Description
Technical field
The utility model belongs to drilling on waterways technical field, and in particular to a kind of offshore drilling casing wave compensating device.
Background technique
Currently, the construction project of ocean and over-water construction is more, brill especially waterborne is surveyed more and more, and difficulty of construction is increasingly
Greatly, construction environment is severe, and the exploration of especially offshore wind farm project is all the sea area big in stormy waves, and wave is larger when construction, sea
Upper probing usually puts drilling machine and equipment aboard ship, and tripping in sleeve injects seabed soil following certain depth, casing from ship
It is to be connected by the high-strength seamless steel pipe of 3-6 meters of same specifications by connector, drilling rod and drilling tool are the tripping in seas out of casing
Bottom is drilled, and casing is isolated by seawater with mud in casing, and mud returns to mud pit on ship, and shipboard operation is exposed on casing top
0.2-1.5 meters of flat surface, when wave is big, ship floats up and down and rocks very greatly, very inconvenient, low efficiency of constructing, safety
Hidden danger is big.
Utility model content
The purpose of this utility model is to provide a kind of offshore drilling casing wave compensating devices, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions: a kind of offshore drilling casing compensation of undulation dress
It sets, including hull, the side of the hull is equipped with outer tube, and the inside of the outer tube is socketed with casing, and the lower end of described sleeve pipe is logical
Casing joint connection down tube is crossed, the lower end of the down tube extends in ocean bottom soil, and the inner wall lower end of the outer tube is equipped with sealing
Circle and guidance tape.
Preferably, there are two the sealing ring is set, and guidance tape is arranged between two sealing rings.
Preferably, the upper end outer wall of described sleeve pipe also is provided with sealing ring and guidance tape, outer tube and casing by sealing ring and
Guidance tape sealing is slidably connected.
The technical effect and advantage of the utility model: the offshore drilling casing wave compensating device, sealing ring and guidance tape
Sealing structure, can not only seal but also can be slided on sleeve outer wall, and can better conform to execution conditions, and guarantee construction efficiency；
Mechanized construction can be carried out in the presence of a harsh environment, improved working security, reduced labor intensity；Guarantee to apply in the presence of a harsh environment
Working medium amount.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the portion the A enlarged structure schematic diagram of the utility model.
In figure: 1 hull, 2 casings, 3 outer tubes, 4 sealing rings, 5 guidance tapes, 6 casing joints, 7 down tubes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of offshore drilling casing wave compensating device as shown in Figs. 1-2, including hull 1,
The side of the hull 1 is equipped with outer tube 3, and the inside of the outer tube 3 is socketed with casing 2, and the lower end of described sleeve pipe 2 is connect by casing
First 6 connection down tube 7, the lower end of the down tube 7 extend in ocean bottom soil, and the inner wall lower end of the outer tube 3 is equipped with 4 He of sealing ring
Guidance tape 5.
Specifically, there are two the sealing ring 4 sets, and guidance tape 5 is arranged between two sealing rings 4.
Specifically, the upper end outer wall of described sleeve pipe 2 also is provided with sealing ring 4 and guidance tape 5, outer tube 3 and casing 2 pass through sealing
Circle 4 and the sealing of guidance tape 5 are slidably connected.
Increasing by an outer tube 3 in the periphery on casing top, 1 upper flat plate of hull is exposed on the top of outer tube 3 can be relatively fixed,
General 0.2 meter or so, seawater and mud are isolated by the sealing structure of sealing ring 4 and guidance tape 5 for the lower part of outer tube 3, this is close
Sealing mechanism can not only have been sealed but also can have been slided on 2 outer wall of casing, and marine wave drives hull 1 to float up and down, and nor affect on brill
Visit work.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
