Description

Technical Field

[0001] The utility model relates to the technical field of oil well logging, in particular to an on-site non-hydrocarbon detector for oil well logging. Background Art

[0002] In oil logging operations, the comprehensive application of various technical methods such as rock and mineral analysis, geophysics, and geochemistry to carefully observe, collect, collect, record, and analyze solid, liquid, and gas media returned from the wellbore during drilling is a key step in constructing logging geological profiles, identifying oil and gas shows, evaluating oil and gas layer quality, and providing key drilling information to oil engineering. The accuracy of this process directly depends on the accurate detection of the returned material composition.

[0003] To meet this demand, a Chinese patent with publication number CN217180797U discloses an on-site non-hydrocarbon detector for oil logging. The non-hydrocarbon detector uses a timer to perform timing work, and then uses a PLC controller and relay to periodically start multiple hydrogen sulfide sensors and carbon monoxide sensors to work simultaneously, thereby improving the accuracy of on-site detection data. The detection data is then sent to a remote control terminal through a signal transceiver, and the concentration of harmful gases in the construction site is then detected through a harmful gas detector.

[0004] In practical applications, such non-hydrocarbon detectors face two significant challenges: first, after long-term operation, the filter on the air inlet tends to accumulate a large amount of dust, which not only affects the efficiency of gas sample collection but may also interfere with the test results; second, if the moisture that may be carried in the gas sample is not properly handled, it will directly threaten the performance and life of the detection element, increase maintenance costs and reduce detection accuracy.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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

[0029] Figure 1 This is a schematic cross-sectional view of a non-hydrocarbon detector for oil well logging in one embodiment of the present utility model; Figure 2 for Figure 1 A in the middle is an enlarged structural diagram; Figure 3 This is a schematic diagram of the three-dimensional structure of an on-site non-hydrocarbon detector for oil well logging according to one embodiment of the present utility model; Figure 4 This is a schematic diagram of the back view of a non-hydrocarbon detector for oil well logging in one embodiment of the present invention. Figure 1-4 As shown, according to one embodiment of the present invention, a non-hydrocarbon detector for oil well logging comprises a box body 1 and a detector body 207 disposed inside the box body 1, wherein the box body 1 is provided with an air inlet 8 at the bottom and an air outlet 211 at the top;

[0030] The non-hydrocarbon detector further comprises: an adsorption mechanism 2;

[0031] The main body of the adsorption mechanism 2 is arranged inside the box body 1. The adsorption mechanism 2 is movably connected to the box body 1. The air entering the air inlet 8 contacts the detector body 207 after passing through the adsorption mechanism 2. The adsorption mechanism 2 is used to filter and dry the gas inside the box body 1.

[0032] In this embodiment, the box body 1 of the oil well logging field non-hydrocarbon detector serves as the main structure, and an air inlet 8 is provided at the bottom to introduce the gas to be detected, while an air outlet 211 is provided at the top for the treated gas to be discharged. Inside the box body 1, the core detector body 207 is properly placed to detect the non-hydrocarbon components of the treated gas. What is particularly critical is that the adsorption mechanism 2, as the core component of gas pretreatment, is also arranged inside the box body 1, but is movably connected to the box body 1. This design facilitates the disassembly, assembly and maintenance of the adsorption mechanism 2. When external air enters the box body 1 through the air inlet 8, it will first pass through the adsorption mechanism 2. The built-in filter, desiccant and other components of the mechanism will filter and dry the gas to ensure that the gas entering the detector body 207 is pure and dry, thereby improving the accuracy and stability of the detection.

[0033] This new device integrates a highly efficient adsorption mechanism to fully filter and dry the gas before it enters the detector, effectively removing impurities and moisture from the air and providing high-quality sample gas for subsequent non-hydrocarbon component detection. This new device not only improves detection accuracy and reliability, but also extends the lifespan of the detector and reduces maintenance costs. Furthermore, the flexible connection between the adsorption mechanism and the housing makes assembly, disassembly, and maintenance of the device more convenient and efficient, further enhancing the overall user experience.

