Abstract

The present invention refers to an equipment for the installation and removal of plugs from submarine well, which comprises a hydraulic cylinder (1) which is coupled to specific tools (9) for installation and removal of plugs (2) in columns suspenders (3) or WCTs (4).

Description

    Field of the Invention
  • The present invention refers to an equipment for the installation and removal of plugs from submarine wells. More specifically, the present invention refers to a hydraulic equipment for the installation and removal of plugs column suspenders or wet Christmas trees.
    • History of the Invention
  • When the submarine well is complete or suspended, it is necessary to obstruct the passage of piping and, optionally, the ring passage in the well to provide barriers against the well pressure. In order to prepare a well for production, it is necessary the removal of plugs from the piping and/or from the suspension barriers, allowing the well fluid to flow inside the production flow line.
  • The removal of plug from a well under pressure is performed by having complete control over the well. Usually, plugs are removed through lifters (riser) and BOP systems to ensure the necessary complete control. This operation, often, needs an intervention vessel or a drilling platform with the largest dimensions, which represents very high cost for its realization. Thus, there is a need for more economical methods of installation and removal of plug-type barriers in wet Christmas tree holes or tubing hanger, without relying on intervention vessels or drilling platforms which, as said, are of high operational cost.
  • Another system traditionally used for the installation or removal of plugs from submarine wells is the tool system descent by wire/threads. However, this system has as the main disadvantage the fact of requiring lubricating equipment to isolate pressure from inside the well. This equipment is expensive and requires an operation with some difficulty.
  • The document US 6.719.059 , for example, describes a tool for recovering and installing plugs in a submarine well having a production tree, a tubing hanger, a passage extending vertically through the tubing hanger and tree and a plug located inside a plug profile in the passage inside of the tubing hanger. The device for plug retrieval has a housing and a connector which is lowered on an elevation line to the upper end of the tree. An axially extendable stem in the housing is driven by a mechanism into the production passage of the tubing hanger. A stem-mounted recovery element attaches to the plug and pulls it up while the stem is being moved upwards. The connector, the drive mechanism and the recovery element are energized by a ROV.
  • The document CA2564698 refers to an apparatus to install a plug, or to recover a plug from a horizontal Christmas tree. The apparatus comprises a housing with a through bore adapted to be releasable connected by a first end to a horizontal Christmas tree. Said housing includes at least one axially movable member which also includes at least one radially movable element and an extended tool within the through bore of said housing by an elongated support and adapted to be releasable connected to the plug. It further has a tool having a shaped outer surface portion for releasable engaging an engaging surface, or at least one radially movable element by means of which, in operation, Engagement of the at least one radially movable element with the outer surface portion of the tool allows the plug, connected to said tool, to be installed in the horizontal Christmas tree or recovered from it by axial movement of the at least one axially movable member.
  • The document US8.672.037 describes a method for removing a plug that includes a step of deploying an intervention packet Which has at least one valve, cutting elements and tube seals, and a lubricating apparatus in a submarine environment.
    • Objects of the Invention
  • The present invention aims to provide an equipment for installing and removing the plugs from the submarine wells that can Advantageously replace those of the prior art, providing technical, operational and economic gains for this operation.
  • Thus, the present invention provides an equipment coupled with specific tools for installation and removal of plugs on column suspenders or wet Christmas trees (WCTs), instead of using lifters and BOP system, or the tool system descent by wire/thread traditionally used by these operations.
    • Brief Description of the Figures
  • The present invention will be described below with reference to the attached figures, which represent in a schematic and non-limiting way of its scope:
    • Figure 1 - illustrates the installation or removal of plugs by the equipment in column suspenders and wet Christmas tree, according to the invention; and
    • Figure 2 - illustrates the main components of the equipment of the invention.
    Detailed Description of the Invention:
  • According to figure 1, it is noted that the equipment for the installation and removal of plugs from submarine wells comprises a hydraulic cylinder (1), is coupled to the specific tools (9) for the installation and removal of plugs (2) in column suspenders (3) or WCTs (4).
  • In figure 2, it is noted that the hydraulic cylinder (1) will remain anchored by means of a locking mechanism (5) to a tool (6) which will be part of the installation or removal assembly of the WCT of the oil well. Said hydraulic cylinder (1) can have multiple seals (7) isolating the interior of the well from the external environment, and can be, in contingency, removed with or without the plug and plug tools from the place where it is anchored. For this, said hydraulic cylinder (1) has in its upper part a compatible profile with tools for recovering (8).
