Description

Technical Field

[0001] This application relates to the field of oil and gas treatment technology, specifically to a wireless IoT control method and system for a cyclone sand separator. Background Technology

[0002] During oil and gas extraction, the high-pressure oil and gas fluid produced at the wellhead often carries sand and gravel, requiring solid-liquid separation using a hydrocyclone desander. Currently, the sand discharge and pressure relief operation of a single-cylinder hydrocyclone desander relies entirely on manual operation: operators need to conduct regular on-site inspections, observe the mechanical pressure gauges installed on the equipment to determine the inlet and outlet pressure data, and then manually adjust the gate valve opening of the sand discharge pipeline based on experience to control the sand discharge operation.

[0003] This traditional manual control method has many drawbacks: First, operators need to frequently travel between various well sites, resulting in high labor intensity and low efficiency in harsh environments such as deserts and Gobi. Second, relying entirely on manual judgment of pressure changes and valve operation leads to response lag, making it difficult to respond promptly to sudden pressure fluctuations. Third, data from mechanical pressure gauges cannot be transmitted remotely, preventing managers from monitoring equipment operating status in real time. Most importantly, in high-pressure oil and gas environments, manual operation poses significant safety risks; improper operation or delayed response can cause equipment blockage or even accidents. Therefore, developing a non-manually controlled desanding and pressure relief operation for cyclone desanders is a technical problem that needs to be solved in this field. Summary of the Invention

[0004] In view of this, this application provides a wireless IoT control method and system for a hydrocyclone sand separator, which can remotely and automatically control the sand discharge and pressure relief operations of the hydrocyclone sand separator during operation.

[0005] In a first aspect, this application provides a wireless IoT control method for a hydrocyclone desander, applied to a desandering device. The desandering device includes a hydrocyclone desander, which includes an oil / gas fluid inlet, an oil / gas fluid outlet, and a sand discharge port. The hydrocyclone desander's piping is equipped with a first pressure transmitter and a second pressure transmitter.

[0008] In conjunction with the first aspect, one possible implementation further includes: if the fluctuation range of the pressure difference within a historical preset time period is greater than a preset range, then generating a third execution command; controlling the electric throttle valve to open to a third preset opening degree at a third speed according to the third execution command; and closing the electric throttle valve if the fluctuation range decreases to below the preset range.

[0009] In conjunction with the first aspect, one possible implementation further includes: if the increase in pressure difference within a set unit time period is greater than a preset increase, then generating a fourth execution command; controlling the electric throttle valve to open to a half-open degree at the maximum opening speed according to the fourth execution command; and closing the electric throttle valve if the increase in pressure difference decreases to below the preset amplitude.

[0011] In conjunction with the first aspect, in one possible implementation, the step of controlling the opening condition of the electric throttle valve according to the instruction strategy issued by the upper server if the instruction strategy issued by the upper server is obtained includes: ignoring the execution strategy called by the pressure difference if the instruction strategy issued by the upper server is obtained; obtaining the corresponding opening instruction according to the instruction strategy; and controlling the opening condition of the electric throttle valve according to the opening instruction.

[0012] Secondly, this application provides a wireless IoT control system for a hydrocyclone desander, applied to a desandering device. The desandering device includes a hydrocyclone desander, which includes an oil / gas fluid inlet, an oil / gas fluid outlet, and a sand discharge port. The hydrocyclone desander's internal piping is equipped with a first pressure transmitter, a second pressure transmitter, and a vibration sensor.

[0015] Technical effects of this application:

[0016] I. Gravel is generated during oil and gas extraction. When high-pressure oil and gas mixed with gravel enter a hydrocyclone desander, this application provides real-time monitoring of the pressure at the oil and gas inlet and outlet during the desandering process. The opening of the electric throttle valve can be remotely controlled to regulate sand discharge and pressure relief, eliminating the need for on-site personnel to periodically check and operate the system, saving labor costs and improving safety during production operations. This is particularly suitable for oil and gas field operations. The system allows for remote monitoring of the first and second pressure values ​​at any time, and automatically adjusts the opening of the electric throttle valve based on the pressure difference to achieve automated sand discharge and pressure relief. Simultaneously, it can select an appropriate valve opening strategy based on the coarseness of the gravel in the hydrocyclone desander to accurately match actual working conditions, and uses pressure difference to correct the strategy. The host server can also issue separate commands to the electric throttle valve to remotely control its opening, making the overall operation more automated and intelligent.

