Description
Technical field
The present invention relates to a kind of butt joint locking mechanism, particularly relate to a kind of static seal Wedge-type butt joint locking mechanism of subsea control modules, belong to Offshore Engineering field.
Background technology
In Global Oil total resources, about 34% is Marine oil and gas resource, Global Oil resource total reserves about 1,000 hundred million tons, and at present demonstrated reserves be just about 38,000,000,000 tons, and demonstrated reserves nearly 80% at deep water sea area.In the last few years, along with the continuous increase of global energy requirement and the significantly rise of international oil price, people are impelled constantly to expand global Oil Gas exploratory development (E & P) gross investment scale.According to related data statistics, from calendar year 2001 by 2005, offshore oil and gas E & P investment rises to about 90,000,000,000 dollars from about 69,000,000,000 dollars, increases about 1/3rd; Deep-sea oil gas E & P capital investment shares account for global offshore oil and gas E & P and invest the ratio of total share also in increase, deep-sea oil gas E & P investment rises to about 14,000,000,000 dollars from about 9,200,000,000 dollars, increases about 1/2nd.According to statistics by 2010, global deep-sea oil gas E & P investment reaches about 20,000,000,000 dollars, comparatively within 2005, increases by 43%.As can be seen here, the exploitation of deep water hydrocarbon resource becomes the emphasis of Global Oil resource exploitation gradually.
Subsea control modules (SCM) is the nucleus equipment of Subsea Control Systems, SCM controls each valve on subsea production tree, the state of monitoring christmas tree, and in time to the equipment feedback undersea device information on sea, and the co-ordination of water surface production platform and subsea production system is also realized by subsea control modules.Usual subsea control modules installs basal disc carry out locking with control module waterborne and be directly installed on the equipment that will control, as: subsea production tree, subsea manifold etc.
At present, the version of the existing many employings of catch gear under water dynamic seal, applies in supporting diving and deepwater environment, but due to its complex structure, and a lot of dynamic seal only when mechanism's high-speed operation competence exertion go out its sealing property, so be not suitable for being applied on subsea control modules.Because subsea control modules only seals position and just has relative motion when installing and dismantle, therefore use static seal structure instead, static seal structure not only significantly reduces working accuracy and the assembly precision demand of part, and, when static seal catch gear works, leakproofing material can not be worn, therefore static seal catch gear often has longer service life than movable sealing structure.
At present, existing underwater mating catch gear has number of different types, control locking and conciliate lock control principle majority employing worm drive mechanism, no matter be dynamic seal or static seal, its hermetically-sealed construction is mainly all arranged on lock shaft, the multiple locating dowel pin of the docking many employings of guiding mechanism carries out guide-localization, and guide finger requires that the precision of processing and assembling is very high, often occurs the situation that docking is stuck.And the many employings of catch gear utilize stuck mechanism to lock by rotation lock mandrel and lifting lock shaft, the lock shaft of this structure not only will move up and down, and also needs to carry out spinning movement, high to under-water robot (ROV) operation requirements; And along with the increase of the depth of water, Underwater Pressure strengthens and the reduction of visbility, has higher requirement for the docking of catch gear under water and the convenience of locking and ROV operation.
