Description
Technical field
The present invention relates to offshore and gas development equipment technology field, particularly a kind of Deep Water Drilling Riser and drilling rod abrasionproof
Anti-attrition protection device.
Background technology
Deepwater drilling and the maximum differential of land drilling well are the presence of a special device between drilling platforms and seabed, i.e.,
Marine riser.Marine riser refers to the key equipment for connecting subsea blow out preventer and sea drilling platforms, be under offshore drilling platform to
One interface channel in seabed, in drillng operation, the major function of marine riser is isolation seawater, and the circulation for forming drilling fluid is led to
Road, sets up the effects such as drilling tool into the passage on stratum, concatenation additional line.It can thus be seen that once marine riser accident is by nothing
Method carries out normal deepwater drilling operation.However, in deepwater drilling, marine riser is in seawater, marine environment load is received
The effect of lotus.Easily occur bending and deformation and produce vortex-induced vibration.Additionally, there is drilling rod inside marine riser, drilling rod is with certain
Rotating speed carries out drillng operation.When marine riser occurs bending and deformation with vortex-induced vibration, water proof inside pipe wall will with tool joint and
Outer wall comes in contact abrasion.If long-time contact wear, water proof thickness of pipe wall is thinning, this will substantially reduce the intensity of marine riser, lead
Cause marine riser that fracture accident occurs.Additionally, external diameter increase and joint outer wall are welded with coarse hardbanding at tool joint,
Exacerbate the abrasion of marine riser and drill string.
Drill string wear problem gradually receives attention, for example, Chinese Patent Application No. in drilling applications：
201310731497.X discloses a kind of method and wear-resistant joint for improving tool joint abrasion resistance in cased well, and its method is
Wearing bush is set up on joint body to improve the intensity of tool joint；Wearing bush is that curing is added in polytetrafluoroethylene (PTFE)
Molybdenum, carbon dust and tin bronze are compressing, are resistant to 250 DEG C of high temperature, and coefficient of friction is less than 0.1；Wearing bush endoporus and joint body
Cylindrical gap coordinates, and the position that wearing bush is installed on joint body is provided with anti-abrasive coatings, and anti-abrasive coatings pass through laser melting and coating technique
It is evenly coated on joint body and the position of wearing bush is installed.For in the process implementing difficulty, the manufacture craft of its wearing bush is answered
It is miscellaneous, high cost；For from abrasionproof effect, wearing bush still belongs to sliding friction with the friction of outside, the abrasionproof effect that it is played
Still it is unable to reach optimum state.And for example, Chinese Patent Application No.：200810044266.0 disclose and one kind for mud be situated between
Matter deep ＆ ultra-deep well, box cupling shell is arranged at centralizer joint body, and outer surface is provided with medium runner and wedge compression groove,
Every being distributed on box cupling shell；Inside is equipped with a pair of rolling bearings, and is directly installed on joint body with interference；Rolling bearing,
Sleeve and self-lubricating sealing ring group are symmetrically installed on the inner surface at box cupling shell two ends respectively；Filled out in the middle part of two roller bearing shops
Fill filling graphite in the top filled cavity between chamber and bearing and joint body.The technical problem that the invention is solved is drilling tool and the borehole wall
Between abrasion, and mainly in land drilling well, but for deepwater drilling field, the marine riser inside its drilling tool
Abrasion between drilling rod still cannot be solved effectively.
Wear problem is contacted with drilling rod for marine riser, is not had device and the method reduction of correlation both at home and abroad or is subtracted
The abrasion of slow marine riser.
The content of the invention
Shortcoming it is an object of the invention to overcome prior art, there is provided a kind of Deep Water Drilling Riser is anti-with drilling rod to be worn away
Mill protection device, simple structure of the present invention, modern design be suitable for varying environment, can effectively reduce in deepwater drilling operation every
Water pipe may come in contact and rub with drilling rod in all passages for passing through, or as respective in marine riser or drilling rod separate operaton
Enhancing and protection device.