[0027] 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.

[0028] An exemplary wireless IoT control method for a cyclone separator is as follows:

[0029] Figure 1 The diagram shown is a schematic representation of the steps of a wireless IoT control method for a cyclone separator according to an embodiment of this application. Figure 2 The diagram shows a structural schematic of a sand removal device according to an embodiment of this application. This application provides a wireless IoT control method for a hydrocyclone sand remover, applied to a sand removal device. The sand removal device includes a hydrocyclone sand remover 2, which includes an oil / gas fluid inlet 201, an oil / gas fluid outlet 202, and a sand discharge port 203. The hydrocyclone sand remover 2's piping is equipped with a first pressure transmitter 204, a second pressure transmitter 205, and a vibration sensor. The vibration sensor can be a piezoelectric vibration sensor (not shown in the figure). The first pressure transmitter 204 monitors the first pressure value of the oil / gas input from the oil / gas fluid inlet 201, and the second pressure transmitter 205 monitors the second pressure value of the oil / gas output from the oil / gas fluid outlet 202. The sand discharge port 203 is equipped with an electric throttle valve 206. The hydrocyclone sand remover 2 is a single-cylinder type. The electric throttle valve 206 is installed at the sand discharge pipe of the hydrocyclone sand remover 2 to proportionally control the pressure relief and sand discharge operation of the sand discharge port 203.

[0030] like Figure 1 As shown, the wireless IoT control method for the hydrocyclone sand separator includes:

[0031] Step 1100: Obtain the first pressure value detected by the first pressure transmitter 204, and obtain the second pressure value detected by the second pressure transmitter 205.

[0032] Step 1200: Obtain vibration data detected by the vibration sensor.

[0033] Step 1300: Extract the first proportion of the first frequency range and the second proportion of the second frequency range based on the vibration data.

[0034] In this step, the first frequency range and the second frequency range are extracted from the spectral data of the vibration data by using filters, thereby obtaining the first proportion and the second proportion of the two frequency ranges in the spectral data.

[0035] Step 1400: If the first proportion is greater than the preset proportion, a coarse sand signal is generated, and a first execution strategy with a large opening and short duration is generated.

[0036] In this step, if the first proportion is greater than the preset proportion, it is considered that there is too much coarse sand and a coarse sand signal is generated. That is, the frequency in the first frequency range is less than the frequency in the second frequency range, meaning that the frequency corresponding to the vibration spectrum generated by the coarse sand is lower than the frequency generated by the fine sand. The preset proportion can be set to any value between 51% and 100%. The control strategy for the opening of the electric throttle valve 206 is a large opening and short duration. The mechanism is that the opening is large enough to ensure that coarse sand can be discharged to achieve sand discharge and pressure relief, while the short opening duration can avoid excessive discharge.

[0037] Step 1500: If the second proportion is greater than the preset proportion, a fine sand signal is generated, and a second execution strategy with a small opening and long duration is generated.

[0038] In this step, when the second proportion is greater than the preset proportion, it is considered that there is more fine sand and a fine sand signal is generated. That is, the frequency in the second frequency range is higher than the frequency in the first frequency range, and the frequency corresponding to the vibration spectrum generated by the fine sand is higher than the frequency generated by the coarse sand. The preset proportion can be set to any value between 51% and 100%. The control strategy for the opening of the electric throttle valve 206 is a small opening with a long duration. The mechanism is that a small opening can discharge fine sand to achieve sand discharge and pressure relief, and since the opening is small, increasing the opening time can ensure sufficient pressure relief.

[0039] In some embodiments, coarse sand particles are large, with high mass and inertia, resulting in a low impact frequency when they strike the pipe wall, dominated by low-frequency vibration, typically concentrated in the range of 10 to 100 Hz. Fine sand particles are small, with low mass and inertia, resulting in a high impact frequency when they strike the pipe wall, dominated by high-frequency vibration, typically concentrated in the range of 100 to 1000 Hz.

[0040] Step 1600: Call the corresponding dynamic compensation parameters according to the pressure difference.

