Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for oil drilling, and in particular to a well control fluid level control and injection device. Background Technology

[0002] Well control fluid level control and injection devices are commonly used in the safety management of oil and gas wells, especially during drilling operations. They are important equipment to ensure stable wellhead pressure and prevent accidents such as blowouts. However, the injection devices on the market do not have a quantitative setting when injecting drilling fluid, which will make it impossible to guarantee the injection volume of drilling fluid.

[0003] To address the aforementioned issues, existing patents provide a drilling fluid injection device with precise quantitative function (publication number: CN213360060U). This patent utilizes an infrared distance sensor, a control terminal, and a solenoid valve. By combining the injection time with a pre-controlled time, the infrared distance sensor calculates the drilling fluid level when it is about to be filled and feeds it back to the control terminal. Subsequently, the control terminal activates the solenoid valve to close the drilling fluid delivery channel, thereby completing the precise quantitative injection of drilling fluid and effectively preventing overflow caused by full filling.

[0004] However, in actual use, the above technical solutions are subject to significant vibrations during construction. The accuracy of infrared detection is low, and if the position of the infrared distance sensor shifts due to vibration, causing the infrared beam to tilt, it can easily lead to abnormal injection of drilling fluid, affecting construction. At the same time, due to the lack of an indicator mechanism, it is difficult to observe and alarm on changes in the fluid level at the wellhead in a timely manner, that is, it is impossible to react and judge the fluid level situation in the well quickly. In order to address the above technical defects, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a well control liquid level control and injection device to solve the technical defects mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: A well-controlled liquid level control and injection device includes a vertical pipe, a top cover fixedly installed on the top of the vertical pipe, an infrared distance sensor fixedly installed on the top cover, an injection pipe fixedly installed on one side of the vertical pipe, and a control component fixedly installed inside the vertical pipe; the control component includes an airbag one, an airbag two, a moving block one, and a contact block, the airbag one is fixedly installed inside the vertical pipe, the airbag two is fixedly installed on the outer wall of the vertical pipe, the moving block one is fixedly installed on the top of the airbag two, the contact block is located above the moving block one, and the airbag one is fixedly connected to the airbag two through a pipeline; the control component also includes an airbag three, an airbag four, the moving block two, and a buzzer, the airbag three is fixedly installed inside the vertical pipe and is located above the airbag one, the airbag four is fixedly installed on the top cover and is fixedly connected to the airbag three through a pipeline, the moving block two is fixedly installed on the top of the airbag four, and the buzzer is located above the moving block two.

[0012] The beneficial effects of this utility model are as follows: (1) This utility model uses the cooperation of components such as airbag one, airbag two and moving block one. In the initial state, airbag one is compressed under the action of the liquid surface. Under the action of airbag two, moving block one and contact block are against each other. When the liquid level drops, airbag one gradually expands. Gas enters airbag one from airbag two. Airbag two gradually contracts. Moving block one and contact block gradually separate. After moving block one and contact block separate, drilling fluid is delivered to the vertical pipe through the injection pipe. As the liquid level rises, airbag two gradually expands until moving block one and contact block are against each other again. At this time, the injection ends. During the process, the liquid level is continuously monitored by an infrared distance sensor. (1) The surface is inspected. Through the linkage of the moving block 1, the contact block and the infrared distance sensor, the accuracy of liquid level detection is effectively improved and normal construction is guaranteed. (2) This utility model uses the combination of components such as airbag 3, airbag 4 and moving block 2. In the initial state, airbag 3 is in an expanded state and moving block 2 does not contact the buzzer. When an abnormality occurs and the liquid level continues to rise, airbag 3 is gradually squeezed and gas enters airbag 4 from airbag 3. Moving block 2 gradually moves up under the action of airbag 4. When moving block 2 contacts the buzzer, the buzzer starts and a sharp alarm is triggered to remind the staff and realize a rapid response and judgment of the liquid level in the well.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: This example addresses the issue of significant vibrations occurring during construction, where infrared detection is inaccurate. Furthermore, if the infrared distance sensor shifts due to vibration, causing the infrared beam to tilt, it can easily lead to abnormal injection of drilling fluid, thus affecting the construction process.

[0022] Please see Figure 1 - Figure 3 As shown, this embodiment is a well control fluid level control and injection device, including a vertical pipe 1, a top cover 101 fixedly installed on the top of the vertical pipe 1, an infrared distance sensor fixedly installed on the top cover 101, an injection pipe 102 fixedly installed on one side of the vertical pipe 1, and a control component 2 fixedly installed inside the vertical pipe 1.

[0023] The control component 2 includes an airbag 201, an airbag 202, a moving block 203, and a contact block 204. The airbag 201 is fixedly installed inside the vertical tube 1, the airbag 202 is fixedly installed on the outer wall of the vertical tube 1, the moving block 203 is fixedly installed on the top of the airbag 202, and the contact block 204 is located above the moving block 203. A Bluetooth transmission module is fixedly installed inside the contact block 204. When the moving block 203 and the contact block 204 are separated, the Bluetooth module sends a signal to the control system, which then controls the motor to work.

