Description

Production tree transfers the linking arm of guided tooling

Technical field

The utility model belongs to offshore production implement technical field, is related to a kind of transferred using semisubmersible platform and recovers the oil The guided tooling of tree, especially production tree transfer the linking arm of guided tooling.

Background technology

Semisubmersible platform relies on the advantages such as its deck space is open, operation on the sea is steady, changing load is larger, has become Deep-sea, off-lying sea perform one of most important marine frock of the production operations such as exploration, drilling well, oil recovery, and production tree is in oil Test oil (gas), or a kind of important well head control device during flowing well oil recovery are carried out after (gas) well completion.

Production tree is delegated to seabed by drilling rod, during being transferred in production tree, whole platform can because by The influence of the adverse circumstances such as marine wind, wave, air-flow, and rocking for the multiple directions such as rolling, pitching, heaving occurs, thus, adopt Oil tree directly threatens equipment and put down inevitably because the inertia of its own and the other structures part of platform collide The safety of platform itself.

Therefore, there is an urgent need to can have a kind of equipment or structural member to provide guiding and support for the decentralization of production tree, it is ensured that The steady decentralization of production tree and the safety work of whole platform.

Fixed guide frame part can produce interference under non-decentralization production tree operating mode between other operations, and for a long time The space on deck is occupied, is the significant wastage to the confined space；

And single guide device can not spatially effectively act as guide effect in whole decentralization, and due to equipping cost Costliness, it is difficult to be used.

Therefore, it can be that the technological equipment that production tree transfers guide function can be achieved by fast assembling-disassembling that in the market, which is badly in need of a kind of, Come out, neither for a long time take deck the confined space, again can Reusability, for production tree decentralization provides be oriented to and support, really Protect the steady decentralization of production tree and the safety work of whole platform.

Production tree decentralization guided tooling should can adapt to various sizes of production tree, also can adapt to various sizes of Drilling rod, therefore, for production tree leading arm and drilling rod leading arm, it is required for by the linking arm with different length according to existing The actual conditions of field carry out collocation use, to meet that production tree transfers the needs being oriented under various different operating modes.

Therefore say, the steady decentralization role of the setting of linking arm for production tree is vital.

The content of the invention

The purpose of this utility model is overcome the deficiencies in the prior art or defect, there is provided a kind of production tree decentralization is oriented to work The linking arm of dress, it can be oriented to according to the actual condition at scene from the linking arm and production tree leading arm and drilling rod of different length Arm carries out collocation use, can meet the needs of production tree decentralization is oriented under various different operating modes.Carried for the steady decentralization of production tree For strong equipment guarantee, guiding and support are provided for the decentralization of production tree, it is ensured that the steady decentralization of production tree is put down with whole The safety work of platform.

To achieve these goals, the utility model employs following technical scheme：

The linking arm for a kind of production tree decentralization guided tooling that the utility model is related to, it is characterised in that including some The square steel tube that length does not wait, the axial both ends of every square steel tube are evenly equipped with several and transfer adopting for guided tooling with production tree respectively The connecting hole that oil tree leading arm or drilling rod leading arm and slipping base are adapted；One end positioning of the linking arm is set in described adopt The afterbody of oil tree leading arm or drilling rod leading arm, its other end and the sliding rail for being movably connected in production tree decentralization guided tooling On leading arm slipping base grafting, and be located by connecting and be integrated by the corresponding bolt being located in its connecting hole, overall structure Into can it is adjoint, guiding production tree or drilling rod along the sliding rail vertical direction decentralization standalone feature structural member.

The linking arm of above-mentioned production tree decentralization guided tooling, wherein,

Front and rear tube wall of the connecting hole along linking arm both ends on the linking arm is axially centered to be symmetrically distributed on same level On line.

Connecting hole on the linking arm is uniform axially on the front and rear tube wall at both ends in plum blossom-shaped.

By adopting the above-described technical solution, the utility model has advantages below and beneficial to effect compared with prior art Fruit：

Because the linking arm for the production tree decentralization guided tooling that the utility model is related to includes what some root long degree did not waited Square steel tube, the axial both ends of every square steel tube be evenly equipped with several respectively with production tree leading arm or drilling rod leading arm and sliding base The connecting hole that seat is adapted；One end positioning of linking arm is set in the afterbody of production tree leading arm or drilling rod leading arm, and its is another End is plugged in the slot of the slipping base of production tree decentralization guided tooling, and three, which is located by connecting, to be integrated, and being monolithically fabricated can companion The standalone feature structural member transferred with, vertical direction along sliding rail of guiding production tree or drilling rod.

Collocation use is carried out from the linking arm and production tree leading arm and drilling rod leading arm of different length, can be met various The demand that production tree decentralization is oriented under different operating modes.

Front and rear tube wall of the connecting hole along linking arm both ends on linking arm it is axially centered it is symmetrical it is uniform in the same horizontal line, Can also be in that plum blossom-shaped is uniform axially on the front and rear tube wall at both ends.It is spaced apart in the same direction to open up multigroup spiral shell Keyhole, on the one hand by multigroup bolt connection leading arm slipping base, production tree leading arm and drilling rod leading arm, knot can be reduced Local stress on structure, on the other hand, by selecting the bolt hole on diverse location, the swinging radius of drilling rod leading arm can be adjusted From adapting to different size of well head size.

In addition, the linking arm that the utility model is related to is provided simultaneously with following characteristics together with whole guided tooling：

1. design innovation：Naval Architecture and Ocean Engineering field is all designed without such guided tooling in world wide, belongs to industry Pioneer invention；

Successfully tried out 2. belonging to first and covering：This frock is assemblied on BT4000 semi-submersible type assistance platforms first, and is tried out into Work(；

3. it is strong to be oriented to bearing capacity：Suitable for 120t and following production tree under the environmental condition comprehensive function such as stormy waves stream External applied load；

4. manufacturing cost is low：Linking arm overall structure is all made up of conventional ship plate, and in light weight, manufacturing cost is low, And can Reusability；

5. purposes is more：Both the connection that can be used between production tree leading arm and slipping base, drilling rod can be used for be oriented to again Connection between arm and slipping base, each form the integral structure component with standalone feature.
