Description

Technical Field

[0001] This utility model relates to a multi-component detection device for logging, belonging to the technical field of logging detection equipment. Background Technology

[0002] Well logging is a process that uses methods such as rock and mineral analysis, geophysics, and geochemistry to observe, collect, and record information on solid, liquid, and gaseous materials returned from the wellbore during the drilling process. This information is used to establish well logging geological profiles, discover oil and gas shows, evaluate oil and gas reservoirs, and provide drilling information services for petroleum engineering.

[0003] During well logging, the detection of multi-component gases is an important aspect, contributing to oil and gas discovery and drilling safety. However, this detection requires the gas to be introduced into the detection device through a gas delivery pipe. Since the diameter of the delivery pipe is fixed, only devices with that specific diameter can be connected to it, reducing the device's versatility. Therefore, we provide a multi-component detection device for well logging to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a multi-component detection device for logging, the specific technical solution of which is as follows:

[0005] A multi-component detection device for logging includes a housing body, a storage box installed inside the housing body, an air supply pipe connected inside the storage box, a tapered tube connected inside the air supply pipe, a sealing gasket fitted on the outer surface of the tapered tube, a positioning block connected to the outer surface of the air supply pipe, a threaded rod rotatably connected inside the positioning block, a transmission plate rotatably connected to the outer surface of the threaded rod, and a limit clamp connected to one end of the transmission plate.

[0006] Preferably, a fixing plate is connected inside the outer shell body, and a transport pipe is installed inside the fixing plate, with the bottom end of the transport pipe connected to the inside of the storage box.

[0007] Preferably, a gas detector is mounted on the upper surface of the fixing plate, and the top end of the transport pipe is connected to the interior of the gas detector.

[0008] Preferably, the gas detector has a transmission tube inside, and a support frame is connected to the outer surface of the fixing plate, with the inside of the support frame engaging with the outer surface of the transmission tube.

[0009] Preferably, an exhaust gas treatment device is installed on the upper surface of the fixing plate, and the end of the transmission pipe away from the gas detector is connected to the interior of the exhaust gas treatment device.

[0010] Preferably, the exhaust gas treatment device has an exhaust pipe connected to its interior, and the outer surface of the exhaust pipe is connected to the interior of the outer casing.

[0011] Preferably, the outer surface of the transmission plate is slidably connected to the interior of the positioning block, the outer surface of the limiting clamp is slidably connected to the interior of the positioning block, and the outer surface of the limiting clamp is slidably connected to the interior of the air supply pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This multi-component detection device for logging, through the cooperation of components such as a tapered tube and a limiting clamp, allows pipes smaller than the gas delivery pipe diameter to be fitted onto the surface of the tapered tube. This allows the gas transmitted from these pipes to enter the receiving box through the tapered tube, ensuring that pipes smaller than the gas delivery pipe diameter can completely deliver gas into the receiving box without leakage. The limiting clamp is movable, and by moving the limiting clamp, it clamps the pipes fitted onto the surface of the tapered tube, thus restricting the position of these pipes and preventing them from changing. This is very convenient and solves the problem of limited devices that can be connected to the gas delivery pipe and low versatility.

[0014] 2. This multi-component detection device for logging uses components such as sealing gaskets and barrier blocks. The sealing gasket is fitted onto the surface of the tapered tube. When pipes of different sizes are connected to the tapered tube, the sealing gasket will block between the pipe and the tapered tube, thereby increasing their sealing performance. The barrier block can restrict the position of the transfer tube. By connecting the barrier block to the transfer tube, the position of the transfer tube is restricted, preventing the transfer tube from shaking. It is very easy to use. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 - Figure 5 It includes an outer shell 1, inside which a storage box 2 is installed. Inside the storage box 2, a gas supply pipe 3 is connected. The outer shell 1 restricts the position of the storage box 2, preventing it from moving. The storage box 2 restricts the position of the gas supply pipe 3. The gas to be detected can be sent into the storage box 2 through the gas supply pipe 3, and the storage box 2 distributes these gases.

[0023] The gas supply pipe 3 is internally connected to a tapered pipe 4, and a sealing gasket 5 is fitted on the outer surface of the tapered pipe 4. The gas supply pipe 3 fixes the position of the tapered pipe 4, preventing it from moving. The tapered pipe 4 allows pipes with a smaller diameter than the gas supply pipe 3 to be connected to it, thereby increasing the adaptability of the device. When other pipes are connected to the tapered pipe 4 through the sealing gasket 5, gas will not leak out between the sealing gasket 5 and the tapered pipe 4.

