Abstract
The utility model provides a rock core computed tomography (CT) scanning fixing device which comprises a base, a rock core rear top head and a rock core front top head; the base is arranged on a scanning bed; the position of the base is determined through the coordinate of an entering position of the CT scanning bed, and the base is fixed on the scanning bed through a fixing bolt; a groove for containing a rock core sample is arranged on the base, and the groove is in parallel with the axial direction of the scanning bed; the stainless rock core rear top head is vertically fixed on one end of the base, and is vertical to the groove; an axial slide rail is arranged on the base; the rock core front top head is in parallel with the rock core rear top head, is connected with the slide rail in a sliding way, and can axially slide on the base; an axial ruler for marking the position of the rock core sample is arranged on the base, and a push-pull fixing handle is arranged on the rock core front top head; and the device facilitates the taking, placing and the fixing of the CT scanning rock core and ensures the accurate axial positioning of a plurality of times of CT scanning, the structure is simple, and the operation is convenient and quick.
Description
Technical field
The utility model relates to a kind of CT scan stationary installation, is specifically related to be applicable to the axial accurate positioning device when various types of rock cores carry out CT scan.
Background technology
CT technical development very fast, as measuring technology conventional in the core analysis, aspects such as the nonuniformity that is widely used in core description, rock core is measured, the core sample handling procedure is determined, the measurement of crack quantitative test, online saturation degree, flowing experiment research.
The ultimate principle of CT scan rock is: the X-ray beam that CT machine internal X-ray pipe produces from a plurality of directions along object certain selected tomography aspect shine, the X ray amount that sees through by mensuration, organize the absorption coefficient of constituent parts volume through calculating this aspect after the digitizing, these absorption coefficients can constitute different character matrixs; Carry out digital-to-analog conversion by high-speed computer in the machine, can show on screen or take photos, the image of reconstruction can also provide each pixel X ray attenuation coefficient, uses the CT value representation usually.
Because the complicated component of rock wants computing rock skeleton CT to count CT
GrainNeed know the mineralogical composition and the composition of each fault surface of rock, this obviously is to be difficult to realize, so CT commonly used measures the method for rock porosity, usually need scanning method two times, after being about to dry rock scanning, with scanning again behind rock 100% saturated liquid, try to achieve the rock sample factor of porosity again by calculating.
The factor of porosity of computing rock no matter, or the saturation degree of Fluid Computation, all need several different state of rock core is scanned, and how to guarantee that rock core also becomes a key index of CT scan core analysis at same position (particularly axial location) under these several states.
Localization method at present commonly used is that rock core is placed in the clamper, carries out after the scanning of dried rock core that saturated liquid scans again in clamper.This method is more loaded down with trivial details, needs to consider the CT decay of core holding unit and gum cover, and consuming time long, can't carry out large batch of test.In addition if to the injury of formation rock research, as the variation of rock before and after the acidifying etc., the method is just infeasible.
The utility model content
The purpose of this utility model provides a kind of rock core CT scan locating device that can carry out accurate axial location to rock core, thereby realizes the CT that the injury of rock porosity, fluid saturation or rock etc. is carried out is accurately and fast measured or characterizes.
A kind of rock core CT scan stationary installation described in the utility model by base, rock core after the top, come directly towards before the rock core and constitute; Base be positioned over scanning bed on, by the position that the bed position coordinate is determined base of advancing of CT scan bed, and with set bolt be fixed in scanning bed on; Base is provided with the groove that is used to place core sample, and this groove is parallel to scanning bed axial direction; Come directly towards behind the stainless rock core, vertically be fixed on an end of base, and perpendicular to groove; Base is provided with axial slide rail; Come directly towards after the top is parallel to rock core before the rock core, and be slidingly connected, can on base, do endwisely slipping with slide rail; Base is provided with the axial scale that indicates the core sample position, and the top is provided with the push-and-pull fixed handle before the rock core.
When laying rock core, the push-and-pull fixed handle on the top before the pulling rock core makes the preceding top of rock core towards sliding away from the direction that comes directly towards behind the rock core earlier, rock core is put into groove, promote top before the rock core then, make top before the rock core, rock core after the top clamp rock core, write down the scale of axial scale.By the location of advancing bed position coordinate and the axial scale of core sample of CT scan bed, can carry out accurate localization to the scanning of core sample under different conditions.
The beneficial effects of the utility model are that taking, putting of CT scan rock core and fixing is convenient in the design of top and scale before the slidably rock core of the present utility model, guaranteed the repeatedly accurate axial location of CT scan.It is simple in structure, and is easy to operate, quick.