[0041] In this step, the dynamic compensation parameter is directly proportional to the pressure difference; that is, the greater the pressure difference, the greater the dynamic compensation parameter. For example, the maximum pressure difference that the pipeline of cyclone separator 2 can withstand at the time of manufacture is P. max The pressure difference is X%P max At that time, the dynamic compensation parameter is 1. For every 1 percentage point increase in X% corresponding to the pressure difference, the dynamic compensation parameter increases by Y. The values ​​of X% and Y are set according to the specific requirements of sand discharge and pressure relief. The higher the sensitivity and rate requirements of sand discharge and pressure relief, the larger X% and Y will be.

[0042] Step 1700: Based on the dynamic compensation parameters, correct the baseline duration and baseline opening corresponding to the first execution strategy or the second execution strategy.

[0043] In this step, since the pressure difference reflects the severity of blockage in the desanding device, a larger pressure difference indicates more severe blockage and higher internal pipeline pressure. Further correction is made using dynamic compensation parameters. The first and second execution strategies each have their corresponding reference duration and reference opening, which are set at the factory or during commissioning testing. For example, the first execution strategy is a large opening, short duration type, with a reference duration set to 10 seconds and a reference opening set to 80%; the second execution strategy is a small opening, long duration type, with a reference duration set to 30 seconds and a reference opening set to 30%. This step dynamically corrects either the first or second execution strategy based on the pressure difference; a larger pressure difference results in a longer corrected reference duration and a larger reference opening.

[0044] Step 1800: If the pressure difference is greater than the reference pressure difference, the opening of the electric throttle valve 206 is controlled based on the modified first or second execution strategy.

[0045] In this step, a pressure difference greater than the reference pressure difference is used as the trigger condition for sand discharge and pressure relief. When this condition is triggered, the electric throttle valve 206 is opened to discharge sand and relieve pressure according to the modified first or second execution strategy. The reference pressure difference can be set to a value between 10% and 50% of the safe pressure difference that the cyclone separator 2 can withstand, as set by the factory. If the pressure difference is greater than the reference pressure difference, sand discharge and pressure relief are required.

[0046] Step 1900: If the instruction policy issued by the host server is obtained, the opening degree of the electric throttle valve 206 is controlled according to the instruction policy.

[0047] In this embodiment, gravel is generated during oil and gas extraction. When high-pressure oil and gas mixed with gravel enter the hydrocyclone desander 2, the hydrocyclone desander 2 performs desandering operations. This embodiment monitors the pressure of the oil and gas fluid inlet 201 and outlet 202 in real time throughout the process. The opening of the electric throttle valve 206 can be remotely controlled, thereby controlling the sand discharge port 203 for sand discharge and pressure relief. This eliminates the need for operators to regularly check and operate on-site, saving labor costs and improving safety during production operations, making it particularly suitable for oil and gas field operations. The first and second pressure values ​​can be viewed remotely at any time, and the opening of the electric throttle valve 206 can be automatically adjusted according to the pressure difference to achieve automated sand discharge and pressure relief. At the same time, an appropriate valve opening strategy can be selected according to the coarseness of the gravel in the hydrocyclone desander 2 to accurately match the actual working conditions, and the execution strategy can be corrected using the pressure difference. The host server can also issue separate command strategies to the electric throttle valve 206 to remotely control its opening. In summary, this embodiment makes the overall operation more automated and intelligent.

[0048] Figure 3 The illustration shows a first embodiment of valve body control based on pressure difference. In one embodiment, as... Figure 3 As shown, the wireless IoT control method for the hydrocyclone sand separator also includes:

[0049] Step 1301: If the pressure difference exceeds the preset pressure difference threshold for a first preset time period, then generate the first characteristic parameter.

[0050] Step 1302: Adjust the first execution strategy or the second execution strategy according to the first characteristic parameter so that the opening speed of the corresponding electric throttle valve 206 is the first speed.

[0051] Step 1303: If the pressure difference drops to zero, close the electric throttle valve 206.