[0024] The outer surface of the air supply pipe 3 is connected to a positioning block 6, and the inside of the positioning block 6 is rotatably connected to a threaded rod 7. The air supply pipe 3 will fix the position of the positioning block 6, so that the positioning block 6 cannot move. The positioning block 6 will restrict the movable position of the threaded rod 7, thereby reducing the vibration generated when the threaded rod 7 rotates, so that the threaded rod 7 can only rotate within the positioning block 6 and cannot move laterally.

[0025] A transmission plate 8 is rotatably connected to the outer surface of the threaded rod 7. One end of the transmission plate 8 is connected to a limit clamp 9. When the threaded rod 7 rotates, the transmission plate 8 can move laterally, allowing the user to adjust the position of the transmission plate 8 by rotating the threaded rod 7. The transmission plate 8 will fix the position of the limit clamp 9. When the transmission plate 8 moves, it will move the limit clamp 9 with it. By moving the limit clamps 9 on both sides, the pipes that are connected to the tapered tube 4 are clamped, thereby restricting the position of these pipes and preventing them from moving.

[0026] The outer shell 1 has a fixing plate 10 inside, and a transport tube 11 is installed inside the fixing plate 10. The bottom end of the transport tube 11 is connected to the inside of the storage box 2. The outer shell 1 will fix the position of the fixing plate 10 so that the fixing plate 10 cannot move. There are two fixing plates 10. The fixing plates 10 will restrict the position of the transport tube 11 so that the transport tube 11 will not shake.

[0027] A gas detector 12 is mounted on the upper surface of the fixing plate 10. The top end of the transport pipe 11 is connected to the inside of the gas detector 12. The fixing plate 10 restricts the position of the gas detector 12, preventing it from moving arbitrarily. By connecting the transport pipe 11 to the inside of the gas detector 12, the transport pipe 11 transfers the gas in the storage box 2 to the gas detector 12. Multiple gas detectors 12 are mounted on the fixing plate 10.

[0028] The gas detector 12 has a transmission tube 13 inside, and a support column 14 is connected to the outer surface of the fixing plate 10. The gas detector 12 restricts the position of the transmission tube 13, and the gas inside the gas detector 12 can be discharged through the transmission tube 13. The fixing plate 10 fixes the position of the support column 14, making the support column 14 unable to move.

[0029] One end of the support column 14 is connected to a blocking block 15. The inside of the blocking block 15 is engaged with the outer surface of the transmission tube 13. The support column 14 will fix the position of the blocking block 15, so that the blocking block 15 cannot move. The blocking block 15 is used to hold the transmission tube 13 in place, thereby limiting the position of the transmission tube 13 and preventing the transmission tube 13 from shaking.

[0030] An exhaust gas treatment device 16 is installed on the upper surface of the fixing plate 10. One end of the transfer pipe 13 away from the gas detector 12 is connected to the inside of the exhaust gas treatment device 16. The other fixing plate 10 restricts the position of the exhaust gas treatment device 16, preventing it from moving. The transfer pipe 13 sends the gas in the gas detector 12 into the exhaust gas treatment device 16, where the exhaust gas treatment device 16 performs harmless treatment on the gas.

[0031] The exhaust gas treatment device 16 has an exhaust pipe 17 connected inside. The outer surface of the exhaust pipe 17 is connected to the inside of the outer shell 1. The exhaust gas treatment device 16 restricts the position of the exhaust pipe 17. The exhaust gas treated by the exhaust gas treatment device 16 is discharged from the device through the exhaust pipe 17. The outer shell 1 also restricts the position of the exhaust pipe 17.

[0032] The outer surface of the transmission plate 8 is slidably connected to the interior of the positioning block 6, the outer surface of the limiting clamp 9 is slidably connected to the interior of the positioning block 6, and the outer surface of the limiting clamp 9 is slidably connected to the interior of the air supply pipe 3. The positioning block 6 restricts the direction in which the transmission plate 8 can move, thereby preventing the position of the transmission plate 8 from deviating. The positioning block 6 and the air supply pipe 3 restrict the direction in which the limiting clamp 9 can move.

[0033] The gas detector 12 and the exhaust gas treatment device 16 in this application are common electrical devices in the prior art, and this application will not elaborate on their models or internal structures.

[0034] In use, this invention first requires connecting the pipeline carrying the gas to be tested to the sealing gasket 5 on the surface of the tapered tube 4. After the pipeline and the sealing gasket 5 are in close contact, the user needs to rotate the threaded rod 7 to move the transmission plate 8. The movement of the transmission plate 8 will cause the limiting clamp 9 to clamp the pipeline, thereby limiting various types of pipelines. Then, the pipeline can send the gas into the storage box 2. The gas in the storage box 2 is sent to the gas detector 12 by the transport pipe 11 for gas detection. After the gas detection is completed, the gas in the gas detector 12 can be sent to the exhaust gas treatment device 16 by the transfer pipe 13. After being processed by the gas detector 12, it is discharged by the exhaust pipe 17.
