Technical field
The utility model belongs to technical field of nonferrous metal processing, relates to Ti metal processing, is specifically related to a kind of deep-sea oil drilling-production equipment high-performance titanium and connects seal ring.
Background technique
From the discovery situation of global large oil and gas fields for over ten years recently, the newly-increased petroleum reserves of 60% ~ 70% is all derived from ocean, and the reserves found in its mesopelagic (200 meter Dao1000 meter Shui Shen) probably account for 45% ~ 50%.Therefore, deep-sea has become the main region of whole world oil gas field reserve replacement.Single with deep-sea, global deep-sea oil gas reserves are more than 2,000 hundred million tons, and its PetroChina Company Limited. accounts for 60% ~ 70%, and rock gas accounts for 10% ~ 20%.Therefore target is invested off-lying sea from coastal waters by the mankind, but deep-sea exploration needs with exploitation technology the limit challenging mankind's science and technology, and various countries start to fight for deep-sea oil gas resource, and sight is also aimed at the exploitation of deepwater field by China.The drilling exploitation of deepwater field needs high-grade, precision and advanced in a large number deepwater work equipment, but the current equipment of China is also lower.At deep-sea drilling exploitation oil gas, though have ten thousand/ accident probability, by the restriction of deep-sea geological condition, be difficult to search out the most effective solution route at short notice with artificial strength.Therefore, the working environment of the probing of deep-sea oil, exploitation or conveying equipment (being called for short " drilling-production equipment ") is harsh, and its long lifetime, high reliability is even more important.
At present, in petroleum drilling and mining industry, deep-sea oil drilling-production equipment mostly adopts the flange plate of steel (comprising stainless steel) to dock and connects with bolt or adopt complicated connection part (being called for short " assembly ") to connect two sections of oil transport pipelines, it is installed or changes intricate operation, and its internal stress of installing rear assembly is uneven.Therefore, when the assembly of steel uses usually in 1000m ~ 3000m deep-sea, due to seawater corrosion resistance ability, there is short shortcoming in working life, the accident that easy induced breakage, damaged leakage of oil or equipment cannot work.If steel connects black box generation, corrosion just must be changed or keep in repair, and drilling-production equipment is in deep-sea often not easy-maintaining or replacing, so along with deep-sea oil drilling is to darker depth development, particularly when being deeper than 3000m deep-sea and using, steel connects black box and has been difficult to the needs meeting deep-sea oil drilling.
Model utility content
Ti metal then because its density is little, intensity is high, specific strength is large and thermal expansion coefficient is little, corrosion-resistant, high temperature and the advantage such as cryogenic property is good.If utilize its advantage, the relatively simple titanium of project organization or titanium alloy are tightly connected ring (being called for short " titanium connection seal ring ") improve its performance index through suitable process treating, carry out alternative steel and connect black box, effectively overcome above-mentioned shortcoming, realize the needs of deep-sea oil drilling-production equipment long lifetime, high pressure resistant, seawater corrosion resistance and easy care.Therefore, the utility model provide a kind of deep-sea oil drilling-production equipment with titanium connect seal ring, it has internal thread can connect two sections of transport pipe, also can use on miscellaneous equipment.It can meet 1000m ~ 3000m deeply or darker deep-sea use, working life and the production efficiency of drilling-production equipment can be improved, corrosion failure leakage of oil also can be avoided the pollution of ocean environment.The concrete technological scheme that the utility model adopts is as follows.
A kind of deep-sea oil drilling-production equipment high-performance titanium connects seal ring, comprise ring body (1), its profile is circular, hole centered by inside, is characterized in that: the outer round surface circumferencial direction along described ring body (1) has circular boss (2), platform (3), angled end-face (4) and planar end surface (6) successively.
Further, the inner circumferential surface (5) of described center hole has internal thread (7).
Further, described ring body (1) outer round surface is divided into two-part by described boss (2); The axial width ratio of described boss (2), platform (3) and angled end-face (4) is 3: 2: 4; Described boss (2) rectangular in cross-section.
Further, the inner circumference radius (R1) of described ring body (1) is 223.5mm; First excircle radius (R2) of described angled end-face (4) is 250mm, the second excircle radius (R3) is 284mm; The excircle radius (R4) of described boss (2) is 300mm; The axial width (L) of described ring body (1) is 150mm, the axial width of described boss (2) (N) is 30mm, the axial width of described platform (3) is 20mm, the axial width of described angled end-face (4) is 40mm.
Further, material is titanium or titanium alloy.
Compared with the prior art, the technique effect of titanium connection seal ring of the present utility model is:
First, the structural design that titanium connects seal ring can ensure installing and using the stress distribution in process evenly, and its structure is relatively simple, installs, changes or safeguard also simple and easy, substitute the connection part of multiple component formation with component, its reliability also can significantly improve simultaneously; Secondly, titanium connects seal ring after Overheating Treatment, and its performance index such as tensile strength, yield strength, all increase substantially than common titanium article.Titanium of the present invention connects seal ring, and through measuring, tensile strength is 565MPa, far above U.S. ASTMB381 standard requires common titanium article tensile strength 62.3%; Yield strength is 460MPa, far above 67.3% of this standard; Specific elongation is 25.2%, far above 26% of this standard; Reduction of cross sectional area is 44%, far above 46.7% of this standard.
