Abstract
A submarine pipeline bundle suitable for offshore oil field exploitation is applied to submarine oil delivery in submarine oil field exploitation and comprises an outer pipe, two oil-gas mixed delivery pipes, a water injection pipe and two cables. An anti-corrosion coating layer is arranged on the outer wall of the outer pipe, the two parallel oil-gas mixed delivery pipes are arranged in the outer pipe, the outer walls of the oil-gas mixed delivery pipe are provided with insulation layers, the water injection pipe parallel to the oil-gas mixed delivery pipes is arranged in the outer pipe, and the two cables parallel to the oil-gas mixed delivery pipes are arranged in the outer pipe. The submarine pipeline bundle suitable for offshore oil field exploitation has the advantages of being excellent in insulation performance, simple in installation, low in cost and capable of providing mechanical protection to multiple oil delivery pipelines and cables.
Description
Technical field
The utility model relates to submarine pipeline oil transportation technical field, is used for the pipeline of submarine oil-transportation in particularly a kind of offshore oil field exploitation, is a kind of seabed boundling pipeline of many petroleum pipeline boundlings in a pipeline with insulation, corrosivity.
Background technique
The pipeline under the ocean equipment that is absolutely necessary in marine oil gas field exploitation is mainly born oil field transferring oil, gas and is carried the stratum to inject functions such as water.At present, the submarine pipeline of China's offshore oilfield application mainly contains two kinds: a kind of is two-layer pipe, and a kind of is the mono-layer tube structure.Owing to particular job environment of marine petroleum exploitation, brought the insulation difficult problem of submarine pipeline; Submerged pipeline also might be subjected to weigh down thing and the fisherman injury such as cast anchor of casting net during operation; The pipe laying barge rent of present domestic specialty is expensive, can't construct at some utmost point neritic zone; In this external offshore oil field exploitation, lay pipelines such as a large amount of oil transportations, gas transmission, water filling, inevitably produce crowded and intersection.
The model utility content
The purpose of this utility model is: the seabed of using in a kind of suitable offshore oil field development boundling pipeline is provided, once finishes the sea of many pipelines and install, simplify submarine pipeline and install, save mounting cost; The thermal insulation property of economic high-quality is provided simultaneously, is applicable to and carries high sticking, the high crude oil that coagulates characteristic.
The technical solution adopted in the utility model is: be suitable for the seabed boundling pipeline that uses in the offshore oil field development, comprise outer tube, oil and gas multiphase flow pipe, water injecting pipe and cable, at the outer wall of outer tube corrosion-inhibiting coating is arranged.It is characterized in that: two parallel oil and gas multiphase flow pipes are arranged in outer tube, thermal insulation layer is arranged at oil and gas multiphase flow pipe outer wall.A water injecting pipe that is parallel to the oil and gas multiphase flow pipe is arranged in outer tube; Two cables that are parallel to the oil and gas multiphase flow pipe are arranged in outer tube.
The external diameter of its middle external tube is at 400～1100mm; The external diameter of oil and gas multiphase flow pipe is between 190～490mm; The external diameter of water injecting pipe is between 100～200mm.The external diameter of cable generates needs according to reality can do change; The material of thermal insulation layer adopts the employed soft thermal insulating material of continental line.
Oil and gas multiphase flow pipe in the outer tube, water injecting pipe and cable symmetry are placed.
The manufacture process that summary is suitable for the seabed boundling pipeline that uses in the offshore oil field development is as follows:
Seabed boundling pipeline production site often is provided with the welding shop that a sealing is moved.Before prefabricated, the 12m that each single steel pipe length is standard, and its outer surface scribbles the multi-layer anticorrosion coating.The welding zone is all left at the two ends of every pipe, and the welding zone does not have corrosion-inhibiting coating, to satisfy requirement of welding, finishes welding back coating corrosion-inhibiting coating.In welding shop, at first with the outer tube welding forming, single steel pipe is welded into process duct branch line group, through non-destructive inspection, carry out boundling with cable, pass through outer tube, carry out the welding of branch line group then, repeat non-destructive inspection; Carry out boundling with cable, and pass through outer tube, finally be welded into the length of requirement.At last, it is transported to bank integral body carries out hydraulic pressure test, prepare marine the installation.
The beneficial effects of the utility model: the utility model is suitable for the seabed boundling pipeline that uses in the offshore oil field development, because the existence of outer tube, make the boundling pipe interior form the space of hermetically drying, outer wall energy at the oil and gas multiphase flow pipe is used the thermal insulating material that can't use in the seabed, reduce engineering cost, can improve the thermal insulation property of oil and gas multiphase flow pipe again.Because the existence of outer tube, provide protection to the pipeline and the cable of inside, avoid because pipeline destroys the problems such as environment and production that exert an influence, thereby guarantee that pipeline is long-term, safe operation.Because seabed boundling pipeline is with the pipeline boundling of many different purposes together, can use that low-cost tugboat is disposable finishes marine the installation, need not to rent high pipe laying barge, a series of problems of having avoided the submerged pipeline intersection simultaneously and having crowded and bring.
