21 century be since the dawn of human civilization countries in the world to the fiercest age of the competition of marine resources.Ocean is the abundantest treasure-house of many resources, is therefore becoming the main battle ground of fighting for resource between various countries.
Offshore oil proved reserves account for the 50%-70% of Global Oil reserves at present, and offshore oil output accounts for 34% of Global Oil total output, and the marine petroleum exploitation output value accounts for 60% of total Output Value for Oceanic Economy.To global ocean oil-gas exploration and development investment in 2015, will reach every year approximately 3,600 hundred million dollars.The larger hydrocarbon Tanaka who find to surpass 100,000,000 tons of reserves for nearly 10 years, marine oil and gas accounts for more than 60%, wherein half in the depth of water more than 500 meters deep-seas.
The above dependence on import of China's deep-sea equipment critical material 90%; in the current offshore and gas development equipment of building in China; the average less than 10% of the localization rate of parts and components of its corollary equipment; critical material dependence on import; therefore; be applicable to the investigation of materials of abyssal environment and the bottleneck that exploitation has become the deep-sea technology development of restriction China, particularly energy drilling field is particularly outstanding.
Deep-sea oil drilling riser buoyance bucking-out system is the important ingredient of deep-sea oil drilling and extracting equipment.In marine petroleum exploitation system, drilling water-separation pipe is the pipeline that connects seabed and offshore boring island, and inner generally have the oil of high pressure or air-flow to pass through, and the effect of wave, current load is born in outside.And riser system is very heavy, if do not take buoyancy compensation during underwater operation, huge to the tractive force of offshore boring island.For weight reduction and the tractive force to platform, the method conventionally adopting is exactly, at marine riser, the weight that solid buoyancy material alleviates marine riser is installed outward.In addition these buoyant materials that, are fixed on marine riser external surface also can play good thermal insulation and protective effect by the drilling device in severe marine environment to long-term work.
Utility model content
The purpose of this utility model is, a kind of deep-sea oil drilling and extracting equipment buoyancy compensation system is provided, to solve the existing many weak points of existing system.This utility model is applicable to deep-sea oil drilling field.
The technical problem of the required solution of the utility model, can be achieved through the following technical solutions:
A kind of deep-sea oil drilling and extracting equipment buoyancy compensation system, it is characterized in that, comprising: solid buoyancy material, keel, tie up retaining mechanism, described keel are along the peripheral distribution of marine riser, between described keel and marine riser, arrange and tie up retaining mechanism, described keel cover solid buoyancy material outward.
Further, described solid buoyancy material is circulus, and the groove that holds keel is set in described solid buoyancy material.
Further, the raised ribs that described keel are a plurality of strips, the length direction of described keel is along the axial direction setting of marine riser, and the width of described keel is along the radial setting of radial direction of marine riser.
Further, described keel merogenesis arranges.
Further, described in tie up retaining mechanism and formed by strapping, locking device, locking device is the periphery that arcuate structure fits in marine riser, and the hole that strapping passes is set between described locking device and keel.
The beneficial effects of the utility model:
Epoxy resin and solidfied material thereof that the utility model adopts are that in thermosetting resin, combination property is best, and its mechanical property is high, adhesive property is excellent, cure shrinkage is little, processing performance is good, is suitable as the matrix resin of solid buoyancy material.
The utility model solid buoyancy material adopts polymer hollow particles/glass microballoon coupling system, has replaced existing traditional glass microballoon system, can, guaranteeing, under the prerequisite of buoyant material intensity, further to reduce density of material, improve material buoyancy compensation function.
