Description
Technical field
The present invention relates to a kind of settling type self installation platforms of band large size well head.
Background technique
With persistently dropping for international oil price, the development benefit of offshore oil and gas field worse and worse, reduces Offshore development engineering
Investment seems particularly important.In China, marine oil field exploitation mainly uses jacket platform, and the installation of jacket platform needs dynamic
With large-scale floating crane resource, often offshore construction is costly, some can account for the 1/3 of construction investment, and jacket platform
It needs after jacket installation, then carries out chunking installation, installation and connection debug time are longer, while jacket platform exists
During later period throws aside, it is also desirable to employ large-scale floating crane resource, this all greatly increases the construction investment in oil field.For some economy
The shorter marginal oil field of the time limit is usually larger due to investing, and benefit is lower, it is difficult to develop.
Summary of the invention
The object of the present invention is to provide a kind of settling type self installation platform of band large size well head, it can be achieved that self installation, is not required to
Crane barge resource is employed, the later period is reusable, and multiple well heads can be arranged on platform, more than 50 mouthfuls of wells, can be used for large size
Oil field development.
The settling type self installation platform of band large size well head provided by the present invention, it includes platform body and lower part bottom hull；
It is connected between the platform body and the lower part bottom hull by spud leg；
The well head guiding extends vertically through the platform body and the lower part bottom hull；
The well head guiding is for limiting and fixing waterproof casing.
In the settling type self installation platform, penetration pile is equipped in the spud leg.
In the settling type self installation platform, one end of the penetration pile is extended from lower part bottom hull end, to stretch
Enter to seabed, increases the stability of platform.
In the settling type self installation platform, bracket is axially arranged with along it in the spud leg, is realized by the bracket
Being fixedly connected between the spud leg and the penetration pile.
In the settling type self installation platform, the gap between the spud leg and the penetration pile can be carried out at grouting
Reason, can increase the bearing capacity and stability of platform.
In the settling type self installation platform, set along the well head of the main platform body and lower part bottom hull guiding
There are several waterproof casings, installation process is as follows: after stage+module is in place, being squeezed into using drill ship by well head guiding described
The numerous waterproof casings and hull (platform i.e. of the present invention) of bank are connected to form a whole by waterproof casing, improve water proof
The rigidity of casing increases anti-wave ability.
In the settling type self installation platform, the well head guiding is set to the intermediate region or side of the main platform body
At least 50 mouthfuls of wells or more can be set as needed in region.
In the settling type self installation platform, the platform body is in structural configuration, with steady when meeting towage
Property require.
When the platform is installed, the spud leg can be controlled by lifting device (can only rent when in place) and be used for the platform
From lifting installation.
After the completion of oil field produces, by the penetration pile and above-mentioned waterproof casing at excision mud face, filled by lifting
Promotion is set, and realizes that towage migrates, achievees the purpose that throw aside, platform is into after dock, by taking out internal penetration pile, it can be achieved that weight
It is multiple to utilize.
Self installation wellhead platform proposed by the present invention with bottom hull is due to taking above technical scheme, with following excellent
Point:
1, platform can be in place with self installation；The present invention can be realized using lifting device to lower part bottom hull and main platform body
Control realizes the installation to platform that is, under the buoyancy of lower part bottom hull and main platform body, does not need to employ crane barge resource.
2, bank can arrange multiple well heads, as more than at least 50 mouthfuls of wells, can satisfy the exploitation of shallow water large oilfield；
3, platform lower be equipped with bottom hull, can play the role of platform antidumping it is anti-settling and increase platform stabilization；
4, platform upper structure is hull form, can satisfy stability requirement when towage；
5, waterproof casing is oriented to by platform well mouth area and bottom hull guiding is connected, and stability is preferable；
6, platform is in towage, the penetration pile with certain length in spud leg, it is ensured that is completed after in place with small-sized crane barge
Piling work, cost saving.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing, but the invention is not limited to following embodiments.
As shown in figure 3, the schematic diagram after installing in place for self installation wellhead platform of the present invention with bottom hull, it includes hull
The platform body A of structure type and the floor map of lower part bottom hull E, platform body A as shown in Figure 1, platform body A side
Region is production area.Another side region is bank B, several well heads guiding F is arranged, for limiting and fixing waterproof casing
G.It is equipped with the position corresponding position of platform body A that quantity is identical and the identical well head of arrangement is oriented to F, such as Fig. 2 on the bottom hull E of lower part
It is shown.It is connected between platform body A and lower part bottom hull E by 4 spud leg D, as shown in figure 3, the wherein internal structure of spud leg D
As shown in figure 5, being internally provided with bracket (not marking in figure).When installing wellhead platform of the present invention, in platform body A and lower part bottom hull
Under the natural buoyancy effect of E, the installation to platform can be realized using lifting device C.As shown in figure 4, stage+module of the present invention
It after in place, is squeezed into spud leg D by drill ship penetration pile H, and passes through lower part bottom hull E and extend to seabed, stake is realized by bracket
Being fixedly connected between leg D and penetration pile H, and the gap between spud leg D and penetration pile H carries out grouting treatment, it is flat to enhance
The bearing capacity and stability of platform.As shown in fig. 6, being led after platform is driven piles by the well head of platform body A and lower part bottom hull E
Waterproof casing G is squeezed into F, and waterproof casing G is fixed, waterproof casing G and platform body A is made to form an entirety, with
Improve the rigidity of waterproof casing G.As shown in fig. 7, platform in towage, passes through the penetration pile H and waterproof casing at excision mud face
