Oil field development.
Settling type self installation platform with large-scale well head provided by the present invention, it includes platform body and bottom mat；
It is connected by spud leg between described platform body and described bottom mat；
Described well head guiding extends vertically through described platform body and described bottom mat；
Described well head guides for limiting and fixing waterproof casing.
In described settling type self installation platform, in described spud leg, it is provided with penetration pile.
In described settling type self installation platform, one end of described penetration pile is extended from described bottom mat end, to stretch
Enter the stability increasing platform to seabed.
In described settling type self installation platform, it is axially arranged with bracket along it in described spud leg, is realized by described bracket
Being fixedly connected between described spud leg and described penetration pile.
In described settling type self installation platform, the gap between described spud leg and described penetration pile can be carried out at grouting
Reason, can increase bearing capacity and the stability of platform.
In described settling type self installation platform, the described well head guiding along described main platform body and described bottom mat sets
There are some waterproof casings, installation process is as follows: after stage+module is in place, squeeze into described by described well head guiding using drill ship
Waterproof casing, numerous waterproof casings of bank and hull (i.e. platform of the present invention) is connected and forms an entirety, improve water proof
The rigidity of sleeve pipe, increases anti-wave ability.
In described settling type self installation platform, described well head guides zone line or side located at described main platform body
Region, can be arranged as required to more than at least 50 mouthfuls wells.
In described settling type self installation platform, described platform body is in structural configuration, steady during towage to meet
Property require.
When described platform is installed, described spud leg can be controlled to be used for this platform by lowering or hoisting gear (can rent only when in place)
From lifting install.
After the completion of oil field produces, by excising described penetration pile and the above-mentioned waterproof casing at mud face, filled by lifting
Put lifting, and realize towage migration, reach the purpose thrown aside, after platform enters dock, by taking out internal penetration pile, can achieve weight
Multiple utilization.
Due to taking above technical scheme, it has following excellent self installation wellhead platform with mat proposed by the present invention
Point:
1st, platform can be in place with self installation；The present invention utilizes lowering or hoisting gear to can achieve to bottom mat and main platform body
Control, realize the installation to platform under the buoyancy of bottom mat and main platform body it is not necessary to employ crane barge resource.
2nd, multiple well heads can be arranged in bank, more than such as at least 50 mouthfuls wells, can meet the exploitation of shallow water large oilfield；
3rd, platform lower is provided with mat, can play platform antidumping effect that is anti-settling and increasing platform stabilization；
4th, platform upper structure is hull form, can meet stability during towage and require；
5th, waterproof casing is guided by platform well mouth area and mat guiding is connected, and stability is preferable；
6th, in towage, the penetration pile with certain length in spud leg is it is ensured that completed with small-sized crane barge after in place for platform
Piling work, cost saving.
