Description

Technical Field

[0001] The present invention relates to a deep-earth monitoring method, and in particular to a deep-earth monitoring method for water drive sources applied in the fields of chemical or physical analysis. Background Technology

[0002] In recent years, my country's industrial production level has been continuously improving, and social development and construction have also been ongoing. In this process, a large amount of mineral resources are needed as support. Under such circumstances, it is crucial to achieve mineral resource exploration more efficiently. In the process of mineral resource exploration, the geological prospecting technology applied has an important impact on the efficiency of mineral exploration.

[0003] Geological exploration mainly refers to the process of exploring mineral resources within a clearly defined area using geological exploration techniques, which is limited by geographical boundaries. This includes resource assessment and total quantity estimation, among other things. Existing methods for deep geological and mineral exploration include core drilling, geophysical and geochemical exploration, hydraulic down-the-hole hammer drilling, X-ray fluorescence, magnetic prospecting, and remote sensing multi-band imaging.

[0004] However, existing deep geological exploration and monitoring technologies cannot monitor and collect long-term stratigraphic change data in deep geology, which reduces the ability of relevant personnel to judge geological changes, reduces the ability to explore deep mineral resources, and reduces the effectiveness of deep geological exploration. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to achieve long-term monitoring and collection of stratigraphic change data of deep geology.

[0006] To address the aforementioned problems, this invention provides a deep-earth monitoring method for water-driven precursor sources. This method involves a deep-earth monitor and a geological migration monitoring system mounted within an exploration controller and working in conjunction with the deep-earth monitor. Specifically, it includes the following steps:

[0007] S1. Drilling: Drilling holes at designated locations according to the exploration requirements;

[0008] S2. Investigate the borehole, and then lower the deep monitoring device into the borehole;

[0009] S3. Obstruction Removal: After the deep monitoring device is lowered to the designated position, the exploration personnel control the operation of the deep monitoring device and the geological migration monitoring system. The geological migration monitoring system controls the entry hole obstruction component on the deep monitoring device to generate a removal action, thereby removing the obstruction from the migration monitoring component.

[0010] S4. Multi-resistance deep geological monitoring,

[0011] S41. Then the geological migration monitoring system controls the migration monitoring component to generate a pre-monitoring action, so that the outer end face of the migration monitoring component extends to the outside of the monitoring outer tube and contacts the geological layer;

[0012] The migration monitoring component senses data on external strata migration and transmits the sensed pre-monitoring pressure data to the geological migration monitoring system via signal transmission cables;

[0013] S42. After a certain period of time, the geological migration monitoring system, based on the acquired pre-monitoring pressure data, controls the migration monitoring component to generate a strong resistance monitoring action to increase the contact force between the outer end of the migration monitoring component and the geological layer;

[0014] The migration monitoring component senses data on the migration of external strata and transmits the sensed strong resistance monitoring pressure data to the geological migration monitoring system via signal transmission cable;

[0015] S43. After a period of time, the geological migration monitoring system, based on the acquired pre-monitoring pressure data, controls the migration monitoring component to generate a weak resistance monitoring action to reduce the contact force between the outer end of the migration monitoring component and the geological layer.

[0016] The migration monitoring component senses data on the migration of external strata and transmits the sensed weak resistance monitoring pressure data to the geological migration monitoring system via signal transmission cable;

[0017] S44. Then, following the cycle of S41-S43 above, long-term monitoring and data transmission of the migration data of deep geological layers are carried out.

[0018] S5. Data Feedback: The geological migration monitoring system divides the pre-monitoring pressure, strong resistance monitoring pressure data, and weak resistance monitoring pressure data in a single cycle into a data feedback group. After each completion, the data feedback group and related monitoring data are output independently.

[0019] The above-mentioned deep-earth monitoring method for water-driven precursors effectively realizes long-term, multiple, multi-resistance data monitoring of stratigraphic migration data, which facilitates exploration personnel to invert and judge the changes of stratigraphic migration data, and can fully and accurately reflect the migration data of deep geological strata.

Furthermore, the multi-resistance data monitoring allows for the precise acquisition of minute stratigraphic migration data, further improving the sensitivity of monitoring data, thereby enhancing exploration results and increasing the economic benefits of deep geological exploration.

