Description

FIELD OF THE INVENTION

The present invention relates to the field of spatial frame structures for surface fountain reinforcement, in particular to a frame system and a method for its operation.

BACKGROUND

From the prior art, various frames are known both for surface fountain fittings and for uninhabited underwater vehicles. In particular, one of the analogues is the source CN 206230551 U, publ. 06/09/2017, in which the frame for an uninhabited underwater vehicle is disclosed. In addition, from the source RU 2505664, publ. It is known to use an auxiliary frame, in which a fountain armature is installed, connect and fasten the frame. Another relevant source is patent US 9702220 B2, publ. 07/11/2017, which discloses the use of a support frame for fountain fittings. The frame according to US 9702220 B2 includes an eyelet for receiving a crane device. In the source US 9738199 B2, publ. 08/22/2017, disclosed the use of a transport frame for a blowout preventer. A known transport frame may include a rear and a platform extending perpendicular to the rear of the transport frame. The shipping frame may be in a position where the rear is vertical and the platform is horizontal. This position can be used, for example, when mounting or storing a blowout preventer. When transporting the preventer by truck, carriage or boat, the frame is positioned so that the platform as a whole is placed vertically, and the rear of the transport frame is placed horizontally. The process of transporting the preventer on the transport frame can be called "towing by semi-loading." The transport frame includes one or more beams connected to the platform, for example, a bolted or welded connection. The beams of the transport frame can be joined together at the end opposite the platform to the lifting point. The lifting position can be arranged so that the frame can be lifted, for example, using a winch or a crane.

Thus, from the source US 9738199 a transportation frame is known having the following common features with the proposed technical solution: it is used in two positions: transport and working (for storage); the ability to lift and transport the frame using a winch or crane.

Distinctive features of the proposed technical solution from the well-known according to US 9738199 are the following: the equipment installed in the protective frame is immersed on the proposed transportation frame, while the equipment is installed on the known transportation frame without a protective frame; in the proposed technical solution, the transfer of the transport frame with the protective frame installed on it with the surface fountain reinforcement from one position to another is carried out by means of eyes located on the protective frame or by means of eyes located on the transport frame.

The surface fountain reinforcement is an object having a displaced center of gravity, that is, an oversized load. Transportation of such goods is always difficult.

SUMMARY OF THE INVENTION

The technical result achieved in the proposed technical solution is to ensure the transfer of the proposed frame system from horizontal to vertical when installed in the protective frame of the fountain, having a shifted center of gravity. The technical result is achieved due to the fact that the protective frame, the protective frame is made with the possibility of installing surface-mounted fountain fittings in it by attaching the surface-mounted fountain fittings in places of attachment, and also due to the fact that the protective frame with the mounted surface-mounted fountain fittings can be installed on a transport frame by means of fixation.

DETAILED DESCRIPTION OF THE INVENTION

The frame system 1 for the surface fountain reinforcement 2 includes a protective frame 3 and a transport frame 4. In FIG. 1, a general view of the frame system 1 is illustrated, on which it is seen that the surface fountain reinforcement 2 is installed in the protective frame 3, and the protective frame 3 is installed on the transport frame 4.

The protective frame 3 for the surface fountain 2 can be used to operate the surface fountain, which is not stationary, but is floating or mobile, in other words it is moved from one well to another for completion and repair of wells. The design of the protective frame 3 allows you to securely mount the surface of the Christmas tree 2 to the transport frame 4. However, the protective frame 3 can also be attached to any suitable vehicle. The fastening means of the protective frame 3 to the transport frame 4 may be any suitable fastening means, in particular a bolt or hairpin connection.

The protective frame 3 is a spatial structure including a first frame module 5 and a second frame module 6, as shown in FIG. and FIG. 3. The first module 5 and the second module 6 are generally identical in symmetry and can only differ by the location of the platforms 7 for valves 8 of the surface water valves 2 and by the location of the indicators 9 for visual control of the location of the valves, since the location of the platforms 7 depends on the location of the pipelines on the fountain fixture.

Indicators 9 are installed near each gate of the surface fountain reinforcement 2 to determine its position, that is, the "open" position and the "closed" position, by the drilling rig operator during visual inspection. Indicators 9 can be painted in different colors and have a different shape to allow operators to see the position of the valves from different positions of the operator, for example, when the operator is under a protective frame with surface fountain fittings.

