[0028] In this embodiment, a method for gas sequestration treatment is provided, which is applied to the above computer device. Figure 2 It is a flowchart of the method for gas sequestration treatment according to the embodiment of the present application, and this process includes the following steps:
[0029] Step S202, obtaining the environmental parameters of the target area at the current moment; wherein, the target area refers to the area used to store the gas to be sequestered;
[0030] It should be noted that the target area is the area in the abandoned mine chamber used to store the gas to be sequestered. It may include the entire chamber, or may only include some areas with good geological characteristics in the chamber, such as strata with higher porosity and permeability. When selecting the target area, factors such as the stability of its geological structure, the sequestration potential of the gas, and the degree of isolation from the external environment can be considered. The gas to be sequestered may refer to CO2.
[0031] Environmental parameters cover various physical and chemical properties within the target area, which have direct or indirect impacts on the sequestration efficiency and safety of CO2. Environmental parameters can include: Temperature: Affects the solubility of CO2 and the rate of mineralization reaction. Higher temperatures are conducive to accelerating the mineralization reaction. Pressure: Affects the phase state and solubility of CO2. Under high-pressure conditions, CO2 is more likely to liquefy, increasing the sequestration capacity. CO2 concentration: Reflects the accumulation of CO2 within the target area, used to evaluate the sequestration effect and potential leakage risks; Solution level: For methods relying on solution to sequester CO2, it is necessary to monitor the solution level to ensure sufficient space for CO2 injection. Chemical composition of groundwater: For mineralization sequestration, the types and concentrations of minerals in groundwater affect the mineralization efficiency of CO2. Geological structure (such as fractures, faults, etc.): Affects the flow path of CO2 in rocks and the long-term stability of sequestration.
[0032] Install various types of sensors within the target area for continuously monitoring the above environmental parameters. The sensors can include thermometers, pressure gauges, gas concentration detectors, liquid level gauges, and ground-penetrating radars, etc. The sensor network collects environmental parameters in real time and transmits them to the control system on the ground through wired or wireless communication technologies. The data collection frequency needs to be adjusted according to the complexity and safety requirements of the sequestration operation to ensure the timeliness and reliability of the data.
[0033] Step S204, determine the injection control parameters at the current moment based on the environmental parameters at the current moment and the environmental parameters at the previous moment of the target area at the current moment; wherein, the injection control parameters are used to control the injection state of the gas to be sequestered.
[0034] Among them, environmental parameters within the target area are collected in real time, including but not limited to temperature, pressure, CO2 concentration, solution level, and chemical composition of groundwater, etc., and these data are compared with the data at the previous moment (or multiple historical moments). By comparing the environmental parameters at the current moment with those at the previous moment, analyze the trend and speed of parameter changes. For example, if the pressure rises rapidly in a short period of time, it may indicate that the CO2 injection rate is too fast or the geological structure has changed; on the contrary, if the CO2 concentration gradually decreases, it may mean that CO2 is being effectively sequestered and mineralized.
[0035] It can be understood that the injection control parameters can include the injection rate. Based on the change trend of environmental parameters, dynamically adjust the injection rate of CO2. If a rapid increase in pressure or concentration is monitored, the injection rate of CO2 can be reduced to avoid excessive pressure on the geological structure or rapid leakage of CO2. On the contrary, if the chamber conditions are stable and the sequestration efficiency is high, the injection rate can be appropriately increased to speed up the sequestration progress.
[0036] Exemplarily, according to the changes in environmental parameters (such as groundwater composition and temperature), adjust the formulation and concentration of the sequestration solution to promote the dissolution and mineralization reaction of CO2. For example, increasing the alkaline components of the solution can increase the solubility of CO2 under specific conditions, thereby increasing the sequestration amount.
[0037] In some embodiments, combine the geological structure data (such as fracture distribution and porosity) of the target area and environmental parameters to optimize the injection mode and location of CO2, ensure the uniform distribution of CO2 in the chamber, and avoid local overpressure or premature CO2 leakage.
[0038] In other embodiments, based on the analysis of environmental parameters, evaluate the risks during the sequestration process, such as leakage risk and geological stability risk, and set corresponding safety thresholds. When the environmental parameters approach or exceed these thresholds, automatically adjust the injection control parameters or even temporarily stop the injection to ensure the safety of the sequestration process.
