Description

La présente invention est relative à un dispositif de manutention de tiges de forage, notamment pétrolier, dans une installation du type dans laquelle le système d'entraînement en rotation des tiges est placé directement sous le crochet de suspension.The present invention relates to a device for handling drill rods, in particular for oil, in an installation of the type in which the rod rotation drive system is placed directly under the suspension hook.

Dans ces installations le montage des tiges de forage nécessite des interventions manuelles parfois dangereuses.In these installations, the mounting of drill pipes requires manual interventions which are sometimes dangerous.

Un but de l'invention est d'éviter toute intervention manuelle.An object of the invention is to avoid any manual intervention.

Un autre but de l'invention est de réaliser un dispositif permettant de compenser automatiquement la variation de longueur du train de tiges, résultant du dévissage ou du vissage lors des opérations de forage.Another object of the invention is to provide a device making it possible to automatically compensate for the variation in length of the drill string, resulting from unscrewing or screwing during drilling operations.

L'invention a pour objet un dispositif de manutention de tiges de forage comprenant, suspendu à un crochet, un moteur associé à un réducteur et entraînant en rotation autour de son axe un arbre creux vertical relié à une canalisation d'amenée de boues de forage, caractérisé en ce qu'est disposé autour dudit arbre un vérin comprenant un cylindre solidaire de l'arbre et un piston annulaire ent"ainé en rotation avec l'arbre et pouvant effectuer des mouvements de translation parallèles audit axe, ledit piston étant prolongé hors du cylindre par une pièce d'extrémité tubulaire filetée à sa partie inférieure pour pouvoir se visser sur une tige de forage, le dispositif comprenant en outre, disposés dans le prolongement de la pièce d'extrémité, un jeu de griffes rétractables et un jeu de patins permettant respectivement de supporter et d'immobiliser en rotation le train de tiges, ce jeu de griffes et patins étant guidé contre des organes de guidage fixes en rotation et liés à un carter de protection de l'ensemble fixé à sa partie supérieure à l'ensemble moteur réducteur, lequel ensemble est immobilisé en rotation par un système de liaison à vérin et bielle permettant un déplacement latéral de l'ensemble du dispositif et le reliant à un chariot coulissant le long de pistes verticales fixes.The subject of the invention is a device for handling drill pipes comprising, suspended from a hook, a motor associated with a reduction gear and driving in rotation about its axis a vertical hollow shaft connected to a pipe for supplying drilling mud. , characterized in that there is disposed around said shaft a cylinder comprising a cylinder integral with the shaft and an annular piston ent " ain rotation with the shaft and capable of performing translational movements parallel to said axis, said piston being extended out of the cylinder by a tubular end piece threaded at its lower part to be able to be screwed on a drill pipe, the device further comprising, arranged in the extension of the end piece, a set of retractable claws and a set of pads allowing respectively to support and immobilize in rotation the drill string, this set of claws and pads being guided against guide members fixed in rotation and linked to a housing of pr otection of the assembly fixed at its upper part to the reduction motor assembly, which assembly is immobilized in rotation by a connection system with jack and connecting rod allowing lateral movement of the assembly of the device and connecting it to a sliding carriage along fixed vertical tracks.

De préférence l'arbre creux et le piston annulaire possèdent des cannelures verticales empêchant la rotaton du piston.Preferably the hollow shaft and the annular piston have vertical grooves preventing rotation of the piston.

Avantageusement, une vanne est interposée entre le piston annulaire et la pièce tubulaire d'extrémité.Advantageously, a valve is interposed between the annular piston and the tubular end piece.

L'invention va être précisée par une description détaillée d'un mode préféré de réalisation de l'invention, en référence au dessin annexé dans lequel

  • - la figure 1 représente une vue générale d'un derrick équipé d'un dispositif de manutention de tiges selon la présente invention
  • - la figure 2 est une vue en élévation et demi-coupe partielle du dispositif de manutention selon l'invention
  • - la figure 3 est une vue en coupe agrandie d'une partie du dispositif.
The invention will be clarified by a detailed description of a preferred embodiment of the invention, with reference to the accompanying drawing in which
  • - Figure 1 shows a general view of a derrick equipped with a rod handling device according to the present invention
  • - Figure 2 is an elevational view and partial half-section of the handling device according to the invention
  • - Figure 3 is an enlarged sectional view of part of the device.

