Abstract

A bottom-supported production storage platform comprises a lower-floating-body bottom buoyancy tank, a plurality of lower-floating-body uprights and upper blocks, wherein the lower-floating-body uprights are mounted on the lower-floating-body bottom buoyancy tank; the upper blocks are mounted on the plurality of lower-floating-body uprights; hollow steel watertight upright inner shells are mounted within the lower-floating-body uprights so that the lower-floating-body uprights become crude oil tanks having double-layer shell structures and used for storing oil; and watertight cabins formed between the upright inner shells and upright outer shells are upright ballast tanks, which are used for separating seawater and protecting the crude oil tanks. The invention can realize oil storage, transferable and self-mounting capabilities without a special lifting device; therefore, the input cost of this part is greatly saved, the bottom-supported production storage platform can operate under environments with serious ice conditions, realizes very high ice resistance, greatly increases the working efficiency and reduces oilfield development cost.

Description

Bottom-sitting type produces oil storage platform

Technical field

The present invention relates to oil storage platform, particularly relate to a kind of bottom-sitting type shallower for the depth of water, marginal oil field that reserves are less and produce oil storage platform.Belong to field of ocean engineering.

Background technology

At present, for small-sized without the exploitation relying on oil field, the pattern of industry comparative maturity is the pattern of " wellhead installation+production Fuel Tanking Unit+export tanker ".Wherein, producing Fuel Tanking Unit and mainly adopt jack up to produce oil storage platform, be characterized in the spud leg that can be freely lifted, platform possesses transportable and self installation ability.But, this kind of jack up produces oil storage platform and there is problems in that

1) lowering or hoisting gear buying expenses is higher, and also needs during use to put into maintenance cost, considerably increases oil field development cost, and economy is poor.

2) jack-up unit anti-ice ability is poor, need to withdraw in time when ice condition is serious, and otherwise platform has risk of toppling.

Summary of the invention

Present invention is primarily targeted at the disadvantages mentioned above overcoming prior art to exist, and provide a kind of bottom-sitting type to produce oil storage platform, it just possesses without special lowering or hoisting gear and has oil storage, transportable and self installation ability, is not only greatly saved the Meteorological of this part;And, it can carry out operation under the environment that ice condition is serious, has very strong anti-ice ability, substantially increases work efficiency, reduces oil field development cost.

It is an object of the invention to be realized by techniques below scheme:

A kind of bottom-sitting type produces oil storage platform; it is characterized in that: including: buoyancy tank bottom lower buoyancy aid, be arranged on bottom lower buoyancy aid the several lower buoyancy aid column above buoyancy tank, be arranged on the upper chunk above several lower buoyancy aid column; wherein; an internally installed hollow type steel watertight column inner shell of lower buoyancy aid column; make lower buoyancy aid column become the crude oil tank for oil storage of double-layer shell structure, and the watertight cabin between column inner shell and column shell is: for the column ballast tank of insulating sea water, protection crude oil tank.

Described upper chunk is divided into according to function: process handling module, main electrical power plant module, shared device module and four modules of accommodation module, is connected into as a whole between these four modules by trestle.

Bottom described lower buoyancy aid, buoyancy tank is " returning " font, and several lower buoyancy aid columns are separately mounted to the corner of buoyancy tank bottom lower buoyancy aid;Meanwhile, bottom lower buoyancy aid, buoyancy tank is bottom ballast tank, and bottom this, ballast tank is separated into several cabin.

The top area of described several lower buoyancy aid column separates sedimentation cabin, begin to rehearse filling cabin, diesel oil tank, fresh-water tank, sky cabin and the several cabin of stowing, water place, and several cabins are mutually isolated with crude oil tank.

Beneficial effects of the present invention: due to the fact that employing technique scheme, it just possesses without special lowering or hoisting gear oil storage, transportable and self installation ability, is not only greatly saved the Meteorological of this part;And, it can carry out operation under the environment that ice condition is serious, has very strong anti-ice ability, substantially increases work efficiency, reduces oil field development cost.

Detailed description of the invention

As shown in Fig. 1 Fig. 3, the present invention includes: buoyancy tank 3 bottom lower buoyancy aid, adopt welding manner to be arranged on the above several lower buoyancy aid column 2 of buoyancy tank 3 bottom lower buoyancy aid, adopt welding manner to be arranged on several lower buoyancy aid column 2 upper chunk 1 above, wherein, the inside of lower buoyancy aid column 2 adopts welding manner to install the diameter hollow type steel watertight column inner shell 14 less than column shell 13, lower buoyancy aid column 2 is made to become the crude oil tank 5 of double-layer shell structure, crude oil tank 5 is cylindrical watertight cabin, for oil storage;And the watertight cabin between column inner shell 14 and column shell 13 is: column ballast tank 6;So, column ballast tank 6 serves the effect of insulation blocking between crude oil tank 5 and outside sea water.

Above-mentioned upper chunk 1 is divided into four independent little modules according to function, respectively process handling module 15, main electrical power plant module 16, shared device module 17 and accommodation module 18, then, will connect into as a whole by trestle 19 between these four modules.

Bottom above-mentioned lower buoyancy aid, buoyancy tank 3 is in " returning " font, and several lower buoyancy aid columns 2 (the present embodiment is four) are separately mounted to the corner of buoyancy tank 3 bottom lower buoyancy aid;Meanwhile, bottom lower buoyancy aid, buoyancy tank 3 is bottom ballast tank 4, and bottom this, ballast tank 4 is installed steel bulkhead by welding manner and is divided into several cabin, to reduce the free surface adverse effect to stability.

The top area of above-mentioned several lower buoyancy aid column 2 is separated out several watertight cabin by welding steel bulkhead mode, several watertight cabins are respectively as follows: sedimentation cabin 7, beginning to rehearse fills cabin 8, diesel oil tank 9, fresh-water tank 10, empty cabin 11, water place stowing 12 etc., and mutually isolated with crude oil tank 5.

The above, it it is only presently preferred embodiments of the present invention, not the present invention is done any pro forma restriction, every any simple modification, equivalent variations and modification above example made according to the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
