Description

Technical Field

[0001] This application relates to the field of geological exploration and development technology, and in particular to a device for monitoring the mobility of pore water in rocks. Background Technology

[0002] Rock gas is an important unconventional natural gas resource. During the rock gas extraction process, the mobility of pore water in the rock directly affects the effective development of the gas reservoir. Before extraction, it is necessary to monitor the mobility of pore water in the rock sample.

[0003] In existing technology, rock samples are placed in a box, and pore water flowing out of the box is collected directly by core centrifugation. Then, the anions and cations in the collected pore water are measured, and the total salinity (TDS) is calculated. The higher the TDS value, the greater the viscosity of the pore water and the worse the mobility of the pore water.

[0004] However, the centrifugation process is carried out entirely at room temperature. The difference between room temperature and underground temperature will result in different mobility of the collected pore water, ultimately leading to poor accuracy in detecting the mobility of pore water. Summary of the Invention

[0023] This application provides a rock pore water mobility monitoring device, which consists of an openable and closable housing containing multiple collectors, a processing module, multiple detectors, and multiple temperature controllers. The processing module is located outside the housing, and the detectors are individually housed within each collector; that is, each collector contains one detector.

[0045] Rock gas is an important unconventional natural gas resource. During the rock gas extraction process, the mobility of pore water in the rock directly affects the effective development of the gas reservoir. Before extraction, it is necessary to monitor the mobility of pore water in the rock sample.

[0046] In existing technologies, rock samples are placed in a core centrifuge chamber, and the pore water flowing out of the chamber is collected directly. The anions and cations in the collected pore water are then measured to calculate the total salinity (TDS). A higher TDS value indicates greater pore water viscosity and poorer pore water mobility. However, the core structure is damaged during centrifugation, leading to inaccurate TDS calculations and ultimately distorting the assessment of pore water mobility.

[0047] This application provides a rock pore water mobility monitoring device, which consists of an openable and closable housing containing multiple collectors, a processing module, multiple detectors, and multiple temperature controllers. The processing module is located outside the housing, and the detectors are individually housed within each collector; that is, each collector contains one detector. The collectors cover the surface of the rock sample. The temperature controllers and collectors are all located inside the housing, and each detector and processing module is electrically connected. During testing, a cubic rock sample is selected, with its dimensions matching the end of the collector covering the sample's surface. The rock sample is placed inside the chamber, and the collector contacts the sample's surface from different directions. After closing the chamber, the processing module is activated. The processing module controls a temperature control to change the temperature inside the chamber, with a preset temperature simulating the underground temperature at different depths. The movable portion of pore water in the rock sample migrates outward and enters the collector at different preset temperatures, allowing the detector to detect the amount of movable pore water in the rock sample at different preset temperatures. Simultaneously, multiple collectors cover the surface of the rock sample from different directions, allowing multiple detectors to simultaneously detect the amount of movable pore water in different directions. Finally, the processing module calculates the amount of movable pore water, achieving the detection of the amount of movable pore water in rock samples at different temperatures. This solves the problem of distortion in the detection of pore water mobility and improves the accuracy of pore water mobility detection.

[0048] The embodiments of this application are described below with reference to the accompanying drawings.

[0049] Reference Figures 1 to 3 As shown, in some embodiments, the device includes an openable and closable housing 100, with multiple collectors 200 disposed inside the housing 100. These collectors 200 respectively cover different surfaces of the rock sample 600, and some collectors 200 are used to collect liquid flowing from the corresponding surface of the rock sample 600. A processing module 300 is disposed outside the housing 100. Multiple detection elements 400 are disposed inside the collectors 200 and are used to detect the humidity inside the collectors 200. The multiple detection elements 400 are electrically connected to the processing module 300. Multiple temperature control elements 500 are disposed inside the housing 100 and are used to heat the housing 100. The multiple temperature control elements 500 are electrically connected to the processing module 300. The processing module 300 is used to calculate the pore water mobility of the rock sample 600 based on the temperature inside the housing 100 and the humidity inside the collectors 200.