[0039] In an exemplary embodiment, determining the injection control parameter at the current moment based on the environmental parameter at the current moment and the environmental parameter at the previous moment of the target area at the current moment includes: determining the change amount of the environmental parameter based on the environmental parameter at the current moment and the environmental parameter at the previous moment of the current moment; comparing the change amount of the environmental parameter with a preset change amount range, and determining the injection control parameter at the current moment according to the comparison result.
[0040] Among them, through a sensor network installed in the target area, such as temperature sensors, pressure sensors, gas concentration detectors, etc., continuously collect the environmental parameters at the current moment. At the same time, based on the stored environmental parameters at the previous moment (or multiple historical moments), as a comparison benchmark. The recording of historical data is not limited to after the start of the sequestration process, and the environmental parameters before sequestration can also be considered to establish a more complete chamber environment background.
[0041] Compare the environmental parameter at the current moment with the corresponding data at the previous moment, and calculate the change amount of each parameter. The change amount can be an absolute value (such as the temperature rising by 2°C) or a relative change rate (such as the pressure increasing by 10%), depending on the nature of the parameter and the specific requirements of the sequestration system.
[0042] Before the start of the sequestration project, preset the change amount range of each environmental parameter according to the stability of the geological structure, sequestration capacity, physical and chemical properties of CO2, and sequestration target. This range can ensure the safety of the sequestration process without overly restricting the sequestration efficiency. Compare the calculated change amount of the environmental parameter with the preset change amount range to evaluate whether the current sequestration state is within the safe and controllable range.
[0043] If the change amount of one or some environmental parameters exceeds the preset range, this may indicate abnormal situations during the sequestration process, such as a sharp increase in pressure due to too fast CO2 injection rate, or an increased risk of CO2 leakage due to geological structure changes, etc. When the change amount of environmental parameters exceeds the preset safety range, the safety threshold is immediately triggered to automatically adjust the injection control parameters, slow down or suspend the CO2 injection to prevent potential safety risks. If the change amount of parameters is within the safety range but close to the boundary of efficiency optimization, the injection control parameters can be finely adjusted, such as appropriately increasing or decreasing the CO2 injection amount, optimizing the solution type or concentration, to improve the sequestration efficiency without sacrificing safety.
[0044] Considering the long-term dynamic changes of environmental parameters, the sequestration system can have a certain adaptability and be able to dynamically adjust the injection control parameters when environmental conditions change to ensure the continuous effectiveness and safety of the sequestration process. The adjusted injection control parameters are fed back to the gas injection equipment to implement precise control of the injection amount. At the same time, this process should form a closed-loop control mechanism, that is, the adjustment result of the injection control parameters affects the change of environmental parameters again, and then comparison and adjustment are carried out again to ensure that the sequestration process is always in the optimal state.
[0045] The above embodiments reflect the intelligent and automated management in the CO2 sequestration project. Through real-time monitoring and data analysis, it is possible to dynamically adjust to achieve the best sequestration efficiency while ensuring safety. This can not only effectively utilize the sequestration potential of abandoned mine chambers, but also reduce unnecessary costs and risks, providing a more sustainable and efficient solution for addressing global climate change.
[0046] In an exemplary embodiment, determining the injection control parameter at the current moment according to the comparison result includes: in the case where the comparison result is that the change amount of the environmental parameter is within the change amount range, determining the historical injection control parameter as the injection control parameter at the current moment; in the case where the comparison result is that the change amount of the environmental parameter is not within the change amount range, performing an increase or decrease process on the historical injection control parameter, and determining the processing result as the injection control parameter at the current moment.
[0047] It can be understood that when the change amount of environmental parameters is within the preset change amount range, it means that the sequestration process is stable and no abnormal situation occurs. In this case, keeping the injection control parameters unchanged is usually the safest and most economical choice, which can avoid unnecessary operation risks and costs.
[0048] Directly determine the historical injection control parameter, that is, the parameters during the previous sequestration operation (such as CO2 injection rate, solution type and concentration, injection mode, etc.), as the injection control parameter at the current moment to maintain the continuity and stability of the sequestration operation.
[0049] When the change amount of environmental parameters exceeds the preset change amount range, this may indicate abnormal conditions during the sequestration process, such as excessive pressure, abnormal changes in CO2 concentration, or a rapid drop in the solution level, etc. Immediate measures need to be taken to adjust the injection control parameters to ensure the safety and efficiency of the sequestration process.