Detailed Implementation

[0040] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] Implementation method 1:

[0042] Figure 1-9 The method involves a deep monitoring device 10 and a geological migration monitoring system mounted within an exploration controller 6 and cooperating with the deep monitoring device 10, specifically including the following steps:

[0043] S1. Drilling: Drilling holes at designated locations according to the exploration requirements;

[0044] S2. Investigate the borehole, and then lower the deep monitoring device 10 into the borehole;

[0045] S3. Obstruction Removal: After the deep monitor 10 is lowered to the designated position, the survey personnel control the operation of the deep monitor 10 and the geological migration monitoring system. The geological migration monitoring system controls the entry hole obstruction component 3 on the deep monitor 10 to generate a removal action, thereby removing the obstruction of the migration monitoring component 4.

[0046] S4. Multi-resistance deep geological monitoring,

[0047] S41. Then the geological migration monitoring system controls the migration monitoring component 4 to generate a pre-monitoring action, so that the outer end face of the migration monitoring component 4 extends to the outside of the monitoring outer tube 1 and contacts the geological layer;

[0048] The migration monitoring component 4 senses the data of external strata migration and transmits the sensed pre-monitoring pressure data to the geological migration monitoring system through the signal transmission cable 5.

[0049] S42. After a period of time, the geological migration monitoring system controls the migration monitoring component 4 to generate a strong resistance monitoring action to increase the contact force between the outer end of the migration monitoring component 4 and the geological layer, based on the pre-monitoring pressure data obtained.

[0050] The migration monitoring component 4 senses the data of external strata migration and transmits the sensed strong resistance monitoring pressure data to the geological migration monitoring system through the signal transmission cable 5.

[0051] S43. After a period of time, the geological migration monitoring system, based on the acquired pre-monitoring pressure data, controls the migration monitoring component 4 to generate a weak resistance monitoring action to reduce the contact force between the outer end of the migration monitoring component 4 and the geological layer.

[0052] The migration monitoring component 4 senses the data of external strata migration and transmits the sensed weak resistance monitoring pressure data to the geological migration monitoring system through the signal transmission cable 5.

[0053] S44. Then, following the cycle of S41-S43 above, long-term monitoring and data transmission of the migration data of deep geological layers are carried out.

[0054] The time intervals for pre-monitoring, strong resistance monitoring, and weak resistance monitoring can be adjusted to be the same or follow a certain pattern. This needs to be set in advance by the surveyors, and then the geological migration monitoring system will operate according to this set data.

[0055] S5. Data Feedback: The geological migration monitoring system uses pre-monitoring pressure, strong resistance monitoring pressure data, and weak resistance monitoring pressure data from a single cycle as a data feedback group. Each completed data feedback group, along with related monitoring data, is output independently. Through the combined use of the deep monitor 10, the geological migration monitoring system, and this method, long-term, multi-resistance data monitoring of stratigraphic migration can be effectively achieved during deep geological exploration. This facilitates exploration personnel inverting and judging changes based on stratigraphic migration data, while also effectively improving the reliability and accuracy of monitoring data. It can fully and accurately reflect the migration data of deep geological strata, improving the accuracy of exploration personnel's judgments. Furthermore, through multi-resistance data monitoring, it can accurately collect minute stratigraphic migration data, further improving the sensitivity of monitoring data, thereby promoting exploration results and increasing the economic benefits of deep geological exploration.

[0056] The second implementation method:

[0057] Figure 1-9 The deep monitoring device 10 includes a monitoring outer tube 1, a formation monitoring core 2 fixedly embedded in the monitoring outer tube 1, an entry hole shielding component 3 set at the outer end of the monitoring outer tube 1, and a migration monitoring component 4 set in the formation monitoring core 2 and cooperating with the entry hole shielding component 3. A signal transmission cable 5 is fixedly installed in the formation monitoring core 2, and an exploration controller 6 is fixedly connected to the upper end of the signal transmission cable 5. The exploration controller 6 is equipped with a geological migration monitoring system.