[0034] According to one embodiment of the present invention, the adsorption mechanism 2 includes: a connecting plate 201, a positioning plate 203, and a support plate 204; the connecting plate 201 and the support plate 204 are arranged parallel to the surface of the positioning plate 203;

[0035] The surface of the connecting plate 201 is provided with a filter 202 for filtering the gas;

[0036] A placement groove 205 is provided on the surface of the support plate 204 , and a desiccant 206 is provided on the surface of the placement groove 205 ; the desiccant 206 is used to dry the gas.

[0037] In this embodiment, the adsorption mechanism 2 includes a connecting plate 201, a positioning plate 203 and a support plate 204. The connecting plate 201 and the support plate 204 are in a parallel state, and they are both firmly fixed to the same surface of the positioning plate 203. Specifically, one end of the connecting plate 201 and the support plate 204 are respectively fixedly connected to one side of the positioning plate 203. This connection method not only ensures the stability of the structure, but also enables the entire adsorption mechanism to maintain good balance and consistency during operation. The surface of the connecting plate 201 is provided with a filter 202 for filtering the gas; the surface of the support plate 204 is provided with a placement groove 205, and the surface of the placement groove 205 is provided with a desiccant 206; the desiccant 206 is used to dry the gas. Preferably, the air entering from the air inlet 8 at the bottom of the box body 1 is filtered by the filter 202, dried by the desiccant 206, and then contacts the detector body 207.

[0038] The adsorption mechanism of this utility model achieves efficient gas filtration and drying. The filter screen installed on the connecting plate effectively intercepts and filters impurities and particulate matter in the gas, improving gas purity. The desiccant filled in the placement slot on the support plate further dries the gas, removing moisture and humidity, thereby ensuring the dryness of the output gas. This utility model's integrated filtering and drying design greatly improves the efficiency and effectiveness of gas treatment, meeting the high gas quality requirements of various industrial and daily life fields.

[0039] According to one embodiment of the present invention, a baffle 208 is hingedly connected to the surface of the placement groove 205 via a hinge, and a ventilation hole 209 is opened on the surface of the baffle 208; a positioning block 7 for supporting the baffle 208 is provided on the surface of the placement groove 205.

[0040] In this embodiment, in order to manage the desiccant 206 more flexibly and conveniently, the design of the placement slot 205 has been further optimized. Specifically, a baffle 208 is hinged to the surface of the placement slot 205 via a hinge. This connection method allows the baffle 208 to rotate freely around the hinge, thereby easily opening or closing the opening of the placement slot 205. In addition, in order to maintain the stability of the baffle 208 during use, positioning blocks 7 are also provided on the surface of the placement slot 205. These positioning blocks can serve as support points. When the baffle 208 is rotated to the closed position, it contacts and fixes the baffle 208, thereby ensuring that the baffle 208 tightly covers the placement slot 205. At the same time, air vents 209 are specially opened on the surface of the baffle 208. These air vents allow gas to pass through, ensuring that when the baffle is closed, the gas can still come into contact with the desiccant 206 and be effectively dried.

[0041] The adsorption mechanism of the present invention not only realizes dual treatment of gas (filtration and drying), but also further improves the convenience and practicality of operation: the hinged design of the baffle and the placement slot makes it simple and quick to replace or check the desiccant without completely disassembling the entire adsorption mechanism; the addition of air holes ensures that the gas can still circulate when the baffle is closed, ensuring that the drying effect is not affected; the setting of the positioning block enhances the stability of the baffle, preventing it from accidentally opening during operation, and further improving the safety and reliability of the entire adsorption mechanism.

[0042] According to one embodiment of the present invention, a through hole 210 for the connecting plate 201 and the supporting plate 204 to pass through is opened on one side of the box body 1, and a sliding groove for supporting the connecting plate 201 and the supporting plate 204 is opened on the inner surface of the box body 1.

[0043] In this embodiment, the box body 1 serves as the primary load-bearing structure of the adsorption mechanism, and its design fully considers the installation and stability of the connecting plate 201 and the support plate 204. Specifically, through-holes 210 are cleverly provided on one side of the box body 1. The size and position of these through-holes 210 have been precisely calculated to ensure that the connecting plate 201 and the support plate 204 can smoothly pass through and be fixed inside the box body. At the same time, the inner surface of the box body 1 is also provided with chute grooves, which tightly fit the edges of the connecting plate 201 and the support plate 204, providing them with a stable support platform. Through the guiding effect of the chute grooves, the connecting plate 201 and the support plate 204 can remain parallel and stable inside the box body, thereby ensuring the stable operation of the entire adsorption mechanism.

