Description
Technical field:
The utility model is related to a kind of ocean deepwater technical field of operation, more particularly to one kind being applied to semi-submersible type drilling well and putting down
The device of platform.
Background technology:
Wide ocean is richly stored with petroleum resources, is exploited from offshore waters with marine oil and gas and has evolved to depth
Saline waters, the platforms such as traditional jacket and gravity type are not suitable for abyssalpelagic due to dead weight and the significantly increase of cost
Oil-gas mining.In recent decades, by the research to novel ocean platform, with tension leg platform (TLP) (TLP), float-type platform
(SPAR), the flat forms such as semisubmersible platform (SEMI), floating vessel type (FPSO) are exploited suitable for deep-sea oil gas, operate mainly in ink
The deep sea waters such as Xi Gewan, Brazil, West Africa, the North Sea.
Compared with TLP and SPAR, semisubmersible platform has gross investment relatively fewer, and deck possesses the space of bigger and can
Changing load is born, there is stronger production capacity, the operating depth range of bigger, be easy to be transformed and have drilling well, well workover, life
A variety of work functions such as production, are not necessarily to Attention problems, the round-the-clock ability to work in the whole world and the advantages of deposit ability etc. certainly.It is based on
Many-sided comprehensive considerations such as cost of investment, operating depth range, well head number, the length of service and work region, semisubmersible platform
It is a kind of drilling platforms for being relatively specific for deep sea waters exploitation petroleum resources.
Semisubmersible drilling platform is a kind of deep sea drilling platform being widely used, capacity of anti-storm in worldwide
It is suitable for ocean deepwater operation by force.Existing semisubmersible platform provides buoyancy by two buoyancy tanks for platform, and each buoyancy tank supports
Two vertical columns, the apical support deck of column, the drilling platforms of this structure during the work time, the drinking water of platform compared with
Shallow, rolling and pitching amplitude are smaller, but the amplitude of heaving is larger, and the stability of platform is destroyed, in heaving
In this way under the action of cyclic loading, the standpipe of ocean platform is also susceptible to fatigue damage.Therefore, inhibit semisubmersible platform heaving
The technique study of movement has important engineering background and practical significance.
Research shows that being equipped with heave plate below semisubmersible platform, the heaving of platform can be inhibited.Heave plate is also deposited
Inhibit the effect of heaving different in the heave plate of different form, each form, traditional heave plate is generally fixedly connected
Under platform below floating body, there is different form, the heave plates of each form to inhibit the effect of heaving different for heave plate,
The heaving under working platform state is alleviated to some extent.
But semisubmersible platform, under towing condition, the strong incoming of towage causes vortex to be detached from, and generates the liter of periodic vibration
With certain frequency and amplitude vibration, i.e., force effect makes to be in underwater column and heaving plate truss structure under lift effect
The phenomenon that producing vortex-induced vibration, this phenomenon can make semisubmersible platform be in underwater structure and standpipe by larger alternation
Stress, so that generating fatigue damage.Meanwhile heave plate below semisubmersible platform floating body and lattice supporting framework are immersed in
In seawater, larger towage resistance is easy tod produce, towage resistance will be to the operation timeliness of semisubmersible platform and fuel consumption etc.
Aspect has an impact.
