Description

Technical Field

[0001] This application relates to the field of fluid processing technology, specifically to a fluid debris capture and control method and system. Background Technology

[0002] In the oil and gas extraction field, the fluid transport links between the high-pressure manifold and the wellhead in the surface process are the core link to ensure the continuous and efficient operation of gas extraction. During the extraction and transport of oil and gas fluids, solid impurities such as debris, rock cuttings, and perforation residue are inevitably introduced. If these impurities directly enter the subsequent high-pressure manifold system, they can easily cause pipeline blockage, wear on gate valve sealing surfaces, and increased equipment failure rates. In severe cases, they can even lead to the interruption of gas extraction operations, significantly increasing on-site maintenance costs and safety management pressures. Therefore, efficient solid impurity capture and solid-liquid separation of the fluid output from the wellhead is a key technical requirement for ensuring the stable operation of the surface process in oil and gas extraction.

[0003] Crucially, fluids in oil and gas extraction operations are often characterized by high pressure. During the switching between the cuttings collection channel and the main fluid channel, the opening and closing sequence of the gate valves directly affects the fluid pressure stability. If the gate valves open and close synchronously, the high-pressure fluid is prone to instantaneous pressure fluctuations and backflow, which not only severely impacts the gate valve sealing structure and accelerates valve body wear, but may also cause pipeline vibration, loosening of connections, and other safety hazards, posing a serious threat to the long-term stable operation of the equipment. Therefore, designing a reasonable gate valve opening and closing sequence to buffer high-pressure fluid impacts and prevent fluid backflow is a core technical point for improving the reliability of cuttings collection control devices.

[0004] Currently, there are still technical bottlenecks in the industry for the capture of solid impurities and channel switching control of high-pressure fluids that urgently need to be overcome. How to design a scientific gate valve start-stop sequence control logic to effectively buffer the impact of high-pressure fluids, avoid pressure fluctuations and fluid backflow risks, and adapt to the needs of remote automated control, while achieving efficient debris capture and ensuring solid-liquid separation, has become a core technical problem that must be solved to promote the upgrading of surface process equipment for oil and gas extraction and achieve safe and efficient operation.

[0014] Secondly, this application provides a fluid chip collection control system applied to an electric chip collection control device. The device includes multiple fluid channels connected in series, each fluid channel including a first electric gate valve. At least one of the fluid channels is connected in parallel to a chip collection channel, each chip collection channel including multiple second electric gate valves connected in series, with a chip collection cylinder disposed between the multiple second electric gate valves. The system includes: a data processing module configured to acquire process instructions and invoke corresponding fluid control strategies; a fluid control module communicatively connected to the data processing module, configured to control the opening and closing states of the fluid channels and the chip collection channel according to the fluid control strategy; and a monitoring module communicatively connected to the fluid control module, configured to detect when a fluid channel switches from an open state to a closed state. The system controls the first electric gate valve in the fluid channel to close, and controls all second electric gate valves in other chip collection channels (excluding the chip collection channel connected in parallel with the fluid channel) to close, and starts timing; if the chip collection channel is in operation, the system obtains the blockage status of the corresponding chip collection cylinder; if the chip collection cylinder is in a blocked state, the system sends an early warning signal; the fluid control module is also configured to: if the timing accumulates to a first preset duration, control all second electric gate valves in the chip collection channels connected in parallel with the fluid channel that has switched to the closed state to open sequentially at a first preset interval, and control all first electric gate valves in other fluid channels to open sequentially at a first preset interval; if a switching signal is obtained, the system closes the chip collection channel corresponding to the blocked chip collection cylinder and opens the fluid channel connected in parallel with the chip collection channel.