[0050] The closable enclosure 100 can be made of stainless steel with excellent corrosion resistance, strength and sealing performance. As a sealed protective carrier, the enclosure 100 provides independent installation space for the internal collection component 200, detection component 400 and temperature control component 500, isolating it from external environmental interference. At the same time, in the closed state, it works with the temperature control component 500 to achieve a constant temperature or variable temperature monitoring environment, which improves the portability and maintainability of the device and makes it suitable for rapid deployment in complex construction environments such as field, underground and deep underground.

[0051] The collector 200 is used to collect pore water seeping from rock pores and is the core of the monitoring sample acquisition. The collector 200 can be made of the same material as the housing 100. The collector 200 can temporarily store and guide pore water, gathering the dispersed pore water to the detection area of ​​the detector 400 to obtain an effective sample of rock pore water, avoiding the mixing of external water bodies (surface water, fissure water) and ensuring the consistency between the sample and the monitoring target (rock pore water).

[0052] The detection element 400 can be a humidity sensor. By detecting the humidity in the collection element 200, the pore water can be monitored, providing core basis for the analysis of rock hydrogeological characteristics, realizing automated detection, replacing manual sampling and laboratory testing, improving monitoring efficiency, and adapting to long-term and continuous monitoring needs.

[0053] The temperature control unit 500 can be a heating element, which is used to change the temperature inside the chamber 100. The temperature is adjusted according to the instructions of the processing module 300. It can simulate the real temperature environment of the formation, eliminate the interference of external temperature fluctuations of the chamber 100 on pore water detection, and can also carry out variable temperature tests to study the changes in pressure, water quality and seepage characteristics of rock pore water at different temperatures.

[0054] The processing module 300 can be divided into a temperature controller 500 for controlling temperature control and a data unit for collecting and processing data from the detection component 400. This enables the device to operate fully automatically without human intervention on-site, making it suitable for scenarios that are difficult to monitor manually, such as deep, high-risk, and field environments. It also enables remote viewing, tracing, and analysis of data, providing timely and traceable data support for engineering decisions and geological research.

[0055] This application provides a rock pore water mobility monitoring device, which comprises an openable and closable housing 100, within which are arranged multiple collectors 200, a processing module 300, multiple detectors 400, and multiple temperature control devices 500. The processing module 300 is located outside the housing 100. Each detector 400 is correspondingly located within one of the collectors 200, meaning each collector 200 contains one detector 400. The collectors 200 cover the surface of a rock sample 600. The temperature control devices 500 and the collectors 200 are both located inside the housing 100. All detectors 400 in the temperature control devices 500 are electrically connected to the processing module 300.

[0056] During testing, a cubic rock sample 600 is selected, the size of which matches the end of the collector 200 covering the surface of the rock sample 600. The rock sample 600 is placed into the chamber 100, with the collector 200 contacting the surface of the rock sample 600 from different directions. After closing the chamber 100, the processing module 300 is activated. The processing module 300 controls the temperature control 500 to change the temperature inside the chamber 100. The preset temperature simulates the underground temperature at different depths. The movable pore water in the rock sample 600 migrates outward at different preset temperatures. The water is moved into the collection element 200, allowing the detection element 400 to detect the mobility of pore water in the rock sample 600 at different preset temperatures. Simultaneously, multiple collection elements 200 cover the surface of the rock sample 600 in different directions, enabling multiple detection elements 400 to simultaneously detect the mobility of pore water in different directions of the rock sample 600. Finally, the processing module 300 calculates the mobility of pore water, achieving the detection of the mobility of pore water in the rock sample 600 at different temperatures. This solves the problem of distortion in the detection of pore water mobility and improves the accuracy of pore water mobility detection.

[0057] Reference Figure 1 and Figure 2 As shown, in some embodiments, at least one collection member 200 is movably disposed within the housing 100; the ends of multiple collection members 200 facing the rock sample 600 together enclose a receiving cavity 210 for receiving the rock sample 600, the receiving cavity 210 being matched with the rock sample 600.

