Definitions

  • the pig includes a grouping of a plurality of individual piglets and at least one flexible member interconnecting adjacent piglets.
  • the fiber includes a length of optic fiber and at least one flexible pipe pig attached thereto.
  • the Pig includes a grouping of a plurality of piglets. The pig is attached to the optic fiber.
  • the method includes attaching a flexible pipe pig, having a grouping of a plurality of piglets, to the optic fiber.
  • the method includes introducing a fluid into a conduit, the fluid causing movement of the optic fiber through the conduit by causing a lower pressure environment ahead of a flexible pipe pig, having a grouping of a plurality of piglets, of the flexible pipe pig through the conduit.
  • a pipe pig including a body having a non-deflected outside dimension in a single cross-section of the body, which represents a largest transaxial cross-section of the body, the cross-section of the body being smaller than an inside dimension of a conduit through which the pipe pig is intended to be run.

  • Figure 2 is a schematic illustration of a flexible pipe pig disposed at the end of an optic fiber wherein the pipe pig illustrates flexibility in its form;
  • Figure 3 is a schematic illustration of a flexible pipe pig having individual piglets of varying external dimension
  • Figure 4 is a schematic illustration of a single-part pipe pig.
  • Figure 5 is a schematic illustration of a conical or frustoconical pig.
  • a flexible pipe pig not having the operational restrictions of pipe pigs of the prior art is illustrated generally at 10 and comprises a grouping of a plurality of piglets.
  • three individual piglets 12 (it will be understood that more or fewer piglets may be employed without departing from the scope of this disclosure) are connected to one another by at least one flexible member 14, the member(s) being sufficiently strong and durable to survive the environment in which it is intended to be used.
  • the member(s) may comprise plastic, metal, glass or even may comprise the optic fiber itself.
  • Each piglet comprises a material capable of withstanding the same environment.
  • the environment envisioned is the downhole environment of a hydrocarbon installation, but other environments are also contemplated to become home to the flexible pipe pig and are therefore to be considered in selecting a material.
  • materials contemplated, and by no means an exhaustive list, include metal, plastic, rubber, ceramic, etc.
  • each piglet may be smaller while maintaining the same driving force.
  • Each piglet creates some of the driving force desired by creating a low-pressure zone downstream of the piglet. While a greater lower (more relatively negative) pressure is created with a smaller difference between the outside dimension of the piglet and the inside dimension of the conduit, the greater is the change that such piglet will get stuck.
  • the size may be reduced and the total driving force maintained while the tendency to get stuck is also reduced.
  • each piglet 12 is spaced from an adjacent piglet by an appropriate distance to accomplish the goal of flexibility and movement and in one embodiment, by about 1 A inch to about 5 inches in order to provide for maximum flexibility while still providing optimum optic fiber pulling capability.
  • each piglet 12 is generally spherically formed having a diameter of less than an inside diameter of a fiber optic conduit 16 through which the pipe pig 10 and connected optic fiber 18 (or fibers) is (are) intended to travel.
  • the degree to which the spherical piglet is smaller in diameter than the inside dimension (ID) 20 of the fiber optic conduit 16 is in the range of about 70 % to about 95% as such range causes fluid (liquid or gas; this structure enables the use of very low viscosity fluid.), illustrated by arrows 22, pumped through the conduit 16 to move around the outside dimension of each piglet 12 in such a manner as to cause a pressure drop in fluid pressure ahead of the piglet relative to the higher pressure behind the piglet to move the piglet through the conduit.
  • the pressure drop functions as a resultant force to move the piglet, and thereby anything connected thereto, toward the lower pressure.
  • the size is also configured to create a feature (e.g.
  • the degree of positive displacement force versus the low-pressure resultant force is a function of the size of the piglet relative to the ID of the conduit.
  • the size provides a synergistic relationship between low-pressure-based movement and positive displacement-based movement.
  • Piglets in different embodiments may be of the same shape in a flexible pig, individually different shaped piglets in a pig, and different shapes among different pigs while individual pigs have similarly shaped piglets. It should be appreciated, that the selection of geometry of each piglet will likely affect the ability of the flexible pig 10 to move through bends in the optic fiber conduit 16.
  • An illustration of the flexible pig 10 moving through the bend in a conduit 16a is provided in Figure 2. It will be easily appreciated by one of ordinary skill in the art that a prior art pipe pig could not have moved through this bent section of conduit 16a illustrated in Figure 2.
  • the spherical piglets 12 of figure 1 in conjunction with flexible members 14, for example, facilitate easy translation of each piglet relative to each other piglet to enable movement through the bent section. It should further be noted that the spherical shapes and semispherical shapes facilitate movement through tighter bend radiuses than other shapes simply because of the ability of the shape to pivot on its own center point without representing an increased radius regardless of bend angle.
  • the piglets may be attached to members 14, or to the optic fiber 18 itself, by means of glue, fusing, molding, etc.
  • the attachment must be strong enough to allow the flexible pipe pig to pull the optic fiber through the conduit.
  • more than one individual flexible pipe pig is utilized along the length of the optic fiber to be installed into an extended conduit. This embodiment will appear as does the figure 1 embodiment but the flexible pipe pig will repeat over a distance much too great to be illustrated directly.
  • Each flexible pig will be disposed at a selected length interval along the optic fiber of, for example, 1,000 feet. It will be understood that greater or lesser intervals are contemplated and that both equal length intervals and unequal length intervals are contemplated.
  • individual piglets may be employed upon the fiber or fibers to be installed in a conduit over an extended length of the fiber or even over the entire length of the fiber at selected length intervals between each piglet and with a complete flexible pig at least somewhere along the line being installed.
  • the appearance of such will be as is figure 1 but the piglets will simply continue to occur along the optic fiber at some selected interval. This may be beneficial in some instances in order to distribute the load placed upon the fiber over a greater length of the fiber.
  • the external dimensions of individual piglets in a flexible pipe pig will vary, referring to figure 3.
  • the figure illustrates a flexible pipe pig with a grouping of three piglets 30, 32, and 34, each progressively growing in outside dimension as they approach the lead piglet (piglet 34), which is the largest of the grouping.
  • the growing size of piglets facilitates a more laminar flow of fluid around the pig itself such that lower pressure areas behind the pig are avoided. Turbulence is likewise minimized. As such the resultant motive force imparted on the pipe pig is greater to move the pig in the desired direction.
  • the fluid flow is increasingly choked off until it reaches the lead piglet and creates the desired lower pressure ahead of the pig.
  • the entire pig has greater flexibility through bends in the conduit.
  • a vacuum source is connected to a return line of the conduit.
  • Such vacuum source will create a lower pressure environment ahead of the first piglet in a flexible pig at the leading end of the line being installed.
  • the vacuum source may be employed alone, with no fluid pressure from behind the flexible pig or may be employed in conjunction with the fluid discussed above in this disclosure.
  • the shape of such pig in one iteration is ellipsoidal which is defined as "a surface all plane sections of which are ellipses or circles.” Clearly, this term includes spherical objects, which is intended herein. Moreover, in another iteration, the shape may be that of a pair of cones or of frustocones (see Figure 5) axially joined at their respective bases.