La figure 1 représente une vue générale d'un derrick destiné au forage.Figure 1 shows a general view of a derrick intended for drilling.

On distingue la structure du derrick 1 posée au sol 2. Un train 3 de tiges doit être rallongé par un ensemble 4 de tiges préassemblées (trois tiges par exemple) grâce au dispositif de l'invention. Le dispositif permet aussi de démonter une tige ou un ensemble de tiges du train de tiges. Les ensembles de tiges préassemblées telles que celle représentée 5 sont stockées verticalement dans une zone 6 ; le dispositif 7 d'entraînement et de manutention des tiges est suspendu à un crochet 8 placé à la partie supérieure du derrick, le crochet étant lui-même fixé à un moufle 8A.We distinguish the structure of the derrick 1 placed on the ground 2. A train 3 of rods must be extended by a set 4 of preassembled rods (three rods for example) using the device of the invention. The device also makes it possible to dismantle a rod or a set of rods from the drill string. The preassembled rod assemblies such as that shown 5 are stored vertically in an area 6; the device 7 for driving and handling the rods is suspended from a hook 8 placed at the top of the derrick, the hook itself being fixed to a muffle 8A.

Par ailleurs, le dispositif d'entraînement et de manutention 7 et la chape du moufle 8A sont fixés par l'intermédiaire de vérins 9 et de bielles 100 à des chariots mobiles 10 le long de pistes verticales fixes 11. Cette liaison interdit la rotation du dispositif 7.Furthermore, the drive and handling device 7 and the yoke of the muffle 8A are fixed by means of jacks 9 and connecting rods 100 to movable carriages 10 along fixed vertical tracks 11. This connection prohibits the rotation of the device 7.

Ceci permet de déplacer le dispositif dans le sens vertical, de l'orienter selon les directions horizontales 7 et même de le stocker dans une zone de stockage 12.This makes it possible to move the device in the vertical direction, to orient it in the horizontal directions 7 and even to store it in a storage area 12.

On distingue enfin dans la figure 1 un conduit 13 d'amenée des boues de forage.Finally, in FIG. 1, a pipe 13 for supplying drilling mud is distinguished.

Le dispositif comprend un arbre creux 20, entraîné en rotation par un moteur 21, de préférence hydraulique. La boue du conduit 13 passe dans l'arbre 20.The device comprises a hollow shaft 20, driven in rotation by a motor 21, preferably hydraulic. The mud from the conduit 13 passes through the shaft 20.

Le rectangle 22 représente un réducteur de vitesse de type connu qui ne fait pas partie de l'invention et qu'il n'est pas nécessaire de décrire en détail.The rectangle 22 represents a speed reducer of known type which is not part of the invention and which it is not necessary to describe in detail.

Le dispositif de manutention comprend un vérin tournant constitué d'un piston annulaire 24, pouvant être entraîné en rotation avec l'arbre creux 20 et pouvant se déplacer en translation parallèlement à l'axe de l'arbre, et un cylindre 26 fixé à l'arbre 20.The handling device comprises a rotating cylinder constituted an annular piston 24, which can be driven in rotation with the hollow shaft 20 and which can move in translation parallel to the axis of the shaft, and a cylinder 26 fixed to the shaft 20.

Le piston annulaire possède des cannelures 25 parallèles à l'axe de l'arbre ; l'arbre possède des cannelures correspondantes. Ce double jeu de cannelures autorise ainsi les mouvements annoncés plus haut.The annular piston has grooves 25 parallel to the axis of the shaft; the tree has corresponding grooves. This double set of grooves thus allows the movements announced above.

Les mouvements de translation du piston, ainsi que les mouvements des pièces qui sont décrites plus loin, sont commandés hydrauliquement au moyen de canalisations d'huile 27 qui pénètrent dans l'ensemble mobile 24, 25, 26 par un joint tournant 28.The translational movements of the piston, as well as the movements of the parts which are described below, are controlled hydraulically by means of oil lines 27 which penetrate into the movable assembly 24, 25, 26 by a rotary joint 28.