[0058] The geological transport monitoring system includes a monitoring and processing unit. The input end of the monitoring and processing unit is connected to a multi-resistance transport acquisition unit, a basic parameter unit, and an instruction receiving unit. The output end of the monitoring and processing unit is connected to an obstruction control unit, a transport monitoring resistance control unit, and a monitoring data output unit.

[0059] The input end of the multi-resistance migration acquisition unit is connected to the migration monitoring component 4. The input ends of the basic parameter unit and the command receiving unit are both connected to the exploration control end. The output end of the obstruction control unit is connected to the borehole obstruction component 3. The output end of the migration monitoring resistance control unit is connected to the migration monitoring component 4. The output end of the monitoring data output unit is connected to the exploration control end. Through the setting of the geological migration monitoring system, the monitoring process of the deep monitor 10 can be automatically controlled. At the same time, the multi-resistance monitoring of the deep monitor 10 can be intelligently controlled using the pressure data sensed by the deep monitor 10. This effectively improves the monitoring accuracy of the deep monitor 10, promotes the intelligence and automation of the deep monitor 10, and enhances the effectiveness and utility of deep geological exploration. Furthermore, the deep monitor 10 mainly achieves autonomous control and autonomous monitoring through the cooperation of the borehole obstruction component 3 and the migration monitoring component 4. It can adjust the appropriate pressure-sensing resistance data according to different strata conditions, which facilitates the control of the monitoring response sensitivity, realizes the data acquisition of small geological migrations, and improves the data accuracy of exploration.

[0060] Figure 2-9 The outer end of the monitoring tube 1 is shown to have multiple shielding grooves 11 and a movement sensing hole 12 connected to and located on the upper side of the shielding grooves 11. The inlet shielding assembly 3 includes two traction elastic tubes 32 fixedly installed on the lower inner wall of the shielding grooves 11. The upper ends of the two traction elastic tubes 32 are fixedly connected to arc-shaped shielding plates 31, and the arc-shaped shielding plates 31 are in sliding fit with the shielding grooves 11 and the movement sensing hole 12. The monitoring outer tube 1 is embedded with a drive tube group 33 that connects to the multiple traction elastic tubes 32. The arc-shaped shielding plates 31 are used to block the movement of the movement sensing hole 12. The installation of the traction elastic tube 32 can protect the migration monitoring component 4 when the deep monitor 10 enters the borehole, reduce the mechanical wear of the migration monitoring component 4, effectively ensure the service life of the migration monitoring component 4, ensure the monitoring accuracy of the migration monitoring component 4, reduce monitoring errors, and also fully ensure the sealing of the deep monitor 10 during non-monitoring periods, preventing deep geological materials from entering the deep monitor 10 and causing damage to the deep monitor 10, thus fully ensuring the effectiveness of the deep monitor 10.

[0061] Figure 2-9The shielding groove 11 has an isolation membrane 34 fixedly connected to the inner wall below, located outside the traction elastic tube 32. The upper end of the isolation membrane 34 is fixedly connected to the traction elastic tube 32. A guide strip is fixedly connected to the outer end of the traction elastic tube 32. The inner wall of the shielding groove 11 has a guide groove that cooperates with the guide strip. The isolation membrane 34 can achieve linkage with the traction elastic tube 32, further improving the sealing and shielding effect of the arc-shaped shielding plate 31 and the isolation membrane 34 on the shielding groove 11 and the movement sensing hole 12 on the monitoring outer tube 1. This effectively ensures the service life of the monitoring outer tube 1, reduces its damage rate, and also protects the drive tube assembly 33, ensuring the stability of the inlet shielding assembly 3. The cooperation of the guide groove and guide strip can effectively limit and guide the deformation of the traction elastic tube 32, thereby ensuring the effective sliding of the arc-shaped shielding plate 31 in the shielding slide groove 11 and the movement sensing hole 12, ensuring the smoothness of control and the accuracy of movement during shielding and release, reducing the time of pre-exploration preparation, and promoting the efficiency of deep geological exploration.

