Along with the needs of marginal field, coastal waters exploitation, wellhead platform and wellhead protecting frame are widely applied.Conventional manifold posture wellhead platform or wellhead protecting frame adopt the upper brace of post and beam space frame structure; bottom adopts jacket structure and steel pile foundation to carry environmental load; jacket need for waterproof casing arranges multiple-layer horizontal guide frame; form of structure is complicated; coupling stiffness is more weak, higher to waterproof casing requirement of strength.This conventional manifold rack and panel construction form requires higher to construction, needs to build at the extra large work harbour of specialty, then draws shipment or with the upper barge of large-scale floating crane lifting, is transported to installs marine site with barge container.Jacket and upper brace Attention problems need to use large-scale floating crane, and piling bar is squeezed into be needed to use pile hammer, and need to be in the milk with jacket to be connected, and Attention problems is costly.For offshore oil and gas field exploitation, adopt conventional catheters posture wellhead platform scheme, exploitation total cost is high, and rate of return on investment is low, even causes oil gas field without Development volue.
Present patent application proposes a kind of step barrel mast formula wellhead protecting frame just in this context.
Utility model content
Main purpose of the present utility model is the above-mentioned shortcoming overcoming prior art existence, and provide and propose a kind of step barrel mast formula wellhead protecting frame, by the upper chunk structure adopting box deck to replace traditional platform, decrease pipe crimping usage quantity, reduce construction difficulty, during shipment transport, fixed solution is simple, and fixed structure steel using amount is few; By adopting top barrel mast and bottom barrel mast, simplify wellhead protecting frame support structure, buoyancy can be provided during Attention problems, reduce the requirement to crane barge, waterproof casing pillar is provided with in barrel mast, make waterproof casing from environmental load, and cover to punch at lower sleeve capital whenever necessary and increase well head guiding; Pile foundation adopts super-large diameter suction pile, can from floating during marine transportation, and Attention problems does not need large-scale floating crane, and wellhead protecting frame can reuse, high financial profit.
The purpose of this utility model is realized by following technical scheme:
A kind of step barrel mast formula wellhead protecting frame; include superstructure and substructure; it is characterized in that described superstructure is made up of box deck and support column from top to bottom; described box deck is connected by welding manner with described support column; described substructure is made up of column, top barrel mast, bottom barrel mast and pile foundation from top to bottom; described column, described top barrel mast, all to be connected by welding manner between described bottom barrel mast and described pile foundation; described column is positioned at below described support column, and by connecting with welding manner.
Waterproof casing pillar is provided with in described support column, described top barrel mast, described bottom barrel mast.
Described lower sleeve capital covers to punch increases well head guiding.
Described pile foundation adopts diameter to be greater than the suction pile of 15m.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, by the upper chunk structure adopting box deck to replace traditional platform, decrease pipe crimping usage quantity, reduce construction difficulty, during shipment transport, fixed solution is simple, and fixed structure steel using amount is few; By adopting top barrel mast and bottom barrel mast, simplify wellhead protecting frame support structure, buoyancy can be provided during Attention problems, reduce the requirement to crane barge, waterproof casing pillar is provided with in barrel mast, make waterproof casing from environmental load, and cover to punch at lower sleeve capital whenever necessary and increase well head guiding; Pile foundation adopts super-large diameter suction pile, can from floating during marine transportation, and Attention problems does not need large-scale floating crane, and wellhead protecting frame can reuse, high financial profit.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in detail.
As shown in Figure 1, the utility model includes superstructure and substructure, superstructure is made up of box deck 1 and support column 2 from top to bottom, box deck 1 is connected by welding manner with support column 2, substructure is made up of column 3, top barrel mast 4, bottom barrel mast 5 and suction pile 7 from top to bottom, column 3, top barrel mast 4, all to be connected by welding manner between bottom barrel mast 5 and suction pile 7, column 3 is positioned at below support column 2, by connecting with welding manner, suction pile 7 is diameter 16m suction pile.Be provided with waterproof casing pillar 6 in support column 2, top barrel mast 4, bottom barrel mast 5, bottom barrel mast 5 top cover can punch and increase well head guiding.
