Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the extraordinary ocean for being used to discard oil/gas well closure and old platform removal of the utility model
Platform includes: that deck 1, cantilever beam drilling well packet 2,4, three fixed life building 3, pillar heavy sea crane general's pillars are flat
Platform deck loop wheel machine 5, heavy sea crane 4 are placed on the stern on deck 1, and three general's pillar platform deck loop wheel machines 5 distinguish position
Stern, port and starboard in deck 1 can meet on different directions according to the different location of platform berthing, inboard outboard
Use demand, while the general's pillar platform deck loop wheel machine working range for being located at deck stern can cover entire cantilever beam area
Domain, and comb loop wheel machine when can serve as drillng operation.
Deck 1 is jack-up unit, and area is up to 2200 square metres, and design strength is high, and operation stability is strong, Platform Designing
The conventional depth of water that job area is 400 feet, meets the use under norwegian continental shelf and U.K. North Sea sea area adverse weather condition
It is required that.
Cantilever beam drilling well packet 2 is removable structure, can be with working conditions such as complete independently drilling well, well workover and shut-in wells.
Fixed life building is the movable life building module that can accommodate 180 people and selective configuration simultaneously, combination
Seating capacity is more than 500 people afterwards.
Pillar heavy sea crane 4 is the construction module that can lift by crane large-tonnage, is met to old platform retired demolition
When requirement, such as can be 2200 tons of pillar heavy sea cranes of a service load.Pillar heavy sea lifting
Machine 4 is placed on the stern of jack-up unit, is greatly expanded the functional diversity of self-elevating ocean platform.
Three general's pillar platform deck loop wheel machines 5 are located at platform stern, port and starboard, can be according to platform berthing
Different location, meet on different directions, the use demand of inboard outboard, at the same stern deck hang working range can cover it is whole
A cantilever beam region, and comb loop wheel machine when can serve as drillng operation.Preferably, three 5 works of general's pillar platform deck loop wheel machine
Make 70 tons of load.
It, will be by the light-duty of cantilever beam drilling well packet 2 when the extraordinary ocean platform of the utility model is used as well workover and blocks platform
Drilling machine completes the related operation of some column, such as: stifled well and abandoned well, well workover, drilling well (within 5000m), well logging and well cementation.Cantilever
The top drive system gone up and down by gear-rack drive is installed, the utility model is not equipped with tradition in the derrick of beam drilling well packet 2
Winch and tourist bus in meaning, included reduction gearbox and driving pinion are driven in the promotion and decline for pushing up drive by top completely, and match
The rack gear of installation in derrick is closed to realize, 250 tons of the max. hook load of top drive can complete stifled well and abandoned well and 5000
Deep drillng operation is bored to the range of needs of load within rice.Meanwhile above-mentioned cantilever beam is equipped with coiled tubing in deck stern
Reel is then equipped with coiled tubing injection head on drilling floor surface, completes workover treatment by coiled tubing.In addition, well logging and well cementation
It can then be realized by the well logging unit being mounted in cantilever beam with well cementation unit.In addition, be also equipped on rig floor iron driller,
Throttle well killing manifold, standpipe manifold etc., driller house is then mounted on the pedestal above cantilever beam deck, unobscured, can be bowed
It looks down from a height entire cantilever beam region and rig floor region.Double driller's chairs are equipped in driller house, every chair is furnished with two sides large scale touch display screen,
Entire drilling well is all highly integrateable on driller's chair key and touch screen in relation to operating and being arranged.
When being used to remove marine old platform facility, floor space can be used to increase, use heavy sea crane 4
The drilling well packet installed cantilever beam and thereon integrally removes, and the space vacateed is used to store the knot dismantled from old facility
Structure object.In order to achieve this, the cantilever beam and its support construction of the utility model special type ocean platform break conventional design thinking,
Cantilever beam support construction is made of the support construction and connection pin shaft being welded on main hull, and pin shaft is machined with certain taper, side
Just plug, the positive stop end contacted on pin shaft with cantilever beam are machined with concave station face, and after pin shaft is inserted into operating position, pin shaft stops
Moved end is then equipped with the structure for limiting its axial movement.It, can be by pulling out support knot if cantilever beam needs overall pulling down after shipment
Pin shaft on structure realizes the overall pulling down to cantilever beam, structure simple and flexible, safety can to easily hang away cantilever beam
It leans on.
Cantilever beam is connect by pin shaft by the utility model with the support construction on main hull, as accommodation platform with tear open
Platform is solved in use, the connection pin shaft of support construction can be unclamped and remove entire cantilever beam, is designed in cantilever beam main structure
Suspension centre facilitates heavy sea crane 4 integrally to remove cantilever beam.In the case where removing operating condition, higher frequency of use is heavy sea
General's pillar platform deck loop wheel machine of foreign crane 4 and platform stern, two loop wheel machine cross-references are sequentially completed marine related knot
The dismantling of structure facility lifts task.
In addition, the base construction design aspect of the pillar heavy sea crane in platform stern, use by laterally and
Longitudinal each twice bulkhead and corresponding stiffener and reinforcement support composition, structure are attached through deck with hull main structure,
Effective support is formed to loop wheel machine main body.The base construction nearly 27 meters of height more than deck are made using the form of insertion hull
There is pedestal enough intensity to resist vertical force and moment of flexure, while for dispersion level power, increase in pedestal and deck connecting place
Multiple brackets make the load of all directions in horizontal plane be effectively passed to surrounding support structure, meet various operating condition bottom base knots
The requirement of the intensity, rigidity and stability of structure, and structure type is simply convenient for constructing.
Fixed life building is in addition to the field in well workover and dismounting operation, as office staff and inhabitation on platform
Institute is outer, which is also an option that on the deck position removed after cantilever beam, the life building module of installation activity formula, two parts
Life building is combined with each other, and accommodating personnel's number will be more than 500 people, can be used as accommodation platform use.
The utility model selects removable cantilever beam drilling well packet, then the pillar heavy sea for cooperating platform stern to install rises
Heavy-duty machine is greatly enriched the functionality of platform, makes it that can both become workover platform, can also be used as offshore structures dismounting
Platform.Space after cantilever beam removes flexibly is used, and can not only store the works after removing, but also can place movable
Life building module greatly expands the working platform personnel that can accommodate inhabitation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
