Description

Technical Field

[0001] This utility model relates to the field of logging detection equipment, specifically a fluorescent logging instrument. Background Technology

[0002] Well logging is primarily used for oil and gas resource assessment. This involves using various measuring instruments during oil and gas drilling operations to acquire real-time data reflecting various aspects of the well, including downhole geological structure, oil and gas content, and drilling details. Fluorescent logging equipment is a crucial well logging instrument. For example, patent CN1306147C discloses a comprehensive well logging system and method for petroleum geological exploration. This comprehensive well logging system includes equipment such as a chromatograph, fluorescence analyzer, and geochemical analyzer.

[0003] However, existing fluorescent logging equipment generally suffers from complex structures. For example, patent CN202102126U discloses a high-resolution cuttings image acquisition instrument, which requires a material tray motor and other devices to control the movement of the material tray, thereby enabling it to cooperate with the image acquisition device for data acquisition. Another example is patent CN203981563U, which discloses a white light and fluorescence logging device for cuttings, utilizing a sample basket and a closed chain drive to continuously and automatically scan the white light and fluorescence image information of the cuttings sample.

[0004] In addition, practical use has revealed the following drawbacks of traditional fluorescent logging equipment:

[0005] 1. Traditional fluorescence logging equipment usually cannot adjust the intensity of fluorescence and white light as needed, which can easily lead to observational errors;

[0006] Second, some samples exhibit extinction effects, thus requiring the addition of appropriate chemical reagents before fluorescence imaging. However, traditional fluorescence logging equipment necessitates removing the sample, adding liquid, and then placing it back into the equipment, a relatively cumbersome process. Furthermore, operators typically need to make adjustments and related operations based on sample observations, but current technology only allows adjustment via a front door, making observation and adjustment inconvenient.

[0007] Third, the observation holes on traditional fluorescent logging equipment are prone to light leakage, which in turn affects the imaging effect. Utility Model Content

[0008] The purpose of this invention is to provide a fluorescence logging instrument that utilizes the adjustment of visible light source intensity and fluorescence source intensity in conjunction with the autofocus function of an autofocus camera to ensure clear sample observation, while further simplifying the structure and making operation more convenient.

[0009] The objective of this utility model is achieved through the following technical solution:

[0010] A fluorescence logging instrument includes a housing, with an autofocus camera at the upper end of the housing, and a visible light source and a fluorescence source inside, wherein the fluorescence source is located below the autofocus camera, and the visible light source is symmetrically located on both sides of the fluorescence source; a control panel is located at the lower end of the housing, and the control panel has a visible light adjustment knob and a fluorescence adjustment knob; a front door is located on the front side of the housing, and side doors are located on both sides; in addition, an observation window that allows only visible light to pass through is located at the upper front end of the housing, and the observation window is covered with a cover plate.

[0011] The housing is equipped with an adjustment tooling plate, and the adjustment tooling plate has multiple positioning holes distributed in a matrix. The adjustment tooling plate is also equipped with multiple limiting blocks. The material tray is placed on the adjustment tooling plate and its displacement is limited by each limiting block. The limiting blocks are fixed to the corresponding positioning holes by positioning bolts.

[0012] The limiting block includes a vertical limiting part and a horizontal connecting part. The limiting part abuts against the material tray, and the connecting part is provided with a locking groove. Two positioning bolts are provided in the locking groove and their lower ends are respectively connected to the corresponding positioning holes on the adjusting tooling plate.

[0013] The lower end of the front door is rotatably connected to the outer shell via a front door hinge, the upper end of the front door is provided with an adsorption magnet, and the outer side of the front door is provided with a front door handle.

[0014] The lower end of the housing is provided with a base, and the control panel is provided on the front side of the base.

[0015] In addition to the visible light adjustment knob and the fluorescence adjustment knob, the control panel also includes a camera button, a visible light switch button, and a fluorescence switch button. The base contains a camera control module, a visible light control module, and a fluorescence control module. The autofocus camera and the camera button are connected to the camera control module via corresponding first wires. The visible light source, the visible light adjustment knob, and the visible light switch button are connected to the visible light control module via corresponding second wires. A fluorescence generating device is located at the upper end of the housing, and the front end of the fluorescence generating device forms the fluorescence source. The fluorescence generating device, the fluorescence adjustment knob, and the fluorescence switch button are connected to the fluorescence control module via corresponding third wires.

[0016] The top of the housing includes a front tilted portion, a horizontal portion, and a rear tilted portion connected in sequence, wherein the observation window is disposed on the front tilted portion, the autofocus camera is disposed on the horizontal portion, and the fluorescence generating device is disposed on the rear tilted portion.

[0017] The cover plate is in the shape of a groove.

[0018] The advantages and positive effects of this utility model are as follows:

[0019] 1. When using this utility model, the operator can adjust the intensity of the visible light source by adjusting the visible light adjustment knob, adjust the intensity of the fluorescent light source by adjusting the fluorescence adjustment knob, and then use an autofocus camera to automatically focus in order to determine whether the sample on the tray is clear.

