Description
Technical field
The present invention relates to a kind of burnisher, and in particular to a kind of burnisher for deep-sea marine riser, belong to offshore oil
Gas well downhole tool field.
Background technology
Marine riser is the tubing string to ocean shallow-layer under marine drilling platform, is to completely cut off seawater, circulation in drillng operation
The escape way of mud;By Crude Oil Transportation to submarine pipeline in oil producing operation.But it is easy to stick after pipe inner wall in drillng operation
The debris such as attached mud, landwaste;Easy wax deposition, low temperature easily form solid hydrate and block marine riser in oil recovery process.Drilling well
The debris such as mud, the landwaste of journey residual are cleaned not in time can make the increase of marine riser frictional resistance, and this subsequently creeps under drill string influence
Enter, while marine riser is insufficient to that if cleaning the quality of crude oil will be influenceed during Crude Oil Transportation, therefore be guarantee water proof
The normal use of pipe need to be cleaned to marine riser.Conventional marine riser burnisher is to marine riser sleeve using scraper at present
Inwall carries out scraping cleaning, and this scraping cleaning mode easily causes the damage of water proof inside pipe wall, aggravates the wear-out failure of marine riser,
The marine riser of abrasion is susceptible to burst and squeeze ruin failure under the effect such as drilling fluid, seawater, so be badly in need of one kind can be effective
Cleaning deep-sea marine riser, and the deep-sea marine riser burnisher not damaged to deep-sea water proof inside pipe wall.

Specific embodiment
The burnisher for being used for deep-sea marine riser includes center tube body 1, inner sleeve 2 and outer sleeve 3.Center tube body
The shaft shoulder 4 is provided with 1;Inner sleeve 2 is provided with by symmetrically arranged bearing 5 on the center tube body 1 of the both sides of the shaft shoulder 4.Inner sleeve
4 inner sleeve rib blocks 6 are evenly equipped with 2 appearance circumference of cylinder, the inner sleeve 2 between inner sleeve rib block 6 is provided circumferentially about inner sleeve
Groove 7;One end termination of inner sleeve groove 7 is closure shape.
Upper end cover 10, the other end of inner sleeve 2 are provided with by Upper gasket 8 and clamping bolt 9 on the end face of the one end of inner sleeve 2
End face on bottom end cover 12 is provided with by lower gasket 11 and clamping bolt 9.The purpose of upper end cover 10 and bottom end cover 12 is to right
5 fixations of bearing.Upper end cover 10 is with diameter greater than the diameter of inner sleeve 2, diameter and the equal diameters of inner sleeve 2 of bottom end cover 12;
Sealing ring 13 is provided between upper end cover 10 and bottom end cover 12 and center tube body 1.
The circumference side of inner sleeve 2 is equipped with outer sleeve 3, and outer sleeve 3 is made up of baffle ring 14 and outer sleeve body 15, outer sleeve
The one end of body 15 is fixed with baffle ring 14;Multiple outer sleeve rib blocks 16 are evenly equipped with the circumference of outer sleeve body 15.The gear of outer sleeve 3
The circumferentially spaced about shape of the endoporus of ring 14 is provided with outer sleeve block 17 corresponding with the inner sleeve groove 7 of inner sleeve 2, outer sleeve block
The circumferentially spaced about shape of endoporus of baffle ring 14 between 17 is provided with the corresponding outer sleeve inside groove 18 of inner sleeve rib block 6 with inner sleeve 2,
Pass through between inner sleeve groove 7 and outer sleeve block 17 and in inner sleeve rib block 6 and outer sleeve between outer sleeve 3 and inner sleeve 2
Cooperation between groove 18 is connected with each other;The assembling between outer sleeve 3 and inner sleeve 2 is achieved in, and by outer sleeve block
17 with closure shape the termination of inner sleeve groove 7 cooperation, prevent from mutually being slipped between outer sleeve 3 and inner sleeve 2.
Segmentation ring 19, the inner sleeve 2 of segmentation ring 19 both sides are installed on the inner sleeve 2 between outer sleeve 3 and upper end cover 10
It is upper that wiper ring A21 and wiper ring B22 are provided with by symmetrically arranged back-up ring 20 respectively.
This be used for deep-sea marine riser burnisher segmentation ring 19, back-up ring 20, wiper ring A21 and wiper ring B22 it is interior
Assembling projection corresponding with the inner sleeve groove 7 of inner sleeve 2, the segmentation ring between assembling projection are respectively arranged with the circumference of hole
19th, the inner sleeve rib block 6 pairs with inner sleeve 2 is respectively arranged with the endoporus circumference of back-up ring 20, wiper ring A21 and wiper ring B22
The assembling groove answered;Segmentation ring 19, back-up ring 20, wiper ring A21 and wiper ring B22 are respectively by assembling projection and inner sleeve groove
Cooperation between 7 and between assembling groove and inner sleeve rib block 6 is mutually located(Do not show in figure), it is achieved in segmentation ring 19, gear
The circle 20, assembling of wiper ring A21 and wiper ring B22 on inner sleeve 2.Between being in respectively on wiper ring A21 and wiper ring B22 circumference
Shape is provided with cleaning brush 23;Cleaning brush 23 is made up of brush teeth bunch block.
When the burnisher for being used for deep-sea marine riser works, outer sleeve 3 and inner sleeve 2 are transported with center tube body about 1
It is dynamic, in this course, due to passing through between inner sleeve groove 7 and outer sleeve block 17 and interior between outer sleeve 3 and inner sleeve 2
Cooperation between sleeve rib block 6 and outer sleeve inside groove 18 is mutually slidably connected;Outer sleeve 3 therefore can be on inner sleeve groove 7 be interior
Lower slider;And then wiper ring A21 and wiper ring B22 is also slided up and down in inner sleeve groove 7, it is achieved in marine riser
Cleaning purpose.If card group phenomenon once occur in wiper ring A21 and wiper ring B22, because inner sleeve 2 passes through symmetrically arranged axle
5 are held to be arranged on center tube body 1, therefore inner sleeve 2 can do corresponding rotation, and then drive segmentation ring 19, back-up ring 20, cleaning
Ring A21 and wiper ring B22 is rotated, so as to avoid card group point.
This is used in the burnisher course of work of deep-sea marine riser, and outer sleeve rib block 16 can also be played necessarily to marine riser
Catharsis, and because the external diameter of outer sleeve rib block 16 is slightly less than water proof bore, so outer sleeve rib block 16 can be prevented effectively from
Damage to water proof inside pipe wall;Back-up ring 20 can play a protection to the cleaning brush 23 on wiper ring A21 and wiper ring B22 respectively
Effect, and cooperate with cleaning brush 23 to clean water proof inside pipe wall, so as to carry out comprehensive cleaning to water proof inside pipe wall, and keep away
The damage to water proof inside pipe wall is exempted from.
The burnisher for being used for deep-sea marine riser has simple structure, is easy to dismounting with the spy for safeguarding, security performance is high
Point, when solving traditional marine riser burnisher and working, be all water proof inside pipe wall debris are cleaned using scraper so as to clean every
Pipe inner wall, easily causes to damage to water proof inside pipe wall, is not suitable for the problem of marine riser cleaning.Have cleaning efficiency high simultaneously,
Tool reliability is high, the characteristics of the strong adaptability of underground, with good economic benefit and dissemination;Be particularly well-suited to deep-sea every
Water pipe cleaning is used.
Embodiment described above is only the description carried out to the preferred embodiment of the present invention, not to structure of the present invention
Think and scope is defined, on the premise of design philosophy of the present invention is not departed from, engineers and technicians are to the present invention in this area
