The three-layer structure is welded into a firm whole body by the main bearing column and the four vertical columns; the main bearing structure and the four vertical columns form a structure base together; and the invention has the advantages of less installation interface and frequency, high system integrated level, high integral structure stability, safety and reliability and can be widely used for various subsea manifold systems for deep sea petroleum extraction.
Description
Technical field
The present invention relates to the deep water subsea manifold structure of use in the casing-head gas exploitation of a kind of deep-sea.
Background technology
Obtained using widely in the deep water hydrocarbon field exploitation of subsea production system all over the world, it is subjected to the disaster weather effect less, and good reliability is one of the key technology in economic, efficient marginal field development, deep-sea oil gas field.Because China is starting late aspect the exploitation of deep water hydrocarbon field, therefore carrying out under water in China, Study on Production Technology is very urgent and necessary problem to the economic development that China adapts to following deep water hydrocarbon field.
The manifold structure can provide support and protect for pipeline and equipment, and provides the interface for operations such as the installation of equipment, replacing, maintenances.Because the subsea manifold structural volume is big, Heavy Weight, expense height, the application scenario is many, and the form of manifold structure is determining safety, reliability, applicability and the operability of whole manifold system, and therefore safe, reasonable, economic subsea manifold structure Design and application is very necessary.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of safe and reliable deep water subsea manifold structure.
For achieving the above object, the present invention takes following technical scheme: a kind of deep water subsea manifold structure, it is characterized in that: it comprises the three layer construction of being made up of superstructure, middle level structure and substructure, and by four root posts and the manifold base that main bearing structure is formed; Described three layer construction all adopts H shaped steel to be welded, and the welded top of described superstructure has steel plate, is welded with diagonal brace between the described upper and lower layer structure; Described four root posts link into an integrated entity described three layer construction, and described four root post tops are respectively arranged with the hanger that is used to lift, described main bolster stake is welded on the described substructure, and the bottom of described column and main bolster stake is welded with one respectively and is used to be connected suction anchor basis bell mouth shape fairlead.
Described three layer construction and manifold base are provided with some anticorrosion anode blocks.
The outside of the bell mouth shape fairlead of described column and main bolster stake bottom is provided with plurality of strengthening ribs.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention is owing to be welded into a firm integral body with three layer construction by main bolster stake and four root posts, form pier by main bearing structure and four jointly with column, therefore not only installation interface and number of times are few, the level of integrated system height, and the overall structure steadiness is good, safe and reliable.2, the present invention is owing to be provided with four root posts, therefore can prevent the rotation and the inclination of manifold structure, and can take all factors into consideration according to the magnitude of load of installation requirement and influence rotation and inclination, lead quantity on the suction anchor basis of determining to dock with column makes use of the present invention more safe and reliable.3, the present invention is owing to be provided with the guiding of bell mouth shape in main bolster stake and column bottom, therefore can successfully guide with guide peg on the suction anchor basis to dock, and installs very convenient.The present invention can be widely used in the various deepwater environments.

The specific embodiment
Be described in detail of the present invention below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention is the design that the manifold structure in the deep water subsea manifold system 10 is carried out, the present invention includes the three layer construction of forming by superstructure 1, middle level structure 2 and substructure 3, and by four root posts 4 and the manifold base that main bearing structure 5 is formed.Superstructure 1 is welded by H shaped steel and steel plate, and main effect is to bear the underwater robot operation load, and the top is weighed down thing and impacted, and equipment self-weight etc. also provide protection for the equipment in the manifold system 10 of below simultaneously.Middle level structure 2 is welded by H shaped steel, mainly be to bear and transmit superstructure load, for the diagonal brace 6 between superstructure 1 and the substructure 3 provides support, remain with enough height space between middle level structure 2 and the superstructure 1 simultaneously, guarantee laying and the operating space of terminal board.Substructure 3 is welded by H shaped steel, is mainly whole manifold system internal unit and pipeline and provides support.Main bearing structure 5 is integrally welded with substructure 3, and four root posts 4 are integrally welded with upper, middle and lower layer structure 1,2,3 respectively, and then constitute a total.A hanger 7 will be welded in the top of every root post 4, to be used for integrally-built lifting.The bottom of four root posts 4 and main bearing structure 5 is welded with a bell mouth shape fairlead 8 respectively, be used to guide the manifold structure to dock smoothly with the suction anchor basis, pass to the suction anchor basis with deadweight, operation load, environmental load with manifold system 10, and restriction manifold system 10 carries out orientation and attitude in the kimonos labour process in installation, guarantees that manifold system 10 is in rational service state.
The general structural central post of suction anchor is with after main bearing structure 5 docks, just can reach the anti-effect of selecting, preventing inclination as long as there is a guide peg to dock again with column 4, the present invention can be according to weight, the bearing load of total self, and the effect of external environment condition load is calculated, need to be provided with several guide pegs that dock with column 4 on the suction anchor to be chosen in, four guide pegs can be set at most dock with four root posts.
In the foregoing description, can also to prevent the corrosion of seawater, prolong application life of the present invention on the upper, middle and lower layer structure 1,2,3 and on column 4 and the main bearing structure 5 some anticorrosion anode blocks 9 being set all to steel structure material.
In the foregoing description, bell mouth shape fairlead 8 outsides of four root posts 4 and main bearing structure 5 bottoms can evenly be provided with plurality of strengthening ribs 11, to strengthen the intensity of horn mouth structure.
The various embodiments described above only are used to illustrate the present invention, and wherein the structure of each parts, connected mode etc. all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement all should not got rid of outside protection scope of the present invention.
