Abstract

The utility model relates to an oil-storage mat-type concrete production platform in a shallow sea, consisting of a mat, upright columns and a deck, wherein the mat is provided with four cylinder-shaped parts in the concrete structure; a precast slab in the concrete structure is connected between cylinders; a cavity in the cylinder is an oil storage tank and is internally provided with a diaphragm; four cone-shaped parts in the concrete structure are respectively arranged at the tops of the four cylinder-shaped parts in the concrete structure; the upright columns are four parts in the reinforced concrete structure; the bottom ends of the four upright columns respectively penetrate through from the center of the end face of the four cone-shaped parts in the concrete structure and are fixed on the cone-shaped parts in the concrete structure; the deck is a part in the reinforced concrete structure; the bottom surface of the deck is fixed on the top ends of the four upright columns; diagonal support decks are arranged between the deck and the upright columns; an apron board is arranged below the mat; and the cylinder-shaped mat adopts the concrete structure, therefore the corrosion resistance is reinforced, the platform can be reused, the development cost of the shallow sea is lowered, and the oil-storage mat-type concrete production platform is applicable to the production operation of the oil field at the margin of the shallow sea.

Description

But a kind of shallow sea oil storage settling type concrete production platform

Technical field

The utility model relates to a kind of ocean platform, but shallow sea area oil storage settling type concrete production platform particularly.

Background technology

Oil field, shallow sea, beach is the important growth point of operational oil development on the China sea, and up to the present, China's ring Bohai Sea Tan Hai oilfield prospecting developing mainly relies on steel platform, is obtaining a lot of successful experiences aspect design, construction, construction and the use of steel platform.But steel platform exists, and steel quantity consumption is big, cost is high, the maintenance than shortcomings such as difficulties.

Concrete platform is safe and reliable technically, and has the ability of stronger anti-seawater corrosion, antifatigue and anti-accident load than the steel platform.Advantages such as in addition, it is many that concrete platform also has function, safeguards simply, and the safe in utilization and life-span is long, and can reuse, can effectively save investment, increase the economic feasibility of the exploitation of marginal oil field, hew out one new road for the shallow sea oil field development.

The utility model content

The purpose of this utility model is at the shallow sea marine petroleum development, but a kind of oil storage settling type concrete production platform that provides can effectively reduce shallow sea marginal oil field cost.

But a kind of shallow sea oil storage settling type concrete platform described in the utility model is made of heavy pad, column and deck; Heavy pad is the circle tube member of four concrete structures, precast plate by concrete structure between cylinder and the cylinder is connected, the tube internal cavity is an oil storage chamber, in establish dividing plate, the cone shape member of four concrete structures lays respectively at the circle tube member top of four concrete structures, column is the member of four reinforced concrete structures, four root post bottoms penetrate from the cone shape member end face center of four concrete structures respectively, be fixed on the cone shape member of concrete structure, the deck is the member of reinforced concrete structure, the bottom surface, deck is fixed on the four root post tops, by the diagonal brace support deck, under the heavy pad skirtboard can be set between deck and the column.

The present invention adopts above design, mainly has the following advantages:

1, the concrete platform cost is low, and maintenance cost is economized, and has good antifatigue, shock resistance, anti-seawater corrosion ability, good endurance.

2, the heavy pad of cylindrical shape of the present invention oil storage chamber can be brought into play the oil storage function during operation.

3, adopt tapered structure to be connected between the heavy pad of cylindrical shape and column, can reduce the platform water plane area to reduce the suffered seaway load of platform, pyramidal structure can also increase an end stability of platform as ballast tank in addition.

4, column of the present invention and Texas deck adopt the reinforced concrete structure pattern, effectively strengthen platform intensity, can realize the multifunction of producing.
