Description

Technical Field

[0001] This utility model relates to a sonar fracturing monitoring device, specifically a novel sonar fracturing monitoring device, belonging to the field of oil and gas extraction engineering technology. Background Technology

[0002] In the process of fracturing oil and gas extraction, sonar monitoring technology is widely used to monitor the fracture propagation state and fracturing fluid flow. At the fracturing site, sonar monitoring probes often face harsh working environments, and impurities such as mud, proppant particles and oil carried in the fracturing fluid are easily attached to the probe surface.

[0003] Existing sonar fracturing monitoring devices lack self-cleaning capabilities. Contaminants on the probe surface severely affect the transmission and reception of sonar signals, leading to attenuation of echo signal strength and a significant decrease in the accuracy and reliability of monitoring data. This, in turn, affects the judgment and evaluation of fracturing operation effectiveness, reducing the overall effectiveness of the sonar fracturing monitoring device. Therefore, a novel sonar fracturing monitoring device is proposed here. Utility Model Content

A sonar monitoring body is fixedly connected to the bottom surface of the auxiliary shell, and the sonar monitoring body is located inside the protective cover. Multiple sets of equally spaced sound holes are opened on the outer surface of the protective cover. A liquid storage chamber is opened inside the auxiliary shell, and an auxiliary water pump is installed inside the liquid storage chamber. The outlet end of the auxiliary water pump is fixedly connected to a main water pipe. Three multi-nozzle nozzles are fixedly connected to the inner wall of the protective cover. A water delivery pipe is fixedly connected to the upper surface of each multi-nozzle nozzle. The end of each water delivery pipe closest to the main water pipe passes through the protective cover and the auxiliary shell in sequence and is fixedly connected to the main water pipe. The auxiliary shell is equipped with a cleaning component.

[0006] The liquid storage chamber is fixedly connected to a one-way valve, the top of which penetrates the auxiliary shell and extends to the top of the auxiliary shell.

[0007] A reinforcing ring is fixedly connected to the outer surface of the one-way valve, and the top end of the reinforcing ring is fixedly connected to the inner top wall of the liquid storage chamber.

[0008] A drain pipe is fixedly connected to the bottom surface of the protective cover, and a solenoid valve is fixedly connected to the outer surface of the drain pipe.

[0009] An installation plate is fixedly connected to the outer surface of the auxiliary shell, and multiple equally spaced fixing bolts are threaded onto the inside of the installation plate.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0017] Please see Figures 1-4 This utility model provides a novel sonar fracturing monitoring device, including an auxiliary shell 1, and a self-cleaning mechanism 2 is provided inside the auxiliary shell 1; The self-cleaning mechanism 2 includes a protective cover 201. The upper surface of the protective cover 201 is fixedly connected to the bottom surface of the auxiliary shell 1. A sonar monitoring body 202 is fixedly connected to the bottom surface of the auxiliary shell 1. The sonar monitoring body 202 is located inside the protective cover 201. Multiple sets of equally spaced sound holes 203 are opened on the outer surface of the protective cover 201. A liquid storage chamber 204 is opened inside the auxiliary shell 1. A one-way valve 4 is fixedly connected inside the liquid storage chamber 204. The top of the one-way valve 4 penetrates through the auxiliary shell 1 and extends to the top of the auxiliary shell 1. The one-way valve 4 can provide a convenient liquid inlet position for the liquid storage chamber 204, increasing the convenience of adding cleaning fluid to the liquid storage chamber 204, and also preventing the cleaning fluid in the liquid storage chamber 204 from spilling out.

[0018] An auxiliary water pump 205 is installed inside the liquid storage chamber 204. A reinforcing ring 5 is fixedly connected to the outer surface of the one-way valve 4. The top of the reinforcing ring 5 is fixedly connected to the inner top wall of the liquid storage chamber 204. The reinforcing ring 5 can increase the fixed connection area between the one-way valve 4 and the liquid storage chamber 204, making the connection between the two more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the service life of the device.