[0044] The utility model realizes the stable installation and support of the connecting plate and the support plate inside the box body through the ingenious combination of the through hole and the slide groove, which not only improves the overall structural strength of the adsorption mechanism, but also simplifies the installation process and improves the use efficiency.

[0045] According to one embodiment of the present invention, a first magnet 3 is provided on the side of the positioning plate 203 that contacts the box body 1, and a second magnet 4 is provided on the outer surface of the box body 1 at a position corresponding to the first magnet 3, and the first magnet 3 and the second magnet 4 match.

[0046] Preferably, a sealing rubber pad 5 is further provided on the positioning plate 203 , and the sealing rubber pad 5 and the first magnet 3 are located on the same side of the positioning plate 203 ; when the adsorption mechanism 2 is connected to the box body 1 , the sealing rubber pad 5 fits the outer surface of the box body 1 .

[0047] Preferably, sealing rubber pads 5 are provided on the upper and lower edges of the positioning plate 203 , and the first magnet 3 is provided between the connecting plate 201 and the positioning plate 203 .

[0048] In this embodiment, the connection between the adsorption mechanism 2 and the box body 1 has been further optimized and strengthened. Specifically, the positioning plate 203, which serves as the support base for the connecting plate 201 and the support plate 204, is cleverly provided with a first magnet 3 on the side that contacts the box body 1. Simultaneously, a second magnet 4 is provided on the outer surface of the box body 1, corresponding to the position of the first magnet 3. These two sets of magnets match each other, and through magnetic force, they securely attach the positioning plate 203 to the box body 1, effectively preventing the positioning plate 203 from sliding or falling off within the box body.

[0049] To further enhance the sealing performance of the connection, sealing rubber pads 5 are added to the positioning plate 203. These sealing rubber pads 5 and the first magnet 3 are located on the same side of the positioning plate 203. When the adsorption mechanism 2 is tightly connected to the box body 1, the sealing rubber pads 5 will naturally adhere to the outer surface of the box body 1, forming an effective sealing barrier.

[0050] To ensure a comprehensive sealing effect, sealing rubber pads 5 are provided on the upper and lower edges of the positioning plate 203. At the same time, the first magnet 3 is provided between the connecting plate 201 and the positioning plate 203, which does not affect the transmission of magnetic force and ensures the compactness of the overall structure.

[0051] This utility model significantly improves the connection stability and sealing performance between the adsorption mechanism and the box body by introducing a magnetic connection mechanism between the first and second magnets and a sealing rubber gasket. The magnetic connection not only simplifies installation but also ensures connection reliability. The addition of the sealing rubber gasket effectively prevents gas leakage and other problems, further enhancing the overall performance and safety of the device.

[0052] According to one embodiment of the present invention, a transverse plate 212 is provided on the inner surface of the box body 1 , and a fan 213 is installed on the surface of the transverse plate 212 . By turning on the fan 213 , gas is driven to enter the box body 1 through the air inlet 8 .

[0053] Preferably, the transverse plate 212 is disposed between the connecting plate 201 and the supporting plate 204 .

[0054] In the present embodiment, the internal structure of the box body 1 is further optimized. Specifically, a horizontal plate 212 is cleverly provided on the inner surface of the box body 1, and the horizontal plate is located between the connecting plate 201 and the support plate 204, forming a partition space. Such a layout not only optimizes the space utilization inside the box body, but also provides a solid foundation for the subsequent installation of the fan 213. On the surface of the horizontal plate 212, a fan 213 is installed, and the fan 213 is connected to the power supply via an electric wire, which can be controlled to open and close. When the fan 213 is turned on, it will generate a strong airflow, sucking the outside gas into the interior of the box body 1 through the air inlet 8. This design allows the gas to enter the box body 1 smoothly and effectively through the air inlet 8, providing the necessary power support for the subsequent gas processing steps.

