Abstract
A deep water well drilling marine riser vertical device comprises a console, a pulley, a fixing hoop, a suspended rope fixing hoop, a suspended rope pulley, a support arm, a buoy, a suspended rope, a pull rope, a guide arm and a guide sail. The console is arranged at the top end of a marine riser; the pulley is arranged on the marine riser by the fixing hoop; the suspended rope fixing hoop is arranged at the bottom end of the marine riser; one end of the support arm is connected with the console; the other end of the support arm is provided with the suspended rope pulley; one end of the suspended rope is fixed on the suspended rope fixing hoop; the other end of the suspended rope is connected with the console by the suspended rope pulley; one end of the pull rope is connected with the suspended rope while other end is connected with the console by the pulley; the buoy is arranged at one side, close to the suspended rope pulley, of the support arm; one end of the guide arm is connected with the console while the other end is fixedly connected with the guide sail; the guide arm and the support arm are positioned on one beeline and are respectively positioned at two sides of the console. The marine riser can be positioned at the vertical state under the action of ocean current by adjusting the pull force of the suspended rope and the pull rope, and the abrasion and friction between a drilling column and the marine riser are reduced.
Description
Technical field
The invention belongs to mechanical field, particularly a kind of marine riser vertical means of using 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 crooked marine riser, produce friction and wear with marine riser, have lost energy, have reduced the life-span of marine riser and drill string etc.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 simple in structure, can make the Deep Water Drilling Riser vertical means of marine riser in plumbness.
Have under the condition of action of ocean current, realize drilling water-separation pipe 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 adapt to current direction.
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 comprised 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 the pulley of its other end through being fixed on marine riser is connected with console; 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; On the above-mentioned support arm near outstanding rope pulley one side, be provided with buoyancy aid.Described guiding device is comprised 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 guiding sail in the downstream of ocean current; Through the effect of leading arm and support arm, will hang rope pulley and be placed in ocean current updrift side, console can hang the pulling force of rope, stay cord by adjusting, make marine riser under the effect of ocean current also in plumbness; Acting as of buoyancy aid is positioned on sea level support arm and outstanding rope pulley, and the effect because of outstanding rope is not bent downwardly.
The present invention compared with prior art tool has the following advantages: console can hang the pulling force of rope, stay cord by adjusting, make marine riser under the effect of ocean current also in plumbness; Can reduce the friction and wear between drill string and marine riser.
