Description

Technical Field

[0001] The invention relates to the field of oil production and fracturing equipment, in particular to an anti-lateral shift automatic monitoring and alarm system. Background Art

[0002] Currently, the fracturing reservoirs commonly used at domestic fracturing sites are primarily composed of several components, including the inlet crane, reservoir, and manifold. To meet the demands of fracturing operations, the reservoirs must be filled with water, typically holding 2,000 to 4,000 cubic meters of water. Due to the large volume of water, the tanks are subject to significant pressure. While some protective measures currently in place can provide some support for the reservoirs, these measures are limited and cannot effectively mitigate risks. If lateral shifting of the reservoir is not discovered in time, it can pose a serious safety hazard to the entire fracturing site and even result in significant economic losses. Currently, manual inspections are the primary method used to check for any anomalies in the tanks. However, visual inspections of the tanks to determine lateral shifting are prone to errors and omissions, increasing labor costs and reducing work efficiency. Summary of the Invention

In the detailed description of the present invention below, some specific details are described in detail. However, for the part that is not described in detail, those skilled in the art can also fully understand the present invention.

[0032] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and are not actually drawn to scale.

[0033] At the same time, unless the context clearly requires otherwise, words such as "include", "comprising" and the like throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, as "including but not limited to".

[0034] Figure 1 This is a schematic diagram of the structure of an automatic monitoring and alarm system for preventing lateral movement according to an embodiment of the present invention. Figure 1As shown, an automatic monitoring and alarm system for preventing lateral displacement includes: a supporting mechanism, a detecting mechanism, a straightening mechanism, a control unit and an alarm unit 2; the supporting mechanism is connected to the detecting mechanism via the straightening mechanism, one side of the supporting mechanism is connected to the object to be detected, and the bottom is fixed on the ground; the supporting mechanism is used to squeeze the supporting mechanism when the object to be detected shifts sideways, and the supporting mechanism applies pressure to the detecting mechanism, and the detecting mechanism is used to detect the real-time pressure value of the pressure applied by the supporting mechanism; the detecting mechanism is connected to the control unit, and the detecting mechanism transmits the detected real-time pressure value to the control unit, and the control unit is connected to the alarm unit 2; the control unit is used to determine whether the pressure value is greater than a predetermined pressure value, and if so, the controller controls the alarm unit 2 to sound an alarm.

[0035] In an embodiment of the present invention, the object to be tested is a fracturing reservoir at an oil and gas field well site. During use, a support mechanism is fixed to the outer wall of the fracturing reservoir tank 1. When the outer wall of the fracturing reservoir expands and moves laterally outward, it compresses the support mechanism, which in turn compresses the detection mechanism, thereby applying pressure to the detection mechanism. The detection mechanism is connected to a control unit via a wireless transmission module. The detection mechanism detects the real-time pressure value of the pressure applied by the support mechanism and transmits it to the control unit via the wireless transmission module. The control unit determines whether this real-time pressure value exceeds a predetermined pressure value. If so, the controller controls the alarm unit 2 to issue an alarm. The predetermined pressure value is the maximum pressure that the tank 1 can withstand. Exceeding this pressure value indicates that the tank 1 has expanded and moved laterally too far, which may pose a danger. The controller can be a PLC controller. The controller can be connected to a fracturing field instrument vehicle. When the controller controls the alarm unit to sound an alarm, it also sends a signal to the instrument vehicle, which then sends a unified processing instruction, thereby improving the response speed of on-site personnel.

[0036] In the present invention, the support mechanism includes: a support frame; the support frame includes a first pressure rod 5, a second pressure rod 6, a first support rod 3 and a second support rod 4; one end of the first pressure rod 5 is connected to one end of the detection mechanism, and the other end of the first pressure rod 5 is connected to one end of the first support rod 3; one end of the second pressure rod 6 is connected to the other end of the detection mechanism, and the other end of the second pressure rod 6 is connected to one end of the second support rod 4; the other end of the second support rod 4 is axially connected to the other end of the first support rod 3; the side of the first support rod 3 away from the first pressure rod 5 is fixed to the side wall of the object to be tested; one side of the second support rod 4 is fixed to the ground, and in a natural state, the angle between the first support rod 3 and the second support rod 4 is a right angle.

[0037] In an embodiment of the present invention, the side of the first support rod 3 away from the first pressure rod 5 is connected to the side wall of the tank body 1. In a natural state, the first support rod 3 is perpendicular to the ground. The second support rod 4 is placed flat and fixed on the ground, and the other end of the second support rod 4 is axially connected to the other end of the first support rod 3. In a natural state, the connected first support rod 3, the second support rod 4, the first pressure rod 5, the second pressure rod 6 and the detection mechanism together form a right triangle. When the tank body 1 shifts sideways, usually the upper half begins to expand outward. When the upper half of the side wall of the tank body 1 shifts sideways, pressure will be applied to one end of the first support rod 3 in the direction away from the tank body 1. Since the other end of the first support rod 3 is axially connected to the other end of the second support rod 4 and cannot bear pressure, one end of the first support rod 3 will apply pressure in the direction of the first pressure rod 5. At the same time, because the second pressure rod 6 is fixedly connected to the second support rod 4 fixed to the ground, thereby supporting the detection mechanism, the first pressure rod 5 will apply pressure to the detection mechanism. The detection mechanism detects the real-time pressure value applied to it by the first support rod 3 and transmits it to the controller. The controller determines whether the real-time pressure value is greater than the predetermined pressure value. If it is greater, the controller controls the alarm unit 2 to activate the alarm.

