The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
As shown in Figure 1; Offshore Drilling Riser clamping system structure of the present invention is; Be respectively arranged with a plurality of stretcher assemblies 1 around being included in floating drilling platform 13; The accumulator 16 of each stretcher assembly 1 all is communicated with high pressure air system 5 through high pressure line 4, and high pressure line 4 is provided with control operation platform 6, and high pressure air system 5 also is communicated with subsequent use high pressure air system 8;
With reference to Fig. 2, Fig. 3; Stretcher assembly 1 structure comprises tensioning fluid cylinder 17; The tensioning fluid cylinder is respectively arranged with top sheave group 14 and downslide wheels 15 in two ends about in the of 17; Downslide wheels 15 are fixed on the fixed end of tensioning fluid cylinder 17, and top sheave group 14 is fixed with the piston termination of tensioning fluid cylinder 17, and the distance between top sheave group 14 and the downslide wheels 15 changes with the flexible of piston; Accumulator 16 cavity of resorptions are full of highly pressurised liquid, and accumulator 16 epicoeles are full of gases at high pressure, and accumulator 16 cavity of resorptions are communicated with tensioning fluid cylinder 17 plunger shaft, and accumulator 16 epicoeles are communicated with high pressure air system 5;
Stretcher assembly 1 both can be installed in around the floating drilling platform (ship) 13, also can be installed in other appropriate locations of floating drilling platform (ship) both sides.The quantity of stretcher assembly 1 is according to circumstances selected 6 groups, eight groups, 10 groups, 12 groups or other quantity for use.Stretcher assembly 1 adopts biliquid cylinder form, and promptly two marine riser tensioner apparatus integrate, and also can adopt single fluid cylinder form.Tensioning fluid cylinder 17 in the stretcher assembly 1 integrates with accumulator 16, also can be installed separately accumulator 16 in the nearer position of tensioning fluid cylinder 17.
Offshore Drilling Riser system embodiment of the present invention comprises eight groups of stretcher assemblies 1, and eight groups of high pressure air systems 5 are installed respectively near each stretcher assembly 1, and links to each other with accumulator on the stretcher assembly 1 through high pressure line respectively; Be arranged in floating drilling platform (ship) 13 both sides, on the wire rope 2 one end fixed tensioning device assemblies 1, and through slide down wheels (14,15) derivation, after leading block 3 guiding, evenly distributing is suspended on the tightening hoop 10 of riser system 11 again; In addition,, be furnished with subsequent use high pressure air system 8, link to each other with eight groups of high pressure air systems 5 respectively in order to improve reliability; Control operation platform 6 is installed on the rig floor plane, and realization is controlled clamping system, and stretcher assembly 1 is realized control automatically during the native system operate as normal, and control operation platform 6 is merely auxiliary operation in particular cases.
The operating principle of apparatus of the present invention is,
When not working, the piston rod of tensioning fluid cylinder 17 is mediated, guarantees that the stroke up and down of fluid cylinder is equal basically, guarantee simultaneously accumulator 16 about two chamber volumes equal.
When in running order, because the 17 internal pressure effects of tensioning fluid cylinder make piston rod remain a constant thrust, thrust passes to tightening hoop 10 through wire rope 2, for riser system 11 provides a constant top tension force; When floating drilling platform 13 receives the effect of wave and when rising, because the invariant position of tightening hoop 10, and stretcher assembly 1 rises with floating drilling platform 13; Thereby what cause wire rope stressedly has the trend that becomes big; Wire rope 2 compressing tensioning fluid cylinders 17 piston rods, so piston rod moves downward, the liquid of tensioning fluid cylinder 17 gets in the accumulator 16; The gases at high pressure compression; Top sheave group 14 and 15 hypotelorisms of downslide wheels on the stretcher assembly 1 discharge wire rope 2 and satisfy the needs that platform rises, and guarantee that basically wire rope receives constant pulling force simultaneously; In like manner; When floating drilling platform 13 receives the effect of wave and when sinking, wire rope 2 tension force diminish, the gases in the accumulator 16 expand; Promoting highly pressurised liquid gets in the tensioning fluid cylinder 17; Top sheave group 14 on the stretcher assembly 1 and the growth of downslide wheels 15 spacings reclaim wire rope 2 and satisfy the needs that platform sinks, and basic simultaneously assurance wire rope 2 receives constant pulling force.
Be provided with real-time monitoring system in the control of the present invention system; Effectively prevent accidents such as wire rope breaks off suddenly, riser system is promptly separated, riser system disconnection suddenly; Guarantee the safe and reliable operation of marine riser clamping system; System architecture is simple, easy to operate, easy care; Can effectively be that the Offshore Drilling Riser system provides substantially invariable top tension force in the floating drilling platform, and compensation floating drilling platform heave movement up and down, for ocean floating type drilling platform carries out drillng operation maximum safety guarantee is provided.
