Description

Technical Field

[0001] The utility model relates to the technical field of collapse monitoring, in particular to a brine mining well collapse layer monitoring system. Background Art

[0002] The underground brine of salt lakes contains a variety of valuable minerals, such as potassium, sodium, lithium, magnesium, bromine, etc. These minerals can be widely used in fertilizers, glass manufacturing, chlor-alkali industry, food processing and other fields. The brine well is the main way to extract underground brine. By drilling wells, you can reach the brine layer under the salt lake, so as to extract brine for subsequent processing and application.

[0003] The salt lake debris layer (including the sand layer) is a kind of clay soil containing a large amount of soluble salt in a soft plastic to fluid plastic state. It is a kind of salt lake soft soil layer, and its rock types are mainly salt-containing fine sand, silt, and soft clay soil. When the aquifers of the underground brine in the salt lake include the salt lake debris layer, during the brine mining process, the dynamic water pressure difference can easily cause the salt lake groundwater to seep in large quantities in the saline soil. The seepage and scouring of water cause the fine sand layer and the silt layer to continuously flow back to the well body, causing the soil structure of the soft soil layer in the well to become unstable and deformed, resulting in the collapse of the wellhead of the brine mining well and the cavity of the well wall. In severe cases, it can also lead to the overall collapse and scrapping of the brine mining well.

[0004] At present, gravel filling and cavity filling are mainly used to prevent the overall collapse of brine wells. However, after gravel filling and cavity filling, gravel is prone to "bridge" between the hole wall and the well pipe. At the same time, brine salt formation will also consolidate the gravel layer. The above two situations will cause the gravel to be unable to sink to support and fill the cavity of the well wall. The current method of bridging consolidation is mainly manual dredging. However, manual dredging has problems such as untimely dredging, low dredging efficiency and high labor cost. Utility Model Content

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figure 1 As shown in the figure, the groundwater of Bieletan Salt Lake is generally divided into four aquifers. The brine is mainly found between the crystals of rock salt and the pores of the sand layer. There are clastic layers between the aquifers. The clastic layer (including the sand layer) of Bieletan Salt Lake is a kind of clay soil containing a large amount of soluble salt in a soft plastic to fluid plastic state. It belongs to a kind of soft soil layer of salt lake. The rock types are mainly salt-containing fine sand, silt, and soft clay. During the brine mining process, the dynamic water pressure difference causes a large amount of groundwater to seep through the saline soil. The seepage and scouring of the water cause the fine sand layer and silt layer to continuously flow back into the well body, causing the soft soil layer to become unstable and deformed, resulting in the collapse of the wellhead of the brine mining well and the cavity of the well wall. In severe cases, it leads to the overall collapse of the brine mining well and the scrapping of the well.

[0027] like Figures 2 to 4 As shown, according to an embodiment of the utility model, the brine well collapse stratification monitoring system includes a brine well 1 and a relief device 6, the brine well 1 includes a water filter pipe 2 and a well wall 3, the water filter pipe 2 is arranged in the center of the brine well 1, the relief device 6 includes a drilling tool 602 and a driving device 7, the drilling tool 602 is arranged in the annular gap between the water filter pipe 2 and the well wall 3, and the driving device 7 is drivingly connected to the drilling tool 602.

[0028] In the above technical scheme, the filter pipe 2 filters the underground brine of the salt lake, and filters out the particulate impurities such as sand, gravel and broken rocks contained in the underground brine; the deburring device 6 is mainly used to deburre the gravel that has formed a bridging consolidation phenomenon after the gravel filling cavity is filled, and the deburring device 6 includes a drilling tool 602 and a driving device 7, wherein the drilling tool 602 is arranged in the annular gap between the filter pipe 2 and the well wall 3, and the drilling tool 602 vibrates or rotates under the drive of the driving device 7, and the vibration or rotation of the drilling tool 602 is used to deburr the bridging and consolidated gravel, so that the gravel sinks to support and fill the cavity of the well wall, thereby timely eliminating or reducing the risk of overall collapse of the brine mining well.

[0029] like Figure 4 As shown, in one embodiment, the drilling tool 602 includes a drill rod connection portion, which includes a drill rod 606 and a drill rod joint 604 , and a plurality of drill rods 606 are fixedly connected via the drill rod joint 604 .

