The utility model can substitute a floating production system to develop the offshore oil in the deep sea, basically avoid the ice force, the wind wave force, and the like suffered by the floating production system and greatly avoid the production halts in order to take shelter from the wind.
Description
Technical field:
The utility model belongs to the ocean engineering field, develops a kind of device of oil storage Petroleum Production under water that is used for deep water.
Technical background:
Traditional oil storage production system mainly contains floating production system, semi-submersible type production platform in the deep-sea oil exploitation, all belongs to floating oil storage production model.The Floating Production pattern can be considered as mature technology in the world, has many superiority, but owing to be subjected to the great force of marine stormy waves, no matter be that offshore structure or its lashing system cost are high, and along with the increase of the depth of water, technical difficulty is more and more higher, and the facility cost sharply raises.In seabed, oil field, deep-sea, wind wave action almost can be ignored, under the prerequisite that solves oil gas primary treatment problem under the high undersea hydrostatic pressures condition, and the defeated pattern of the collection effective way of can yet be regarded as under water.Oil storage technology under water has the precedent of successful Application in the marine site (depth of water is generally in 150m) that is suitable for gravity platform, jack-up unit, mainly contains gravity platform oil storage under water and oil and water displacement oil storage dual mode under water, but does not appear in the newspapers at the deep-sea." Petroleum Production safeguards system under water " (200520083519.7) that our unit declares also adopt oil storage under water, and its production model is only applicable to the shallow sea.
Summary of the invention:
The utility model indication deep-sea is meant that the surface unit of selecting usually that is difficult to use fixed jacket platform because of the depth of water is excessive carries out the zone of oil gas drilling.
The purpose of this utility model is a kind of deepwater underwater oil-storage petroleum production device of exploitation, can replace floating oil storage production system to carry out the deep-sea oil exploitation.
Deepwater underwater oil-storage petroleum production device described in the utility model, whole system comprise underwater well head module, processing module, oil and water displacement oil storage module under water, deep water standpipe, lashing or dynamic positioning device, floating drum, shuttle tanker under water;
Feature of the present utility model is the underwater well head module of described deepwater underwater oil-storage petroleum production device, processing module, oil and water displacement oil storage module under water all are positioned at the seabed and are serially connected under water; Small-sized floating drum floats on the surface, and locatees with lashing mooring location or with the dynamic positioning device, and deep water standpipe one end is connected with oil storage module under water, and the other end links to each other with floating drum; Mooring is on floating drum when charge of oil for shuttle tanker, and oil storage module under water is to falling oily by the deep water standpipe and the water surface to shuttle tanker with upper pipeline; It is the shuttle tanker mooring that floating drum mainly acts on.
The utlity model has following advantage:
(1) the utility model is compared with floating oil storage production system, and oil storage under water can be avoided ice power, the effect of stormy waves power substantially, and oil storage modular structure requirement of strength is low, possesses movably advantage simultaneously.
(2) oil storage storage tank inside and outside differential pressure is little under water for oil and water displacement, needn't consider whole problem of withstand voltage, and structural strength requires low, and system cost can not increase sharply rising with the depth of water.
(3) the utility model floating drum does not have the oil storage effect, and suffered stormy waves power etc. act on much smaller than huge floating oil storage system, needn't wind sheltering withdraw, and needn't close a well under the enough prerequisite of oil storage capacity.
(4) the utility model water surface is little with top, and anchoring system can adopt simple lashing or lower-powered dynamic positioning, need not to adopt expensive turret mooring system, and cost can significantly reduce.
(5) be full of liquid in the utility model oil and water displacement oil storage module under water always, can avoid oil storage waterborne ubiquitous " oil gas breathing " loss, reduced atmosphere pollution, reduced firing risk.

1, underwater well head module 2, processing module 3, oil and water displacement oil storage module under water 4, deep water standpipe 5, lashing 6, floating drum 7, shuttle tanker 8, dynamic positioning device under water
The specific embodiment:
Now, the utility model is further described in conjunction with Figure of description 1 and 2:
Deepwater underwater oil-storage petroleum production device, whole system comprise underwater well head module 1, processing module 2, oil and water displacement oil storage module under water 3, deep water standpipe 4, lashing 5 or dynamic positioning device 8, floating drum 6, shuttle tanker 7 under water; Underwater well head module 1, processing module 2, oil and water displacement oil storage module under water 3 all are positioned at the seabed and are serially connected under water; Floating drum 6 floats on the surface, and with lashing 5 or dynamic positioning device 8 location, deep water standpipe 4 one ends are connected with oil storage module under water 3, and the other end links to each other with floating drum 6; Shuttle tanker 7 when charge of oil mooring on floating drum 6.
Consider cost and technical problem, when the depth of water during greater than 1500m, the ocean engineering field is generally no longer used lashing and is located large-scale buoyancy aid at present.In same reason the utility model,, during greater than 500m, recommend to adopt the dynamic positioning mode in the depth of water because floating drum is less.
Consider application, the capacity of oil storage module should be not less than 10000 sides.
After each module is made respectively and finished, finish on-the-spot installation down in that engineering ship such as crane barge and underwater robot are auxiliary.The oil storage module 3, other module is installed existing maturation process under the profit replacing water.
Oil and water displacement oil storage module under water 3 is because volume is big, weight is big, and offshore installation method is recommended as follows: oil and water displacement oil storage module under water 3 is installed preferably 2 barges, and every barge is provided with 2 winches and 1 high-pressure aerated pump.Oil and water displacement oil storage module under water 3 is provided with kingston valve, hanger and loading line, self possesses enough buoyancy.Towage is connected to winch cable on the hanger of oil storage module 3 to the precalculated position, opens kingston valve, and oil storage module 3 water inlet is sunk, and during the complete entry of oil storage module 3, buoyancy and gravity are in a basic balance, control the winch lowering velocity, and oil storage module 3 is steadily transferred.In the sinking process, water pressure constantly increases the air that makes in the oil storage module 3 and is compressed, and buoyancy reduces.If it is enough that winch draws high ability, there is no need inflatable drainage, otherwise inflatable drainage gradually, with compensation buoyancy.
Consider the restriction of large-scale underwater structures erection equipment, can consider to form the underwater oil storage tank group with a plurality of submerged storage tanks.
At the ordinary production state, the fluid that underwater well head module 1 is produced enters under water processing module 2 to be separated under water, isolated crude oil input oil and water displacement oil storage module under water 3 stores, isolated water is through re-injection manifold re-injection or row up to standard sea, and the gas that sub-argument goes out is transported to burning on the floating drum 6 through deep-sea standpipe 4 (or establishing pipeline in addition).Crude oil in the oil and water displacement oil storage module under water 3 is transported on the sea through deep-sea standpipe 4, is shipped on the shuttle tanker 7 and pulls away.Mooring is on floating drum 6 during the shuttle tanker charge of oil.