[0038] Because the first pressure rod 5, the detection mechanism, and the second pressure rod 6 are fixed by the second support rod 4, while detecting whether the pressure in the tank body 1 is too high and prone to lateral movement, it can also provide a certain support for the tank body 1 to prevent the tank body 1 from tipping over. Multiple support mechanisms can be installed around the tank body 1 as needed to better play the supporting and detection roles.

[0039] In the present invention, the straightening mechanism includes: a first straightener 7 and a second straightener 8; one end of the first pressure rod 5 is connected to one end of the detection mechanism through the first straightener 7; one end of the second pressure rod 6 is connected to the other end of the detection mechanism through the second straightener 8; the straightening mechanism is used to keep the first pressure rod 5, the detection mechanism and the second pressure rod 6 in the same straight line.

[0040] In this embodiment of the present invention, the centralizing mechanism includes a first centralizer 7 and a second centralizer 8. The first and second centralizers 7 and 8 are rectangular parallelepiped bodies with a hollow interior and openings at both ends. One end of the first centralizer 7 is connected to one end of the detection mechanism, and one end of a first pressure rod 5 is inserted into the first centralizer 7 through the other end opening. The outer shape of the first pressure rod 5 matches the inner shape of the first centralizer 7. One end of the second centralizer 8 is connected to the other end of the detection mechanism, and one end of a second pressure rod 6 is inserted into the second centralizer 8 through the other end opening. The outer shape of the second pressure rod 6 matches the inner shape of the second centralizer 8. The ends of the first centralizer 7 and the second centralizer 8 are aligned. Because the first and second pressure rods 5 and 6 are inserted into the first and second centralizers 7 and 8, the first and second pressure rods 5 and 6 are kept aligned by the first and second centralizers 7 and 8. Thus, when the first support rod 3 applies pressure to the first pressure rod 5, it plays a straightening role, keeping the positions of the first pressure rod 5, the detection mechanism and the second pressure rod 6 unchanged, and preventing deformation that may cause inaccurate pressure detection by the detection mechanism or damage to the support mechanism.

[0041] In the present invention, the detection mechanism is: a pressure sensor 9; one end of the pressure sensor 9 is connected to one end of the first pressure rod 5, and the other end of the pressure sensor 9 is connected to one end of the second pressure rod 6; the pressure sensor 9 is connected to the controller through a wireless transmission module.

[0042] In this embodiment of the present invention, a pressure sensor 9 has a sensing head with one end connected to the first centralizer 7 and the first pressure rod 5, and the other end connected to the second pressure rod 6 via the second centralizer 8. Pressure sensor 9 is connected to the controller via a wireless transmission module. When the pressure inside the tank 1 rises and the sidewalls move outward, the first support rod 3 pushes against the first pressure rod 5, which in turn applies pressure to the pressure sensor 9. When the pressure sensor 9 detects the pressure applied by the first pressure rod 5, it transmits the real-time pressure value to the controller.

[0043] In the present invention, the alarm unit 2 includes: an alarm light and a buzzer; the alarm light and the buzzer are fixed on the object to be tested; the alarm light and the buzzer are respectively connected to the controller through a wireless transmission module, and the controller is used to control the start or stop of the alarm light and / or the buzzer.

[0044] In an embodiment of the present invention, an alarm light and a buzzer are installed on the tank body 1. When the controller determines that the real-time pressure value detected by the detection mechanism is greater than the predetermined pressure value, the controller controls the alarm light to light up and the buzzer to sound a buzzer alarm to remind on-site staff to take timely action.

[0045] In an embodiment of the present invention, when in use, the first support rod 3 is connected to the side wall of the tank body 1 away from the first pressure rod 5, and the second support rod 4 is fixed on the ground. When water is stored in the tank body 1, as the pressure in the tank body 1 increases, the outer wall of the tank body 1 expands and deforms outward to apply pressure to the first support rod 3. One end of the first support rod 3 will apply pressure in the direction of the first pressure rod 5. The first pressure rod 5 applies pressure to the pressure sensor 9. When the pressure sensor 9 detects the pressure applied by the first pressure rod 5, the detected real-time pressure value is transmitted to the controller. The controller determines that when the real-time pressure value is greater than the predetermined pressure value, that is, the tank body 1 can withstand the maximum pressure, the alarm light is controlled to light up and the buzzer is controlled to sound a buzzer alarm to remind on-site staff to deal with it in time.

[0046] The present invention has a simple structure, is easy to operate, and is safe and reliable in operation. The pressure on the tank body 1 is detected by the controller, i.e., the pressure sensor 9. This not only solves the problem that the deformation of the tank body 1 of the fracturing water reservoir cannot be discovered in time by the naked eye, but also meets the requirement of reducing the number of inspectors on the fracturing site. At the same time, safety is guaranteed, and the efficiency of the fracturing operation is greatly improved. It has good practical application value, and has been recognized from the overall design of the scheme to the on-site operation trial process, and can be promoted for use in various domestic oil and gas fields.

[0047] The above-described embodiments are merely embodiments of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications, equivalent substitutions, and improvements without departing from the scope of the present invention, and these modifications fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the appended claims.