[0030] In the above technical solution, the drilling tool 602 includes a drill rod connection portion, which includes a drill rod 606 and a drill rod joint 604, wherein the drill rod 606 is mainly used to transmit the vibration or rotation generated by the driving device 7 driving the drill rod 606 to the well, so as to achieve the effect of loosening the bridge-consolidated gravel, and the drill rod joint 604 is used to connect multiple drill rods 606 together, so as to achieve the loosening of bridge-consolidated gravel at different depths.

[0031] In one embodiment, the drilling tool 602 is an internally squeezed branch plate drilling tool.

[0032] like Figure 2 and 4 As shown, in one embodiment, the drilling tool 602 includes a drill rod connection part and a drill bit 603, the driving device 7 is drivingly connected to a first end of the drill rod connection part, and the drill bit 603 is connected to a second end of the drill rod connection part.

[0033] In the above technical solution, the driving device 7 drives the drill rod connection part to rotate, and the drill rod connection part drives the drill bit 603 to rotate, so as to break and disperse the bridged and consolidated gravel.

[0034] like Figure 2 and 4 As shown, in one embodiment, the deburring device 6 further includes an outer hollow tube 601, a check valve is installed at the bottom of the outer hollow tube 601, and the outer hollow tube 601 is sleeved on the drill pipe connection part.

[0035] In the above technical solution, the outer hollow tube 601 is sleeved on the drill rod connection to protect the drill rod connection and prevent the filling gravel 4 around the drill rod connection from directly contacting the drill rod connection and squeezing the drill rod connection to cause damage and breakage of the drill rod connection. A check valve is installed at the bottom of the outer hollow tube 601 to prevent gravel or fluid outside the outer hollow tube 601 from entering the outer hollow tube 601 from the bottom of the outer hollow tube 601 and damaging the drill rod connection. Figure 4 As shown, in one embodiment, a jet hole 605 is provided on the side of the drill bit 603 facing the driving device 7, a fluid transmission channel is provided in the drill rod connecting portion, and the jet hole 605 is connected to the fluid transmission channel.

[0036] In the above technical solution, a rotary jet hole 605 is provided on the side of the drill bit 603 facing the driving device 7, and the fluid transmission channel is used to transport fluid to the rotary jet hole 605. After the drill bit 603 performs rotary crushing on the bridged and consolidated gravel, the rotary jet hole 605 sprays fluid in the direction of the driving device 7, so that the debonded gravel flows with the fluid in the direction of the driving device 7, thereby increasing the fluidity of the gravel and causing the gravel to flow into the cavity of the well wall, thereby improving the effect of gravel filling the cavity 301 of the well wall. The side of the drill bit 603 facing the driving device 7 is mainly gravel that has been crushed by the drill bit 603. There is a large gap between the crushed gravel and the drill bit 603, which will not block the rotary spray hole 605 and hinder the fluid from spraying out. If the rotary spray hole 605 is set on the side of the drill bit 603, on the one hand, when the drill bit 603 is rotating and crushing, the gravel will stick to the side wall of the drill bit 603, which will block the rotary spray hole 605 and hinder the fluid from spraying out. On the other hand, the gravel cannot flow into the well wall cavity 301 with the fluid. Therefore, setting the rotary spray hole 605 on the side of the drill bit 603 cannot increase the fluidity of the gravel very well, and cannot improve the effect of the gravel filling the well wall cavity 301.

[0037] In one embodiment, the fluid transmitted in the fluid transmission channel may be a liquid such as water, or a gas such as clean air.

[0038] like Figure 3 As shown, in one embodiment, the brine well collapse layer monitoring system also includes a terminal control component 8, and the terminal control component 8 includes an RTU9 (Remote Terminal Unit), and the RTU9 is electrically connected to the relief device 6.

[0039] In the above technical solution, the terminal control component 8 includes RTU9, and RTU9 is mainly used to control the start and stop of the decongestion device 6.

[0040] In one embodiment, the RTU 9 can control the start and stop of the deburring device 6 in real time, or set the start and stop at preset time intervals.

[0041] like Figure 3 As shown, in one embodiment, the terminal control component 8 further includes a communication relay 803 and an intermediate relay, the communication relay 803 is electrically connected to the RTU9, and the intermediate relay is electrically connected to the communication relay 803 and the decongestion device 6.

[0042] In the above technical scheme, the terminal control component 8 also includes a communication relay 803 and an intermediate relay, wherein the communication relay 803 is mainly used to realize signal transmission and equipment control, and the intermediate relay serves as the power switch of the decontamination device 6 to control the start and stop of the decontamination device 6. When working, the RTU9 sends a signal to the terminal control component 8 to start or shut down the decontamination device 6. The communication relay 803 of the terminal control component 8 receives the signal to start or shut down the decontamination device 6, and controls the intermediate relay to close or open to power on or off the decontamination device 6, thereby starting or shutting down the decontamination device 6.

