Description
Technical field
The utility model belongs to sea oil drilling and production equipment technology field, relates to a kind of underwater horizontal type X-tree detective pole.
Background technology
In offshore oil exploration and exploitation process, underwater horizontal type X-tree is one of critical equipment.Underwater horizontal type X-tree is that one is arranged on underwater horizontal type X-tree bottom with detective pole, for carrying out the device of pressure test to it.
Existing underwater horizontal type X-tree is more single by detective pole version, and often kind of underwater horizontal type X-tree detective pole can only be applicable to a kind of underwater horizontal type X-tree.If when needing to carry out pressure test to another underwater horizontal type X-tree, then need to design the underwater horizontal type X-tree detective pole matched, this just makes underwater horizontal type X-tree detective pole lack versatility, can not realize one multiplex, reduce the versatility service efficiency of underwater horizontal type X-tree detective pole.
Utility model content
The purpose of this utility model is to provide a kind of underwater horizontal type X-tree detective pole, solves existing underwater horizontal type X-tree detective pole version single, the problem of poor universality.
The technical scheme that the utility model adopts is, a kind of underwater horizontal type X-tree detective pole, comprise detective pole body, detective pole body lower end is fixedly connected with detective pole base, the inwall carrying step of detective pole body is sat and is placed with test cartridge, between test cartridge and detective pole body, be fixedly connected with set bolt;
Test cartridge inwall step is sat and is placed with test blocking, the axle center hole of test blocking is externally communicated with needle-valve by hydraulic line, needle-valve and dividing plate fittings.
Underwater horizontal type X-tree detective pole of the present utility model, its feature is also:
Surface of contact between detective pole body and test cartridge is provided with sealing II, and the surface of contact between test blocking and test cartridge is provided with sealing I.
The beneficial effects of the utility model are, by only changing test cartridge and the test blocking of underwater horizontal type X-tree detective pole inside, pressure test can be carried out to dissimilar underwater horizontal type X-tree, one that achieves underwater horizontal type X-tree detective pole multiplex, improve its versatility service efficiency, structure is simple, easy to operate, can meet the requirement of underwater horizontal type X-tree pressure test completely.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model underwater horizontal type X-tree detective pole.
In figure, 1. detective pole body, 2. test cartridge, 3. set bolt, 4. test blocking, 5. securing member, 6. detective pole base, 7. hydraulic line, 8. seal I, 9. seals II, 10. needle-valve, 11. dividing plate joints.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, structure of the present utility model is, comprise detective pole body 1, detective pole body 1 lower end is fixedly connected with detective pole base 6 by securing member 5, the inwall carrying step of detective pole body 1 is sat and is placed with test cartridge 2, between test cartridge 2 and detective pole body 1, be fixedly connected with set bolt 3;
Test cartridge 2 inwall step is sat and is placed with test blocking 4, the axle center hole of test blocking 4 is externally communicated with needle-valve 10 by hydraulic line 7, and needle-valve 10 is communicated with dividing plate joint 11;
Surface of contact between detective pole body 1 and test cartridge 2 is provided with sealing II 9, and the surface of contact between test blocking 4 and test cartridge 2 is provided with sealing I 8.
Detective pole base 6 is welded by various structural steel, supports detective pole body 1.
Hydraulic line 7, needle-valve 10 and dividing plate joint 11 constitute the pressure test of underwater horizontal type X-tree detective pole and inject/discharge system.Dividing plate joint 11 is fixedly connected with detective pole base 6 by the circular hole on detective pole base 6, and needle-valve 10 is fixedly connected with detective pole base 6 by screw.
Detective pole body 1 upper end adopts general locking profile (as H4 profile), and underwater horizontal type X-tree locks on detective pole body 1 top by the hydraulic connector of its underpart.Detective pole inside carrying step can mate dissimilar test cartridge 2 simultaneously, meets dissimilar underwater horizontal type X-tree.
Test cartridge 2 and test blocking 4, be provided with multiple matching size according to dissimilar underwater horizontal type X-tree, carries out correspondence replacing, realize one multiplex.
Sealing I 8 with sealing II 9 is metal sealing, nonmetal sealing or combination sealing respectively or all.
Principle of work of the present utility model is:
When needs use underwater horizontal type X-tree to carry out pressure test with detective pole to underwater horizontal type X-tree, underwater horizontal type X-tree locks in the locking profile of detective pole upper end (as H4 profile) by the hydraulic connector of its underpart.Then, from top to detective pole body 1, test cartridge 2, test blocking 4, fill tested media in sealing I 8 and the test cavities that form of sealing II 9.According to test related request, the underwater horizontal type X-tree consisted of hydraulic line 7, needle-valve 10 and dividing plate joint 11 detective pole pressure test injects/and discharge system suppresses in test cavity from bottom, carries out pressure test to underwater horizontal type X-tree.After the pressure test of underwater horizontal type X-tree reaches testing requirements, inject/discharge system decompression by the detective pole pressure test of underwater horizontal type X-tree, the tested media in dry test chamber, take out underwater horizontal type X-tree.
Device of the present utility model, by means of only test cartridge 2 and the test blocking 4 of changing detective pole inside, just can realize carrying out pressure test to the underwater horizontal type X-tree of different size, one that achieves underwater horizontal type X-tree detective pole multiplex, improve its versatility, service efficiency is high, and structure is simple, easy to operate, the requirement of underwater horizontal type X-tree pressure test can be met completely.