Le piston 24 se prolonge hors du cylindre 26 par un tube tige 25A à laquelle est fixée, par l'intermédiaire d'une pièce d'adaptation 30 une vanne à boule 31, commandée hydrauliquement et fixée à un support annulaire 32. Cette vanne permet le contrôle des éruptions et permet également d'éviter que la boue ne tombe sur la tête du personnel du plancher lorsque les tiges sont otées.The piston 24 extends out of the cylinder 26 by a rod tube 25A to which is fixed, by means of an adapter part 30 a ball valve 31, hydraulically controlled and fixed to an annular support 32. This valve allows control of eruptions and also helps prevent mud from falling on the head of floor staff when the stems are removed.

Au support 32 est fixée une pièce d'extrémité 33 qui présente un filetage extérieur 33A complémentaire de celui que présente intérieurement l'extrémité renflée 4A (appelée en anglais tool-joint) de la tige de forage 4 à manutentionner.To the support 32 is fixed an end piece 33 which has an external thread 33A complementary to that which presents internally the bulged end 4A (called in English tool-joint) of the drill rod 4 to be handled.

L'ensemble mobile décrit ci-dessus est protégé par un carter fixe 35 lié à sa partie supérieure à l'ensemble moteur 21-réducteur 22 et réalisé en plusieurs éléments assemblés par des couronnes de fixation 37. Sur ce carter sont fixés deux ensembles à vérins.The mobile assembly described above is protected by a fixed casing 35 linked at its upper part to the motor 21-reduction unit 22 and produced in several elements assembled by fixing rings 37. On this casing two sets are fixed to cylinders.

Le premier ensemble comprend un groupe de vérins dont les pistons sont référencés 41A et les cylindres 41B. Chaque piston est prolongé par une pièce 41C à laquelle est fixé un crochet ou griffe 42. Les formes coniques complémentaires du crochet et du cylindre permettent au crochets de se rapprocher ou de s'éloigner de l'axe, les cylindres 41B étant fixés au carter 35 et servant d'organe de guidage aux crochets 42.The first set includes a group of cylinders whose pistons are referenced 41A and the cylinders 41B. Each piston is extended by a piece 41C to which a hook or claw 42 is fixed. The complementary conical shapes of the hook and of the cylinder allow the hooks to approach or move away from the axis, the cylinders 41B being fixed to the housing. 35 and serving as a guide member for the hooks 42.

Le mouvement simultané des crochets permet ainsi de maintenir le train de tiges par accrochage sous la partie renflée 4A du train de tiges. Il y a avantageusement quatre vérins actionnant chacun un crochet.The simultaneous movement of the hooks thus makes it possible to maintain the drill string by hooking under the bulged part 4A of the drill string. There are advantageously four jacks each actuating a hook.

Le second ensemble comprend un groupe de vérins dont les pistons sont référencés 43A et les cylindres 43B. Chaque piston est associé à une pièce 43C qui agit sur un patin 44 ; les formes coniques complémentaires des patins et des cylindres permettent un serrage énergique de l'extrémité de la tige 4, les cylindres 43B étant également fixés au carter fixe 35 et servant d'organe de guidage aux patins 44.The second set includes a group of cylinders whose pistons are referenced 43A and the cylinders 43B. Each piston is associated with a part 43C which acts on a shoe 4 4; the complementary conical shapes of the pads and of the cylinders allow energetic tightening of the end of the rod 4, the cylinders 43B also being fixed to the fixed casing 35 and serving as a guide member for the pads 44.

Avantageusement, il y a quatre vérins agissant sur quatre patins.Advantageously, there are four jacks acting on four pads.

Le fonctionnement du dispositif est le suivant, lorsqu'on désire accrocher un nouvel ensemble 4 de tiges au train 3, qui est immobilisé au niveau du plancher selon une technique connue.The operation of the device is as follows, when it is desired to hang a new set 4 of rods on the train 3, which is immobilized at floor level according to a known technique.

Grâce aux vérins 9 et chariots 10, le dispositif 7 est amené au-dessus de la zone 6 où sont stockées les tiges (ou ensembles de tiges). Le dispositif (moteur 21 arrêté) est descendu de manière à venir coiffer une tige, ce qui est facilité par le cône 48 à la base du dispositif. Lorsque l'extrémité 4A de l'ensemble est engagé, on actionne le vérin 41A - 41B pour saisir l'ensemble qui peut alors être déplacé de la zone de stockage jusqu'à la verticale du train 3.Thanks to the jacks 9 and carriages 10, the device 7 is brought above the zone 6 where the rods (or sets of rods) are stored. The device (motor 21 stopped) is lowered so as to cover a rod, which is facilitated by the cone 48 at the base of the device. When the end 4A of the assembly is engaged, the actuator 41A - 41B is actuated to grip the assembly which can then be moved from the storage area to the vertical of the train 3.

