[0023] This invention provides a device for simulating the genesis of high-salinity water in deep coal seams. Figures 1 to 3 This is an embodiment of the device for simulating the origin of high-mineralization water in deep coal seams provided by the present invention.

[0024] The development of deep coalbed methane is often accompanied by the production of highly salinized formation water, which has a significant impact on coalbed methane enrichment and production. Existing research indicates that evaporation concentration and water-rock interaction are the main mechanisms for the formation of highly salinized water in deep coal-bearing reservoirs. Furthermore, differences in coal and rock composition formed in different sedimentary environments directly affect the water-rock interaction process. Therefore, establishing a systematic simulation device to study the formation process of highly salinized water with different coal and rock compositions in high-temperature and high-pressure reaction environments is of great significance for the selection of exploration sites for deep coalbed methane.

[0025] Please refer to the following: Figures 1 to 3The deep coal seam high-mineralization water formation simulation device 100 includes a reaction vessel, a storage tank 16, a temperature control structure, a pressure control structure, a collection structure, a detection device 4, and a liquid pump. The storage tank 16 stores low-mineralization water. The temperature control structure includes a heating device 20 and a temperature detection device 6. The heating device 20 is mounted on the reaction vessel 1 to heat it. The temperature detection device 6 is located inside the reaction vessel 1 to detect the temperature inside the reaction vessel 1. The pressure control structure includes a booster pump 18 and a pressure detection device 5. One end of the booster pump 18 is connected to the reaction vessel 1, and the other end is connected to the storage tank 16, for guiding water towards the reaction vessel 1. Low-mineralized water is transported internally. A pressure detection device 5 is installed inside the reactor 1 to detect the pressure inside the reactor 1. The collection structure includes a cold trap 2, an oil suction block 3, and a multi-stage pressure reducing valve. The inlet of the multi-stage pressure reducing valve is connected to the reactor 1, and the outlet of the cold trap 2 is connected to the outlet of the multi-stage pressure reducing valve. It is used to condense the gaseous products in the reactor 1 to form fluid products. The oil suction block 3 is installed inside the cold trap 2 to absorb liquid hydrocarbons in the fluid products. A detection device 4 is used to detect the composition of formation water in the fluid products in the cold trap 2. The inlet of the liquid pump is connected to the cold trap 2, and the outlet is connected to the detection device 4. It is used to transport the formation water in the cold trap 2 toward the detection device 4.

[0026] The reactor 1 is a sealed container used to hold coal and rock samples and simulate the geological environment. It can be made of high-temperature and high-pressure resistant alloy steel to withstand extreme temperature and pressure conditions during the experiment. The storage tank 16 is a container used to store low-mineralized water. It can be a transparent glass tank with a liquid level gauge for easy observation of liquid level changes. The heating device 20 in the temperature control structure generates heat through resistance wire or electromagnetic induction. The temperature detection device 6 is a thermocouple or infrared temperature sensor used to monitor the internal temperature of the reactor 1 in real time. The booster pump 18 in the pressure control structure generates hydraulic pressure through mechanical transmission. The pressure detection device 5 is a piezoelectric or strain gauge pressure sensor used to precisely control the pressure inside the reactor 1. The multi-stage pressure reducing valve in the collection structure gradually reduces pressure through a multi-stage orifice plate. The cold trap 2 is a device that uses refrigerant or circulating cooling water to condense gaseous products. The oil absorption block 3 is an adsorption module made of hydrophobic and oleophilic materials. The detection device 4 refers to an instrument capable of analyzing the ionic composition of a water sample, and the liquid pump refers to a device that delivers liquid through centrifugal force or piston movement.

[0027] During the experiment, coal and rock samples were placed in reactor 1, and low-mineralized water from storage tank 16 was injected into reactor 1 via booster pump 18. Heating device 20 adjusted the reactor temperature based on feedback from temperature detection device 6 to simulate formation thermal conditions. While booster pump 18 transported low-mineralized water from storage tank 16 to reactor 1, it simultaneously pressurized reactor 1, and at the same time, a suitable amount of low-mineralized water was also supplied to reactor 1 to simulate a high-pressure formation environment. The gaseous products generated by the reaction entered cold trap 2 through a multi-stage pressure reducing valve and condensed into a fluid. Oil absorber 3 absorbed the liquid hydrocarbon components. A liquid pump transported the formation water from cold trap 2 to detection device 4 for ion chromatography analysis, thereby obtaining the mineralization characteristics after evaporation concentration and water-rock interaction. The entire process simulated the formation of high-mineralized water under suitable high temperature and high pressure conditions by adding different coal and rock microstructures and mineral components, and by adjusting the temperature and pressure of the reactor through the cooperation of heating device 20 and booster pump 18, thus mimicking the process of different coal and rock compositions forming high-mineralized water under suitable high temperature and high pressure conditions under different geological backgrounds.

