Description
Technical field
The invention belongs to petrophysical parameter test and analysis technology field more particularly to a kind of rock NMR instrument samples
Carry bed and its application method.
Background technology
In recent years, nuclear magnetic resonance technique due to detection speed is fast, to sample nondestructive, result is accurate the advantages that become interior
The conventional means of petrophysical parameter test, especially in blowhole measures analysis, Magnetic resonance imaging test increasingly
Favored.When being tested using rock NMR instrument, need rock sample being placed on strip arc groove first
It carries on bed, then will carry bed and sample is put into coil box together, coil box connects circuit and is placed in magnetic field, and then completes
Nuclear magnetic resonance is tested.Due to generally requiring that multiple testing procedure is carried out to same sample in experimentation, to obtain difference
Condition, the nuclear magnetic resonance image test result of different time, then compare and analyze.And existing sample carries bed and test side
Often there are errors for method, are mainly manifested in：Load bed is strip arc groove, and rock sample is cylinder, and the diameter for usually carrying bed is bigger
In the diameter of rock sample, therefore rock sample is placed on and carries on bed, easy to roll, it is impossible to ensure that sample is placed on load bed axis during test every time
Same position on direction.Therefore, because sample is placed on the spatial position difference carried on bed, after leading to different testing procedures
The nuclear magnetic resonance image result of acquisition is variant, is unfavorable for intuitively being compared, affects the analysis of nuclear magnetic resonance test result.
Invention content
The technical problems to be solved by the invention be to provide it is a kind of it is easy to operate, quick, data result comparability is strong
Rock NMR instrument sample carry bed and its application method.
In order to solve the above technical problems, rock NMR instrument sample provided by the invention carries bed, including carrying bed ontology, institute
It states and carries bed ontology and be equipped with strip arc groove, scale and number of division are identified in an axial direction at one side edge in the strip arc groove
Word, the strip arc groove is interior to be equipped in the graduated side of mark and can slide item in axial sliding along strip arc groove, institute
It states a sliding bottom end face and extends to strip arc groove bottom center, and the vertical plane where with strip arc groove bottom centerline
It overlaps, diameter spirit bubble is equipped at strip arc groove one end bottom center.
Further, be equipped with axially extending guide groove in the strip arc groove, the sliding item be equipped with it is described
The guide pad that guide groove matches.
Further, the sliding item is arc-shaped and is close to the strip arc groove, the top of the sliding item and institute
It is concordant to state strip arc groove top end face.
Correspondingly, the application method that bed is carried the invention also discloses a kind of rock NMR instrument sample (utilizes and includes this
Carry the method that the Nuclear Magnetic Resonance of bed tests rock), setting-out marks one on the end face of cylinder rock sample one end first
Diameter line；Cylinder rock sample is placed in strip arc groove, slides sliding item against cylinder rock sample, and ensure to mark
The rock diameter line of note is located at the bottom end face institute of sliding item planar, and records number of division；The load bed of rock sample will be mounted with
Ontology is put into the coil box in Nuclear Magnetic Resonance, is tested, and ensures that the bubble in diameter spirit bubble is placed in the middle during test.
The present invention is suitable for carrying out the test of cylinder rock sample using rock NMR instrument, realize it is easy to operate,
Fast, the purpose of data result comparability is strong.
The invention has the advantages that when being tested using rock NMR instrument, by scale, slider bar by rock sample
Fixed placement records specific number of division on bed is carried；By diameter spirit bubble come ensure carry bed be to lie in a horizontal plane in coil
In box, it is identical for can ensure that spatial position of the same sample in different measuring process, so as to the nuclear magnetic resonance figures to acquisition
As comparing and analyzing.
In conclusion the present invention is a kind of to carry out same cylinder rock sample in different test steps using rock NMR instrument
There is easy to operate, quick and strong data result comparability rock NMR instrument sample to carry bed and test side under the conditions of rapid
Method.