[0020] 2. When using this utility model, sample observation is achieved through the coordination of visible light intensity adjustment, fluorescence intensity adjustment, and automatic focusing of the focusing camera. Therefore, the material tray only needs to be finely adjusted on the adjustment tooling plate, without the need for large-scale movement adjustment. That is, there is no need to set up additional devices or structures to drive the movement and adjustment of the material tray, thus further simplifying the equipment structure.

[0021] 3. When using this utility model, if it is necessary to perform relevant operations on the sample, the operator can open the side doors on both sides and put their hands into the outer shell, while observing through the observation window at the upper front of the outer shell. Compared with the prior art, which can only open the front door to observe and operate at the same time, this utility model is more convenient to operate.

[0022] 4. The observation window of this utility model allows only visible light to pass through, and will not cause damage to the human eye. In addition, when this utility model is used for photographic inspection, the observation window is covered by a cover plate, thereby avoiding the influence of ambient light and shadow on the imaging effect.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] like Figures 1-5 As shown, this utility model includes a housing 1, and the upper end of the housing 1 is provided with an autofocus camera 3, and the interior is provided with a visible light source 13 and a fluorescent light source 201, wherein... Figure 5 As shown, the fluorescent light source 201 is located below the autofocus camera 3, and two visible light sources 13 are symmetrically arranged on both sides of the fluorescent light source 201; the lower end of the housing 1 is provided with a control panel 6, and the control panel 6 is provided with a visible light adjustment knob 603 and a fluorescence adjustment knob 604; the front side of the housing 1 is provided with a front door 5, and the sides are provided with side doors 8. In addition, the upper front side of the housing 1 is provided with an observation window 4 that allows only visible light to pass through, and the observation window 4 is provided with a cover plate 401.

[0031] In use, the material tray 10 is fed into the outer shell 1 after the front door 5 is opened. Then, the operator closes the front door 5 and observes the sample on the material tray 10 through the observation window 4. If it is necessary to adjust the sample or add chemical reagents, the operator can open the side doors 8 on both sides and reach into the outer shell 1 to perform the corresponding operations, while observing through the observation window 4. Compared with the corresponding technology where the front door 5 is opened and observation is performed simultaneously, the operation of this utility model is more convenient. In addition, when the operator uses tweezers to select representative samples, or when placing a long core sample into the outer shell 1 for observation and imaging, this can also be achieved by opening the side doors 8. After the material tray 10 is placed into the outer casing 1, the operator can adjust the intensity of the visible light source 13 using the visible light adjustment knob 603 and the intensity of the fluorescent light source 201 using the fluorescence adjustment knob 604. At the same time, the autofocus camera 3 can cooperate with autofocus to determine whether the sample on the material tray 10 is clear. The observation window 4 only allows visible light to pass through and will not cause damage to the human eye. Furthermore, during subsequent photography and testing, this utility model uses a cover plate 401 to cover the observation window 4, thereby avoiding the influence of ambient light and shadow on the imaging effect.

[0032] This invention can, as needed, incorporate a conventional mechanism for adjusting the position of the tray 10 within the outer casing 1. For example, it can utilize a three-dimensional moving stage as described in patent CN209416927U, or a commercially available product such as an electric stage with only X and Y-axis degrees of freedom. However, because this invention achieves sample observation through the coordination of visible light intensity adjustment, fluorescence intensity adjustment, and the autofocus function of the autofocus camera 3, the position of the tray 10 within the outer casing 1 is relatively fixed. It does not require extensive movement adjustments, meaning there is no need for additional devices or structures to drive the tray's movement. The tray 10 can be finely adjusted within the outer casing 1 to meet usage requirements, further simplifying the equipment structure.

[0033] like Figure 3 and Figure 5 As shown, in this embodiment, the housing 1 is provided with an adjustment tooling plate 9 inside, and the adjustment tooling plate 9 has a plurality of positioning holes 901 distributed in a matrix. The adjustment tooling plate 9 is provided with a plurality of limiting blocks 12. The material tray 10 is placed on the adjustment tooling plate 9 and its displacement is limited by each limiting block 12. The limiting block 12 is fixed to the corresponding positioning hole 901 by positioning bolts 11. Each limiting block 12 cooperates with each other to finely adjust the placement position of the material tray 10 according to actual needs.

[0034] like Figure 3 and Figure 5As shown, in this embodiment, the limiting block 12 includes a vertical limiting part 1201 and a horizontal connecting part 1202, wherein the limiting part 1201 abuts against the material tray 10, and the connecting part 1202 is fixed to the adjusting fixture plate 9 by positioning bolts 11. The connecting part 1202 is provided with a locking groove 1203, and two positioning bolts 11 are provided in the locking groove 1203 and their lower ends are respectively connected to the corresponding positioning holes 901 on the adjusting fixture plate 9.