[0062] Figure 2-9 The diagram shows that the formation monitoring core 2 has multiple migration monitoring slots 21 corresponding to the migration sensing holes 12. The migration monitoring component 4 includes a positioning transmission block 43 fixedly connected to the inner wall of the migration monitoring slot 21. An elastic sensing sleeve 42 is fixedly connected to the outer end of the positioning transmission block 43 and communicates with it. An arc-shaped elastic plate 41 is fixedly connected to the outer end of the elastic sensing sleeve 42, and both the elastic sensing sleeve 42 and the arc-shaped elastic plate 41 slide in cooperation with the migration monitoring slot 21. The formation monitoring core 2 is embedded with a sensing resistance control tube group 44 that communicates with multiple positioning transmission blocks 43. Through the cooperation of the arc-shaped elastic plate 41 and the elastic sensing sleeve 42, the data sensing of formation displacement is effectively realized. Furthermore, through the sensing resistance control tube group 44, the hydraulic pressure change in the elastic sensing sleeve 42 is controlled by the positioning transmission block 43, which effectively improves the multiple monitoring functions of the arc-shaped elastic plate 41 and the elastic sensing sleeve 42 for geological migration data, realizes comprehensive monitoring of geological migration data, and thus effectively promotes the accuracy of exploration.

[0063] Figure 8 and Figure 9 The elastic sensing sleeve 42 has four hinged elastic sleeve rods 421 at its four corners. A pressure sensor connected to the signal transmission cable 5 is fixedly installed inside the elastic sensing sleeve 42. The input end of the multi-resistance migration acquisition unit is connected to the pressure sensor signal, and the input end of the migration monitoring resistance control unit is also connected to the pressure sensor signal. By observing the changes in the pressure sensor data, it is possible to monitor and control multiple resistances, and also to determine the data and direction of geological migration based on the subsequent changes in pressure sensing data. This facilitates the exploration personnel to invert the acquired data and determine the condition of the deep geology.

[0064] Figure 1-9The upper ends of the drive tube assembly 33 and the sensing resistance control tube assembly 44 extend to the outside of the monitoring outer tube 1 and the formation monitoring core 2, respectively, and are fixedly connected to a check valve and a liquid drive assembly. The output ends of the blocking control unit and the movement monitoring resistance control unit are both connected to the check valve and the liquid drive assembly. The liquid drive assembly includes, but is not limited to, a pump, a liquid storage tank, and a filter. The check valve controls the stop-flow function of the drive tube assembly 33 or the sensing resistance control tube assembly 44, and the pump controls the operation of the drive tube assembly 33 or the sensing resistance control tube assembly 44. The liquid transport and output function of 44 enables the control of the drive tube assembly 33 and the sensing resistance control tube assembly 44. The stop valve and the liquid drive assembly are set on the ground together with the exploration controller 6 and the exploration control terminal. Through the setting of the stop valve and the liquid drive assembly, the comprehensive control of the borehole shielding component 3 and the movement monitoring component 4 can be effectively realized. By using the hydraulic method, the manufacturing cost and manufacturing difficulty of the deep monitor 10 can be reduced, and the control accuracy and portability can also be improved, which can effectively promote the application of the deep monitor 10 in geological exploration work.

[0065] Figure 1-9 The diagram shows that before conducting deep geological exploration using the deep monitoring device 10, exploration technicians input parameters such as the geological conditions of the exploration area, relevant environmental data, and stratigraphic monitoring data control parameters into the basic parameter unit through the exploration control terminal. Then, the basic parameter unit transmits the data to the monitoring processing unit, which facilitates subsequent adjustment of the monitoring resistance. When the deep monitoring device 10 is inserted into the borehole from below, the geological migration monitoring system does not receive any instructions, maintaining the contraction of the migration monitoring component 4 and the shielding effect of the borehole shielding component 3, thereby ensuring the sealing of the deep monitoring device 10 during the insertion process.

[0066] After the deep monitoring device 10 enters the hole, the surveyor sends a monitoring command to the command receiving unit through the survey control terminal. The command receiving unit transmits the monitoring command to the monitoring processing unit, which first sends a command to the shielding control unit to release the shield. The shielding control unit controls the check valve of the drive tube group 33 to open, the weapon control fluid drive group is started, and the liquid medium in the drive tube group 33 and the traction elastic tube 32 is extracted, causing the traction elastic tube 32 to continuously contract and drive the arc-shaped shield 31 to move downward, exposing the movement sensing hole 12 and releasing the shielding effect. After the arc-shaped shield 31 has moved, the shielding control unit controls the check valve to close, keeping the traction elastic tube 32 in a contracted state, and then shuts down the fluid drive group.