[0043] In one embodiment, the communication relay 803 is a RS485 type relay.

[0044] In one embodiment, the terminal control component 8 also includes a PLC control cabinet, which has overload, short circuit, and phase loss protection functions. The PLC control cabinet can realize switching of various control modes of the decontamination device 6, such as manual control, automatic control, and remote control.

[0045] like Figure 3 As shown, in one embodiment, the brine well collapse stratification monitoring system also includes a remote monitoring system, and the remote monitoring system includes a stratification settlement monitor 5, and the stratification settlement monitor 5 is electrically connected to the RTU9.

[0046] In the above technical solution, the stratified settlement monitor 5 collects soil settlement displacement data and transmits the data to RTU9, which records and transmits the data, thereby realizing remote monitoring of soil settlement conditions at the brine mining well site. In addition, RTU9 is also used to control the start and stop of the stratified settlement monitor 5.

[0047] In one embodiment, the stratified settlement monitor 5 can select a variety of measurement modes such as timed measurement, real-time measurement, and follow-up measurement.

[0048] like Figure 2 As shown, in one embodiment, the stratified settlement monitor 5 includes a settlement tube 501, a magnetic ring 502, a magnetic induction probe, an inductance detection device and a scale. The settlement tube 501 is buried in the filling soil layer 503. Multiple magnetic rings 502 are arranged at intervals and movably mounted outside the settlement tube 501. The magnetic induction probe is connected to one end of the zero scale of the scale and can move along the settlement tube 501.

[0049] In one embodiment, the stratified settlement monitor 5 also includes a positioning ring 504, which is fixedly mounted on the settlement tube 501. A positioning ring 504 is arranged at the lower part of a soil layer. The positioning ring 504 limits the measuring range of the magnetic ring 502 arranged in the soil layer to the soil layer, and prevents the magnetic ring 502 from moving to other soil layers, thereby ensuring that the magnetic ring 502 only monitors the settlement of the soil layer in which it is located. By arranging a positioning ring 504 at the lower part of each soil layer, the problem of multiple magnetic rings 502 moving to the same soil layer, resulting in the inability to realize stratified monitoring of the settlement of different soil layers, is avoided.

[0050] In one embodiment, the material of the sedimentation tube 501 is flexible plastic.

[0051] In the above technical scheme, a deep hole penetrating through each soil layer is drilled on the ground to set up a stratified settlement monitor 5, a settlement pipe 501 is placed in the center of the deep hole, and a filling soil layer 503 of a certain thickness is filled in the gap between the settlement pipe 501 and the hole wall. The settlement pipe 501 can block the filling soil layer 503 and provide a passage for the magnetic induction probe to enter the underground. Then a magnetic ring 502 is arranged on the outer surface of the settlement pipe 501, and then a filling soil layer 503 of a certain thickness is continuously filled, so that a magnetic ring 502 is arranged on the outside of the settlement pipe 501 at a certain distance. When the stratum settles, the magnetic ring 502 in the stratum is driven to sink synchronously, and the magnetic induction probe is connected to one end of the zero scale of the ruler, and the magnetic induction probe is slowly lowered along the settlement pipe 501. The induction probe will sense the change of magnetic field and generate an electrical signal. The inductance detection device connected to the magnetic induction probe determines that the magnetic ring 502 is sensed according to the electrical signal sent by the magnetic induction probe. At this time, according to the scale of the ruler at the mouth of the settlement tube 501, the distance between the position of the magnetic ring 502 and the mouth of the settlement tube 501 can be determined, thereby completing a single soil layer depth data measurement; when the stratum settles, the magnetic ring 502 is driven to sink synchronously, and the steps of slowly lowering the magnetic induction probe, sensing the magnetic ring 502, and recording the scale of the ruler are repeated to complete multiple soil layer depth data measurements. The data difference between two adjacent measurements in the multiple measurements is the soil layer settlement. By comparing the changes in the positions of each magnetic ring over time, the deformation rate of each stratum can also be obtained.

[0052] like Figure 3 As shown, in one embodiment, the remote monitoring system also includes a data transmission terminal 10 and a monitoring center computer server 11. The monitoring center computer server 11 is connected to communicate with the RTU9 through the data transmission terminal 10, and the RTU9 is electrically connected to the communication relay 803.

