Definitions

  • a device of a tong or roughneck is usually used in running a string of drill pipe or other pipe into or out of a well typically called “tripping”.
  • the roughneck is usually consist of a torque wrench having a lower wrench and top wrench rotating relatively each other, and a spinner wrench used for connecting and disconnecting the various drilling components, such as drill pipes and drill collars.
  • the upper wrench holds the upper tool joint called “pin”
  • the lower wrench holds lower tool joint called “box”.
  • the spinner rollers are typically only engaging with stem of the drill string not with the tool joints.
  • the iron roughnecks of the prior art cannot be used for connecting and disconnecting some types of drill stem components.
  • spiral collars have external stabilizers along the stem which can be damaged by the rollers of a spinning wrench.
  • Other components have other variations in surface and shape which make them unsuitable for contact with spinning rollers along their stems.
  • U.S. Pat No. 6,776,070 shows the torque wrench of a pair of integrated the spinner rollers withjaws formed in the confined recess area between the two sets of side rollers.
  • the clamping jaws are formed in a very confined recess area which limits its clamping capacity and unable to provide the required torque capacity for different sizes of tool joints.
  • it is unable to centralize the tool joint while closing the spinners because the torque wrench cannot maintain the same position while engaging the tool joint without repositioning the entire torque wrench itself.
  • Another problem with U.S. Pat No. 6,776,070 is that the spinner rollers are limited in size it cannot provide the spinning torque big enough to tight the tool joint, therefore the top wrench needs to make repeated back and forward rotation cycles to tight the tool joint connection of drill string, which causes prolong tipping time in field.
  • the object of the present invention is to provide a plurality of modules of integrating spinner rollers with clanping dies into the torque wrench to connect or disconnect all types of drill strings by spinning and clanping directly on the tool joints rather than on stem of the drill strings, and all sizes of drill strings with enough industry required torque capacity.
  • the preferred embodiment is with triple modules though double modules are also a simplified embodiment
  • Another object of the present invention is to eliminate the separate spinner wrench overhanging above the torque wrench and to make the tripping operation simpler, faster and more efficient.
  • the further object of the present invention is to centralize the drill string by moving the modules in substantially straight line simultaneously towards to the center of the drill string without repositioning the entire torque wrench itself.
  • Another further object of this invention is to provide adequate spinning torque so the spinner rollers can quickly spin the tool joint connection tight enough such that subsequently the torque wrench can just make a single rotation cycle to make the connection with required torque, thus to drastically saving the tripping time.
  • the object of this invention is to provide a means of actuating the movement of spinner rollers and the clamping dies in an orderly manner such that the rollers and dies can engage the same tool joint but at the sequential order as required.
  • the object of this invention is to provide a stand-alone spinning and torque device injunction to other existing backup device to hold the box on the rig to connect or disconnect drill string or other threaded equipment SUMMARY OF THE INVENTION
  • This invention introduces a torque wrench that has a plurality of modules of integrating spinners and clamping dies into an upper wrench able to directly clamp on the upper tool joint area of a drill string or other threaded equipment.
  • two spinner roller are used with common driving shaft, located both on the top and the bottom in between there is a clamping die or dies and die holder which can move in or out relatively to the spinner rollers such that the spinner rollers and dies can engage with the same upper tool joint but independently in sequence.
  • This invention eliminates the extra spinner unit typically suspending above the upper wrench, simplifies the tripping operation, and provides the ample clamping power on all sizes of tool joints inpossible in the prior arts.
  • the vertical arrangement of sandwiching the clanping die and the die holder in between the top and bottom rollers along the vertical direction of the drilling string makes it possible to have the clanping die holder designed strong enough to clamp on any sizes and types of tool joints widely used in the field operation.
  • the integrated spinners and clanping dies provides the self-centralizing capability to keep the tool joint in the well center position.
  • This invention also has a lower wrench with multiple clamping jaws which are used to hold the lower tool joint of the drill typically called the “box” during the tripping operation.
  • the lower wrench is stationary without rotational movement
  • the upper wrench is supported by the lower wrench and is able to rotate relative to the lower wrench about the axis of the drilling string.
  • the lower wrench is supported by other means which allows the lower and upper wrenches together rising up and down along the drilling sting to locate the tool joint.
  • the lower wrench is preferred it is not necessary to have it to connect or disconnect the drill string or other threaded equipment since other means such as the drill floor slip and other backup tong or clamping devices can also hold the lower tool joint of the drill string or other threaded equipment

Abstract

La présente invention porte sur une clé dynamométrique 1 qui a une pluralité de modules 25 d'intégration de rouleaux d'entraînement et de matrices de serrage dans une clé supérieure 3 apte à serrer directement la zone de raccord d'outil d'un train de tiges de forage tubulaire ou d'un autre équipement fileté. Le rouleau d'entraînement a un arbre d'entraînement dans lequel se trouve une matrice de serrage qui peut se déplacer dans le rouleau d'entraînement ou hors de ce dernier de telle sorte que le rouleau et la matrice peuvent venir en prise avec le même raccord d'outil mais indépendamment en séquence. La présente invention élimine l'unité d'entraînement supplémentaire généralement suspendue au-dessus de la clé supérieure 3, simplifie l'opération de déclenchement, et fournit la grande puissance de serrage sur toutes les tailles de raccords d'outil, ce qui était impossibles dans l'état antérieur de la technique. En plus d'une pluralité de modules 25 d'entraînements intégrés et de matrices de serrage intégrés, le support de matrice de serrage est conçu suffisamment fort pour se serrer sur n'importe quelle taille de raccords d'outil requis dans l'opération sur le terrain. En outre, une pluralité de modules 25 d'entraînements et de matrices de serrage intégrés assurent la capacité d'auto-centrage pour maintenir le raccord d'outil dans la position centrale du puits. La présente invention a également une clé inférieure 7 avec de multiples matrices de serrage qui sont utilisées pour maintenir le raccord d'outil du foret typiquement appelé "boîte" pendant l'opération de déclenchement. La clé inférieure est fixe sans mouvement de rotation. La clé supérieure 3 est supportée par la clé inférieure 7 et est rotative par rapport à la clé inférieure autour de l'axe de la colonne de forage. La clé inférieure 7 est supportée par d'autres moyens 5 & 6, ce qui permet à la clé inférieure et supérieure de monter et descendre ensemble le long de la colonne de forage pour localiser le raccord d'outil.
