du forage peut ainsi être assurée en orientant de façon convenable la tête de forage par rapport au châssis, grâce a un déplacement relatif de l'organe de liaison par rapport à l'organe de support.The verticality of the drilling can thus be ensured by suitably orienting the drilling head with respect to the chassis, by virtue of a relative displacement of the connecting member with respect to the support member.

Dans un mode de réalisation préféré de l'invention, l'organe de liaison et l'organe de support sont deux plaques métalliques normalement en contact l'une avec l'autre, des moyens étant prévus pour écarter dans une direction choisie la plaque de liaison de la plaque de support.In a preferred embodiment of the invention, the connecting member and the support member are two metal plates normally in contact with each other, means being provided for moving the plate in a chosen direction support plate connection.

Ces plaques peuvent par exemple être sensiblement horizontales.These plates can for example be substantially horizontal.

..Dans un mode de réalisation particulier de l'invention, la plaque de liaison est montée sur la plaque de support par l'intermédiaire d'au moins deux organes élastiques opposés chacun à un vérin par rapport à la direction de l'orientation...In a particular embodiment of the invention, the connecting plate is mounted on the support plate by means of at least two elastic members each opposed to a jack with respect to the direction of orientation.

Ainsi, lorsque l'on actionne l'un des vérins pour orienter convenablement la plaque de liaison par rapport à la plaque de support, l'organe élastique situé du même côté que ce vérin se déforme dans une première direction pour permettre l'écartement des plaques, alors que l'autre organe élastique se déforme dans une seconde direction en formant charnière.Thus, when one of the jacks is actuated to properly orient the connection plate relative to the support plate, the elastic member located on the same side as this jack deforms in a first direction to allow the spacing of the plates, while the other elastic member deforms in a second direction forming a hinge.

Les organes élastiques peuvent comprendre un goujon traversant avec jeu une des plaques et vissé dans l'autre plaque avec interposition d'éléments compressibles.The elastic members may include a stud with clearance through one of the plates and screwed into the other plate with the interposition of compressible elements.

Le goujon peut traverser avec jeu soit la plaqué de liaison soit la plaque de support en étant vissé respectivement dans la plaque de support ou dans la plaque de liaison, les éléments compressibles pouvant être interposés, soit entre la tête du goujon et la plaque traversée avec jeu, soit entre les deux plaques.The stud can pass through either the connecting plate or the support plate with clearance by being screwed respectively into the support plate or into the connection plate, the compressible elements being able to be interposed, either between the head of the stud and the plate traversed game, either between the two plates.

Les éléments compressibles peuvent par exemple comprendre un empilement de rondelles Belleville.The compressible elements may for example comprise a stack of Belleville washers.

De préférence la compression maximale possible des éléments compressibles est limitée par une douille engagée sur le goujon en parallèle avec ces éléments.Preferably the maximum possible compression of the compressible elements is limited by a sleeve engaged on the stud in parallel with these elements.

Avantageusement le corps du vérin peut être formé par un trou percé dans une des plaques, dans lequel est placé un piston, ledit trou débouchant dans la face de cette plaque en vis-à-vis de l'autre plaque.Advantageously, the body of the jack can be formed by a hole drilled in one of the plates, in which a piston is placed, said hole opening out into the face of this plate opposite the other plate.

Cette disposition assure un encombrement minimal puisque les vérins sont intégrés dans une des plaques, ce qui assure de plus leur protection vis-à-vis du milieu extérieur.This arrangement ensures minimal bulk since the jacks are integrated in one of the plates, which also ensures their protection vis-à-vis the external environment.

Cette protection peut également être assurée par une jupe en matériau élastique tel que du caoutchouc, disposée autour des deux plaques pour empêcher la pénétration de la boue de forage lors de l'écartement des plaques.This protection can also be provided by a skirt made of elastic material such as rubber, disposed around the two plates to prevent the penetration of the drilling mud during the spacing of the plates.