[0015] In conjunction with the second aspect, in one possible implementation, the data processing module includes: a mobile terminal, a wireless communication transmitter, a smart gateway, a switch, and a processor, all electrically connected to each other; the monitoring module includes: multiple pressure transmitters, with at least one pressure transmitter mounted on a first electric gate valve, at least one pressure transmitter mounted on a second electric gate valve, and pressure transmitters mounted at the second flanges at both ends of the chip collector; a first communicator, communicatively connected to each of the pressure transmitters; a second communicator, electrically connected to each of the first and second electric gate valves respectively; and a bus, electrically connected to the processor, the first communicator, and the second communicator respectively; the fluid control module includes: an electrical control cabinet, electrically connected to each of the first and second electric gate valves respectively, and the electrical control cabinet also communicatively connected to the processor.

If the chip collector becomes blocked, the chip collection channel containing the chip collector is automatically closed, and the fluid channel connected in parallel with the chip collection channel is automatically opened, thus allowing fluid to continue to be transported. After confirming that the electric gate valve is closed, it indicates that the first and second electric gate valves that need to be closed are indeed in the closed state. Using the closed feedback signal as a timing reference point, the timing is accumulated to a first preset time. Then, all the second electric gate valves in the chip collection channel corresponding to the closed fluid channel and all the first electric gate valves in the opened fluid channel are opened sequentially along the fluid transport direction. The first preset time interval allows the pressure of each device to reach a stable state. After the pressure stabilizes, the gate valves are opened to avoid pressure instability causing impact damage to the devices. The sequential opening action can prevent fluid backflow in the reverse direction of the transport direction. After the gate valves that need to be opened are opened sequentially, the high-pressure fluid enters the chip collection electric control device to perform the chip collection work. This system enables remote, automated control of the opening and closing strategies of the fluid and chip collection channels. During execution, a timer starts based on switching to the closed state. Once the timer meets the condition, the electric gate valves in the chip collection and fluid channels that need to be opened are opened sequentially. This ensures more stable, linear, and controllable flow of the high-pressure fluid, reducing the risk of valve body wear. The overall process effectively suppresses instantaneous pressure fluctuations and backflow of the high-pressure fluid, preventing strong impacts on the gate valve sealing structure, reducing safety hazards such as valve body wear, pipeline vibration, and loose connections, and effectively improving the long-term stability and reliability of the equipment.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all 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 scope of protection of this application.

[0029] An exemplary fluid debris trapping control method is as follows:

[0030] Figure 1 The diagram shown is a schematic representation of the steps of a fluid debris trapping control method provided in an embodiment of this application. Figure 2 The diagram shown is a structural schematic of a chip-collecting electric control device according to an embodiment of this application. This application provides a fluid chip-collecting control method, applied to a chip-collecting electric control device, as described above. Figure 2The chip-collecting electric control device includes multiple fluid channels connected in series. Each fluid channel includes a first electric gate valve 102. At least one fluid channel is connected in parallel with a chip-collecting channel, which includes multiple second electric gate valves 301 connected in series. A chip-collecting cylinder 302 is provided between the multiple second electric gate valves. The chip-collecting electric control device is installed between the surface process high-pressure manifold and the gas wellhead. The inlet of the first fluid channel along the conveying direction is connected to the underground pipeline of the gas well, and the outlet of the last fluid channel along the conveying direction is connected to the surface process high-pressure manifold. In one embodiment, as... Figure 1 As shown, the fluid debris trapping control method includes:

[0031] Step 110: Obtain process instructions and invoke the corresponding fluid control strategy.

[0032] In this step, process commands can be issued remotely via a mobile phone or remote control cabinet to control the chip-collecting electric control device to adjust to the process flow required for the current production. Different process commands correspond to different fluid control strategies, and the correspondence between process commands and fluid control strategies is preset.

[0033] Step 120: Control the opening and closing states of the fluid channel and the debris collection channel according to the fluid control strategy.

[0034] In this step, different fluid control strategies correspond to whether a certain fluid channel is open or closed, and whether a certain debris collection channel is open or closed.

[0035] Step 130: If a fluid channel switches from the open state to the closed state, the first electric gate valve 102 in the fluid channel is controlled to close, and all the second electric gate valves 301 in other chip collection channels other than the chip collection channel connected in parallel with the fluid channel are controlled to close, and the timing is started.