Each of the frame modules 5, 6 contains beams 10 of essentially rectangular cross-section, connected by a welded joint to form a parallelepiped-shaped structure, two of whose sides are formed by a grid, respectively, the first grid 11 and the second grid 12, connected to the beams 10 by a bolt connection 13. The first grid 11 overlaps the side of the protective frame 3 through which the valves 8 of the fountain fittings 2 pass, and the second grid 12 overlaps that side of the protective frame through which the nozzle 14 for the elevator passes. In the first grid 11, platforms 7 are made for valves of fountain valves 2.

The protective frame 3 is provided with several types of eyes, in particular, in the two extreme vertices of each frame module 5, 6, the first transportation eyes 15 with one hole are located on the beams, between which the multi-position eyes 16 with many holes are located on the beams 10. In addition, other additional transportation eyes with one hole can be located on the beams 10.

Both types of lugs allow lifting operations with the surface fountain fittings located in the protective frame 3 mounted on the transport frame 4, both in the working horizontal position and in the transport vertical position, and multi-position lugs additionally provide the possibility of lifting operations during operation of the frame system, containing surface fountain reinforcement 2 having a displaced center of gravity like any oversized cargo. The working horizontal position of the frame 4 and the transporting vertical position of the frame 4 are different from each other and are illustrated in FIG. 5-7.

Lugs are also used to sling 1-frame system cables with installed surface-mounted fountain fittings, i.e. surface-mounted fountain fittings assembled with protective and transport frames, during transportation by truck or vessel from the workshop to the sites and to the drilling rig. The frame system 1 is secured with cables from the eyes to the brackets on the vehicle trailer or deck.

A diagram of the transfer of the transport frame 4 from the working horizontal position to the transport vertical position is shown in FIG. 5-7.

The protective frame 3 is made with the possibility of installation on the transport frame 4 by means of fixation, including, for example, a bolt or hairpin connection. The surface fountain armature 2 is installed in the protective frame 3 in places 17 for mounting, containing many holes for mounting the surface fountain armature 2 by means of bolts. Each frame module 5.6 is provided with such a mounting location 17. The protective frame 3 contains at least two attachment points 17, in the present embodiment, the protective frame 3 contains four attachment points: there are two attachment points 17 on the first frame module 5, the first attachment point 17 being located on the lower part of the first frame module 5, as 2, and the second mounting location 17 is located at the top of the first frame module 5, the second location 17 is not shown in the drawings. Similarly located mounting points 17 on the second frame module 6.

Thus, the protective frame 3 is configured to install surface-mounted fountain fittings 2 therein by attaching the surface-mounted fountain fittings 2 in at least two mounting locations 17, with at least one first mounting location 17 located on a beam 10 of the first frame module 5, and at least one second mounting location 17 is located on the beam 10 of the second frame module 6.

Thus, the first frame module 5 and the second frame module 6 are connected to the surface fountain 2 and connect the frame modules to each other relative to the surface fountain 2.

When installing the surface of the fountain valves 2 in the protective frame 3, it is oriented so that the valves 8 of the fountain valves 2 are located in accordance with the location of the platforms 7 for the valves on the protective frame 3.

The surface fountain reinforcement 2 is protected from falling objects and other damage in the horizontal and transport vertical position of the frame system 1 by the first mesh 11 and the second mesh 12, which in a non-limiting embodiment of the invention is made of fiberglass, and which is attached to the protective frame 3 when using bolted connections 13. The use of fiberglass nets can reduce the weight of the protective frame 3 while maintaining its protective functions.

Also on the protective frame 3 is equipped with bumpers 18 bumpers are provided, designed to protect the protruding parts of the surface water valves 2, in particular valves 8, the pipe 14 for the elevator, as well as indicators 9 for visual inspection of valves 8.

To simplify the assembly of modules 5 and 6 of the protective frame 3, guide rods 19 are provided on the mating side of the first module 5, and recesses (not shown in the drawings) for the rods 19 are provided on the mating side of the second module 6. This increases the rigidity of the protective frame 3 and redistribution of stresses created in it during operation. Thus, the described design of the protective frame 3 allows you to install in the protective frame 3 various modifications of the surface fountain fittings, if it is possible to drill threaded holes in it at the junction with the frame.

The protective frame 3 also contains supports 20 for a hard flow line and a line of silencing the surface of the fountain valves 2, made with the application of an elastomeric coating to ensure damping.