Le dispositif selon l'invention peut être en particulier adapté au contrôle de la verticalité d'un engin de forage dont la tête de forage comprend une paire d'outils tournant en sens inverse de sorte que la verticalité de l'engin de forage est assurée dans le plan de rotation des outils par un ajustement de la différence de vitesse de rotation des outils. Dans ce cas, l'organe de liaison peut être monté pivotant par rapport à l'organe de support autour d'au moins un axe horizontal parallèle au plan de rotation des outils.The device according to the invention can in particular be adapted to control the verticality of a drilling rig whose drilling head comprises a pair of tools rotating in opposite directions so that the verticality of the drilling rig is ensured in the tool rotation plane by adjusting the difference in tool rotation speed. In this case, the connecting member can be pivotally mounted relative to the support member around at least one horizontal axis parallel to the plane of rotation of the tools.

Ainsi, on peut faire basculer la tête de forage de part et d'autre du plan moyen de rotation des outils, afin de contrôler la verticalité de l'engin de forage dans la direction perpendiculaire à ce plan.Thus, the drilling head can be tilted on either side of the mean plane of rotation of the tools, in order to control the verticality of the drilling machine in the direction perpendicular to this plane.

Dans ce cas, le dispositif peut comprendre deux rangées d'organes élastiques disposées de part et d'autre du plan médian du dispositif parallèle au plan de rotation des outils.In this case, the device can comprise two rows of elastic members arranged on either side of the median plane of the device parallel to the plane of rotation of the tools.

Le pivotement de la tête de forage s'effectue alors en fonction de sa direction, autour de l'un ou l'autre des axes matérialisés par les rangées d'organes élastiques.The pivoting of the drilling head then takes place as a function of its direction, around one or other of the axes materialized by the rows of elastic members.

On décrira maintenant à titre d'exemple non limitatif un mode de réalisation particulier de l'invention en référence aux dessins schématiques annexés dans lesquels :

  • La figure 1 est une vue de face d'un engin de perforation comportant un dispositif de contrôle de la verticalité conforme à la présente invention.
  • La figure 2 en est une vue de-dessus.
  • La figure 3 en est une vue de profil.
  • La figure 4 est une vue en coupe selon la ligne IV-IV de la figure 1.
  • La figure 5 est une vue en coupe selon la ligne V-V de la figure 1 à une plus petite échelle que la figure 4.
  • La figure 6 est une vue de-dessus de la plaque de liaison.
A particular embodiment of the invention will now be described by way of nonlimiting example with reference to the appended schematic drawings in which:
  • Figure 1 is a front view of a perforating device comprising a verticality control device according to the present invention.
  • Figure 2 is a top view.
  • Figure 3 is a side view.
  • Figure 4 is a sectional view along line IV-IV of Figure 1.
  • FIG. 5 is a sectional view along the line VV of FIG. 1 on a smaller scale than FIG. 4.
  • Figure 6 is a top view of the connecting plate.

L'engin de perforation représenté aux figures 1 à 3 comporte de façon connue un châssis 1 suspendu par un organe 2 à un engin de levage et supportant une tête de forage 3 qui comporte deux paires jumelles d'outils 4 et 4', chaque paire d'outils étant entraînée par un moteur hydraulique alimenté à partir de la surface par des canalisations 5.The perforating machine shown in Figures 1 to 3 comprises in known manner a frame 1 suspended by a member 2 to a lifting machine and supporting a drilling head 3 which comprises two twin pairs of tools 4 and 4 ', each pair of tools being driven by a hydraulic motor supplied from the surface by pipes 5.

Les deux paires d'outils 4 et 4' tournent en sens inverse, comme indiqué par les flèches sur la figure 1.The two pairs of tools 4 and 4 ′ rotate in opposite directions, as indicated by the arrows in FIG. 1.

En faisant varier la vitesse relative de rotation des paires d'outils 4 et 4', il est possible de jouer sur la progression de l'engin de forage dans le plan de rotation des outils. Si l'on souhaite par exemple faire dévier l'engin de forage vers + X (figure 2) on fait tourner la paire d'outils 4' plus vite que la paire d'outils 4.By varying the relative speed of rotation of the pairs of tools 4 and 4 ′, it is possible to influence the progression of the drilling machine in the plane of rotation of the tools. If, for example, we wish to deflect the drilling rig towards + X (Figure 2) we rotate the pair of tools 4 'faster than the pair of tools 4.

