Description

Technical Field

[0001] This utility model relates to an oil production equipment, and more specifically, to a monitoring device for automatically measuring the dynamic fluid level of multiple oil wells. Background Technology

[0002] Existing manual fluid level testing methods commonly used in oilfields have several drawbacks: First, there's the issue of gas supply. High-pressure nitrogen cylinders are pressure vessels, resulting in high management costs and requiring periodic manual refilling, making continuous automatic operation impossible. Furthermore, prolonged use of compressed air can easily cause casing oxidation and corrosion, and the mixture of air and flammable gases in the well poses an explosion hazard. Second, the installation and disassembly of measuring equipment during dynamic fluid level measurement are complex, wasting manpower and resources and increasing labor intensity. While devices for continuous monitoring of oil well dynamic fluid levels exist in the market, they are generally one-to-one (i.e., one automatic fluid level meter can only test the dynamic fluid level of one oil well). Their cost for widespread application in oilfields is high, and subsequent maintenance costs are also high, resulting in poor economic returns. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic monitoring device for measuring the dynamic fluid level of multiple oil wells to address the aforementioned technical problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic monitoring device for measuring the dynamic fluid level of multiple oil wells is characterized in that the device comprises a central control cabinet and an automatic fluid level tester, wherein the central control cabinet is connected to the automatic fluid level tester via a first connecting line. The central control cabinet is equipped with a touch screen, a PLC controller, and a wireless communication module. The automatic liquid level tester is equipped with an air outlet pipe, a compressor, an air storage tank, and an air inlet pipe in sequence. It also includes a test controller and a microphone, with the test controller controlling the compressor and microphone. The automatic liquid level tester is connected to an array of solenoid valves via a main pipeline and branch pipelines, and the solenoid valves are connected to the corresponding oil wells.

[0005] In a preferred embodiment of the present invention, an air intake filter is provided at the end of the air intake pipe, and an air outlet filter is provided at the end of the air outlet pipe.

[0006] In a preferred embodiment of this utility model, all the solenoid valves are connected to the PLC controller via a second connecting line.

[0007] In a preferred embodiment of this utility model, the monitoring device for automatically measuring the dynamic fluid level of multiple oil wells further includes a remote automatic data platform, which works in conjunction with the central control cabinet.

[0008] Compared with the prior art, the present invention has the following beneficial effects: This invention provides an automatic monitoring device for measuring the dynamic fluid level of multiple oil wells. This device improves the efficiency of dynamic fluid level testing, reduces the labor intensity of employees and the cost of equipment such as automatic fluid level gauges, and enables one automatic fluid level gauge to monitor the dynamic fluid level of multiple wells on a large platform. This effectively improves the efficiency of on-site fluid level monitoring, reduces oxidation and corrosion of downhole casing, realizes remote dynamic fluid level monitoring of multiple oil wells, reduces the risk of hydrogen sulfide leakage, and improves work efficiency and economic benefits.

[0011] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, the automatic monitoring device for measuring the dynamic fluid level of multiple oil wells includes a central control cabinet 100 and an automatic fluid level tester 101. The central control cabinet 100 is connected to the automatic fluid level tester 101 via a first connecting line S.

[0013] The central control cabinet 100 is equipped with a touch screen 1, a PLC controller 3, and a wireless communication module 2.

[0014] The automatic liquid level tester 101 is provided with an air outlet pipe 23, a compressor 26, an air storage tank 29 and an air inlet pipe 28 in sequence. The automatic liquid level tester 101 is also provided with a test controller 25 and a microphone 24. The test controller 25 controls the compressor 26 and the microphone 24.

[0015] The automatic liquid level tester 101 is connected to an array of solenoid valves 4 via the main pipeline 22 and branch pipelines 16. Each solenoid valve 4 is connected to a corresponding oil well 10. Each solenoid valve 4 is connected to the PLC controller 3 via a second connection line K.

[0016] In addition, an intake filter 27 is provided at the end of the intake pipe 28, and an exhaust filter 30 is provided at the end of the exhaust pipe 23.

[0017] In addition, the automatic monitoring device for measuring the dynamic fluid level of multiple oil wells also includes a remote automatic data platform M, which works in conjunction with the central control cabinet 100.

[0018] The following describes the operation of the automatic monitoring device for measuring the dynamic fluid level in multiple oil wells, including the following steps: 1. When the central control cabinet 100 receives the test task from the remote automatic data platform M or manually input on site through the wireless communication module 2, it first controls the solenoid valve 4 to open and the other solenoid valves to close.

[0019] 2. The central control cabinet 100 sends a test command to the automatic liquid level tester 101 in the form of an electrical signal. The compressor 26 pressurizes the gas storage tank 29. When the pressure reaches the set value, the compressed gas is quickly released into the main pipeline 22 through the gas outlet pipeline 23, and then enters the oil well 10 through the branch pipeline 16.

[0020] 3. The compressed gas propagates downhole through the annulus of the casing and casing. When it encounters the dynamic fluid surface of the well, it generates a reflected pulse wave. The pulse wave returns to the automatic fluid level tester 101 through the annulus of the casing and casing of the well 10, the branch pipeline 16, and the main pipeline 22. The microphone 24 converts the pulse signal into an electrical signal, which is then digitally processed by the test controller 25.

[0021] 4. The processed digital signal is transmitted back to the central control cabinet 100 via the first connection line S. After being processed by the PLC controller 3, it is displayed on the touch screen 1. At the same time, it is transmitted back to the remote automatic data platform M via the wireless communication module 2, so as to realize the real-time update and viewing of data.

[0022] This automatic monitoring device for measuring the dynamic fluid level of multiple oil wells improves the efficiency of dynamic fluid level testing, reduces the labor intensity of employees and the cost of equipment such as automatic fluid level gauges, and enables one automatic fluid level gauge to monitor the dynamic fluid level of multiple wells on a large platform. This effectively improves the efficiency of on-site fluid level monitoring, reduces oxidation and corrosion of downhole casing, realizes remote dynamic fluid level monitoring of multiple oil wells, reduces the risk of hydrogen sulfide leakage, and improves work efficiency and economic benefits.

[0023] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
