Abstract
The utility model relates to a gravity type underwater oil storage platform suitable for shallow sea, which is used for underwater oil storage for the shallow sea. The gravity type underwater oil storage platform mainly comprises a reinforced concrete tank body, steel upright columns, a platform deck, an oil delivery pipeline, an oil-well pump unit and a bucket foundation; the reinforced concrete tank body is welded into a whole with the platform deck through the steel upright columns; the inversely buckled bucket foundation is arranged at the lower part of the reinforced concrete tank body; the oil-well pump unit, an oil inlet pipeline and an oil outlet pipeline are installed in the reinforced concrete tank body respectively; one end of the oil outlet pipeline is connected with the oil-well pump unit; and both the oil inlet pipeline and the oil outlet pipeline are connected to the upper part of the deck. The bucket foundation penetrates into soil to increase the bearing capacity of the platform, and the produced crude oil is stored in the reinforced concrete tank body after processed and then is periodically carried away by an oil tanker, so that the purpose of offshore underwater oil storage can be achieved, and the development cost of oil in the shallow sea can be reduced.
Description
Technical field:
The utility model belongs to a kind of novel oil storage platform under water of shallow sea petroleum development.
Technical background:
China's shallow sea petroleum development scale is comparatively fast developed at present, the Bohai Sea, the South Sea, the East Sea are through exploration for many years, a plurality of oil gas fields have been found in succession, they take over resource as the strategy of east China oil, step up exploitation, must need the many offshore oil productions of design-build, oil storage equipment accordingly.China shallow sea petroleum development adopts that the pipeline collection is defeated, standing tank platform or individual well be by the ship mode of production, and development cost is higher.
Have the platform of steel concrete for the basis abroad, the steel concrete production platform in wherein Brazilian Wu Bana oil field is based on oil storage tank, and oil storage capacity is up to 23000 cubic metres.Reinforced concrete platform is the gravity platform of shallow foundation, not only can save construction costs, and can significantly improve the stability of production platform.
The movable barrel base platform technology is comparative maturity, has had the advantage of fixed platform and moveable platform concurrently, is fit to very much the shallow sea Oilfield developing.
There is the saving of adopting that development of new is badly in need of in the territory, ice formation to be equipped with in the shallow sea, reduces shallow sea oil field development cost.
Summary of the invention:
The utility model is studied a kind of novel shallow sea gravity oil storage platform under water, reduces shallow sea oil field development cost.The purpose of this utility model is a kind of gravity that is applicable to the shallow sea of exploitation oil storage platform under water.
A kind of gravity that is applicable to the shallow sea is oil storage platform under water, mainly form by steel concrete tank body, steel column, Texas deck, petroleum pipeline, oil well pump group, barrel base, steel concrete tank body and Platform Deck are welded into as a whole by the steel column, steel concrete tank body bottom is provided with the barrel base of back-off type, oil well pump group, feed line and flow line are installed in the steel concrete tank body, one end of flow line is connected with the oil well pump group, and feed line and flow line all are connected to the top on deck.
This novel platform tool has following advantage:
(1) oil storage replaces the oil storage of Platform Deck storage tank under the concrete tank water, can significantly reduce the suffered upper load of platform, increases the safety of platform;
(2) the Water Plane place adopts steel change diameter column to reduce Water Plane, reduces ice, unrestrained environmental load, can reduce the structural meterials consumption;
(3) barrel base relies on deadweight and suction suction penetration to go into mud, need not the marine guidance piling operation, and is convenient to extract displacement and platform recycling, can save the marine set-up time, reduces shallow sea oil field development cost, protects the marine environment.

4, feed line 5, flow line 6, barrel base
The specific embodiment:
Now, the utility model is further described in conjunction with Figure of description:
Make steel concrete tank body 1 (steel concrete tank body 1 bottom is provided with the barrel base 6 of back-off type), Platform Deck 3 and steel column 2 respectively according to designing requirement; At steel concrete tank body 1 top welding steel column 2; Platform Deck 3 and steel column 2 are welded together, and steel concrete tank body 1, Platform Deck 3 are as a whole with 2 one-tenth on steel column like this; Oil well pump group 7, feed line 4 and flow line 5 are installed in steel concrete tank body 1, and an end of flow line 5 is connected with oil well pump group 7, and feed line 4 and flow line 5 all are connected to the top on deck 3.
After construction is finished, platform is dragged to pre-Dinghai District well location, relies on that gravity is heavy and passes through (if necessary, cooperate the negative pressure suction is heavy passes through) to make barrel base 6 go into mud fully, increase the supporting capacity (especially anti-incline, anti-slide performance) of platform.
The crude oil of producing enters in the steel concrete tank body 1 by feed line 4 after treatment and stores; According to the oil reserve setting value, shuttle tanker regularly draws oil, starts oil well pump group 7, by flow line 5 crude oil that stores in the steel concrete tank body 1 is transported to shuttle tanker, realizes producing continuously.
During according to the displacement of exploitation situation needs, barrel base 6 is extracted in gas injection in steel concrete tank body 1, barrel base 6, and platform is floating, and towage is displaced to new sea area well location.
This device is suitable for the oil storage under water of shallow sea petroleum development, and is convenient to the displacement recycling, can reduce shallow sea oil field development cost.