And for fixing the connected flexible flow line and jamming line (not shown in the drawings), the protective frame 3 has adjustable brackets 21, which ensure the safety of both the connection itself and the personnel.

The versatility of the protective frame 3 is achieved due to the fact that it is a prefabricated one, consists of two modules 5 and 6, the bumpers 18 are detachable, which also contributes to the ability to install the protective frame 3 on various modifications of the surface fountain.

As shown in FIG. 4, the transport frame 4 is a spatial structure including a working part 22 and a transport part 23 arranged mutually perpendicularly, the working and transport parts 22 and 23 of the frame 4 contain beams 24 of an I-section connected to each other by a welded joint. The working part 22 includes two hollow beams 25 for the forks of the loader. The working part 22 contains the second transportation eyes 26 located at the ends of the beams 24 of the working part 22, and the transportation part 23 also contains the third transportation eyes 27 located at the ends of the beams 24 of the transport part 23.

The protective frame 3 is installed on the transport frame 4 in a position in which the nozzle 14 under the elevator is located along the working part 22 of the transport frame 4.

The transport frame 4 is located in a working horizontal position, when its working part 22 is located in a horizontal position, and the transport part 23 is in a vertical position; and the transport frame 4 is located in the transport vertical position, when its working part 22 is located in the vertical position, and the transport part 23 is in the horizontal position.

When the transport frame 4 is in a horizontal position assembled with a protective frame 3 with a surface mounted fountain reinforcement 2 installed in it, it is possible to test the surface fountain reinforcement 2, as well as supplement it with missing parts.

The transport frame 4 is made with the possibility of its transfer from the working horizontal position to the transport vertical position and vice versa.

The operation method of the frames includes the following steps. First, the surface fountain armature 2 is installed in the protective frame 3 by placing the first module 5 of the protective frame 3 and the second module 6 of the protective frame 3 around the fountain arm 2 with the subsequent connection of the surface fountain arm 2 with the first frame module 5 and the second frame module 6 in place 17 for fastenings of surface fountain fittings 2. At the same time, the first frame module 5 and the second frame module 6 of the protective frame 3 are interconnected using rods 19 on the first frame module 5 and the counter recesses on the second frame module 6. Then assembled protective frame 3 installed therein christmas tree 2 is mounted on the working portion 22 of conveyor frame 4, when the conveying frame 4 is in the working horizontal position. To facilitate the installation of fountain valves 2, the working part 22 of the transport frame 4 is provided with guides 28, as best seen in FIG. 4, where the transport frame 4 is illustrated separately.

Further, using at least one crane, the frame system 1, that is, the transport frame 4 together with the protective frame 3 with the surface mounted fountain reinforcement installed therein, is transferred from the working horizontal position to the transport vertical position. When moving the transport frame from horizontal to vertical, use the first transport eyes 15 of the protective frame 3, or use the second transport eyes 26 located at the ends of the beams 24 of the working part 22 simultaneously with the third eyes 21 located at the ends of the beams 24 of the transport part 23.

When moving from a working horizontal position to a transporting vertical position, additional stability is achieved thanks to the thrust bearings 29.

In FIG. 6 it can be seen that the second eyes 26 and the third eyes 27 can be used to transfer the frame system from the working position to the transport using two cranes, as well as the first eyes 15 can be used to transfer the frame system from the working position to the transport using one crane.

The position of the frame system illustrated in FIG. 7, is used both for transportation and for connecting the surface fountain fittings to the sliding pipe section and the further transportation of the frame system 1 with the surface fountain fittings 2 and the sliding pipe section attached to it.

In the context of the present description, the words “first”, “second”, “third”, etc. used in the form of adjectives solely to distinguish the nouns to which they relate from each other, and not for the purpose of describing any specific relationship between these nouns. So, for example, it should be borne in mind that the use of the terms “first eyes” and “third eyes” does not imply any order, attribution to a certain type, nor does their presence in itself imply that some “second eyes” must exist in a given situation, despite the fact that in the particular case there are also "second eyes".

The embodiment of the proposed technical solution set forth in the text of the application is not the only possible one; within the scope of the claims, there may be other embodiments of the proposed technical solution that are obvious to a person skilled in the art. The present description should be considered only as providing understanding of the proposed technical solution, and not determining its scope and boundaries.
