[0002] The development of the petroleum industry has placed increasing demands on monitoring and metering technologies used in oilfield production processes. During oilfield operations, the pressure of oil and gas inside pipelines is a crucial parameter for assessing production status, predicting equipment failures, and optimizing extraction efficiency. Traditional pressure sensors are often installed directly inside the pipelines, which not only increases installation difficulty and maintenance costs but also makes them susceptible to corrosion from corrosive substances in the oil and gas medium, affecting the sensor's stability and service life. Furthermore, in complex and changing oilfield environments, especially those that are humid, dusty, or contain corrosive gases, the sensor's waterproof and sealing properties become critical factors in ensuring its reliable operation.

[0003] Although there are many waterproof pressure sensors on the market, sensors designed for the special environment of oil fields still need to be improved in terms of waterproof performance, sealing, installation convenience and adaptability. Especially in the field of virtual metering, how to achieve accurate monitoring of the external pressure of the oil pipeline while taking into account waterproofness, sealing, easy installation and adjustability has become a technical problem that the industry needs to solve. Therefore, the development of a new waterproof pressure sensor for oil field virtual metering is of great significance to improving the safety, reliability and efficiency of oil field production. Therefore, in response to the above technical problems, a waterproof pressure sensor for oil field virtual metering is proposed here. Utility Model Content

[0021] 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.

[0022] Example 1

[0023] See also Figure 1-5 The utility model proposes a waterproof pressure sensor for virtual metering in oil fields, comprising a device body 1 and an oil pipe 2. An arcuate groove 3 is provided on the outside of the device body 1, which can be adapted to the oil pipe 2. An opening 4 is provided on the outside of the oil pipe 2. A cavity 5 is provided on the inside of the device body 1. A plurality of groups of waterproof gaskets 6 arranged at equal intervals are fixedly connected to the outside of the arcuate groove 3. The waterproof gasket 6 can prevent the oil-gas mixture in the oil pipe 2 from entering the cavity 5. A circuit board 10 is fixedly connected to the inside of the cavity 5. A sensor 11 is fixedly connected to the upper side of the circuit board 10. The sensor 11 corresponds to the position of the waterproof gasket 6. A pressure detection mechanism is installed inside the waterproof gasket 6.

[0024] The sensor 11 is the most important component in the pressure sensor. Its main function is to convert the pressure signal into other forms of signals, such as electrical signals. The sensor is the core of the pressure sensor. It is in direct contact with the measured medium and senses the changes in pressure.

[0025] The arc-shaped groove 3 covers the oil pipe 2 in all directions, which can effectively prevent oil and gas leakage in the oil pipe 2.

[0026] The pressure detection mechanism includes a mounting tube 7, a telescopic rod 8 and a gasket 9. The mounting tube 7 is mounted against the inside of the waterproof gasket 6, the telescopic rod 8 is slidably connected to the inside of the mounting tube 7, and the gasket 9 is fixedly connected to both sides of the telescopic rod 8.

[0027] A signal processor 12 is fixedly connected to the interior of the cavity 5 , and an electrical conductor 13 is fixedly connected between the signal processor 12 and the circuit board 10 . Signals are connected between the signal processor 12 and the circuit board 10 via the electrical conductor 13 .

[0028] A sealing strip 14 is fixedly connected to the outside of the arc-shaped groove 3 , and the sealing strip 14 is located on both sides of the opening 4 .

[0029] The working principle of a waterproof pressure sensor for oilfield virtual metering based on the first embodiment is as follows: when in use, the pressure sensor is installed on the outside of the oil pipe 2, and the arc groove 3 covers the opening 4 opened on the outside of the oil pipe 2. When oil and gas pass through the inside of the oil pipe 2, pressure is generated on the inner wall of the oil pipe 2, thereby squeezing the gasket 9 on the outside of the telescopic rod 8, so that the telescopic rod 8 can be extended and retracted inside the mounting tube 7. The gasket 9 inside the telescopic rod 8 will contact and squeeze with the sensor 11, and then the pressure signal is transmitted to the signal processor 12. The pressure inside the oil pipe 2 is intuitively displayed through data, and by providing multiple sets of telescopic rods 8, the pressure changes at the opening 4 can be dynamically detected, so that the transportation status of oil and gas inside the oil pipe 2 can be intuitively understood. During the oil and gas pressure detection process inside the oil pipe 2, the presence of the waterproof gasket 6 can prevent oil and gas from entering the cavity 5 through the gap. At the same time, the sealing strips 14 on the left and right sides of the arc-shaped groove 3 can prevent the oil and gas mixture from leaking to the outside through the gap between the oil pipe 2 and the device body 1, thereby achieving better waterproof performance and improving the sealing performance.

[0030] Example 2

[0031] See also Figure 1-7 Based on the first embodiment, the bottom of the device body 1 is detachably connected to the bottom plate 15, and the two sides of the bottom plate 15 are fixedly connected to the mounting base 16. The upper side of the mounting base 16 is fixedly connected to the first clamping plate 17, and the upper side of the mounting base 16 is rotatably connected to the second clamping plate 18. The first clamping plate 17 and the second clamping plate 18 are symmetrically installed, and the inner sides of the first clamping plate 17 and the second clamping plate 18 are both provided with semicircular grooves. The outside of the second clamping plate 18 is fixedly connected to a spring 22, and the end of the spring 22 is fixedly connected to a hook 23. The outside of the first clamping plate 17 is fixedly connected to a hanging ring 24, and the hanging ring 24 and the hook 23 are detachably connected.

[0032] A mounting groove 19 is provided on the upper side of the mounting seat 16, and a fixing rod 20 is fixedly connected to the inside of the mounting groove 19. A rotating block 21 is rotatably connected to the outside of the fixing rod 20, and the rotating block 21 is fixedly connected to the bottom of the second splint 18. By rotating the rotating block 21 around the fixing rod 20, the first splint can be driven to rotate, thereby changing the distance between the first splint and the second splint.

[0033] In this embodiment, when connecting this device to the oil pipe 2, first, the first clamping plate 17 is brought into contact with one side of the oil pipe 2. Since the semicircular groove is provided on the outside of the first clamping plate 17, it can be adaptively connected to the oil pipe 2. Then, the arc groove 3 is aligned with the opening 4 provided on the outside of the oil pipe 2 for fitting connection. Then, the first clamping plate 17 is rotated so that the first clamping plate 17 and the second clamping plate 18 clamp the oil pipe 2. The hook 23 on the outside of the spring 22 is connected to the hanging ring 24, and the clamping between the device and the oil pipe 2 is completed. If it is necessary to adjust the pressure between the first clamping plate 17 and the second clamping plate 18 according to the vibration generated during the oil and gas transportation in the oil pipe 2 and the hardness and strength of the oil pipe 2 itself, the pressure between the first clamping plate 17 and the second clamping plate 18 can be changed by changing the number of hooks 23 and hanging rings 24, thereby changing the number of connecting springs 22, so as to adjust the force that is most suitable for clamping. On the one hand, it can prevent the oil pipe 2 from being unstable in installation due to vibration, and on the other hand, it can also prevent the outer wall of the oil pipe 2 from being damaged by excessive clamping pressure.