[0053] In the above technical solution, the data transmission terminal 10 transmits the field data collected by RTU9 via the communication relay 803 to the monitoring center computer server 11. The monitoring center computer server 11 can further save and process the data, and can also remotely send control instructions to RTU9 through the data transmission terminal 10, and realize remote control of the field equipment through RTU9 and the communication relay 803 electrically connected to RTU9.

[0054] In one embodiment, the computer server 11 of the monitoring center has an intelligent early warning control function, which can compare the data of multiple settlement and deformation of each soil layer, analyze the settlement and cavity evolution trends, issue early warnings and autonomously remotely control on-site equipment to carry out relief operations.

[0055] like Figure 3 As shown, in one embodiment, the communication relay 803 is provided with a first channel and a second channel, the intermediate relay includes a first intermediate relay 801 and a second intermediate relay 802, the communication relay 803 is electrically connected to the stratified settlement monitor 5 through the second intermediate relay 802 connected to the first channel, and the communication relay 803 is electrically connected to the decontamination device 6 through the first intermediate relay 801 connected to the second channel.

[0056] In the above technical scheme, the communication relay 803 is provided with a first channel and a second channel, which can realize signal transmission and device control of two devices connected to the first channel and the second channel respectively. The first intermediate relay 801 and the second intermediate relay 802 are respectively used as power switches of the decongestion device 6 and the stratified sedimentation monitor 5, and are used to control the on and off of the decongestion device 6 and the stratified sedimentation monitor 5. Through the cooperation of multiple channels of the communication relay 803 and the corresponding intermediate relays, the effect of one communication relay 803 controlling the switches of multiple terminal devices and transmitting signals of multiple terminal devices is achieved.

[0057] The working process of the brine well collapse layer monitoring system of the utility model is as follows: by setting up a layered settlement monitor 5 to collect the settlement data of each soil layer of the brine well, and transmitting the collected data to the monitoring center computer server 11 through the communication relay 803, RTU9 and the data transmission terminal 10, the monitoring center computer server 11 combines the cloud server data interaction to analyze and warn the cavity situation of the well wall. When the monitoring center computer server 11 finds that the parameters such as the settlement amount, settlement rate, and cavity area exceed or approach the preset safety threshold, the monitoring center computer server 11 transmits the data to the data transmission terminal 10, RTU9 and the communication relay. 803 sends a start command to the relief device 6, and then the driving device 7 starts, driving the drill bit 602 to crush and relieve the bridged and consolidated gravel in the annular gap between the water filter pipe 2 and the well wall 3. At the same time, the rotary spray hole 605 on the drill bit 603 sprays fluid in the direction of the driving device 7, so that the relieved gravel flows with the fluid in the direction of the driving device 7, increasing the fluidity of the gravel and improving the effect of the gravel filling the cavity of the well wall. The computer server 11 of the monitoring center determines that the risk of overall collapse of the brine well is easily eliminated or reduced to a safe range based on parameters such as sedimentation amount, sedimentation rate, and cavity area, and then sends a stop command to the relief device 6.

[0058] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: the brine well collapse stratification monitoring system includes a brine well 1 and a relief device 6, the brine well 1 includes a water filter pipe 2 and a well wall 3, the water filter pipe 2 filters the underground brine of the salt lake, and filters out the particulate impurities such as sand, gravel and broken rocks carried in the underground brine; the relief device 6 is mainly used to relieve the gravel that has bridged and consolidated after the gravel filling cavity, the relief device 6 includes a drilling tool 602 and a driving device 7, wherein the drilling tool 602 is arranged in the annular gap between the water filter pipe 2 and the well wall 3, the drilling tool 602 vibrates or rotates under the drive of the driving device 7, and the gravel that has bridged and consolidated is relieved by the vibration or rotation of the drilling tool 602, so that the gravel sinks to support and fill the well wall cavity 301, thereby timely eliminating or reducing the risk of overall collapse of the brine well. Compared with the current manual dredging method mainly used for dredging and bridging consolidation, the brine well collapse stratification monitoring system proposed in the utility model, by setting a dredging device 6 to dredge the bridge-consolidated gravel, so that the gravel sinks to support and fill the well wall cavity 301, overcomes the defects of untimely dredging, low dredging efficiency and high labor cost during manual dredging of gravel bridge consolidation, and achieves the effect of timely eliminating or reducing the overall collapse risk of the brine well.