On décrira maintenant en détail, en référence à la figure 4, les moyens permettant de jouer sur la verticalité de la descente de l'engin de forage dans la direction Y perpendiculaire au plan de rotation des outils.We will now describe in detail, with reference to Figure 4, the means for playing on the verticality of the descent of the drilling machine in the direction Y perpendicular to the plane of rotation of the tools.

Une plaque de support 6 soutenant la tête de forage 3 est fixée à la partie inférieure du châssis 1.A support plate 6 supporting the drilling head 3 is fixed to the lower part of the chassis 1.

Une plaque de liaison 7 est fixée sous la plaque 6 de la manière suivante :A connecting plate 7 is fixed under the plate 6 as follows:

Deux rangées de filetage 8 sont réalisées dans la plaque 7 de part et d'autre de l'axe de symétrie X-X du dispositif. En correspondance avec ces filetages sont réalisés, dans la plaque 6, des trous 9 de diamètre supérieur au diamètre nominal des filetages 8.Two rows of threads 8 are produced in the plate 7 on either side of the axis of symmetry X-X of the device. In correspondence with these threads, holes 9 are made in the plate 6 with a diameter greater than the nominal diameter of the threads 8.

Des goujons .filetés 10 sont vissés dans les filetages 8 en traversant avec jeu la plaque 6 à travers les trous 9. Un empilement de rondelles'Belleville 11 est intercalé entre la tête 12 de chaque goujon 10 et la surface supérieure de la plaque 6. Cet empilement est protégé à l'extérieur par une gaine de caoutchouc 13..Filetés of studs 10 are threaded into the threads 8 in passing with clearance through the plate 6 through the holes 9. A stack of washers' Belleville 11 is interposed between the head 12 of each stud 10 and the upper surface of the plate 6. This stack is protected outside by a rubber sheath 13.

Du fait de l'elasticité de l'empilement de rondelles 11, la face supérieure de la plaque 7 est normalement appliquée contre la face inférieure de la plaque 6. Néanmoins, cet empilement de rondelles étant compressible, les deux plaques peuvent être écartées l'une de l'autre. Cet écartement est toutefois limité par des douilles 14 disposées entre les goujons 10 et les rondelles 11 qui limitent l'écartement à une valeur E telle que représentée à la figure 4.Due to the elasticity of the stack of washers 11, the upper face of the plate 7 is normally applied against the lower face of the plate 6. However, this stack of washers being compressible, the two plates can be spaced apart. one of the other. This spacing is however limited by sockets 14 arranged between the studs 10 and the washers 11 which limit the spacing to a value E as shown in FIG. 4.

De plus, du fait que les goujons 10 traversent les trous 9 avec jeu, la plaque 7 peut s'écarter de la plaque 6 en formant un certain angle comme cela apparaît à la figure 5 où l'or voit que les goujons 10 et les trous 9 sont désaxés.In addition, since the studs 10 pass through the holes 9 with play, the plate 7 can move away from the plate 6 at an angle as shown in FIG. 5 where the gold sees that the studs 10 and the holes 9 are offset.

Un autre ensemble de goujons 15 engagés dans des filetages 15' (figure 6) assurent la fixation sur la plaque de liaison 7 de la plaque 26 elle-même solidaire d'une armature 16 à laquelle est fixée la tête de forage.Another set of studs 15 engaged in threads 15 ′ (FIG. 6) ensures the attachment to the connecting plate 7 of the plate 26 itself secured to a frame 16 to which the drilling head is fixed.

Les têtes de forage proprement dites ne sont pas représentées aux figures 4 et 5, mais on voit néanmoins sur la figure 5 la buse 17 d'aspiration des résidus de forage et le conduit 18 qui les achemine vers la surface du sol.The drilling heads themselves are not shown in FIGS. 4 and 5, but in FIG. 5 the nozzle 17 for suction of the drilling residues and the conduit 18 which routes them to the ground surface are nevertheless seen.