[0055] The utility model significantly improves the efficiency and flexibility of gas treatment by arranging a horizontal plate and installing a fan in the box body; the introduction of the fan enables the gas to actively and continuously enter the box body, avoiding the problems of poor air intake or insufficient air intake that may exist in the traditional passive air intake method; the arrangement of the horizontal plate not only stabilizes the installation position of the fan, but also optimizes the spatial layout inside the box body, making the entire gas treatment process smoother and more efficient.

[0056] According to an embodiment of the present invention, the plurality of air outlet holes 211 are arranged at an angle, and filter plates 6 are provided on the surfaces of the plurality of air outlet holes 211 .

[0057] In this embodiment, the design of the box body 1 further reflects the dual considerations of gas treatment efficiency and cleanliness. Specifically, a plurality of air outlets 211 are arranged on the side wall or top of the box body 1. These air outlets are not simply opened vertically or horizontally, but are arranged in an inclined manner. This inclined design not only helps to guide the treated gas to be discharged from the box body more smoothly, but more importantly, it significantly reduces the possibility of external dust or impurities entering the box body in reverse through the air outlet. In addition, a filter plate 6 is installed on the surface of each air outlet 211. These filter plates 6 are made of fine mesh material, which can further block the passage of tiny particles and ensure that the gas discharged from the air outlet is purer. The filter plate 6 is tightly connected to the air outlet 211 through a fixed structure at the edge, forming a barrier that is both breathable and dustproof.

[0058] The utility model effectively improves the dust-proof performance of the gas treatment equipment by arranging the gas outlet holes at an angle and equipping them with filter plates, ensures the cleanliness of the discharged gas, promotes the smooth discharge of the gas, and improves the overall work efficiency.

[0059] According to one embodiment of the present invention, a clamping plate 9 is provided on the outer surface of the box body 1 , and the clamping plate 9 is used to fix the box body 1 to a fixed surface. The surface of the clamping plate 9 is provided with anti-slip grooves 10 .

[0060] In this embodiment, the design of the box body 1 fully considers its practicality and convenience. In order to more flexibly fix the box body 1 to various fixed surfaces (such as walls, workbenches, and even clothes, etc.), a splint 9 is cleverly provided on the outer surface of the box body 1. The splint 9 serves as a bridge connecting the box body and the fixed surface. Its shape and size are carefully designed to ensure that it can fit closely to different types of installation surfaces. The edges of the splint 9 on both sides may have a buckle or elastic clamping structure, so that the user can easily clamp the splint on the mounting plate, or clamp it on the edge of a clothing pocket, etc. In addition, in order to enhance the stability of the clamping and prevent slipping, anti-slip grooves 10 are also deliberately provided on the surface of the splint 9. These anti-slip grooves 10 effectively increase the friction between the splint 9 and the fixed surface by increasing the surface roughness, and can maintain a stable connection even in a dynamic environment.

[0061] The utility model greatly improves the flexibility and stability of the box body installation by providing a clamping plate with anti-slip grooves, allowing users to easily fix the box body to various fixed surfaces as needed, making both fixed installation and temporary clamping more convenient and efficient.

[0062] Example 2

[0063] like Figure 1-4 As shown, according to an embodiment of the present invention, a non-hydrocarbon detector for oil logging site is provided, comprising a box body 1, an adsorption mechanism 2 is provided inside the box body 1, the adsorption mechanism 2 comprises a connecting plate 201, a filter screen 202 is provided on the surface of the connecting plate 201, a positioning plate 203 is connected to one end of the connecting plate 201, a surface of the positioning plate 203 is also connected to a support plate 204, a placement groove 205 is provided on the surface of the support plate 204, a desiccant 206 is provided on the surface of the placement groove 205, a detector body 207 is provided inside the box body 1, a baffle 208 is hinged to the surface of the placement groove 205 by a hinge, an air vent 209 is provided on the surface of the baffle 208, a plurality of air outlet holes 211 are provided on the surface of the box body 1, an air inlet 8 is provided at the bottom of the box body 1, a horizontal plate 212 is provided on the surface of the box body 1, and a fan 213 is installed on the surface of the horizontal plate 212.