[0028] Therefore, in the technical solution provided by the present invention, the temperature control structure includes a heating device 20 and a temperature detection device 6. The heating device 20 is installed on the reactor 1 for heating the reactor 1. The temperature detection device 6 is installed inside the reactor 1 for detecting the temperature inside the reactor 1. The pressure control structure includes a booster pump 18 and a pressure detection device 5. One end of the booster pump 18 is connected to the reactor 1, and the other end is connected to the storage tank 16 for conveying low-mineralized water into the reactor 1. The pressure detection device 5 is installed inside the reactor 1 for detecting the pressure inside the reactor 1. The collection structure includes a cold trap 2, an oil suction block 3, and a multi-stage pressure reducing valve. The inlet of the pressure valve is connected to the reactor 1, and the outlet of the cold trap 2 is connected to the multi-stage pressure reducing valve. It is used to condense the gaseous products in the reactor 1 to form fluid products. The oil suction block 3 is set in the cold trap 2 to absorb liquid hydrocarbons in the fluid products. The detection device 4 is used to detect the composition of formation water in the fluid products in the cold trap 2. The inlet of the liquid pump is connected to the cold trap 2, and the outlet is connected to the detection device 4. It is used to transport the formation water in the cold trap 2 toward the detection device 4. The synergistic effect of the high-temperature and high-pressure reactor 1 and the precise temperature control system more realistically simulates the formation of high-mineralization water in deep coal seams under different geological backgrounds, which is beneficial to guiding the selection of exploration areas for deep coalbed methane.

[0029] By electrically connecting the pressure detection device 5 and the vent valve 19, a closed-loop feedback control system is constructed, realizing real-time detection and automatic pressure relief when the pressure exceeds the limit, significantly improving the safety and control accuracy of the experimental process. Specifically, in the embodiment of the present invention, the reactor 1 is equipped with a vent valve 19, and the vent valve 19 is electrically connected to the pressure detection device 5.

[0030] Vent valve 19 is a valve device used to control the pressure release inside the reactor 1. Specifically, it can be implemented using an electromagnetically driven or pneumatically driven shut-off valve. Its function is to trigger the vent valve 19 to open rapidly when the pressure detection device 5 detects that the pressure inside the reactor 1 exceeds a preset threshold, thereby rapidly releasing the pressure. When the pressure inside the reactor 1 exceeds the safe range due to water-rock reaction or fluid injection, the pressure detection device 5 generates an electrical signal in real time and transmits it to the control unit of the vent valve 19, triggering the vent valve 19 to open, connecting the reactor 1's interior with the external environment and achieving rapid pressure balance. This linkage mechanism eliminates the need for manual intervention in the pressure regulation process. During the continuous injection of low-mineralization water by the booster pump 18, the pressure inside the reactor 1 can be dynamically maintained within the experimentally set range.

[0031] Furthermore, a first shut-off valve 17 is provided between the booster pump 18 and the reactor 1.

[0032] When the booster pump 18 delivers low-mineralized water to the reactor 1, the first shut-off valve 17 is open, allowing water to flow through; when it is necessary to stop the delivery or perform system maintenance, the first shut-off valve 17 closes to cut off the fluid passage. By controlling the opening and closing of this valve, the amount of water entering the reactor 1 can be precisely regulated, avoiding backflow or excessive injection caused by pressure fluctuations.

[0033] Rapid online analysis of formation water ion composition provides reliable data support for studying the evolution of mineralization during the interaction between water and rock in deep coal seams. It solves the problem that existing technologies cannot monitor the dynamic changes of water chemical characteristics under different sedimentary backgrounds in real time. Specifically, in the embodiments of the present invention, the detection device 4 includes at least an ion chromatograph, which is connected to the outlet end of the liquid pump.

[0034] An ion chromatograph is an analytical instrument used to separate and detect ionic components in a solution. Specifically, it can be implemented using a chromatographic system equipped with a conductivity detector. After different ions are separated by a chromatographic column, the detector measures the change in conductivity to determine the ion concentration. A pump continuously extracts formation water from cold trap 2 and delivers it to the ion chromatograph. Cations and anions in the formation water are separated in the chromatographic column, and the detector generates ion concentration data based on the difference in conductivity. By analyzing the changes in ion composition after the reaction between coal and formation water under different sedimentary environments, the influence of water-rock interaction on salinity can be quantified, thereby establishing a correlation model between different sedimentary backgrounds and the formation mechanism of high-salinity water.

[0035] By setting up multiple independent weighing units and automated valves, accurate quantification and automatic conveying of multi-component materials are achieved. This is especially suitable for complex experimental scenarios that require simulating coal and rock composition variables under various sedimentary environments. Specifically, in the embodiments of this invention, the quantitative structure includes multiple storage tanks 9, multiple weighing components 11, and multiple second shut-off valves 10. Each storage tank 9 is connected to each weighing component 11. Each weighing component 11 includes a weighing tank 1101 and a weighing device 1102. The weighing tank 1101 is located at the bottom of the storage tank 9 and is connected to the storage tank 9 for receiving the material in the storage tank 9. The weighing device 1102 is located at the bottom of the weighing tank 1101 for detecting the weight of the material in the weighing tank 1101. Each second shut-off valve 10 is located between each storage tank 9 and each weighing tank 1101.

