Abstract
A kind of Deep Water Drilling Riser vertical means, comprises console, pulley and clips, outstanding rope clips, outstanding rope pulley, support arm, buoyancy aid, outstanding rope, stay cord, leading arm and guiding sail.Console is arranged on the top of marine riser; Pulley is arranged on marine riser by clips; Outstanding rope clips is arranged on marine riser bottom; One end of support arm is connected with console, and its other end is provided with outstanding rope pulley; One end of outstanding rope is fixed on outstanding rope clips, and the other end is connected with console through outstanding rope pulley; One end of stay cord is connected with outstanding rope, and the other end is connected with console through pulley; Support arm near outstanding rope pulley side is provided with buoyancy aid; One end of leading arm is connected with console, and its other end is connected with guiding sail; Leading arm and support arm, lay respectively at the both sides of console point-blank.The present invention by regulating the pulling force of outstanding rope, stay cord, can make marine riser also be in plumbness under the effect of ocean current, reducing the friction and wear between drill string and marine riser.
Description
Technical field
The invention belongs to mechanical field, particularly a kind of marine riser vertical means for deep sea drilling.
Background technology
In deep-sea oil, natural gas and geological drilling process, with marine riser insulating sea water, set up circulation of drilling fluid passage and protect the marine environment.After action of ocean current is on marine riser, marine riser generation transverse bending.In drillng operation, drill string etc. move in bending marine riser, produce friction and wear, have lost energy, reduce the life-span of marine riser and drill string etc. with marine riser.For this reason, reduce device and the technology of drill string etc. and the friction and wear of marine riser, significant to deep sea drilling.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, marine riser can be made to be in the Deep Water Drilling Riser vertical means of plumbness.
Under the condition with action of ocean current, realize drilling water-separation pipe and be in plumbness, Deep Water Drilling Riser vertical means must possess two functions: (1), under the effect of ocean current, marine riser is in plumbness; (2) automatically current direction is adapted to.
In order to achieve the above object, to solve the technical scheme that this technical problem adopts as follows in the present invention:
The present invention mainly comprises suspension cable marine riser vertical means and guiding device.Described suspension cable marine riser vertical means is made up of console, pulley and clips, outstanding rope clips, outstanding rope pulley, support arm, buoyancy aid, outstanding rope, stay cord; Console is positioned on sea, is fixed on the top of marine riser; Pulley is arranged on the different depth of marine riser on demand by clips; Outstanding rope clips is arranged on the bottom of marine riser; Support arm is positioned on sea level, and its one end is connected with console, and its other end is provided with outstanding rope pulley; One end of outstanding rope is fixed on outstanding rope clips, and the other end of this outstanding rope is connected with console through outstanding rope pulley; One end of the stay cord identical with clips quantity with pulley is connected with outstanding rope, and its other end is connected with console through the pulley be fixed on marine riser; The quantity of stay cord and pulley and clips and installation site, determine according to ocean current, sea water advanced, marine riser structure and material; Above-mentioned on the support arm of outstanding rope pulley side, be provided with buoyancy aid.Described guiding device is made up of leading arm and guiding sail; One end of leading arm is connected with console, and the other end is connected with guiding sail; This leading arm and above-mentioned support arm, lay respectively at the both sides of console point-blank.
On offshore boring island or the ship positionning sea level directly over well head; Ocean current is flushed to the downstream of ocean current guiding sail; Through the effect of leading arm and support arm, outstanding rope pulley is placed in ocean current updrift side, console can, by regulating the pulling force of outstanding rope, stay cord, make marine riser also be in plumbness under the effect of ocean current; Acting as of buoyancy aid makes support arm and outstanding rope pulley be positioned on sea level, is not bent downwardly because of the effect of outstanding rope.
The present invention compared with prior art tool has the following advantages: console can, by regulating the pulling force of outstanding rope, stay cord, make marine riser also be in plumbness under the effect of ocean current; The friction and wear between drill string and marine riser can be reduced.
