Description

Magnetic refrigeration tubular type heat preservation Sampling driller
Technical field
It is more particularly to a kind of to be used for polar region moral purity and land permafrost region the utility model is related to rock core Sampling driller field The magnetic refrigeration tubular type heat preservation Sampling driller of Gas Hydrate Drilling.
Background technology
Solid magnetic substance (system that magnetic ion is formed) when being magnetized by magnetic fields, strengthen by the magnetic order degree of system (magnetic entropy reduction), externally releases heat;Again by its degaussing, then magnetic order degree decline (magnetic entropy increase) absorbs heat from the external world again Amount.This magnetic ion system applies in magnetic field is known as magnetothermal effect with the thermal phenomenon appeared in removing process.If this Exothermic process caused by endothermic process caused by two adiabatic demagnetizations of sample and adiabatic magnetization is connected with a Xun Huan, by outer Add magnetic field, control magnetic lazy consciously, so that it may so that magnetic material constantly from one end absorb heat and in other end heat release, so as to reach To the purpose of refrigeration.
The content of the invention
It is effective saving material, energy saving, sustainable use for gas hydrates and the occurrence condition of moral purity Principle, the utility model be intended to provide it is a kind of simple for process pollution-free, sample take it is efficient, to moral purity and gas hydrates Primordial condition disturb small magnetic refrigeration tubular type heat preservation Sampling driller.
In order to achieve the above objectives, the utility model provides following technical solution:
A kind of magnetic refrigeration tubular type heat preservation Sampling driller for polar region moral purity and land permafrost region Gas Hydrate Drilling, Mainly it is made of both arms drilling rod, rolling bearing, magnetic basket, carbon steel basket, separator.Wherein both arms drilling rod is by inside and outside rock Heart pipe forms, and inner tube is made of common basket and magnetic basket, and outer basket is by common basket and magnetic rock Heart pipe forms;Inside and outside basket is connected by rolling bearing, and rolling bearing is located on bearing spider.Inner tube is kept during normal drilling With drilling rod drill bit is driven to rotate, is designed with slide on the outer wall of inner tube, and on the inner wall of outer tube on be designed with sliding slot, outer tube Outer wall be designed with centralizer, during normal operation, since centralizer is against rock stratum, slide can be resisted from magnetic basket Attraction, so outer tube holding does not rotate;
The annular gap of inner tube is an integral structure with inner tube design, by divider separates into symmetrical two Point, and paramagnetism salt is filled in the semi-ring of annular gap, when being magnetized by magnetic fields, the magnetic order degree of system is strengthened (magnetic entropy reduction), externally releases heat;Again by its degaussing, then magnetic order degree decline (magnetic entropy increase) absorbs heat from the external world again Amount, by the inner and outer pipes for rationally designing basket so that in normal drilling, since drilling rod drives the inner tube of basket to rotate, Magnetic field is caused to change, paramagnetism salt continuously can absorb heat from rock core and be discharged into drilling fluid, realize The low-temperature insulation of gas hydrates rock core and polar region moral purity samples.Broken rock by clamp spring card after rock core is full of basket The heart carries and drills through the heart;
Paramagnetism salt is ferriammonium sulfate [NH4Fe (SO4) 212H2O] or chromic potassium alum [KCr (SO4) 212H2O] or nitre Acid decorations magnesium [Ce2Mg3 (NO3) 1214H2O] etc..
The operation principle and process of the utility model:
In use, external screw joint is connected on drilling rod, bottom connection drill bit, drilling rod drives inner tube and drill bit to turn Dynamic, centralizer can make sampler keep stable state in shaft bottom and outer basket is kept to turn not with the rotation of inner tube It is dynamic.After rock core enters inner tube, due to inner tube with outer basket respectively by common basket and magnetic basket Composition, so when outer magnetic basket is turned to interior common basket the same side, between inner tube and outer basket The paramagnetism salt of filling is magnetized just in magnetic field in annular gap, and (magnetic entropy subtracts for the magnetic order degree reinforcement of paramagnetism salt It is small), externally release heat, liberated heat is diffused into drilling fluid, with circulation of drilling fluid to well outside;Outer tube is rotated further, suitable For magnetic salt gradually in the state of no magnetic field, magnetic order degree declines (magnetic entropy increase), absorbs heat from inner tube again, And the heat absorbed comes from the rock core being taken, the temperature of rock core reduces, and obtains effectively Cord blood.
The beneficial effects of the utility model:
This keeps the temperature Sampling driller for polar region moral purity and the magnetic refrigeration tubular type of land permafrost region Gas Hydrate Drilling, no It can only act on using liquid in the bore flushing medium of circulatory mediator, to may also function as using gas as drilling circulatory mediator In the environment of, during core-drilling effect protrude, it is pollution-free, for gas hydrates and the occurrence condition of moral purity, to moral purity It is small with the primordial condition disturbance of gas hydrates.

Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the principle structure schematic diagram one of the utility model.
Fig. 3 is the principle structure schematic diagram two of the utility model.
Specific embodiment
It please refers to Fig.1, shown in Fig. 2 and Fig. 3, the utility model provides one kind for polar region moral purity and land permafrost region day The magnetic refrigeration tubular type heat preservation Sampling driller of right gas hydrate probing, one kind are hydrated for polar region moral purity and land permafrost region natural gas The magnetic refrigeration tubular type heat preservation Sampling driller of object probing, mainly by both arms drilling rod 7, rolling bearing 2, interior magnetic basket 51, outer magnetic Property basket 62, interior common basket 52, outer common basket 61, separator 9, composition.Wherein both arms drilling rod 7 is by inner tube 5 and outer basket 6 form, and inner tube 5 is made of interior magnetic basket 51 and interior common basket 52, outer basket 6 by Outer common basket 61 and outer magnetic basket 62 form;Inner tube 5 and outer basket 6 are connected by rolling bearing 2, the axis of rolling 2 are held to be located on bearing spider 4.During normal drilling inner tube 5 is kept with drilling rod drill bit to be driven to rotate, and outer basket 6 is not It rotates, centralizer 3 can keep the stabilization of Sampling driller;
Paramagnetism salt mainly has:Ferriammonium sulfate [NH4Fe (SO4) 212H2O], chromic potassium alum [KCr (SO4) 212H2O], Nitric acid decorations magnesium [Ce2Mg3 (NO3) 1214H2O] etc..
The operation principle and process of the utility model:
It please refers to Fig.1, shown in Fig. 2 and Fig. 3, in use, external screw joint 1 is connected on drilling rod, connection drill bit in bottom bores Bar drives inner tube 5 and drill bit to rotate, and centralizer 3 can make sampler keep stable state in shaft bottom and keep outer rock core Pipe 6 is not rotated with the rotation of inner tube 5.After rock core enters inner tube 5, due to inner tube 5 and outer basket 6 It is made of respectively common basket and magnetic basket, so when outer magnetic basket 62 is turned to interior common basket 52 together During one side, the paramagnetism salt 8 of filling is just in magnetic field in the annular gap between inner tube 5 and outer basket 6, by magnetic To change, the magnetic order degree of paramagnetism salt 8 strengthens (magnetic entropy reduction), externally releases heat, and liberated heat is diffused into drilling fluid, Outside with circulation of drilling fluid to well;Outer tube is rotated further, and gradually in the state of no magnetic field, magnetic order degree declines paramagnetism salt (magnetic entropy increase) absorbs heat from inner tube again, and the heat absorbed comes from the rock core being taken, the temperature drop of rock core It is low, obtain effectively Cord blood.
