Description

A kind of deep water subsea manifold structure

Technical field

The utility model relates to the deep water subsea manifold structure of using 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 utility model provides a kind of safe and reliable deep water subsea manifold structure.

For achieving the above object, the utility model is taked 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 utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model 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 utility model 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 utility model more safe and reliable.3, the utility model 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 utility model can be widely used in the various deepwater environments.