[0024] Fixed pipe 1 208 and fixed pipe 209 are fixedly installed in vertical pipe 1. Airbag 1 201 is fixedly installed in fixed pipe 1 208, and airbag 3 205 is fixedly installed in fixed pipe 2 209. Movable rods 210 are movably installed in both fixed pipe 1 208 and fixed pipe 2 209. A float plate 211 is fixedly installed at the bottom of the movable rod 210. Springs are fixedly installed in both airbag 1 201 and airbag 3 205 for resetting airbag 1 201 and airbag 2 202. When the liquid surface contacts the float plate 211, the buoyancy drives the movable rod 210 to move upward, squeezing airbag 1 201, thereby allowing gas to enter airbag 2 202.

[0025] Similarly, when the liquid level continues to rise and comes into contact with the float plate 211 in the fixed tube 209, the moving rod 210 moves upward to squeeze the airbag 3 205, and the gas in the airbag 3 205 enters the airbag 4 206.

[0026] In the initial state, airbag 1 201 is compressed under the action of the liquid surface. Under the action of airbag 2 202, moving block 1 203 and contact block 204 abut against each other. When the liquid level drops, airbag 1 201 gradually expands, and gas enters airbag 1 201 from airbag 2 202. Airbag 2 202 gradually contracts, and moving block 1 203 and contact block 204 gradually separate. After moving block 1 203 and contact block 204 separate, drilling fluid is delivered to the vertical pipe 1 through injection pipe 102. As the liquid level rises, airbag 2 202 gradually expands until moving block 1 203 and contact block 204 abut against each other again, at which point the injection ends. During the above process, the liquid level is continuously detected by an infrared distance sensor. Through the linkage and cooperation of moving block 1 203, contact block 204 and infrared distance sensor, the accuracy of liquid level detection is effectively improved, ensuring normal construction.

[0027] Example 2: This example is used to solve the problem that changes in the wellhead fluid level are difficult to observe and alarm in a timely manner due to the lack of an indicator mechanism, that is, the fluid level situation in the well cannot be quickly reacted to and judged.

[0028] Please see Figure 4 - Figure 5 As shown, this utility model also includes airbag three 205, airbag four 206, moving block two 207 and buzzer. Airbag three 205 is fixedly installed inside the vertical tube 1 and is located above airbag one 201. Airbag four 206 is fixedly installed on the top cover 101. Moving block two 207 is fixedly installed on the top of airbag four 206 and buzzer is located above moving block two 207.

[0029] A fixed pipe 3 212 is fixedly installed on the outer wall of the vertical pipe 1. An airbag 2 202 is fixedly installed in the fixed pipe 3 212. A movable block 1 203 is movably installed in the fixed pipe 3 212. A contact block 204 is fixedly installed on the top of the fixed pipe 3 212. A fixed pipe 4 213 is fixedly installed on the top of the top cover 101. An airbag 4 206 is fixedly installed in the fixed pipe 4 213. A movable block 2 207 is movably installed in the fixed pipe 4 213. A buzzer is fixedly installed on the top of the fixed pipe 4 213. The buzzer has a built-in power supply and does not require an external power supply. The buzzer switch is located at the bottom. When the movable block 2 207 touches the bottom of the buzzer, the buzzer is activated and an alarm is sounded.

[0030] An inlet pipe 103 is fixedly installed at the top of the injection pipe 102. A rotating rod 104 is movably installed inside the injection pipe 102. A spiral fan blade is fixedly installed on the rotating rod 104. A motor is fixedly installed at one end of the injection pipe 102. The output end of the motor is fixedly connected to the rotating rod 104. Drilling fluid is transported to the injection pipe 102 through the inlet pipe 103. When injecting fluid into the riser pipe 1, the motor is started to drive the rotating rod 104 to rotate. The spiral fan blade is used to push the drilling fluid into the riser pipe 1. That is, the injection speed is controlled by controlling the speed of the rotating rod 104, and quantitative injection is achieved at the same time.

[0031] In the initial state, airbag 3 205 is inflated, and moving block 2 207 is not in contact with the buzzer. When an abnormality occurs and the liquid level continues to rise, airbag 3 205 is gradually compressed, and gas enters airbag 4 206 from airbag 3 205. Moving block 2 207 gradually moves upward under the action of airbag 4 206. When moving block 2 207 comes into contact with the buzzer, the buzzer is activated and a sharp alarm is sounded to remind the staff and enable a rapid response and judgment of the liquid level in the well.

[0032] Combining Embodiments 1 and 2, the injection process is controlled through the coordinated operation of components such as movable block 203 and contact block 204. During the process, the liquid level is continuously detected by an infrared distance sensor. That is, the coordinated operation of movable block 203, contact block 204 and infrared distance sensor effectively improves the accuracy of liquid level detection and ensures normal construction. At the same time, through the coordinated operation of movable block 207 and buzzer, the buzzer will sound an alarm in time when the liquid level is abnormal, thereby reminding the staff and realizing rapid response and judgment of the liquid level in the well.

[0033] The working process and principle of this utility model are as follows: First, the injection process is controlled by the linkage of components such as moving block 203 and contact block 204. During the process, the liquid level is continuously detected by an infrared distance sensor. That is, the linkage of moving block 203, contact block 204 and infrared distance sensor effectively improves the accuracy of liquid level detection and ensures normal construction. Furthermore, the linkage of moving block 207 and buzzer and other components enables the buzzer to sound an alarm in time when an abnormality occurs in the liquid level, thereby reminding the staff and realizing a rapid response and judgment of the liquid level situation in the well. That is, this utility model, through the set control component 2, not only effectively improves the accuracy of liquid level detection, but also realizes a rapid response and judgment of the liquid level situation in the well.