[0064] In this embodiment, the gas can be filtered by setting a filter 202 to avoid affecting the detection results. The desiccant 206 can be set to absorb the moisture inside the box body 1. The baffle 208 can protect the desiccant 206. The moisture enters the placement groove 205 through the air hole 209 and is absorbed by the desiccant 206. The fan 213 can drive the gas to enter the box body 1 through the air inlet 8, and the gas is detected by the detector body 207 and then discharged from the air outlet 211.

[0065] The utility model effectively improves the accuracy and stability of the non-hydrocarbon detector in the oil well logging field by integrating functions such as filter filtration, desiccant dehumidification, baffle protection and fan circulation gas, ensures the accuracy of the detection results, and extends the service life of the equipment.

[0066] Example 3

[0067] like Figure 1-4 As shown, according to one embodiment of the present invention, a non-hydrocarbon detector for oil well logging includes a box body 1, an adsorption mechanism 2 is provided inside the box body 1, and the adsorption mechanism 2 includes a positioning plate 203, and a connecting plate 201 and a support plate 204 are connected to the positioning plate 203;

[0068] The surface of the box body 1 is provided with a through hole 210 for the connecting plate 201 and the support plate 204 to pass through. The inner surface of the box body 1 is provided with a slide groove for supporting the connecting plate 201 and the support plate 204. The surface of the positioning plate 203 is provided with a first magnet 3. The surface of the box body 1 is provided with a second magnet 4. The first magnet 3 and the second magnet 4 match. The surface of the positioning plate 203 is provided with a sealing rubber pad 5, which is in contact with the box body 1.

[0069] A plurality of air outlet holes 211 are provided on the surface of the box body 1, and the plurality of air outlet holes 211 are arranged at an angle, and a filter plate 6 is provided on the surface; a placement groove 205 is provided on the surface of the support plate 204, and a positioning block 7 for supporting the baffle 208 is provided on the surface of the placement groove 205; a splint 9 is provided on the outer surface of the box body 1, and an anti-slip pattern 10 is provided on the surface of the splint 9.

[0070] In this embodiment, by providing a sliding groove on the inner surface of the box body 1, the connecting plate 201 and the support plate 204 can be supported. By setting the first magnet 3 and the second magnet 4, the positioning plate 203 can be positioned to prevent the positioning plate 203 from driving the connecting plate 201 and the support plate 204 to slide out of the box body 1. The provided sealing rubber pad 5 can seal the box body 1 to improve the sealing performance. By setting the air outlet 211 at an angle, the entry of dust into the air outlet 211 can be reduced. By setting the positioning block 7, the baffle 208 can be supported. The provided splint 9 can facilitate the installation of the box body 1.

[0071] The utility model improves the stability and ease of use of the non-hydrocarbon detector and ensures the cleanliness and accuracy of the detection environment through designs such as slide support, magnetic positioning, sealing rubber pads to enhance sealing, inclined air outlets to reduce dust entry, positioning block support baffles, and anti-slip splints for easy installation.

[0072] Working principle of this utility model:

[0073] Clip the clamping plate 9 onto the mounting plate or onto a pocket of clothing. When in use, the fan 213 drives external air into the box body 1. The air is filtered by the filter 202 to remove larger particles such as dust from the air. The filtered air moves upward and passes through the detector body 207 for detection. The detected air is then discharged from the box body 1 through the air outlet 211.

[0074] By pulling the positioning plate 203, the positioning plate 203 drives the connecting plate 201 and the supporting plate 204 to move outward, at which time the filter 202 can be cleaned, and by rotating the baffle 208, the internal desiccant 206 can be replaced;

[0075] After the connecting plate 201 and the supporting plate 204 are inserted into the through hole 210 , the first magnet 3 and the second magnet 4 are attracted to each other to prevent the connecting plate 201 and the supporting plate 204 from sliding out.

[0076] The wiring diagram of the fan 213 and the detector body 207 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring layout of the fan 213 and the detector body 207 are no longer explained in detail.

[0077] This new device uses a fan to drive the air through a filter before testing, and then discharges it through the inclined air outlet, ensuring detection accuracy and internal cleanliness. Furthermore, the convenient assembly and disassembly design facilitates filter cleaning and desiccant replacement, and the magnetic positioning ensures that the adsorption mechanism is stable and does not fall off. The overall design improves detection efficiency and ease of operation.