[0067] Then, the monitoring and processing unit controls the movement monitoring resistance control unit to start, sending it a pre-monitoring instruction. This causes the movement monitoring resistance control unit to first open the check valve on the sensing resistance control pipe group 44, and then start the hydraulic drive group. The hydraulic drive group delivers liquid medium into the elastic sensing sleeve 42 through the sensing resistance control pipe group 44 and the positioning transmission block 43. The pressure sensor feeds back pressure change data to the movement monitoring resistance control unit, prompting the movement monitoring resistance control unit to judge the pressure data in the multiple elastic sensing sleeves 42 at this time. After reaching the pre-monitored hydraulic strength, the check valve on the sensing resistance control pipe group 44 and the hydraulic drive group are closed to maintain the pressure state of the elastic sensing sleeve 42 at this time. When liquid medium is input into the elastic sensing sleeve 42, the elastic sensing sleeve 42 undergoes elongation deformation under the guidance of the elastic sleeve rod 421, which in turn drives the arc-shaped elastic plate 41 to move towards the monitoring outer pipe 1 and through the movement sensing hole 12 to contact the geological layer.

[0068] Then, when the geological layer moves (whether by releasing contact margin or by squeezing the contact), the arc-shaped elastic plate 41 can transmit the geological layer movement data into the elastic sensing sleeve 42 by maintaining continuous contact with the geological layer, so that the pressure sensor can sense the change in pressure data, and then transmit the data to the multi-resistance movement acquisition unit, so that the multi-resistance movement acquisition unit can process the data and transmit it to the monitoring and processing unit. The monitoring and processing unit first stores the geological layer movement data sensed by the pre-monitoring action, and then adjusts and calculates the subsequent strong resistance monitoring action and weak resistance monitoring action based on this data and exploration parameters.

[0069] The monitoring and processing unit transmits the strong resistance monitoring data to the motion monitoring resistance control unit. Upon receiving the strong resistance monitoring data, the motion monitoring resistance control unit first opens the check valve located on the sensing resistance control pipe assembly 44, then activates the hydraulic drive assembly. This hydraulic drive assembly, through the sensing resistance control pipe assembly 44 and the positioning transmission block 43, delivers liquid medium into the elastic sensing sleeve 42, further increasing the hydraulic pressure within the elastic sensing sleeve 42. The pressure sensor then feeds back the pressure change data to the motion monitoring resistance control unit, prompting the unit to determine the pressure data within the multiple elastic sensing sleeves 42 at that moment. After the hydraulic strength of the strong resistance monitoring is reached, the stop valve and hydraulic drive group on the sensing resistance control pipe group 44 are closed to maintain the pressure state of the elastic sensing sleeve 42 at this time. This promotes the contact force between the elastic sensing sleeve 42 supporting the arc-shaped elastic plate 41 and the geological layer. As a result, when the geological layer undergoes slight movement, the pressure sensor inside the elastic sensing sleeve 42 can also sense the pressure change data and then transmit the data to the multi-resistance movement acquisition unit. The multi-resistance movement acquisition unit processes the data and transmits it to the monitoring and processing unit. The monitoring and processing unit first stores the geological layer movement data sensed by the strong resistance detection.