Lorsque l'extrémité inférieure 4B de l'ensemble 4 et le train 3 sont alignés on les rapproche en descendant le dispositif 7, par le moufle 8A jusqu'à ce que l'ensemble 4 vienne au contact des tiges 3. On abaisse encore l'ensemble de manière à ce que l'extrémité 4A des tiges 4 vienne en butée contre l'extrémité inférieure de la pièce 33 de telle sorte que l'extrémité renflée 4A soit en face des patins 44 et non plus supportée par les griffes 42.When the lower end 4B of the assembly 4 and the train 3 are aligned, they are brought together by lowering the device 7, by the muffle 8A until the assembly 4 comes into contact with the rods 3. The l 'together so that the end 4A of the rods 4 abuts against the lower end of the part 33 so that the bulged end 4A is opposite the pads 44 and no longer supported by the claws 42.

L'extrémité 4A est alors fortement bloqué par manoeuvre du vérin 43A - 43B ; puis le moteur est mis en route de manière à faire tourner l'ensemble mobile 20 - 24 - 32 - 33, ce qui a pour effet de visser l'extrémité 33 à l'extrémité 4A des tiges 4. Le moteur est alors arrêté et on débloque l'extrémité 4A en desserrant les patins 44 par manoeuvre en sens inverse du vérin 43A - 43B. Le moteur 21 est alors remis en marche pour visser l'extrémité inférieure 4B de l'ensemble 4 au train de tiges 3 (voir figure 1).The end 4A is then strongly blocked by actuating the jack 43A - 43B; then the engine is started so as to rotate the mobile assembly 20 - 24 - 32 - 33, which has the effect of screwing the end 33 to the end 4A of the rods 4. The engine is then stopped and the end 4A is released by loosening the pads 44 by maneuvering the cylinder 43A - 43B in the opposite direction. The motor 21 is then restarted to screw the lower end 4B of the assembly 4 to the rod train 3 (see FIG. 1).

Les vérins 41A-41B et 43A-43B libèrent alors l'ensemble de tiges 4 et le forage peut reprendre en remettant en route le moteur 21.The cylinders 41A-41B and 43A-43B then release the set of rods 4 and drilling can resume by restarting the motor 21.

L'opération de démontage des ensembles de tiges se fait de manière analogue.The dismantling operation of the sets of rods is done in a similar manner.

Le rôle du vérin 24-25 est triple :

  • - d'une part il assure les mouvements de translation verticale de faible amplitude nécessaire lorsqu'on approche (ou qu'on éloigne) l'extrémité 33 des tiges 4 ou l'ensemble de tige 4 du train de tiges 3
  • - d'autre part, il permet de compenser la longueur des filetages aux moments des vissages ou dévissages.
  • - associé à une capacité hydraulique il permet, au cours du forage, d'amortir certaines vibrations pouvant remonter du train de tiges.
The role of cylinder 24-25 is threefold:
  • on the one hand, it ensures the vertical translational movements of small amplitude necessary when approaching (or moving away from) the end 33 of the rods 4 or the rod assembly 4 of the rod train 3
  • - on the other hand, it compensates for the length of the threads at the times of screwing or unscrewing.
  • - associated with hydraulic capacity, it makes it possible, during drilling, to dampen certain vibrations that can rise from the drill string.

Le dispositif de l'invention présente de nombreux avantages :

  • - il est suffisamment compact pour remplacer les dispositifs existant sans surélévation du derrick,
  • - il peut être écarté et mis dans une position non gênante, en cas de panne et remplacé par un système de manutention classique,
  • - il permet des compensations de filetage et des amortissements de vibration,
  • - il permet d'obturer aisément le conduit de boues lorsque les tiges sont otées,
  • - il permet une manutention rapide et absolument sans danger des tiges de forage.
The device of the invention has many advantages:
  • - it is compact enough to replace existing devices without raising the derrick,
  • - it can be moved aside and put in a non-annoying position, in the event of a breakdown and replaced by a conventional handling system,
  • - it allows compensation for threading and vibration damping,
  • - it allows to easily close the sludge pipe when the rods are removed,
