Description
Technical field
The present invention relates to deep water hydrocarbon drilling applications, especially a kind of high undersea hydrostatic pressures are sealed with magnetostrictive displacement sensor
Device.
Background technique
The newly-increased oil and gas discovery amount in the whole world mostlys come from sea, especially deep water and ultra-deep-water in recent years.From deep water
Although discovery number it is few, discovery amount is very huge, while showing the trend that the depth of water is deeper, discovery amount is bigger.Deep water
It is drilled the important component that well operations are exploratory engineering of off-shore petroleum/gas reservoir exploitations, is directly related to the success or failure of deepwater petroleum exploration exploitation.
It needs to use various underwater kits and operational instrument during deepwater drilling and completion, due to wave stream and other works
The influence of industry factor, these equipment can generate corresponding movement under water, how guarantee the safe and reliable fortune of these underwater equipments
Row has become the overriding concern factor of deepwater drilling and completion.By taking Deep Water Drilling Riser as an example, carried in environmental load and operation
The complicated mechanical behavior such as bending deformation, vibration can be generated under the influence of lotus, needed thus comprehensive using theory analysis, numerical simulation
And the means such as physical analogy study the mechanical behavior of marine riser.When carrying out simulation experiment study to marine riser, need
Various load are loaded to it, various parameters of the accurate measurement including displacement, strain.Since marine riser works in high-pressure water-ring
Under border, therefore where having become the heavy difficult point of simulated experiment to the measurement of marine riser displacement under high pressure water environment.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of high undersea hydrostatic pressures magnetostrictive displacement sensor sealing device.This is close
Seal apparatus is mainly by movement parts, magnetostrictive displacement sensor, axial sleeve, central seal ring, sealing flange, end under high pressure water
Portion's clip, data collecting instrument, hydraulic fitting and sebific duct, screw and sealing ring composition.
Central seal ring, sealing flange, hydraulic fitting and end clip are sequentially arranged on sensor in the present invention, in
There is sealing ring between heart sealing ring and sensor and sealing flange.
Sensor is fixed together by screw and central seal ring in the present invention.
P-wire in the present invention on sensor is connected after being pierced by hydraulic fitting and sebific duct with data collecting instrument on ground.
Mesohigh sub-aqua sport part of the present invention is sequentially connected the magnet ring on axial sleeve and sensor, and whole device passes through end
Hole on portion's clip is fixed.
In the present invention when movement parts move under high pressure water, magnet ring and magnetic bar can be made to generate relative displacement, this relative displacement
It can be captured by data collecting instrument.
