Definitions

  • This invention relates to the freeing of stuck or jammed tubulars or other objects downhole and more particularly, to a downhole coiled tubing recovery apparatus and method designed to utilize a resonant frequency oscillator in combination with a specially designed coiled tubing bail for directing coiled tubing directly from a tubing reel through an injector head and to and from the well responsive to raising and lowering of the oscillator and the tubing bail. Freeing of the tubulars or objects is accomplished by typically resonance vibration of the bail and coiled tubing by operation of the oscillator.
  • Oil field tubulars such as well liners, casing, tubing and drill pipe stuck in a well bore due to various downhole conditions have been one of the principal sources of problems for oil operators and have expanded the business activity of fishing service companies in this century. During this period of time, many new and innovative tools and procedures have been developed to improve the success and efficiency of fishing operations. Apparatus such as electric line free point tools, string shot assisted backoff, downhole jarring tools, hydraulic-actuated tools of various types and various other tools and equipment have been developed for the purpose of freeing stuck or jammed tubulars downhole in a well.
  • vibration and resonant vibration in particular, as a means of freeing stuck tubulars from a well bore has the potential to be immediately effective and thus greatly and drastically reduce the cost involved in tubular recovery operations.
  • Resonance occurs in vibration when the frequency of the excitation force is equal to the natural frequency of the system. When this happens, the amplitude (or stroke) of vibration will increase without bound and is governed only by the degree of damping present in the system.
  • a resonant vibrating system will store a significant quantity of energy, much like a flywheel.
  • the ratio of the energy stored to the energy dissipated per cycle is referred to as the systems "Q" .
  • Q The ratio of the energy stored to the energy dissipated per cycle.
  • a high energy level allows the system to transfer energy to a given load at an increased rate, much like an increase in voltage will allow a flashlight to burn brighter with a given bulb. Only resonant systems will achieve this energy buildup and exhibit the corresponding efficient energy transmission characteristics which assure large energy delivery and corresponding force application to a stuck region of pipe.
  • a string of pipe will transmit power over its length to a load at the opposite end with the only loss being that necessary to overcome resistance in the form of damping or friction.
  • power is transmitted in the same manner as the drilling process transmits rotary power to a bit, the difference being that the motion is axial translation instead of rotation.
  • the load accepts the transmitted power as a large force acting through a small distance.
  • Resonant vibration of pipe can deliver substantially higher sustained energy levels to a stuck tubular than any conventional method, including jarring. This achievement is due to the elimination of the need to accelerate or physically move the mass of the pipe string. Under resonant conditions, the power is applied to a vibrating string of pipe in phase with the natural movement of the pipe string.
  • vibrational energy received at the stuck area works to effect the release of a stuck member through the application of large percussive forces, fluidization of granular material, dilation and contraction of the pipe body and a reduction of well bore friction or hole drag.
  • Bodine, Jr. details a sonic pile driver which utilizes a mechanical Oscillator and a pile coupling device for coupling the oscillator body to a pile and applying vibrations of the pile to drive the pile into the ground.
  • the device includes a number of rotatable, power-driven eccentrics which are connected to an elongated member such as a drill pipe that is stuck in an oil well bore hole and to a resiliently-movable support suspended from the traveling block of an oil derrick.
  • a "Device For Facilitating the Release of Stuck Drill Collars" is detailed in U.S. Patent No. 4,576,229, dated March 18, 1986, to Robert L. Brown.
  • the device includes a first member mounted with the drill pipe disposed in a first position and a second member concentrically mounted with a drill collar or drill pipes in a second position below the first position. Rotation of. the drill string from the surface causes a camming action and vibration in a specified operative position of the device, which helps to free stuck portions of the drill pipe.
  • U.S. Patent No. 4,788,467 dated November 29, 1988, to E.D.
  • E.P. Patent 0 395 167 detailes an apparatus and a method of drilling using a coiled tubing. There is no suggestion, however, of any means or method for handling continuous pipe such as coiled tubing, in a vibrational or any other application. It is thus an object of this invention to provide an apparatus and method for working coiled tubing in a stuck pipe or other downhole stuck equipment situation, wherein the coil may be raised and lowered in the well bore by a support structure that includes a lifting and lowering apparatus. Such movement of the coil is accomplished with substantially no bending of the coil string.
  • Another object of this invention to provide a new and improved downhole coiled tubing recovery apparatus and method for releasing and recovering coiled tubing and other objects stuck or jammed downhole in a well.
  • Yet another object of this invention is to provide a new and improved downhole coiled tubing recovery apparatus and method which operates utilizing resonant vibration in combination with a specially designed coiled tubing bail to facilitate the release of stuck or jammed coiled tubing from a well.
  • Another object of the invention is to provide a new and improved coiled tubing recovery apparatus that may be applied to a continuous length of coiled tubing without cutting the tubing, and operated to vibrate the coiled tubing and remove the coiled tubing and other objects from a stuck or jammed position in the well.
  • Another object of this invention is to provide a downhole coiled tubing recovery apparatus and method, which apparatus is characterized by an oscillator suspended from a rig or other support structure and a coiled tubing bail attached to the oscillator for receiving a length of coiled tubing extending from a coiled tubing reel and directing the coiled tubing through an injector head into the well, such that the oscillator can be operated to vibrate the coiled tubing, typically at a resonant frequency, and remove the coiled tubing from a stuck or jammed condition in the well.
  • a specially designed coiled tubing bail is suspended directly from a rig structure or from an oscillator that is further suspended from the travelling block or other supporting structural element of an oil derrick or rig, the coiled tubing is directed from a reel through a set of rod clamps in the coiled tubing bail and through an injector head, into the well bore.
  • the coiled tubing bail can be lifted and/or the oscillator can be lifted and operated to apply resonant vibration through the coiled tubing bail and the coiled tubing to loosen the coiled tubing in the well hole.
  • two sets of the plate bolts 7 extend through the respective bail legs 5, while another set of the plate bolts 7 extend in spaced-apart relationship with respect to each other near the center of the tubing plate 6, for accommodating the downhole segment 29 of a length of coiled tubing 28, as illustrated in FIGURES 1 and 2.