[0070] The monitoring and processing unit transmits the weak resistance monitoring data to the motion monitoring resistance control unit. Upon receiving the weak resistance monitoring data, the motion monitoring resistance control unit first opens the check valve located on the sensing resistance control pipe assembly 44, then activates the hydraulic drive assembly. This allows the hydraulic drive assembly to draw liquid medium from the elastic sensing sleeve 42 through the sensing resistance control pipe assembly 44 and the positioning transmission block 43, reducing the hydraulic pressure within the elastic sensing sleeve 42. The pressure sensor then feeds back the pressure change data to the motion monitoring resistance control unit, prompting the unit to determine the pressure data within the multiple elastic sensing sleeves 42 at that moment, and to determine the hydraulic pressure required for weak resistance monitoring. Then, the stop valve and hydraulic drive group on the sensing resistance control pipe group 44 are closed to maintain the pressure state of the elastic sensing sleeve 42 at this time, reduce the resistance of the elastic sensing sleeve 42 to the arc-shaped elastic plate 41 to the geological layer, and thus be able to sense the large migration data of the geological layer to a greater extent, reduce the migration resistance error caused by the resistance of the elastic sensing sleeve 42. The pressure sensor inside the elastic sensing sleeve 42 senses the pressure change data and then transmits the data to the multi-resistance migration acquisition unit, so that the multi-resistance migration acquisition unit processes the data and transmits it to the monitoring and processing unit. The monitoring and processing unit first stores the geological layer migration data sensed by the weak resistance detection effect.

[0071] It should be noted that the hydraulic pressure in the elastic sensing sleeve 42 under the weak resistance monitoring control state is less than the hydraulic pressure in the elastic sensing sleeve 42 under the pre-monitoring control state, which is less than the hydraulic pressure in the elastic sensing sleeve 42 under the strong resistance monitoring control state. Furthermore, the hydraulic pressure in the elastic sensing sleeve 42 under the weak resistance monitoring control state is still sufficient to maintain a certain accompanying elongation effect when the geological layer moves away from the side of the arc-shaped elastic plate 41, that is, to keep the elastic sensing sleeve 42 in a pre-compression state.

[0072] After receiving data from pre-monitoring, strong resistance monitoring, and weak resistance monitoring, the monitoring and processing unit sets it into a data feedback group. Then, the data feedback group and related data are transmitted to the exploration control end through the detection data processing unit. This allows exploration personnel to invert and judge deep geological data based on these data. The monitoring and processing unit can then maintain continuous monitoring of deep geology through the above-mentioned monitoring cycle control, continuously outputting data feedback groups, increasing the statistical quantity of monitoring data, and thus improving its comprehensive collection of geological layer migration data. While improving monitoring accuracy, it also effectively promotes the reliability of monitoring data, and enhances the accuracy and effectiveness of geological exploration.

[0073] During long-term geological exploration, without the need for continuous monitoring and waiting by the exploration personnel, the deep monitoring device 10 can wirelessly output or store data while continuously monitoring the geological layers in a multi-resistance manner through the application of wireless signals or data storage. This automated monitoring method reduces the workload of the exploration personnel.

[0074] After completing the exploration work, the exploration personnel send a monitoring completion command to the command receiving unit through the exploration control terminal. The command receiving unit then transmits the command to the monitoring processing unit. Upon receiving the command, the monitoring processing unit first outputs and stores the collected data, and then sends a control command to the transport monitoring resistance control unit. This command first opens the check valve on the sensing resistance control pipe group 44, and then controls the hydraulic drive group to deliver liquid medium into the elastic sensing sleeve 42, further increasing the deformation of the elastic sensing sleeve 42. This causes the arc-shaped elastic plate 41 to push the geological layer away from the monitoring outer pipe 1. Then, the control hydraulic drive group extracts the liquid medium from the elastic sensing sleeve 42, causing the elastic sensing sleeve 42 to contract, and the arc-shaped elastic plate 41 to contract into the transport sensing hole 12. After closing the stop valve and hydraulic drive group on the sensing resistance control tube group 44, the monitoring and processing unit controls the shielding control unit to start, which in turn controls the brake valve on the drive tube group 33 to open, and starts the hydraulic drive group to deliver liquid medium into the drive tube group 33 and the traction elastic tube 32, causing the traction elastic tube 32 to expand, and then drive the arc-shaped shielding plate 31 to move upward, sealing and shielding the movement sensing hole 12. The isolation membrane 34 moves along with the traction elastic tube 32 to shield the shielding slide 11. After shielding is completed, it effectively ensures that the material in the geological layer enters the deep monitor 10 during the process of the deep monitor 10 exiting the hole, ensuring the service life of the deep monitor 10. The exploration personnel control the deep monitor 10 to exit the hole and complete the geological exploration work at this location.

[0075] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