[0035] like Figures 1-2 As shown, in this embodiment, the lower end of the front door 5 is rotatably connected to the outer casing 1 via a front door hinge 501. The upper end of the front door 5 is provided with an adsorption magnet, and the outer side of the front door 5 is provided with a front door handle 502. After the front door 5 is closed, the adsorption magnet adheres to the corresponding side panel of the outer casing 1 to ensure the front door 5 is locked in position. The operator can open the front door 5 by pulling the front door handle 502.

[0036] like Figure 1 As shown, in this embodiment, the side door 8 is a sliding door structure, wherein the outer shell 1 has operation openings on both sides, and the upper and lower outer sides of the operation openings are provided with slide rails, and the upper and lower inner sides of the side door 8 are provided with sliders that cooperate with the corresponding side slide rails. The area of ​​the side door 8 can be larger than the area of ​​the operation opening, so that when the side door 8 is closed, it can completely block the operation opening to prevent light leakage.

[0037] like Figure 1 As shown, in this embodiment, the lower end of the outer casing 1 is provided with a base 7, and the control panel 6 is provided on the front side of the base 7, as shown. Figure 5 As shown, the base 7 has multiple control modules inside.

[0038] like Figure 1 As shown, in this embodiment, in addition to the visible light adjustment knob 603 and the fluorescence adjustment knob 604, the control panel 6 also includes a camera button 601, a USB interface 602, a visible light switch button 605, a fluorescence switch button 606, and a power switch button 607. Figure 5 As shown, in this embodiment, the base 7 is internally equipped with a camera control module, a visible light control module, a fluorescence control module, and a master control module. The autofocus camera 3 and camera button 601 are respectively connected to the camera control module via corresponding first wires. The visible light source 13, visible light adjustment knob 603, and visible light switch button 605 are respectively connected to the visible light control module via corresponding second wires. Figure 1As shown, a fluorescence generating device 2 is provided on the upper end of the outer casing 1, and the front end of the fluorescence generating device 2 forms the fluorescence light source 201. The fluorescence generating device 2, the fluorescence adjustment knob 604, and the fluorescence switch button 606 are respectively connected to the fluorescence control module through corresponding third wires. The camera control module, visible light control module, and fluorescence control module are mainly used to control the autofocus camera 3, the visible light source 13, and the fluorescence light source 201. In addition, the camera control module, visible light control module, fluorescence control module, USB interface 602, and power switch button 607 are respectively connected to the main control module through corresponding fourth wires. The power switch button 607 controls the power on and off of the entire device, and the USB interface 602 can be used to connect to devices such as computers or for data output.

[0039] The camera control module, visible light control module, fluorescence control module, and main control module are all technologies known in the art, and can be implemented by programming or purchased as mature commercial products. Furthermore, the autofocus camera 3 and the fluorescence generator 2 are also commercially available products. The fluorescence generator 2 is equipped with an internal fan that continuously cools the light source, and its outer casing has heat dissipation holes.

[0040] like Figure 1 As shown, in this embodiment, the top of the outer shell 1 includes a front tilted portion 101, a horizontal portion 102 and a rear tilted portion 103 connected in sequence. The observation window 4 is disposed on the front tilted portion 101, the autofocus camera 3 is disposed on the horizontal portion 102, and the fluorescence generating device 2 is disposed on the rear tilted portion 103.

[0041] like Figure 1 As shown, in this embodiment, the cover plate 401 is in the shape of a groove, which can be directly fastened onto the observation window 4.

[0042] In this embodiment, the visible light source 13 is a white light source, and the fluorescent light source 201 is an ultraviolet light source.

[0043] The working principle of this utility model is as follows:

[0044] In use, the material tray 10 is fed into the outer shell 1 after the front door 5 is opened, and placed on the adjustment tooling plate 9. Then, the operator closes the front door 5 and observes the sample on the material tray 10 through the observation window 4. During observation, the operator can adjust the intensity of the visible light source 13 through the visible light adjustment knob 603 and the intensity of the fluorescent light source 201 through the fluorescence adjustment knob 604. At the same time, the autofocus camera 3 cooperates with autofocus to determine whether the sample on the material tray 10 is clear. The observation window 4 only allows visible light to pass through and will not cause damage to the human eye. If the sample needs to be operated, the operator can open the side doors 8 on both sides and put their hands into the outer shell 1. For example, if the sample needs to be adjusted, if relevant chemical reagents need to be added, if the operator needs to use tweezers to select a representative sample, or if the operator needs to put a long core into the shell for observation and imaging, etc. In addition, if the position of the material tray 10 (i.e. the sample position) needs to be finely adjusted, the operator can also do so through the side doors 8 on both sides. When finely adjusting, the operator first removes the positioning bolts 11 on the limiting block 12, and then the limiting block 12 can be moved to adjust the position on the adjusting tooling plate 9. After the position is determined, the positioning bolts 11 on the limiting block 12 are reinserted and fixed to the corresponding positioning holes 901 on the adjusting tooling plate 9.

[0045] After all the relevant operations are completed, the operator can use the corresponding buttons on the control panel 6 to control the present invention to start taking pictures and detecting. The observation window 4 needs to be covered by the cover plate 401 to avoid the ambient light and shadow affecting the imaging effect.