[0052] In this embodiment, the preset differential pressure threshold can be set to a value between 70% and 90% of the safe differential pressure that the hydrocyclone desander 2 can withstand, as set at the factory. If the differential pressure exceeds the preset threshold, the hydrocyclone desander 2 may be damaged. In this embodiment, if the differential pressure is too large and persists for a first preset time period, it indicates that there is too much sand and gravel inside the hydrocyclone desander 2, causing blockage. It is necessary to open the electric throttle valve 206 as soon as possible to discharge sand and relieve pressure. However, it is also necessary to consider the problem that opening the valve too quickly under large differential pressure conditions may damage the valve body. At this time, the electric throttle valve 206 is opened gradually at a first speed to avoid damage to the valve body caused by transient opening under large differential pressure conditions. The first speed can be set to a value between 40% and 70% of the full opening speed. After complete pressure relief, when the differential pressure drops to zero, it indicates that sufficient sand discharge and pressure relief have been performed. At this time, the electric throttle valve 206 is closed, and the hydrocyclone desander 2 continues to perform hydrocyclone sand removal operations. The first preset time period can be set to a value between 2s and 5s.

[0053] Figure 4 The illustration shows a second embodiment of valve body control based on pressure difference. In one embodiment, as shown... Figure 4 As shown, the wireless IoT control method for the hydrocyclone sand separator also includes:

[0054] Step 1311: If the pressure difference remains within a preset percentage range of the preset pressure difference threshold for a second preset time period, then generate the second characteristic parameter.

[0055] Step 1312: Adjust the first execution strategy or the second execution strategy according to the second characteristic parameter so that the opening speed of the corresponding electric throttle valve 206 is the second speed.

[0056] Step 1313: If the pressure difference decreases to the safe percentage range, close the electric throttle valve 206. The value corresponding to the safe percentage range is less than the value corresponding to the preset percentage range.

[0057] In this embodiment, the preset differential pressure threshold can be set to a value between 70% and 90% of the safe differential pressure that the hydrocyclone desander 2 can withstand, as set at the factory. If the differential pressure exceeds the preset differential pressure threshold, the hydrocyclone desander 2 may be damaged. When the differential pressure reaches a preset percentage range of the preset differential pressure threshold (e.g., a value between a safe percentage and 99% of the preset differential pressure threshold) and persists for a second preset time period, it can be considered that the differential pressure is not large and the risk of damage to the hydrocyclone desander 2 is low. At this time, the electric throttle valve is controlled to open at a second speed. In this embodiment where the risk of damage is low, the second speed is less than the aforementioned first speed, that is, the electric throttle valve 206 gradually opens at a second speed that is slower than the aforementioned first speed, which can slow down the pressure release and further protect the electric throttle valve 206. When the differential pressure drops to a safe percentage range, which can be set to 0% to 30%, the electric throttle valve 206 is closed, and the hydrocyclone desander 2 continues to perform hydrocyclone desandering operations. When the pressure difference reaches a preset percentage range of the preset pressure difference threshold for a second preset time period, steps 1311, 1312, and 1313 are executed again. The second preset time period can be set to a value between 2s and 5s.

[0058] In some embodiments, when the pressure difference reaches a preset percentage range of a preset pressure difference threshold and does not continue for a second preset time period, and then the pressure difference continues to rise and exceeds the preset pressure difference threshold for a first preset time period, steps 1301, 1302, and 1303 are executed.

[0059] Figure 5 The illustration shows a third embodiment of valve body control based on pressure difference. In one embodiment, as shown... Figure 5 As shown, the wireless IoT control method for the hydrocyclone sand separator also includes:

[0060] Step 1321: If the fluctuation range of the pressure difference within the historical preset time period is greater than the preset range, then generate the third execution instruction.

[0061] Step 1322: Control the electric throttle valve 206 to open to the third preset opening degree at the third speed according to the third execution command.

[0062] Step 1323: If the fluctuation amplitude decreases to below the preset amplitude, close the electric throttle valve 206.

[0063] In this embodiment, the changes in pressure difference over a historical preset time period are traced. This historical preset time period can be set to a value between 2 and 8 seconds in the past. If the fluctuation amplitude within the historical preset time period is greater than the preset amplitude, it indicates that the pressure difference fluctuation is too large, and stabilization measures need to be taken. The preset amplitude can be set to a 10% change in pressure difference within 1 second. The third speed can be set to be less than the first and second speeds, and the third preset opening can be set to be less than the first and second preset openings. Whenever step 1321 occurs, step 1322 is executed once, thereby stabilizing the pressure difference and preventing excessively frequent and large pressure changes inside the cyclone separator 2. In this embodiment, the priority is higher than steps 1400 to 1800. That is, when step 1321 is triggered, the execution of the first or second execution strategy is ignored, and steps 1322 and 1323 are executed instead.

