Definitions

  • the invention relates to an anchor mechanism for a tool which is temporarily to be fixedly positioned in a well. More particularly, the invention relates to an anchor mechanism which prevents sand and other material from entering the anchor mechanism while it is being used, and which allows the wedges of the anchor mechanism to be completely retracted when the anchor mechanism is being disengaged, even if sand and other material have entered the anchor mechanism.
  • Bridge plugs are installed in wells for hydrocarbon production that are under pressure.
  • the purpose may be to seal a portion of the well, be a barrier that prevents the flow of hydrocarbons, or prevent the flow of gas, oil or water between zones downhole.
  • Such a plug includes an anchor mechanism and a packer element, and the plug is normally set by means of an external setting tool which has been lowered into the well.
  • the setting tool generates an axial force which is converted into a radial expansion of the anchor mechanism and the packer element so that the anchor mechanism and the packer element are pressing against the inner wall of the pipe.
  • the setting tool is disconnected from the plug and pulled out of the well.
  • the plug remains fixed to the casing or the pipe downhole.
  • the anchor mechanism holds the plug in place by frictional force between the wedges, the so-called slips, of the anchor mechanism and the inner pipe wall.
  • the slips are forced out against the inside of the pipe wall so that the entire plug is held in position in the axial direction.
  • a retrievable plug is normally retrieved from the well by lowering a pulling tool into the well.
  • the pulling tool is attached to the so-called fishing neck of the plug; the plug is disengaged by the packer element and the slips of the anchor mechanism being retracted away from the inner wall of the pipe or the casing, and then the plug is pulled out of the well.
  • It is a known problem within the industry that there is a risk of retrievable plugs sticking when the plug is to be pulled out of the well, especially after periods during which the plug has been a barrier between zones of different pressures in the well.
  • One problem is connected with sand and particles entering essential parts of the anchor mechanism and preventing movement in the mechanical systems. The anchor mechanism thereby does not function as intended when the plug is to be pulled.
  • anchor mechanisms include slips that can be moved in two directions, in and out, in the radial direction of the plug. Such slips are much used to ensure that the correct clamping force against the inner wall of the pipe or casing is achieved. Many designs are based on the slips being provided, at their end portions, with inclined faces that are brought into contact with inclined faces on cooperating upper and lower slip cones, as shown in the patent document US 4,359,090, for example. It is a problem with such slips that they must be held in a central position between the two cooperating slip cones. The slips must be held in position so that they can freely be moved radially.
  • 4,359,090 discloses an anchor mechanism which is open towards its surroundings so that particles may enter the mechanism and prevent the slips from being fully retracted in the radial direction when the plug is to be disengaged and pulled.
  • the invention has for its object to remedy or reduce at least one of the drawbacks of the prior art or at least provide a useful alternative to the prior art.
  • the invention discloses an anchor mechanism for retrievable plugs for use in oil- producing and gas-producing petroleum wells.
  • the anchor mechanism is arranged to prevent sand and other material from entering the mechanism. Sand and other material may prevent the slips of the anchor mechanism from being fully retracted when the plug is to be disengaged from the well wall and pulled out of the well.
  • the anchor mechanism is arranged to be used in wells at high pressures, for example of 10,000 psi or 690 bars, and high temperatures, for example up to 200 °C, and in wells with high concentrations of H 2 S and C0 2 , for example 40 % H 2 S and 20 % C0 2 .
  • the choice of materials for forming such an anchor mechanism and such a plug must have regard to such conditions.
  • the invention relates to an anchor mechanism for use in a well, the anchor mechanism including a housing with a plurality of openings; the openings being evenly distributed along the circumference of the housing and each opening being arranged to narrowly house a radially movably slip; the slip including first and second end portions, a gripping side facing a well wall, the gripping side being provided with a plurality of teeth, an underside facing the opposite direction, two side faces extending from the gripping side to the underside and to two end faces; the slip being provided, in its first and second end portions, with first and second inclined faces substantially sloping from the end faces towards the middle portion of the slip on the underside; the slip being provided, on its end faces, with laterally projecting tongues which have a longitudinal direction parallel to the inclined faces; the slip being provided, on its two side faces, with guide portions exhibiting a longitudinal direction perpendicular to the longitudinal portion of the slip and the guide portion complementarily fitting an inward-facing guide in the housing; the anchor mechanism is further
  • the slip On its underside, the slip may be provided with a notch.
  • the slip may be moved radially inwards until the teeth of the slip are flush with the surface of the housing, without the movement being obstructed by foreign bodies under the slip.
  • the tongue of the slip may be formed with a bevel on the side facing the inclined face of the slip cone. This has the advantage of the tongue not being subjected to shear forces directed radially, which could cause the tongue to break at the side face of the slip.
  • the housing halves may be provided with flanges projecting inwards, and the flanges may be stepped in a portion facing the opening, so that, after having been connected to each other, the housing halves may exhibit an inward-facing guide for the guide portion of the slip.
  • Connecting the housing halves to each other at the flanges projecting inwards may be done with a bolt connection, a screw connection, by gluing or by welding.
  • the inward-facing flanges may have the advantage of increasing the strength of the housing wall and of the guide getting great strength in the axial direction and sideways in the circumferential direction.
  • the guide that may be formed by the flanges may simplify the assembling of the anchor mechanism by the guide not being formed as a separate component that has to be fixed separately to the wall of the housing. This may also reduce the number of components in the anchor mechanism.
  • the guide may be a groove which complementarily fits a projecting ear on the side face of the slip so that the ear may form the guide portion of the slip.
  • the guide may be a projecting lip which fits complementarily in a groove in the side face of the slip, so that the groove forms the guide portion of the slip.
  • an inward-facing guide is meant that the guiding direction is from the surface of the housing and in towards a central portion of the anchor mechanism.
  • the anchor mechanism may further include an inner sleeve positioned in the through openings of the slip cones; wherein the inner sleeve may be provided with an outer threaded portion on one end portion of the sleeve; and the sleeve may be threadedly fixed to an internal threaded portion of the first end portion of the first slip cone; and, on its inside, the sleeve may further be provided with a circular shoulder which may be arranged to rest against an external, circumferential shoulder on a mandrel which may extend internally through the sleeve.
  • This has the advantage of the sleeve being usable for adjusting the axial distance between the slip cones and keeping it constant before the anchor mechanism is activated.