[0050] Specifically, first check if any safety thresholds have been triggered. If so, immediately take safety measures, such as temporarily stopping the injection of CO2, to avoid possible leakage or damage to the geological structure. After ruling out the immediate safety risks, adjust the injection control parameters according to the specific situation of the abnormality. For example, if the pressure rises too fast, it may be necessary to reduce the injection rate of CO2; if a decrease in the solution level is monitored, it may be necessary to increase the injection amount of the solution; if the change in CO2 concentration is abnormal, it may be necessary to adjust the concentration of the solution or add chemical components that promote mineralization. Generally, the adjustment strategy is based on historical injection control parameters. If the parameter change amount exceeds the range, the historical parameters can be increased or decreased according to preset rules or algorithms. For example, when the pressure rises too fast, reduce the historical CO2 injection rate by 10%; when the solution level drops too fast, increase the historical solution injection amount by 20%, etc. Through calculation and analysis, determine the specific values of the injection control parameters that need to be adjusted, and then determine the adjusted parameters as the injection control parameters at the current moment and immediately apply them to the sequestration process to correct the abnormal situation and restore the stability and safety of the sequestration process.
[0051] In some embodiments, the adjustment of the injection control parameters is not a one-time operation, but a dynamic feedback process. Applying the adjusted parameters to the sequestration process will further affect the change of environmental parameters. Therefore, the sequestration system needs to continuously monitor the environmental parameters, make comparisons and parameter adjustments again based on the latest data until the sequestration process resumes stability.
[0052] In the above embodiments, the process of determining the injection control parameters based on the comparison result between the change amount of environmental parameters and the preset range is the key to realizing intelligent management in the CO2 sequestration project. It not only ensures the safety of the sequestration process, but also improves the efficiency and economy of sequestration, providing strong technical support for addressing global climate change.
[0053] Step S206, based on the injection control parameters at the current moment, control the gas injection device to inject the gas to be sequestered into the target area, where the gas injection device is a device for injecting the gas to be sequestered into the target area.
[0054] In an exemplary embodiment, the injection control parameters include injection rate, pressure, and temperature; based on the injection control parameters at the current moment, controlling a gas injection device to inject the gas to be sequestered into the target area includes: obtaining the gas sequestration amount, and based on the gas sequestration amount, the injection rate, pressure, and temperature at the current moment, controlling the gas injection device to inject the gas to be sequestered into the target area.
[0055] Among them, the gas sequestration amount refers to the total amount of CO2 that can be sequestered in the calculated target area.
[0056] Among them, the injection rate refers to the amount of CO2 gas injected into the target area per unit time, usually expressed in units such as liters per minute (L / min) or cubic meters per hour (m 3 / h). Controlling the injection rate is crucial for avoiding excessive pressure on the geological structure and ensuring uniform distribution of CO2. Pressure: During the sequestration process, the pressure in the target area (such as an abandoned mine chamber) is another key parameter. Controlling the pressure not only concerns the safety of sequestration but also affects the phase state of CO2 and its solubility in the solution, thus affecting the sequestration efficiency. Temperature: The temperature in the target area is equally important because temperature affects the solubility of CO2 and its reaction rate with minerals in the rock, thereby affecting the mineralization sequestration effect.
[0057] Specifically, read the injection control parameters at the current moment, including real-time injection rate, pressure, and temperature, etc., adjust the flow rate (injection rate) of the gas injection device, change the working pressure to maintain the pressure stability in the chamber, optimize the temperature conditions by adjusting the solution type and concentration, etc. The gas injection device performs precise injection of CO2 based on the injection control parameters. For example, the valve opening may be automatically reduced or increased to control the injection rate of CO2; or the pressure of the pump may be adjusted to maintain the pressure stability in the target area; even the solution temperature may be adjusted by heating or cooling devices to optimize the dissolution and mineralization process of CO2.
[0058] In the above steps S202 - S206, the environmental parameters of the target area at the current moment are monitored in real time, and environmental changes in the target area can be detected in a timely manner. By comparing the environmental parameters at the current moment with those at the previous moment, the injection control parameters are dynamically adjusted, and then based on the injection control parameters, the gas injection device is controlled to inject the gas to be sequestered into the target area to promote the sequestration of the gas in the target area, thereby improving the sequestration efficiency.