L'écartement des plaques de support 6 et de liaison 7 est provoqué par deux rangées de vérins hydrauliques 19 intercalées respectivement avec les trous filetés 8 de chacune des rangées de trous.The spacing of the support plates 6 and connection 7 is caused by two rows of hydraulic cylinders 19 interposed respectively with the threaded holes 8 of each of the rows of holes.

Les vérins 19 sont réalisés directement par perçage de la plaque 7, ces perçages débouchant du côté de cette plaque en vis-à-vis avec la plaque 6. Dans ces perçages, sont placés des pistons 20 qui sont susceptibles d'être déplacés par un fluide hydraulique amené par des canalisations 21 et 21-' alimentant simultanément tous les vérins 19 d'une même rangée.The jacks 19 are produced directly by drilling the plate 7, these holes opening out on the side of this plate opposite the plate 6. In these holes, are placed pistons 20 which are capable of being displaced by a hydraulic fluid supplied by pipes 21 and 21- 'simultaneously supplying all the jacks 19 of the same row.

On constate ainsi que si l'on alimente en fluide sous pression la canalisation 21', on incline la plaque 7 de la manière représentée à la figure 5 de sorte que la tête de forage s'oriente selon l'angle + a de la figure 3, ce qui a pour effet de dévier l'engin de forage dans la direction + Y. Inversement, si l'on alimente en fluide la canalisation 21, la tête de forage bascule vers l'angle -α de sorte que l'engin de forage s'oriente vers la direction - Y.It can thus be seen that if the pipe 21 ′ is supplied with pressurized fluid, the plate 7 is inclined as shown in FIG. 5 so that the drilling head is oriented at the angle + a of the figure 3, which has the effect of deflecting the drilling machine in the + Y direction. Conversely, if the pipe 21 is supplied with fluid, the drilling head switches towards the angle -α so that the machine drilling moves in direction - Y.

Afin d'éviter l'entrée dans le dispositif de boue de forage lors de . l'écartement des plaques 6 et 7, une jupe en caoutchouc extensible 22, est disposée tout autour des deux plaques 6 et 7. De plus, des joints toriques 23, 23' sont prévus dans des zones évidées des plaques 6 et 7, ces joints étant comprimés comme représenté à la figure 4 lorsque les plaques 6 αt 7 sont en contact et se dilatant comme représenté à la figure 5 lorsque les plaques 6 et 7 sont écartées l'une de l'autre.To prevent entry into the drilling mud device during. the spacing of the plates 6 and 7, an extensible rubber skirt 22, is arranged all around the two plates 6 and 7. In addition, O-rings 23, 23 ′ are provided in the recessed areas of the plates 6 and 7, these seals being compressed as shown in Figure 4 when the plates 6 αt 7 are in contact and expanding as shown in Figure 5 when the plates 6 and 7 are spaced from each other.

Enfin, des clapets anti-retour 24 sont prévus pour permettre l'équilibrage des pressions lorsque, les deux plaques 6 et 7 étant écartées, elles sont progressivement ramenées en contact l'une avec l'autre.Finally, non-return valves 24 are provided to allow pressure balancing when, the two plates 6 and 7 being separated, they are gradually brought back into contact with one another.

Le dispositif ainsi décrit peut facilement être asservi à l'indication d'un inclinomètre 25 situé sur le châssis 1 (figure 1). La vitesse différentielle des outils 4 et 4' est régulée afin d'orienter l'engin de forage dans le plan X, alors que les vérins 19 sont alimentés en tout ou rien par les canalisations 21 ou 21' afin de jouer sur la verticalité dans le plan Y.The device thus described can easily be slaved to the indication of an inclinometer 25 located on the chassis 1 (FIG. 1). The differential speed of the tools 4 and 4 'is regulated in order to orient the drilling machine in the plane X, while the jacks 19 are supplied with all or nothing by the pipes 21 or 21' in order to play on the verticality in the Y plane.

Diverses variantes et modifications peuvent bien entendu être apportées au mode de réalisation décrit ci-dessus sans sortir pour autant du cadre ni de l'esprit de l'invention.Various variants and modifications can of course be made to the embodiment described above without departing from the scope or the spirit of the invention.
