Development along with Magnetic resonance imaging (MRI) technology; MRI begins to be used to the research of porous medium, well logging etc.; Nuclear magnetic resonance log does not receive the influence of reservoir rock all the components, and it can provide information such as amount of fluid in the blowhole, fluid behaviour and fluid pore-size.Along with the use of the nuclear magnetic resonance apparatus that uses superconducting magnet and pulse radiation frequency, characteristics such as can obtaining more accurate hole information, help to analyze fluid content in the porous medium of pore size more, be mobile.Because the shielding action of metal pair Magnetic resonance imaging signal, the Magnetic resonance imaging sample hose can not be used metal material processing fully, and therefore the high pressure basket of traditional stainless steel material can not be applicable to MRI equipment.Because probe size is less, make the size of basket also receive very big restriction simultaneously.And carry out the MRI experiment, and not only want satisfied temperature, pressure controlled requirement, also for convenience detach, cleaning simultaneously in the process, therefore seeking suitable basket becomes the research focus.
The utility model content
The purpose of the utility model provides a kind of basket that is used for NMR imaging instrument.
The basket that is used for NMR imaging instrument that the utility model provides, it comprises the inner layer sleeve and the outer layer sleeve that is set in the nonmetallic materials on the said inner layer sleeve of nonmetallic materials, forms ring cavity between said inner layer sleeve and the said outer layer sleeve; Said inner layer sleeve two ends are respectively equipped with the plug of the said inner layer sleeve of sealing.
In order to support outer layer sleeve, can be respectively equipped with the pressure cap of the said outer layer sleeve of sealing at the two ends of said outer layer sleeve, simultaneously, each said pressure cap all is connected with said inner layer sleeve; Be tightly connected between each said pressure cap and the said outer layer sleeve.
For better seal pressure cap and outer layer sleeve, between each said pressure cap and said outer layer sleeve, be equipped with O-ring seal A.
In order to realize, on each said pressure cap, be equipped with the fluid passage that communicates with said ring cavity to the basket temperature controlling.
In order to be communicated with extraneous isothermal liquid, be equipped with the connector of turnover for liquid at the port of each said fluid passage.
In order better to seal inner layer sleeve, each said plug all is threaded with said inner layer sleeve, and between each said plug and said inner layer sleeve, is equipped with O-ring seal B.
To form high pressure chest in the inner layer sleeve in order making, to be equipped with passage (can be used for vacuumizing, air inlet and water inlet) on each said plug; Said passage is connected with the chamber of said inner layer sleeve.
In order to prevent that organdy outwards moves in the inner layer sleeve, between the chamber of each said plug and said inner layer sleeve, can also be provided with pressure pad and screen pack, said pressure pad is near plug, and said screen pack is near the chamber of inner layer sleeve.
Above-mentioned inner layer sleeve is used for back-up sand, and the liquid coolant that can flow in the outer layer sleeve generates the temperature of decomposing with the control hydrate, therefore, and the more said outer layer sleeve wall thickness of said inner layer sleeve wall.
Because the shielding action of metal pair Magnetic resonance imaging signal, the Magnetic resonance imaging sample hose can not be used metal material processing fully, and outer layer sleeve and the inner layer sleeve therefore selected for use are all processed with nonmetallic materials, and said nonmetallic materials are polyimide.
Each said plug is processed with alloy, has formed the part metals material with nonmetallic materials outer layer sleeve and nonmetallic materials inner layer sleeve like this and has added the basket that the top nonmetallic materials are processed, and it is withstand voltage can to satisfy high requirement (12MPa).
The basket of the utility model can be widely used in the nuclear magnetic resonance log, has the following advantages:
1. basket adopts nonmetallic materials, has guaranteed the Magnetic resonance imaging quality, and can reach pressure requirement (12MPa);
2. basket can be simulated the Whole Process Control that hydrate generates, decomposition is tested in the accumulation horizon sample of large-size; And in experimentation, generation, decomposition and the air water flow characteristics of hydrate in sedimentary deposit carried out the measurement of imaging observation and some parameter through NMR imaging instrument, experimentize like the accumulation horizon that can simulate diameter 15mm length 200mm.
3. basket is taked double-layer sleeve structure, can realize the accurate control of temperature, pressure.
