Description
Technical field
The present invention relates to a kind of probe for rock core gamma ray detection.
Background technology
Core gamma survey instrument is mainly used in oilfield prospecting developing field, and it can on-the-spotly in the wild be got drilling well
The core gone out carries out the measurement of gamma ray value fast, and result is printed.So both improve the accuracy that gamma value is measured, also greatly shorten the work period simultaneously, increase work efficiency, reduce detection cost.
Core gamma survey instrument forms primarily of travelling belt, gamma-ray probe, computer and printer.Wherein gamma-ray probe has been mainly used in measuring the gamma value of whole core.
Existing gamma-ray probe is primarily of compositions such as scintillation crystal, photomultiplier, circuit board and aluminum pipes.Wherein scintillation crystal is mainly used in gathering gamma-rays, sends computer to after photomultiplier conversion increases signal by circuit board 5.Because photomultiplier 3 is very frangible, this brings trouble just to assembling gamma-ray probe, and we need a kind of method can be relatively fixing by the position of scintillation crystal, photomultiplier, consider that it mutually can not collide and make photomultiplier broken again.
Summary of the invention
In order to solve the problem, the object of the invention is to improve existing core gamma-ray probe, making it install safer, assemble more convenient.For achieving the above object, the present invention takes following technical scheme to realize:
A kind of probe for rock core gamma ray detection, comprise the aluminum pipe (7) as shell, fixing therein for gathering gamma-ray scintillation crystal (1), photomultiplier (3) and circuit board (5), scintillation crystal (1) is fixed on the front portion of aluminum pipe (7), photomultiplier (3) is fixed therein portion, it is characterized in that, pad (2) is provided with between scintillation crystal (1) and photomultiplier (3), sleeve (4) is provided with between photomultiplier (3) and circuit board (5), sleeve (4) middle part is provided with through wires hole (11), sleeve (4) is divided into front and back two parts, front portion is divided into photomultiplier fixed card slot (10), rear portion is divided into the circular draw-in groove (9) of circuit board, the rear portion of photomultiplier (3) is fixed in photomultiplier fixed card slot (10), circuit board is fixed in the circular draw-in groove (9) of circuit board.
The present invention is owing to taking above technical scheme, and it has the following advantages:
(1) the present invention is on the basis of existing core gamma-ray probe, adds polyurethane pad 2, both simply, also solves owing to installing photomultiplier 3 fragmentation caused accidentally simultaneously.
(2) owing to adding polytetrafluoro sleeve 4 on existing core gamma-ray probe, both the fixing of scintillation crystal 1, photomultiplier 3 and circuit board 5 relative position had been facilitated, also facilitate the taking-up of photomultiplier 3 simultaneously, make convenient, the simple and safety of the assembly and disassembly of core gamma-ray probe.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is rock core gamma-ray probe structural representation.
Fig. 2 is the structural representation of polytetrafluoro sleeve 4.
Scintillation crystal 1 in figure, 2. polyurethane pad, 3. photomultiplier, 4. polytetrafluoro sleeve, 5. circuit board, 6. aviation plug, 7. aluminum pipe, 9. circuit board circular draw-in groove, 10. photomultiplier fixed card slot, 11. through wires holes.
Embodiment
See Fig. 1 and Fig. 2, the present invention is applicable on core gamma survey instrument, and improved gamma-ray probe is primarily of compositions such as scintillation crystal 1, photomultiplier 3, circuit board 5, polyurethane pad 2, polytetrafluoro sleeve 4 and aluminum pipes 7.Wherein scintillation crystal 1 is mainly used in gathering gamma-rays, and photomultiplier 3 sends computer to by 7. circuit boards after changing increase signal.
Concrete implementation method is as follows: after polyurethane pad 2 being put into the heavy caliber of aluminum pipe 7, respectively scintillation crystal 1 and photomultiplier 3 are put into from the two ends of aluminum pipe 7 respectively again, finally the photomultiplier fixed card slot 10 of polytetrafluoro sleeve 4 pushed down photomultiplier 3 and circuit board 5 be embedded in the circular draw-in groove 9 of circuit board of polytetrafluoro sleeve 4, finally the end cap at aluminum pipe 7 two ends being compressed.
