The valve can be operated by an underwater robot, and the operability of the underwater manifold package is improved effectively. The novel underwater manifold package is simple in structure, practical and effective, and suitable for the needs of deep sea development.
Description
Technical field
The utility model relates to a kind of underwater manifold sledge.
Background technology
The subsea manifold sledge is one of critical facility of subsea production system, and its invention, exploitation have very great meaning to the exploitation in deep water hydrocarbon field.There is following shortcoming in subsea manifold sledge commonly used at present: 1, without the pigging function.Existing manifold sledge does not generally design wiper interface under water, and wiper can't be connected the pigging operation of serving a ball with the subsea manifold sledge, therefore may cause the inner greasy dirt of submerged pipeline to deposit, thus to pipeline result in blockage, the risk of corrosion and environment pollution; 2, without the isolation detection function.When subsea production system relates to two or more wellblock, brill completion practice, production time such as each wellblock are inconsistent, then need the oil gas of two wellblocks is kept apart with valve, existing subsea manifold sledge can't be isolated the production of each wellblock, more has no idea to detect the valve isolation effect.Oil gas such as the wellblock of going into operation first enters other wellblocks, then the safety of other wellblocks is produced great risk.3, valve can not be realized the underwater robot operation.Adopt the saturation diving operation, one, the operation sea situation is limited, and needs the support of proprietary dynamic positioning boats and ships; Its two, operating efficiency is lower, and has higher security risk.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that subsea manifold sledge commonly used exists, and a kind of novel manifold sledge that has pigging function, isolation detection function and can realize the underwater robot operated valve is provided.
The utility model is by supervisor, supervisor supports, arm, arm supports, understructure, reducing tee, adpting flange, bend pipe, the submarine pipeline connector, wiper under water, all flanged tee, valve and blind flange form, supervisor and arm support by supervisor respectively and arm is supported and fixed on the manifold sledge understructure, arm is by reducing tee access supervisor, supervisor's horizontal segment end is connected with bend pipe by adpting flange, bend pipe changes into the pipeline direction vertically by level, at its end the pigging interface is set, it is the submarine pipeline connector, the submarine pipeline connector is connected with wiper under water, wiper is dismountable under water, connect under water blind plate on the pipe jointer with its shutoff, arrange one with all flanged tee of valve at supervisor's horizontal segment initiating terminal, all flanged tee links to each other with valve, can be connected with blind flange.
The utility model can be installed as required under water wiper by the submarine pipeline connector and realize pigging function under water; By the separation valve door on the Trunk Line and can isolate safely the production of two wellblocks with all flanged tee of isolating valve, and can realize the detection to production status.Valve can be realized underwater robot operation, Effective Raise the operability of subsea manifold sledge.Simple in structure, practicability and effectiveness, the needs of suitable ocean petroleum developing.
Description of drawings
Fig. 1 is the utility model organigram.
1. supervisors among the figure, 2. supervisor supports, 3. arm, 4. arm supports, 5. understructure, 6. reducing tee, 7. adpting flange, 8. bend pipe, 9. submarine pipeline connector, 10. wiper under water, 11. all flanged tees, 12. valves, 13. blind flanges.
The specific embodiment
As shown in Figure 1, the supervisor 1 on the subsea manifold sledge and arm 3 support the 2 and second arm support 4 by the first supervisor respectively and are fixed on the manifold sledge understructure 5, and arm 3 is by reducing tee 6 access supervisors 1.
Being responsible for the terminal adpting flange 7 that passes through of 1 horizontal segment is connected with bend pipe 8, bend pipe 8 changes into the pipeline direction vertically by level, at its end submarine pipeline connector 9 is set, submarine pipeline connector 9 is connected with wiper 10 under water, sends spherical pigs by wiper 10 under water and can carry out pigging operation; In the time pigging operation need not being carried out, can with wiper 10 dismountings under water, connect under water blind plate on the pipe jointer 9 with its shutoff.
Arrange one with all flanged tee 11 of valve at supervisor's 1 horizontal segment initiating terminal, in the time need not carrying out the isolating seal detection, the valve 12 of all flanged tee 11 is closed, blind flange 13 connects; When needs carry out the isolating seal detection, the valve 12 of all flanged tee 11 to be opened, blind flange 13 unloads.
Be reserved with wiper interface under water at supervisor's 1 line end, i.e. submarine pipeline connector when not carrying out pigging operation, connects under water blind plate and carries out shutoff on the pipe jointer 9.When carrying out pigging operation such as need, the blind plate of lifting submarine pipeline connector under the assistance of robot under water, and wiper 10 is fixed together with submarine pipeline connector 9 under water, again will transfer and rely on submarine pipeline connector and subsea manifold locking with the wiper under water 10 of submarine pipeline connector under the assistance of robot under water.Because wiper 10 has been pre-installed a plurality of spherical pigs on the water surface under water, can realize under water by different interval requirement emission spherical pig.
Supervisor's 1 line design, latus rectum is installed valve realizing the isolation of two wellblocks that different time can be produced respectively, moreover at all flanged tee 11 of Trunk Line design, mounting strap isolating valve, so that the installation and measuring element.Need to produce simultaneously such as two wellblocks, namely open the isolating valve on the Trunk Line.As two wellblocks not at the same time the phase produce, can be by installation and measuring element on all flanged tee of isolating valve in order to detect the isolation situation of production wellblock and nonproductive wellblock.
Owing on all valves of manifold sledge the underwater robot operation-interface being installed all under water, all valves on the subsea manifold sledge of the present utility model all can be realized the underwater robot operation.
By the submarine pipeline connector wiper can be installed as required under water and realize pigging function under water; By being responsible for the separation valve door on 1 line and can isolating safely the production of two wellblocks with all flanged tee 11 of isolating valve, and can realize the detection to production status.Valve on the subsea manifold sledge can be realized underwater robot operation, Effective Raise the operability of subsea manifold sledge.Simple in structure, practicability and effectiveness, the needs of suitable ocean petroleum developing.
