Abstract
In order to solve using during miniature CT scan rock core, scanner distorsion and later period CT data processing difficulty phenomenon caused by due to rock core clamping verticality is not high, the present invention provides a kind of new CT Scan orientation devices, rock core is fixed using the screw of four groups of different directions, to guarantee that rock core relative scanning camera lens is in accurate plumbness.Its primary structure are as follows: rock core positioning tube, positioning screw, pedestal.Before CT scan, the fixation hole of pedestal bottom end is first matched into fixation with the convex of scanning platform buckle；Equally, then by the fixation hole of rock core positioning tube bottom end with the convex on pedestal top buckle fixation is matched；Finally rock core is put into positioning tube, is hammered into shape using vertical line and the core sample verticality in positioning tube is detected in all angles, by constantly adjusting length of four pairs of positioning screws in rock core positioning tube, rock core is finally made to be in plumbness.
Description
Technical field
It is that one kind carries out essence to core sample when can be used for miniature CT scan the present invention relates to minitype CT scanning device field
The clamping device of true perpendicular positioning can fix rock core and be in plumbness and then scan the good CT image of acquisition.
Background technique
In recent years, CT scan technology is widely used in both at home and abroad in oil reservoir development research, has pushed the skill of permeation fluid mechanics
Art progress is scanned CT imaging by the core sample to different lithology, can get true, accurate, intuitive reservoir rock
Stone pore structure characteristic.Research and application at present in this respect is concentrated mainly on image analysis level, that is, utilizes CT image meter
Density, porosity, the saturation degree etc. of core sample are calculated, while qualitative retouch is made to the distribution of fluid in micropore structure and hole
It states and quantitative measurment.
During using CT scan rock core, since rock core places inaccuracy vertically, it be easy to cause because of scan image not
Vertically there is the phenomenon that artifact, and heterogeneous fluid displacement specificity analysis determining to post analysis rock core physical parameter generates larger
Error.Therefore, it is necessary to a kind of minitype CT Scan orientation devices, rock core are accurately vertically fixed on scanning pony sill, thus
Guarantee the CT scan for carrying out core sample high quality, and then guarantee the present invention relates to minitype CT scanning device field, is a kind of
Can be used for core sample being carried out when miniature CT scan the standard of the clamping device later period CT data processed result of precise perpendicularity positioning
True property.
Summary of the invention
In order to solve using during miniature CT scan rock core, due to rock core clamping verticality is not high caused by scan image
Distortion and later period CT data processing difficulty phenomenon, the present invention provides a kind of new CT Scan orientation devices, utilize four groups of differences
Rock core is fixed in the screw in direction, to guarantee that rock core relative scanning camera lens is in accurate plumbness.
The novel micro- CT scan positioning device of one kind that the present invention designs, primary structure are as follows: rock core positioning tube (1), positioning
Screw (2), pedestal (3).
The device entirety and its part are that circumference is symmetrical, and rock core positioning tube (1) is made by pmma material, just
In position observation, and obvious loss will not be caused to CT ray；Positioning screw (2) is made of polyether-ether-ketone resin material, equally
Obvious loss will not be caused to CT ray；Pedestal (3) is made by stainless steel material.(1) four positive direction of rock core positioning tube
Respectively there is a pair of of threaded hole at place, for being coupled four pairs of positioning screws (2)；Positioning tube bottom end also has there are three fixation hole, with pedestal (3)
On three convexs buckle match, for horizontal fixed rock core positioning tube (1).Four pairs of positioning screws (2) are adjusted by rotation
Length in rock core positioning tube (1) can reach the effect for adjusting rock core vertical state.Pedestal (3) bottom end equally has and rock
Identical three fixation holes in heart positioning tube (1) bottom end, for horizontal fixed whole device in CT scanner bracket.

Specific embodiment
Before CT scan, the fixation hole of pedestal (3) bottom end is first matched into fixation with the convex of scanning platform buckle；Equally,
The fixation hole of rock core positioning tube (1) bottom end is matched into fixation with the convex on pedestal (3) top buckle again；It is fixed that finally rock core is put into
In the cylinder of position, is hammered into shape using vertical line and the core sample verticality in positioning tube is detected in all angles, by constantly adjusting four
To length of the positioning screw (2) in rock core positioning tube (1), rock core is finally made to be in plumbness.
The foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
