Description

A kind of deep-sea floating type well drilling BOP storage and transportation apparatus
Technical field
The present invention relates to a kind of in order to store and the device of movement preventer, especially a kind of deep-sea floating type well drilling BOP storage and transportation apparatus.
Background technology
Semisubmersible drilling platform is the offshore structures for drilling well, and mainly comprise the equipment etc. such as drilling well, power, communication, navigation, its middle and upper part is spar deck, and bottom is two pontoons, connects with support post.
Drilling equipment comprises drilling equipment, power-equipment, cementing equipment, formation testing equipment, lifting, anchoring and mooring system and other auxiliary equipment, and drilling equipment wherein mainly comprises blowout preventer set, marine riser, LMRP and other ancillary services.
The crucial well-control equipment of blowout preventer set is that BOP, BOP are preventer, is for closing well head, the security seal wellhead assembly preventing gas blowout accident from occurring in the operation process such as formation testing, well workover, completion.
The agent structure of BOP mainly bears High Pressure, and inner critical component is valve member, flashboard, and by Flange joint between parts, flange can bear the weight of whole BOP, transfers operation for BOP.But because the miscellaneous part of BOP cannot bear larger external force; therefore under normal circumstances; BOP is set with BOP framework; lead during to transfer BOP and protective effect; not only can support the whole weight of gas BOP, also can prevent BOP body because the motion that hull waves generation makes itself and hull collide.The frame construction that BOP framework entirety is open in surrounding, comprise the upright of frame of four vertical directions, upright of frame is provided with the back-up block in order to location, and back-up block is arranged on upright of frame, and extend out to the periphery of upright of frame in the horizontal direction.When being transferred to seawater by BOP, BOP is connected with marine riser and the LMRP for connecting BOP and marine riser.
Drilling equipment carries out transferring, migrate and fixing mainly through offshore boring island, and offshore boring island is provided with moon pool, well head etc., BOP and LMRP is usually placed in moon pool two ends, and is provided with slideway and dolly in the both sides of moon pool, for the handling of blowout preventer set.
Before by blowout preventer set work, usually need to store blowout preventer set, movement, the operation such as pressure testing, blowout preventer set is sent to or is moved apart pithead position, transfer or field-strip to complete.
Wherein blowout preventer set mainly comprises following operating process:
A, storage
Before the mounting, blowout preventer set is stored on offshore boring island usually;
The common way of prior art on offshore boring island, divides special storage area or is directly stored in moon pool.
B, movement
In drilling process, need by transportation equipment by blowout preventer set from storage location to pithead position, and transfer from well head, install;
In prior art, common way to utilize guide rail and the dolly of moon pool side, after blowout preventer set is moved to well head, removed by dolly, and blowout preventer set hangs in in well head by recycling loop wheel machine.
C, pressure testing
At deep sea drilling before blowout preventer set is transferred, need to carry out pressure testing to blowout preventer set, after pressure testing, carry out last installation, connect each parts of blowout preventer set and standpipe successively.
In order to realize aforesaid operations, usually need multiple equipment be separated from each other with the use of, it has following weak point:
1, to the sequence of operations step of the storage of BOP and framework thereof, movement, pressure testing, need to have been matched by multiple devices, relatively independent between each equipment, need take larger space when arranging, meanwhile, operating process is comparatively loaded down with trivial details.
2, by pulley and guide rail coordinate movement is carried out to blowout preventer set time, blowout preventer set easily because hull is with the motion of the water surface, along lead rail axis to the slippage of generation nature.
When 3, carrying out movement by pulley and guide rail cooperation to blowout preventer set in prior art, blowout preventer set easily because hull is with the motion of the water surface, guide rail is turned on one's side.
4, blowout preventer set is when movement, and Yi Yin and hull collide and damage.
The reason not adopting roller assembly to match with guide rail in prior art is: when BOP framework stores above deck, for the consideration of safety and stability, usually need by BOP frame hoisting from guide rail, therefore, according to the form that pulley guide rails coordinates, at BOP frame hoisting to being difficult to guide rail to be aimed at roller during guide rail, and also not easily make it fixing when BOP framework is parked on hull.
