Basal disc is substantially easy welding structure frame, is had the following disadvantages：1st, typically directly sat using tree bottom and be put into test basal disc
On, production tree fixes insecure, and test has certain risk.2nd, can exist as subsea production tree is installed well head is first certain
The bias of angle, conventionally test basal disc does not possess the ability of regulation angle, it is impossible to simulate the well head head of different angles with recovering the oil
Set the process of docking.
The content of the invention
In view of the above-mentioned problems, basal disc is tested it is an object of the invention to provide a kind of subsea production tree of adjustable-angle, its
It is connected firmly, setting angle is adjustable.
To achieve the above object, the present invention takes following technical scheme：A kind of subsea production tree test of adjustable-angle
Basal disc, it is characterised in that：It includes lower bottom base, hydraulic jack, globular hinge block, upper bed-plate, jointing supporting plate and under water
Production tree jointing；The lower bottom base top is provided with the hydraulic jack, and the hydraulic jack is distributed on the lower bottom base
At four drift angles；The piston rod end of the hydraulic jack is provided with the globular hinge block, and the globular hinge block is fixed on
The upper bed-plate bottom；The jointing supporting plate, the oil recovery are provided with the upper bed-plate upper middle position
Tree jointing is fixedly installed in the jointing supporting plate.
Further, the globular hinge block includes pedestal and two halves spherical structure, and described pedestal one end is fixed on the upper bottom
On seat, the pedestal other end is provided with ball recess；The two halves spherical structure connects and composes spheroid, the spheroid side and institute
State ball recess to be hinged, the spheroid opposite side is fixed on the piston rod end of the hydraulic jack.
Further, connected between the globular hinge block and the upper bed-plate using bolt or Type of Welding.
Further, the upper bed-plate cross section is I-shaped steel welding construction, and edge uses round steel pipe reinforcement of weld.
Further, the jointing supporting plate is thickening steel plate.
Further, the subsea production tree jointing uses the underwater wellhead analogue means with H4 sections.
The present invention is due to taking above technical scheme, and it has advantages below：1st, the present invention provides for subsea production tree
One general installation foundation (simulation well head head) relatively, subsea production tree connection is more reliable, and test process is more stable.2nd, this hair
Bright to be set using upper and lower base, upper bed-plate is movable, and lower bottom base is fixed, using the teaching of the invention it is possible to provide certain angle of inclination, is come under simulation water
Well head head eccentric state, and then installability of the subsea production tree under water under mouth eccentric state can be tested by land.It is comprehensive
Upper described, the present invention can be applied in hydrocarbon production system under water extensively.