[0036] In this step, when fluid passes through the chip collection channel, the second electric gate valve 301 in the chip collection channel and various sensors in the chip collection cylinder 302 can detect the fluid passing through, indicating that the chip collection cylinder 302 is in operation and filters the fluid. The built-in filter cartridge of the chip collection cylinder 302 intercepts solid materials such as debris, rock chips, and perforation residue mixed in the fluid. The fluid, after being filtered by the filter cartridge, flows out through the filter holes. Solid materials are blocked inside the chip collection cylinder 302 by the filter cartridge, thus achieving solid-fluid separation and preventing large amounts of solid materials from entering subsequent processes. This effectively prevents blockage of subsequent channels and excessive wear of the electric gate valve.

[0037] Step 140: If the timer accumulates to the first preset duration, then along the fluid transport direction, control all the second electric gate valves 301 in the parallel chip collection channel of the fluid channel that has been switched to the closed state to open sequentially at the first preset interval duration, and control all the first electric gate valves 102 in other fluid channels to open sequentially at the first preset interval duration.

[0038] In steps 130 and 140, when a fluid channel is switched to the closed state, the chip-collecting channel connected in parallel with it is switched to the open state, while other fluid channels connected in series with it are switched to the open state, and the chip-collecting channels connected in parallel with the fluid channels that are switched to the open state are switched to the closed state. When a closed feedback signal is confirmed, it indicates that the first electric gate valve 102 and the second electric gate valve 301 that need to be switched to the closed state are indeed in the closed state. Then, the timer is accumulated to a first preset time, and then all the second electric gate valves 301 in the chip-collecting channels that are switched to the open state and all the first electric gate valves 102 in the fluid channels that are switched to the open state are opened sequentially along the fluid conveying direction. The interval of the first preset time allows the pressure of each device to reach a stable state before the gate valves are opened, which can effectively avoid damage to the devices caused by pressure instability; the sequential opening action can prevent the fluid from flowing back in the opposite direction of the conveying direction; after the gate valves that need to be opened are opened sequentially, the high-pressure fluid enters the chip-collecting electric control device to perform the chip-collecting work.

[0039] Step 150: If the chip collection channel is in operation, obtain the blockage status of the corresponding chip collection cylinder.

[0040] In steps 140 and 150, when the chip collection channel is put into operation, the pressure difference between the two ends of the chip collection cylinder 302 can be known through the pressure transmitters installed at both ends of the chip collection cylinder 302 in the chip collection channel. If the pressure difference is greater than the preset pressure difference, it can be determined that the chip collection cylinder 302 is in a blocked condition.

[0041] Step 160: If the chip collector is blocked, a warning signal will be sent.

[0042] Step 170: If a switching signal is received, close the chip collection channel corresponding to the chip collection cylinder in the blockage condition, and open the fluid channel connected in parallel with the chip collection channel.

[0043] In step 170, after closing the blocked chip collection channel, the fluid channel connected in parallel with it is opened, allowing the fluid to enter the next process for transportation.

[0044] In this embodiment, the operating status of the chip collector 302 can be automatically acquired. If the chip collector 302 becomes blocked, the chip collection channel containing the chip collector 302 is automatically closed, and the fluid channel connected in parallel with the chip collection channel is automatically opened, so that fluid can continue to be transported. After confirming that the electric gate valve is closed, it indicates that the first electric gate valve 102 and the second electric gate valve 301 that need to be closed are indeed in the closed state. Using the obtained feedback signal as a timing reference point, the timing is accumulated to a first preset time, and then all the second electric gate valves 301 in the chip collection channel corresponding to the fluid channel switched to the closed state and all the first electric gate valves 102 in the fluid channel switched to the open state are opened sequentially along the fluid transport direction. The first preset time interval allows the pressure of each device to reach a stable state before the gate valve opening operation is performed to avoid pressure instability causing impact damage to the devices; the sequential opening operation can prevent the fluid from flowing back in the opposite direction of the transport direction. After the gate valves that need to be opened are opened sequentially, the high-pressure fluid enters the chip collection electric control device to perform the chip collection operation. In this embodiment, the opening and closing strategies of the fluid channel and the chip collection channel can be remotely and automatically controlled. During the execution of the opening and closing strategy, a timer is started based on switching to the closed state. After the timer meets the condition, the electric gate valves in the chip collection channel and the fluid channel that need to be opened are opened sequentially. This makes the flow of high-pressure fluid more stable, linear, and controllable, reducing the risk of valve body wear. The overall process can effectively suppress instantaneous pressure fluctuations and backflow of high-pressure fluid, avoid strong impacts on the gate valve sealing structure, reduce safety hazards such as valve body wear, pipeline vibration, and loosening of connecting parts, and effectively improve the long-term stability and reliability of the equipment.