[0058] In this embodiment, in order to ensure that multiple collection elements 200 abut against different sides of the rock sample 600, at least one collection element 200 is movably disposed within the housing 100. It is understood that the rock sample 600 can be a cubic structure. In order to ensure that all six sides of the rock sample 600 abut against the collection elements 200, at least one collection element 200 is configured to be movable relative to the housing 100. In use, this collection element 200 is removed, and after the remaining five sides of the rock sample 600 are sealed against the five fixed collection elements 200, the removed collection element 200 is reversed so that each side of the rock sample 600 abuts against one collection element 200, thereby realizing the collection of the mobility of pore water in different directions of the rock sample 600.

[0059] The six collection components 200, with their ends facing the rock sample 600, together form a receiving cavity 210. During testing, the rock sample 600 is placed inside the receiving cavity 210, meaning that the size of the receiving cavity 210 matches the rock sample 600. The end of the phone holder facing the rock sample 600 matches the side of the rock sample 600, allowing the side of the rock sample 600 to seal against the end of the collection component 200. Pore water migrating from the rock sample 600 can all flow into the collection component 200, ensuring data accuracy.

[0060] Reference Figure 2 As shown, in some embodiments, the collector 200 is conical, with its large-diameter end facing the rock sample 600; or, the sidewalls of the collector 200 are conical, and a through hole 220 is provided on the end of the collector 200 facing the rock sample 600, the through hole 220 being used for liquid flowing out through the surface of the corresponding rock sample 600.

[0061] In this embodiment, the collector 200 is conical, and the large-diameter end of the collector 200 is directed toward the rock sample 600. The large-diameter end of the collector 200 can be a hollow structure to facilitate the passage of pore water. Alternatively, a filter structure can be provided at the end of the hollow structure near the rock sample 600 to filter impurities carried out by the pore water from the rock sample 600, thus preventing impurities from affecting the test results.

[0062] Alternatively, the collector 200 can be formed into a cone shape by its sidewalls, and through holes 220 are provided on the sidewalls that abut against the rock sample 600. The through holes 220 are used to allow pore water flowing out from the surface of the corresponding rock sample 600 to pass through. The through holes 220 can block some larger impurities from entering the collector 200, thus optimizing the filtration structure and preventing impurities from entering the collector 200 and affecting the test results.

[0063] Reference Figure 2 and Figure 3As shown, in some embodiments, at least one first connecting part 230 is provided on the collection component 200, and at least one second connecting part 110 is provided inside the box body 100, and the first connecting part 230 and the second connecting part 110 are movably connected.

[0064] In specific implementation, in order to place the collection component 200 inside the housing 100, at least one first connecting part 230 is provided on the end of the collection component 200 facing away from the rock sample 600, and at least one second connecting part 110 is provided on each side of the housing 100. The first connecting part 230 and the second connecting part 110 are connected to each other. It is worth mentioning that at least one collection component 200 needs to be movably connected to the housing 100. Thus, in the connection between the collection component 200 and the housing 100, at least one first connecting part 230 is movably connected to the second connecting part 110, and the remaining first connecting parts 230 are fixedly connected to the second connecting parts 110. In use, the rock sample 600 can be placed into the receiving cavity 210 simply by moving the movably connected first connecting parts 230 and second connecting parts 110 to correspond to each other.

[0065] Reference Figure 2 and Figure 3 As shown, in some embodiments, a first connector 700 is also included, and the first connecting part 230 and the second connecting part 110 are movably connected through the first connector 700.

[0066] To achieve the movable connection between the first connecting part 230 and the second connecting part 110, the device further includes a first connecting member 700, which can be a locking bolt. That is, the first connecting member 700 is disposed on the first connecting part 230. The movable connection between the first connecting part 230 and the second connecting part 110 is achieved by the first connecting member 700 moving relative to the second connecting part 110. At the same time, after the rock sample 600 is placed into the receiving cavity 210, the movable first connecting part 230 needs to be fixed in the current position of the second connecting part 110. The device achieves this by tightening the first connecting member 700.

