Abstract
The invention relates to a quick connection mechanism for a high-strength dual-seal deep sea anti-ice marine riser, which comprises a female joint, snap springs, seal rings, a male joint, a positioning pin, a detachable bolt and the like. The quick connection mechanism is characterized in that: two or more than two snap springs are arranged between the male joint and the female joint; snap spring grooves are formed at positions, which correspond to the male joint and the female joint, of the snap springs respectively; and a plurality of seal gaskets are formed between the male joint and the female joint. The upper end face of the male joint is fit with the downward end face of the upper part of an inner cavity of the female joint to form a radial fitting seal surface; the lower end faces of the snap springs and the lower bottom surfaces of the snap spring grooves on the correspond positions of the male joint and the female joint form radial fitting surfaces; and slant guiding surfaces which are fit are arranged on the outer side of the male joint and the inner side of the female joint, and axial fitting surfaces which are fit are arranged on the outer side of the male joint and the inner side of the female joint. The quick connection mechanism has the advantages of stable connection structure, large and multiple spans of the fitting surfaces, high rigidity, good seal effect and the like.
Description
Technical field
The present invention relates to the quick cementing unit that is connected of the anti-ice of well head marine riser in the oil exploration of deep-sea zone and the oil exploitation, belong to marine oil field exploitation special equipment.
Background technology
Used marine riser mostly is the segment type marine riser that has snap joint in the deep-sea oil exploitation at present, but the depth of water changes greatly because the deep-sea exists, wave changes greatly, geological conditions is complicated, the not equal problem of the casing programme of every mouthful of well, can not satisfy the environmental requirement in marine site, deep-sea, marine riser having occurred rocks under the effect of wave with rigidity and reduces, sealing performance envelope situation incessantly under the deep-water pressure effect, occurs, had a strong impact on the safety and the production of offshore field.
Summary of the invention
For solve marine oil field anti-ice marine riser in drilling and exploration process exist rigidity low, rock problem order big, the sealing difference, the present invention proposes a kind of high strength double containment deep-sea anti-ice marine riser quick-connect machanism.
To achieve these goals, the present invention takes following technical scheme to implement: it is made up of female joint, jump ring, sealing ring, male joint, alignment pin, demounting bolt etc.It is characterized in that being provided with between male joint and the female joint two or more jump rings; Be respectively equipped with the jump ring groove on the position of male joint and the corresponding jump ring of female joint; Be provided with a plurality of seal washers between male joint and the female joint.Form the radial fit sealing surface after the downward end face in the upper surface of male joint and female joint inner chamber top is fitted, the jump ring groove bottom surface on jump ring lower surface and male joint and the female joint correspondence position forms the radial fit face; The male joint outside is provided with the oblique spigot surface that cooperates with the female joint inboard, and the male joint outside is provided with the axial fitting face that cooperates with the female joint inboard.
The present invention have that syndeton is stable, the fitting face span is big and many, rigidity by force, advantages such as good sealing effect.
Description of drawings
Accompanying drawing 1 assembles schematic diagram for the present invention;
Accompanying drawing 2 is a female joint structural representation in the accompanying drawing 1;
Accompanying drawing 3 is a male joint structural representation in the accompanying drawing 1.
In the accompanying drawings: 1 female joint, 2,6 jump rings, 3,4 sealing rings, 5 male joints, 7 alignment pins, 8 demounting bolts, the axial fitting face of 9 female joints, the axial fitting face of 9 ' male joint, 10 ' jump ring bound plane, 11 female joint spigot surfaces, 11 ' male joint spigot surface, 12 female joint end face seal faces, 12 ' male joint end face seal face.
The specific embodiment
As shown in drawings, process female joint 1, jump ring 2,6, sealing ring 1,2,3,4, male joint 5, alignment pin 7 through special process.And with the upper end welding of male joint 5 with marine riser, female joint 1 is welded with the lower end of marine riser; Alignment pin 7 is assemblied in the relevant position of male joint 5.During offshore construction jump ring 2,6 O-ring seals 3,4 are packed in the relevant position of male joint 5.Utilize the spigot surface 11 of male joint 5 and female joint 1,11 ' and alignment pin 7 carry out the location butt joint of two sections anti-ice marine risers, utilize three sections radial fit faces 9 in female joint 1 and the male joint 5,9 ' realize that the high strength of male joint 5 and female joint 1 is connected, adopt male joint 5 and jump ring 2,6 jump ring confined planes 10 ' be implemented on the whole tubing string and carry, transfer with assembling process in spacing, utilize female joint end face seal face 12 in male joint 5 and the female joint 1 and male joint end face seal face 12 ' carry out secondary seal, adopt O-ring seal 3,4 and male joint 5 and female joint 1 between soft seal carry out three times the sealing.When needing to dismantle being connected of male joint 5 and female joint 1 in the offshore construction, only need demounting bolt is screwed into extruding jump ring 2,6 in the bolt hole of female joint 1, just can be with the releasing that is connected of male joint 5 and female joint 1.