[0045] Reference Figure 2 The device includes a first fluid channel 1 and a second fluid channel 2 connected in series. A first chip-collecting channel 3 is connected in parallel to two first flanges 101 at the ends of the first fluid channel 1, and a second chip-collecting channel 4 is connected in parallel to two first flanges 101 at the ends of the second fluid channel 2. Figure 2 The first fluid channel 1, the second fluid channel 2, the first debris-collecting channel 3, and the second debris-collecting channel 4 are circled with dashed lines.

[0046] Specifically, the first fluid channel 1 has first flanges 101 at both ends, one of which is connected to an underground fluid delivery pipe, and the other is connected to a first flange 101 at the end of the second fluid channel 2. A first electric gate valve 102 is connected in series between the first flanges 101 at both ends of the first fluid channel 1, and a first electric gate valve 102 is also connected in series between the first flanges 101 at both ends of the second fluid channel 2. The first chip-collecting channel 3 includes a second electric gate valve 301, a chip-collecting cylinder 302, and another second electric gate valve 301 connected in series. The second electric gate valves 301 at both ends of the first chip-collecting channel 3 are connected to the first flanges 101 at both ends of the first fluid channel 1. The second chip-collecting channel 4 includes a second electric gate valve 301, a chip-collecting cylinder 302, and another second electric gate valve 301 connected in series. The second electric gate valves 301 at both ends of the second chip-collecting channel 4 are connected to the first flanges 101 at both ends of the second fluid channel 2. High-pressure fluid in the well enters from the first flange 101 below the first fluid channel 1 and exits from the first flange 101 above the second fluid channel 2.

[0047] Figure 3 The diagram illustrates the specific steps of the first strategy. In one embodiment, as shown... Figure 3 As shown, step 110 includes:

[0048] Step 111: If the first process instruction is obtained, the corresponding first strategy is invoked.

[0049] Step 120 includes:

[0050] Step 121: According to the first strategy, control the first fluid channel 1 to close, the first debris-collecting channel 3 to open, the second fluid channel 2 to open, and the second debris-collecting channel 4 to close, or control the first fluid channel 1 to open, the first debris-collecting channel 3 to close, the second fluid channel 2 to close, and the second debris-collecting channel 4 to open.

[0051] In this embodiment, the fluid passes through the first debris-collecting channel 3 and the second fluid channel 2 in sequence, or the fluid passes through the first fluid channel 1 and the second debris-collecting channel 4 in sequence.

[0052] Figure 4 The diagram shows one execution flow step under the first strategy. Based on step 121, as follows... Figure 4 As shown, step 120 includes:

[0053] Step 1211: According to the first strategy, control the first fluid channel 1 to close, the first debris-collecting channel 3 to open, the second fluid channel 2 to open, and the second debris-collecting channel 4 to close.

[0054] Step 130 includes:

[0055] Step 1311: Control the first electric gate valve 102 in the first fluid channel 1 to close, and control all the second electric gate valves 301 in the second chip collection channel 4 to close; if feedback signals indicating that the first electric gate valve 102 and the second electric gate valve 301 are closed are obtained, then start timing.