[0067] Reference Figure 2 and Figure 3 As shown, in some embodiments, one of the first connector 700 and the second connector 110 is a groove, and the other is a slider that matches the groove.

[0068] In a specific implementation, the first connecting part 230 is movably connected to the second connecting part 110 via the first connecting member 700. The first connecting member 700 is movable relative to the second connecting part 110. One of the first connecting member 700 and the second connecting part 110 can be a slide groove, and the other can be a slider that matches the slide groove. For example, the first connecting member 700 is a slider, and the second connecting part 110 is a slide groove. The first connecting member 700 can slide on the second connecting part 110, realizing the movable connection between the first connecting part 230 and the second connecting part 110, so that the rock sample 600 can be placed into the receiving cavity 210 during testing.

[0069] Reference Figure 2 As shown, in some embodiments, the collecting member 200 is further provided with a third connecting part 240, which is disposed inside the collecting member 200 and connected to the detection member 400, which is disposed inside the collecting member 200.

[0070] In this embodiment, the collection component 200 is also provided with a third connecting part 240, which is used to install the detection component 400. It is worth mentioning that the third connecting part 240 is located inside the collection component 200 at the end opposite to the rock sample 600. The detection component 400 on the third connecting part 240 is also located inside the collection component 200, which facilitates the detection component 400 to detect the pore water humidity inside the collection component 200. At the same time, it provides accurate installation and fixed positioning of the detection component 400, ensuring the accuracy and consistency of the detection data while preventing sample leakage and contamination, and ensuring sample purity.

[0071] Reference Figure 1 and Figure 2 As shown, in some embodiments, multiple wires 710 are also included, with the detection element 400 and the processing module 300 electrically connected via the wires 710, and the temperature control element 500 and the processing module 300 electrically connected via the wires 710.

[0072] In this embodiment, the detection element 400 is electrically connected to the processing module 300 via a wire 710, and the temperature control element 500 is electrically connected to the processing module 300 via a wire 710. It can be understood that the processing module 300 may include a temperature controller that controls the temperature control element 500 and a data unit that collects and processes data from the detection element 400. The temperature control element 500 is electrically connected to the temperature controller via a wire 710, and the detection element 400 is electrically connected to the data unit via a wire 710. The temperature controller and the data unit can be powered independently and do not interfere with each other.

[0073] Reference Figure 2 As shown, in some embodiments, an inlet / outlet hole 241 is provided on the third connecting part 240, and the inlet / outlet hole 241 is used for the wire 710 of the detection element 400 to enter and exit the collecting element 200.

[0074] In practical implementation, the detection element 400 is installed inside the collection element 200 through the third connecting part 240. In order to realize the electrical connection between the detection element 400 and the external processing module 300, the third connecting part 240 is provided with an inlet hole 241. The inlet hole 241 is used for the wire 710 connecting the detection element 400 and the processing module 300 to enter and exit the collection element 200. The electrical connection between the detection element 400 and the processing module 300 is realized while ensuring the internal sealing of the collection element 200, eliminating sample leakage and contamination, and ensuring sample purity.

[0075] Reference Figure 3 As shown, in some embodiments, the openable and closable housing 100 is provided with a plurality of mounting parts 120, which are used to mount the temperature control unit 500.

[0076] In practical implementation, to house the temperature control unit 500 inside the enclosure 100, the openable enclosure 100 is also equipped with multiple mounting parts 120 for mounting the temperature control unit 500. It is understood that the mounting parts 120 are located at the bottom of the enclosure 100, on both sides of the second connecting part 110 at the bottom, and do not interfere with each other. The mounting parts 120 can be grooves adapted to the temperature control unit 500 or snap-fit ​​connections to the temperature control unit 500. The mounting parts 120 achieve precise positioning and stable fixation of the temperature control unit 500, ensuring the working accuracy of the temperature control unit 500 and improving the temperature control stability of the enclosure 100.
