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
  • 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
  • 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.
  • the pipe diameter will expand and contract in unison with the applied tensile and compressive waves. This means that for alternate moments during a vibration cycle the pipe may actually be physically free of its bond.
  • fluidization is used to describe the action of granular particles when excited by a vibrational source of proper frequency. Under this condition, granular material is transformed into a fluidic state that offers little resistance to movement of body through the media. In effect, it takes some of the characteristics and properties of a liquid. Accordingly, skin friction, that force that confines a stuck tubular, is reduced to a fraction of its normal value due to the effect of vibration because of alternate tensile and compressive forces applied to a pipe and to the fluidization of granular particles packed around the pipe.
  • -4- Resonant vibration systems for use in oilfield tubular extraction applications consist of three basic components: a mechanical oscillator with a suspension device for isolating the rig or Support structure, a work string for transmitting vibrational energy, and the stuck tubular or fish to be recovered.
  • the oscillator generates an axial sinusoidal force that can be tuned to a given frequency within a specified operating range.
  • the force generated by the oscillator acts on the work string to create axial vibration of the string.
  • energy developed at the oscillator is efficiently transmitted to the stuck member with the only losses being those attributed to frictional resistance.
  • the effect of the system reactance is completely eliminated because mass inductance is equal to spring campacitance at the resonant frequency.
  • the total resonant system must be designed so that the components act in concert with one another, thus providing an efficient and effective extraction system.
  • the principal of resonant axial vibration of pipe can be applied to coiled tubing without using the gooseneck equipment. Additionally, it has been found that the coiled tubing does not necessarily need to be cut when used with the downhole coiled tubing recovery apparatus of this invention, thus saving the cost of a reel of tubing, as well as maintaining and enabling good well control, along with the facility for circulating fluids into and from the well.