[0019] The outlet of the auxiliary water pump 205 is fixedly connected to the main water pipe 206, the bottom surface of the protective cover 201 is fixedly connected to the drain pipe 6, and the outer surface of the drain pipe 6 is fixedly connected to the solenoid valve 7. The drain pipe 6 can discharge the clean water after cleaning inside the protective cover 201, and the solenoid valve 7 can control the connection status of the drain pipe 6, increasing the convenience of the device during use.

[0020] The inner wall of the protective cover 201 is fixedly connected with three multi-nozzle nozzles 207, and the outer surface of the auxiliary shell 1 is fixedly connected with a mounting plate 8. The mounting plate 8 has multiple equally spaced fixing bolts 9 connected to its internal threads. With the cooperation of the mounting plate 8 and the fixing bolts 9, the auxiliary shell 1 can be quickly fixed, which increases the convenience of installation and improves the effect during use.

[0021] The mounting plate 8 has a placement groove 10 inside, and a sealing gasket 11 is installed inside the placement groove 10. The placement groove 10 and the sealing gasket 11 work together to effectively increase the sealing effect after the auxiliary shell 1 is connected, avoid leakage at the connection, and improve safety during mining.

[0022] Each multi-nozzle nozzle 207 has a fixed water delivery pipe 208 connected to its upper surface. Each water delivery pipe 208 has a end near the main water pipe 206 that passes through the protective cover 201 and the auxiliary shell 1 and is fixedly connected to the main water pipe 206. The outer surface of the auxiliary water pump 205 is fixedly connected to a support block 12. The bottom surface of the support block 12 is fixedly connected to the inner bottom wall of the liquid storage chamber 204. The support block 12 serves to fix the auxiliary water pump 205, providing a good force-bearing position for the auxiliary water pump 205, increasing the stability of the auxiliary water pump 205 during use, and improving the sensitivity of the device. The auxiliary housing 1 is equipped with a cleaning component 3, which includes two electric telescopic rods 301. The outer surface of each electric telescopic rod 301 is fixedly connected to the inner wall of the auxiliary housing 1. The telescopic ends of the two electric telescopic rods 301 are fixedly connected to scrapers 302. The inner wall of each scraper 302 is in contact with the outer surface of the protective cover 201. The power generated by the electric telescopic rods 301 drives the scrapers 302 to move up and down. During the movement, the scrapers 302 can continuously scrape the protective cover 201, thereby scraping off the impurities adhering to its surface, effectively increasing the stability of the protective cover 201 during operation.

[0023] When using this utility model: First, connect the sonar monitoring body 202, auxiliary water pump 205, electric telescopic rod 301 and solenoid valve 7 to the power supply. Then, add cleaning fluid to the liquid storage chamber 204 using the one-way valve 4. Install it in a suitable position using the mounting plate 8 and fixing bolts 9. The sealing gasket 11 can increase the sealing effect after installation. Then, monitor the sonar monitoring body 202. During the monitoring process, the protective cover 201 and the sound passage 203 can protect the sonar monitoring body 202 and prevent large impurities from entering the protective cover 201 and affecting the operation of the sonar monitoring body 202. When further cleaning of the sonar monitoring body 202 is required, the auxiliary water pump 205 is started. The suction generated by the auxiliary water pump 205 is used to transfer the cleaning fluid in the storage chamber 204 to the main water pipe 206. Then, multiple water delivery pipes 208 guide the fluid to the multi-nozzle nozzle 207. The multi-nozzle nozzle 207 then sprays high-pressure water evenly onto the sonar monitoring body 202 to wash away impurities adhering to the surface of the multi-nozzle nozzle 207, preventing contaminants from affecting the transmission and reception of sonar signals. At the same time, the solenoid valve 7 is opened, so that the cleaned wastewater is discharged from the protective cover 201 through the drain pipe 6. When it is necessary to clean the contaminants on the surface of the protective cover 201, the electric telescopic rod 301 is activated. The thrust generated by the electric telescopic rod 301 pushes the scraper 302 to move. As the scraper 302 moves, it continuously rubs against the protective cover 201, thereby cleaning the contaminants on the surface of the protective cover 201. This prevents the contaminants from clogging the sound passage 203, further increasing the stability of the sonar monitoring body 202 during operation and improving the applicability of the sonar fracturing monitoring device.