[0036] In simulating water-rock interactions under different sedimentary environments, multiple storage tanks 9 store different coal and rock microstructures and mineral compositions. After the second shut-off valve 10 opens, material flows from the storage tanks 9 into the weighing tank 1101. The weighing device 1102 monitors the material weight in real time, and closes the second shut-off valve 10 to stop feeding when the preset value is reached. After each weighing tank 1101 completes weighing, the third shut-off valve 12 opens, allowing the material to enter the stirring device 13 for mixing, forming experimental raw materials with a specific ratio. This process, through the coordinated control of multi-stage valves and the weighing system, achieves precise management of the material ratio and avoids the influence of manual weighing errors on the experimental results.

[0037] Furthermore, each weighing tank 1101 is connected to a stirring device 13 at its bottom, and a third shut-off valve 12 is provided between the stirring device 13 and each weighing tank 1101.

[0038] After the weighing tank 1101 completes the weighing of the material, the third shut-off valve 12 is opened, and the material enters the mixing device 13 under gravity. Once the mixing device 13 is started, the blades thoroughly mix the material to form a homogeneous mixture. The third shut-off valve 12 closes after the material transfer is complete to prevent material from flowing back into the weighing tank 1101 during the mixing process. This structure allows materials from different weighing tanks 1101 to enter the mixing device 13 in batches as needed, achieving precise proportioning and mixing of multi-component materials.

[0039] Furthermore, a collection tank 14 is provided below the stirring device 13, and the collection tank 14 is connected to the stirring device 13. A fourth shut-off valve 21 is provided between the collection tank 14 and the stirring device 13.

[0040] After the mixing device 13 completes the mixing of materials, it forms geological materials similar to those in deep coal seams. Then, the fourth shut-off valve 21 is opened, and the mixed materials flow into the collection tank 14 for temporary storage under the action of gravity. During the mixing process, the fourth shut-off valve 21 of the mixing device 13 remains closed.

[0041] To facilitate material transport, in an embodiment of the present invention, a sample inlet funnel 7 is provided on the top of the reactor 1.

[0042] When simulating the interaction between coal and water under different sedimentary environments, the sample funnel 7 allows researchers to directly add pre-weighed coal powder, mineral additives, or liquid reagents into the reactor 1 without disrupting its overall sealing. For example, when simulating the water-rock reaction of a specific coal seam, different proportions of coal micro-components and minerals can be added in stages through the sample funnel 7, allowing them to react with the low-mineralized water transported by the storage tank 16 under controlled temperature and pressure conditions. The funnel's sealing cover remains closed when not in use, ensuring stable pressure inside the reactor 1. A pipe can be installed between the sample funnel 7 and the reactor 1, with an electrically controlled valve on the pipe, thus creating a sealed space within the reactor 1. A collection tank 14 can also be placed on top of the sample funnel 7, with a feed pipe extending from the bottom of the collection tank 14 to the sample funnel 7. An electrically controlled valve on the feed pipe controls the opening and closing of the collection tank 14 during material transport.

[0043] Furthermore, a guide rail 15 is provided between the sample inlet funnel 7 and the collection tank 14, a slider is provided on the guide rail 15, and a robotic arm 8 is provided on the slider for conveying material from the collection tank 14 toward the sample inlet funnel 7.

[0044] The guide rail 15 is fixedly installed at a preset position between the sample inlet funnel 7 and the collection tank 14. The slider cooperates with the guide rail 15 through rollers or sliding bearings. The robotic arm 8 is mounted on the slider and equipped with a clamping mechanism. When it is necessary to transfer the material in the collection tank 14 to the reaction vessel 1, the robotic arm 8 moves along the guide rail 15 to above the collection tank 14, grabs the material, and moves along the guide rail 15 to the sample inlet funnel 7 to complete the delivery. The entire process is achieved through automated control, avoiding errors introduced by manual operation. The guide rail 15 can be made of stainless steel to enhance corrosion resistance. The slider can be driven by an electric motor or a pneumatic device. The gripping action of the robotic arm 8 can be controlled by a preset program or sensor feedback.

[0045] By combining the valve with the waste liquid collection tank, the automated collection and closed treatment of waste liquid is achieved, reducing the complexity of operation and improving the cleanliness of the experimental environment. Specifically, in the embodiment of the present invention, the bottom of the detection device 4 is provided with a valve, and the outlet end of the valve is provided with a waste liquid collection tank.

[0046] Waste liquid collection tanks are containers used to store waste liquids. Specifically, they can be sealed tanks made of corrosion-resistant materials. They are used to centrally treat residual liquids after testing to avoid environmental pollution. After the testing device 4 completes the composition analysis of the formation water, the bottom valve opens, and the waste liquid flows into the waste liquid collection tank through the outlet. The waste liquid collection tank is sealed to prevent liquid evaporation or leakage. When the valve is closed, it can prevent residual liquid from contaminating subsequent test samples. This structure allows the waste liquid to be centrally collected and safely treated, while reducing the frequency of manual cleaning operations.

[0047] All electrical components mentioned in this application are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and existing publicly disclosed power connection technologies will not be elaborated in the text. The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so this application will not explain the control method and circuit connection in detail. The device is powered on, and the PLC system controls the entire device to operate as expected.