[0059] In an exemplary embodiment, before obtaining the environmental parameters of the target area at the current moment, the method further includes: determining the geological parameters of the target area; based on the geological parameters, performing a sequestration assessment on the target area to determine the number of fractures and the probability of fracture expansion in the target area, and based on the geological parameters, determining the type of solution for sequestering the gas; and determining the gas sequestration amount in the current area based on the solution type, the number of fractures, and the probability of fracture expansion.
[0060] Among them, the geological parameters include, but are not limited to, the porosity, permeability, rock type, underground water flow direction, fracture distribution, and structural stability of the mine shaft, etc. These parameters are directly related to the storage capacity of CO2 in the target area and the safety of the sequestration process.
[0061] By analyzing the fracture distribution in the target area, the total number and distribution characteristics of the fractures are determined, which will affect the flow path of CO2 and the stability of the sequestration space. The probability of further fracture expansion in the target area during the injection of CO2 is predicted, which is to evaluate the stability of the geological structure during the sequestration process and the risk of CO2 leakage.
[0062] When sequestering CO2 in abandoned mine chambers, certain solutions are usually used to promote the dissolution and mineralization reactions of CO2. Selecting the appropriate solution type is an important step to improve the sequestration efficiency and safety. According to the rock type and chemical composition of the target area, a solution type that can react with the minerals in the rock to accelerate the CO2 mineralization process is selected.
[0063] Based on a comprehensive assessment of the geological parameters, fracture distribution, solution type, and potential fracture expansion probability, the amount of CO2 gas that can be safely sequestered in the target area can be predicted. In some embodiments, the number of fractures and the probability of fracture expansion can be considered to evaluate the impact of fractures on the sequestration capacity. The presence of fractures may increase the sequestration space, but excessive fracture expansion will reduce the stability of the geological structure and increase the risk of CO2 leakage. And according to the degree of improvement of the CO2 dissolution and mineralization efficiency by the selected solution type, the sequestration capacity prediction of the target area is adjusted.
[0064] In an exemplary embodiment, the determining the gas sequestration amount in the current area based on the solution type, the number of fractures, and the probability of fracture expansion includes: determining the solubility of the gas based on the solution type, and determining the solution sequestration amount according to the solubility; determining the fracture sequestration capacity based on the number of fractures and the probability of fracture expansion; and determining the gas sequestration amount in the current area according to the sum of the solution sequestration amount and the fracture sequestration capacity.
[0065] Among them, the solution storage capacity refers to the amount of CO2 stored by dissolving CO2 in a solution and utilizing the storage space of the solution. The choice of solution directly affects the solubility of CO2 and the storage efficiency. Different solution types, such as alkaline aqueous solutions, saline solutions, or specific chemical additive solutions, have different effects on the solubility of CO2. Generally, alkaline solutions can increase the solubility of CO2 because CO2 reacts with alkaline solutions to form carbonates, increasing the dissolution ability of CO2. Based on the solution type, the solubility of CO2 in the solution is calculated. Considering temperature, pressure, and the chemical composition of the solution, these parameters will all affect the solubility of CO2.
[0066] The fracture storage capacity refers to the amount of CO2 gas that can be stored in the fracture space of abandoned mine chambers. The existence of fractures can increase the storage space, but the expansion and connectivity changes of fractures will also affect the safety and efficiency of storage. Based on the number of fractures, the average volume of fractures, and the probability of fracture expansion, the total capacity of CO2 stored in fractures is calculated. The calculation of fracture storage capacity needs to consider the porosity of fractures, the flow characteristics of CO2 in fractures, and the additional storage space that may be increased due to fracture expansion.
[0067] Integrate the data of the solution storage capacity and the fracture storage capacity, taking into account the possible interaction and influence between the two storage methods, such as the solution may fill the fractures and affect the fracture storage capacity. Based on the integrated data, determine the gas storage capacity of the target area. This is usually the sum of the solution storage capacity and the fracture storage capacity.
[0068] Through the description of the above implementation manners, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by means of software plus a necessary general hardware platform. Of course, it can also be implemented by hardware, but in many cases the former is a better implementation manner. Based on such an understanding, the technical solution of the present application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disc), and includes several instructions for causing a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods of the various embodiments of the present application.
