Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1-Figure 5 , the existing portable oil logging device is inconvenient to lift the device when in use. In order to solve this technical problem, this embodiment discloses the following technical content;

[0029] A portable oil logging device includes a base box 1, a motor 2, a pulley 3, a transmission belt 4, a screw 5, a limiting rod 6, a storage box 7, a first support column 8, a second support column 9, a handle 10, a box cover 11, a display screen 12, a fluorescent logging unit 13, a storage drawer 14, a chip collection groove 15, a magnetic plate 16, a spring 17, a rubber plate 18, and a baffle 19.

[0030] A roller 20 is fixed to the lower surface of the bottom box 1, and a handle 10 is fixed to the left end of the upper surface of the bottom box 1. When carrying the oil logging device, the staff can hold the handle 10 and move the device under the action of the roller 20, which is convenient for carrying;

[0031] The lifting mechanism includes a motor 2, a pulley 3, a transmission belt 4, a screw 5, a limiting rod 6, a first support column 8 and a second support column 9. The first support column 8 and the second support column 9 are both fixedly connected to the storage box 7. The motor 2 is fixed inside the bottom box 1, and the pulley 3 is fixed to the output end of the motor 2. The transmission belt 4 is provided on the outside of the pulley 3. The screw 5 is fixed on the upper surface of the pulley 3. The limiting rod 6 is fixed on the upper surface of the bottom box 1. The outer end of the screw 5 is threadedly connected to the first support column 8. The second support column 9 is provided on the outside of the limiting rod 6. The first support column 8 forms a lifting structure with the bottom box 1 through the screw 5;

[0032] The fluorescent mud logger 13 proposed in this application has the same working principle as the fluorescent mud logger proposed in the authorization announcement number CN211148439U. Since the fluorescent mud logger 13 is a common technology on the market, it will not be described in detail again. When the fluorescent mud logger 13 needs to be used, the motor 2 inside the lifting mechanism is turned on, and the motor 2 drives the pulley 3 and the transmission belt 4 to rotate clockwise, thereby driving the two sets of screw rods 5 to rotate simultaneously, and the first support column 8 threadedly connected to the screw rod 5 is raised, thereby raising the second support column 9 and the storage box 7. A limiting rod 6 runs through the interior of the second support column 9, and the moving trajectory of the storage box 7 is limited by the limiting rod 6. By raising the storage box 7, the fluorescent mud logger 13 can be lifted, which is convenient for the staff to use;

[0033] A storage box 7 is provided above the bottom box 1. A cover 11 is installed on the top of the storage box 7 through a hinge. A display screen 12 is fixed on the inner side of the cover 11. A fluorescent logging device 13 is fixed inside the storage box 7.

[0034] When testing is required, the box cover 11 is flipped over to expose the display screen 12 on the box cover 11 and the fluorescent mud logger 13. The rock cuttings to be tested are placed in the sample slot inside the fluorescent mud logger 13. The fluorescent light source illuminates the surface of the sample and reflects the fluorescence, which is captured by the detector. After amplification by the amplifier and the single-chip microcomputer, the oil content image of the rock cutting layer is displayed on the display screen 12.

[0035] Example 2: Please refer to Figure 1、 Figure 2 and Figure 4 The existing portable oil logging device can store different rock cuttings through multiple chip collecting grooves 15. However, it is not convenient to limit the rock cuttings when storing them. The rock cuttings may collide and move when the device is moved. In order to solve this technical problem, the present embodiment discloses the following technical content;

[0036] A storage drawer 14 is provided below the fluorescent logging instrument 13. The storage drawer 14 is connected to the storage box 7 in a card slot connection. Chip collecting grooves 15 are evenly provided inside the storage drawer 14. A limiting mechanism is installed inside the chip collecting groove 15.

The right end of the storage box 7 is rotatably connected with a baffle 19. The storage drawer 14 is limited to the inside of the storage box 7 by the baffle 19. The rock cuttings are put into the inside of the chip collecting groove 15. The rock cuttings are located on the inner sides of the two sets of rubber plates 18. The rock cuttings are limited by the spring 17 and the rubber plate 18 to avoid collision between the rock cuttings and the chip collecting groove 15 when the device is moved.

[0037] Insert the storage drawer 14 into the storage box 7, and then rotate the baffle 19 so that the outer end of the baffle 19 blocks the outer side of the storage drawer 14, and the storage drawer 14 is defined by the baffle 19;

[0038] Example 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 2. When the limiting mechanism is not needed to limit the rock chips, it is inconvenient to remove the limiting mechanism. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1 、 Figure 2 and Figure 4 As shown; the components inside the storage drawer 14 for constituting the chip collecting groove 15 are made of iron, and the magnetic plate 16 is magnetically connected to the components inside the storage drawer 14 for separating the chip collecting groove 15. When the limiting mechanism is not needed, the magnetic plate 16 can be taken out from the inside of the chip collecting groove 15. The above completes a series of operations of the portable oil logging device. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