[0056] Step 140 includes:

[0057] Step 1411: If the timer accumulates to the first preset duration, then along the fluid transport direction, control all the second electric gate valves 301 in the first chip collection channel 3 to open sequentially at the first preset interval duration, and control the first electric gate valves 102 in the second fluid channel 2 to open sequentially at the first preset interval duration.

[0058] The fluid debris control method also includes:

[0059] Step 1500: If feedback signals indicating that the second electric gate valve 301 and the first electric gate valve 102 are in the open position are obtained, then the control fluid enters the chip collection electric control device.

[0060] In this embodiment, after step 1211, confirming the acquisition of the closed-in feedback signal indicates that the first electric gate valve 102 and the second electric gate valve 301, which need to be closed, are indeed in the closed state. Then, the timing is accumulated to a first preset time, and the gate valves in the first chip-collecting channel 3 and the second fluid channel 2 are opened sequentially. The first preset time interval allows the pressure of each device to reach a stable state. After the pressure stabilizes, the gate valves are opened to avoid damage to the devices due to pressure instability. The sequential opening action can prevent fluid backflow in the opposite direction of the conveying direction. After opening the gate valves that need to be opened sequentially, the first flange 101 at the end of the first fluid channel 1 is opened to allow high-pressure fluid to enter the chip-collecting electric control device and perform chip-collecting work through the first chip-collecting channel 3.

[0061] Figure 5 The diagram shows another execution flow step under the first strategy. Based on step 121, as follows... Figure 5 As shown, step 120 includes:

[0065] Step 140 includes:

[0066] Step 1412: If the timer accumulates to the second preset duration, then along the fluid transport direction, control the first electric gate valve 102 in the first fluid channel 1 to open sequentially at the second preset interval duration, and control all the second electric gate valves 301 in the second debris collection channel 4 to open sequentially at the second preset interval duration.

[0067] The fluid debris control method also includes:

[0068] Step 1501: If feedback signals indicating that the first electric gate valve 102 and the second electric gate valve 301 are in the open position are obtained, then the control fluid enters the chip collection electric control device.

[0069] In this embodiment, after step 1221, confirming the acquisition of the closed feedback signal indicates that the first electric gate valve 102 and the second electric gate valve 301, which need to be closed, are indeed in the closed state. Then, the timing is accumulated to a second preset time, and the gate valves in the first fluid channel 1 and the second chip-collecting channel 4 are opened sequentially. The second preset time interval allows the pressure of each device to reach a stable state. After the pressure stabilizes, the gate valves are opened to avoid damage to the devices caused by pressure instability. The sequential opening action can prevent the fluid from flowing back in the opposite direction of the conveying direction. After opening the gate valves that need to be opened sequentially, the first flange 101 at the end of the first fluid channel 1 is opened to allow the high-pressure fluid to enter the chip-collecting electric control device and perform chip-collecting work through the second chip-collecting channel 4.

[0070] The above process flow uses at least one chip collector 302 for fluid chip collection. The specific process to be executed can be directly set via a remote control cabinet and / or a mobile device. Alternatively, if one chip collector 302 becomes clogged, a switching operation can be performed to switch the chip collection operation to another chip collection channel. The first and second preset durations are generally set to any value between 2 and 5 seconds, and the first and second preset interval durations are generally set to any value between 1 and 4 seconds.

[0071] Figure 6 The diagram illustrates the specific steps of the second strategy. In one embodiment, referring to... Figure 2The device includes a first fluid channel 1 and a second fluid channel 2 connected in series. A first debris-collecting channel 3 is connected in parallel to a first flange 101 located at both ends of the first fluid channel 1, and a second debris-collecting channel 4 is connected in parallel to a first flange 101 located at both ends of the second fluid channel 2. Figure 6 As shown, step 110 includes:

[0072] Step 112: If the second process instruction is obtained, the corresponding second strategy is invoked.

[0073] Step 120 includes:

[0074] Step 122: According to the second strategy, control the first fluid channel 1 to open, the first debris-collecting channel 3 to close, the second fluid channel 2 to open, and the second debris-collecting channel 4 to close.