[0064] Figure 6 The illustration shows a fourth embodiment of valve body control based on pressure difference. In one embodiment, as shown... Figure 6 As shown, the wireless IoT control method for the hydrocyclone sand separator also includes:

[0065] Step 1331: If the increase in pressure difference within a set unit time period is greater than the preset increase, then generate the fourth execution instruction.

[0066] Step 1332: Control the electric throttle valve 206 to open to half-opening degree at maximum opening speed according to the fourth execution command.

[0067] Step 1333: If the increase in pressure difference decreases to below the preset value, then close the electric throttle valve 206.

[0068] In this embodiment, the real-time status of the pressure difference is monitored. If the increase in the pressure difference within a set unit time period is greater than a preset increase, it indicates that the pressure difference fluctuation is too large. The set unit time period can be set to a value between 1s and 3s. For example, if the set unit time period is 1s, then in step 1331, the fluctuation amplitude of the pressure difference within 1s is monitored in real time. If the increase is greater than the preset increase, a fourth execution command is generated. To address the issue of excessive real-time fluctuation in this embodiment, the electric throttle valve 206 is controlled to open to a half-open degree at its maximum opening speed to discharge sand and relieve pressure, thereby stabilizing the pressure difference. Opening the electric throttle valve 206 at its maximum opening speed allows it to discharge sand and relieve pressure quickly in real time to rapidly adjust the pressure difference. A half-open degree ensures sufficient sand discharge and pressure relief without excessive pressure relief. In step 1333, if the pressure difference increase is less than or equal to the preset amplitude, the pressure difference fluctuation is considered small, and sand discharge and pressure relief are unnecessary. The electric throttle valve 206 is then closed to continue swirling sand removal. In this embodiment, the priority is higher than steps 1400 to 1800. That is, when step 1331 is triggered, the execution of the first execution strategy or the second execution strategy is ignored, and steps 1332 and 1333 are executed instead.

[0069] Figure 7 The diagram illustrates a power supply method according to one embodiment. In one embodiment, the sand removal device further includes a storage battery and a solar power module, such as... Figure 7 As shown, the wireless IoT control method for the hydrocyclone sand separator also includes:

[0070] Step 160: If it is a sunny day, control the solar power module to supply power.

[0071] This step can be powered by solar energy, which can save battery power.

[0072] Step 170: If it is currently cloudy, control the battery to provide power.

[0073] On cloudy days, due to insufficient solar energy, this step switches to battery power.

[0074] Step 180: If the battery power drops to a preset range, control the battery to provide pulse power.

[0075] This step involves providing pulsed power to the battery when its charge is low, ensuring power supply while achieving a certain energy-saving effect.

[0076] Figure 8 The diagram illustrates the steps of a method for controlling a valve body according to instructions issued by a host server. In one embodiment, as shown... Figure 8 As shown, step 1900 includes:

[0077] Step 151: If the instruction policy issued by the upper server is obtained, then ignore the execution policy of the pressure difference call.

[0078] Step 152: Obtain the corresponding opening instruction according to the instruction strategy.

[0079] Step 153: Control the opening of the electric throttle valve 206 according to the opening command.

[0080] In this embodiment, the instruction strategy can be made by a remote computer or a remote mobile phone. In this embodiment, the opening and closing of the electric throttle valve 206 is executed with the instruction strategy as the highest priority, and the automation instructions of other steps 1400 to 1800 are ignored during the process.

[0081] An example of a wireless IoT control system for a cyclone separator is as follows:

This application also provides a wireless IoT control system for a hydrocyclone desander, applied to a desandering device. The desandering device includes a hydrocyclone desander 2, which includes an oil / gas fluid inlet 201, an oil / gas fluid outlet 202, and a sand discharge port 203. The hydrocyclone desander 2's piping is equipped with a first pressure transmitter 204, a second pressure transmitter 205, and a vibration sensor. The first pressure transmitter 204 monitors the first pressure value of the oil / gas input from the oil / gas fluid inlet 201, and the second pressure transmitter 205 monitors the second pressure value of the oil / gas output from the oil / gas fluid outlet 202.