[0075] In this step, the fluid passes through the first fluid channel 1 and the second fluid channel 2 in sequence, which can be applied to the transportation of fluids with fewer impurities and can improve the fluid throughput efficiency.

[0076] In some embodiments, three options are pre-set on the remote control cabinet and / or mobile terminal, corresponding to: Type A production process: control the first fluid channel 1 to be closed, the first chip collection channel 3 to be open, the second fluid channel 2 to be open, and the second chip collection channel 4 to be closed; Type B production process: control the first fluid channel 1 to be open, the first chip collection channel 3 to be closed, the second fluid channel 2 to be closed, and the second chip collection channel 4 to be open; Type C production process: control the first fluid channel 1 to be open, the first chip collection channel 3 to be closed, the second fluid channel 2 to be open, and the second chip collection channel 4 to be closed.

[0077] Figure 7 The diagram illustrates the steps of a pressure relief process. In one embodiment, refer to... Figure 2 Two pressure relief electric cocks 304 are respectively installed at the second flanges 303 at both ends of the chip collector 302. Figure 7 As shown, after steps 150 and 160, the method further includes:

[0078] Step 190: Determine whether a pressure relief command has been received. If so, proceed to step 200: Start the pressure relief process.

[0079] When a chip collector 302 is clogged and needs to be cleaned or its filter element replaced, the chip collector 302 should be depressurized.

[0080] After step 200, proceed to either step 210 or step 220.

[0081] Step 210: Control the pressure relief electric cock 304 to open at the preset ratio.

[0082] In this step, the pressure inside the chip collector 302 is released slowly according to a preset proportional opening to avoid damaging the chip collector 302 due to excessively rapid pressure release. The preset proportional opening can be set on a remote control cabinet or a remote mobile terminal.

[0083] Step 220: Control the pressure relief electric cock 304 to open at a gradually increasing ratio.

[0084] In this step, the pressure inside the chip collector 302 is released slowly with a gradually increasing proportional opening. This allows for a smaller opening during the initial high-pressure period, followed by a gradual increase in the proportional opening after a certain pressure has been released, thus preventing damage to the chip collector 302 due to excessively rapid pressure release. The increase in the proportional opening can be set on a remote control cabinet or a remote mobile device.

[0085] Step 230: Determine whether the chip collector 302 has been depressurized to the preset pressure. If so, proceed to step 240.

[0086] Step 240: Send a pressure relief completion signal.

[0087] This embodiment can automatically depressurize the chip collector 302, and the depressurization process will not cause damage to the chip collector 302 due to excessively rapid pressure release.

[0088] Figure 8 The diagram shown illustrates the maintenance process. In one embodiment, as... Figure 8 As shown, the fluid debris trapping control method further includes:

[0089] Step 240: Determine if a pressure relief completion signal has been obtained. If so, proceed to step 250: Generate a maintenance signal. The maintenance signal can be used to indicate that the pressure relief of the chip collector 302 has been completed, and the chip collector 302 can be cleaned or the filter element of the chip collector 302 can be replaced. The chip collector 302 can be cleaned and maintained by opening the filter element removal port 3021.

[0090] Step 260: Determine whether a maintenance completion signal has been obtained. If so, proceed to step 270.

[0091] Step 270: Generate a standby command for the corresponding chip collector. The standby command can be used to indicate that the maintained chip collector 302 can be put into chip collection work.

[0092] Figure 9 The diagram illustrates the specific steps of remote control. In one embodiment, as shown... Figure 9 As shown, the fluid debris trapping control method further includes:

[0093] Step 300: Collect the operating condition data of the first electric gate valve, the second electric gate valve, and the chip collector, and send the operating condition data to the remote control cabinet and / or mobile terminal.

[0094] Step 310: Obtain process instructions sent by the remote control cabinet and / or mobile terminal.

[0095] This embodiment can further realize remote monitoring and control. The remote control cabinet and / or mobile terminal can remotely view the operating data, and process instructions can be issued by the remote control cabinet and / or mobile terminal.
