Description

Technical Field

[0001] The present invention relates to the field of geological exploration, and particularly to a water monitoring well separation device adapted to various geological environments and a monitoring construction method. Background Art

[0002] The publication of CN111622706A discloses a separation and water stop device and method for a transformable strongly sealed single-well double-layer water monitoring well, and the application number of this patent is 2020106536605.

[0003] However, in the actual design and on-site construction of this design, the following outstanding technical problems that cannot be solved by this patent are also found:

[0004] The exposed well wall of the monitoring well for construction monitoring is not complete and smooth. Therefore, after the rubber is filled with water, it does not fit completely with the well wall, and the sealing effect is affected by the well wall conditions. When concrete grouting is carried out, there is an unreliable sealing situation. The main reason is that people simply cannot predict the well wall environment underground;

[0005] Even if the existing technology divides the formation into upper and lower parts, when measuring, the pipeline in the middle is connected to the lower aquifer. When the water pressure in the lower aquifer is relatively high, the water in the lower aquifer will flow out along the monitoring pipe, and even blowout may occur; due to the relatively large depth of the geological well (the depth of the monitoring well in the eastern region is generally more than 500m), the existing sensor cable will undergo plastic deformation under its own weight. When measuring, the actual position of the sensor cannot be determined, and thus the accurate water level cannot be obtained;

[0006] Grouting is carried out underwater. When the grouting pipe cannot be lowered to the top of the separation and water stop device, segregation and stratification phenomena are likely to occur after concrete grouting, and the sealing effect cannot be guaranteed. The most crucial point is that when there are pores due to the incomplete fit between the separation and water stop device and the well wall, the injected concrete will enter the monitoring space of the lower aquifer along the pores in the well wall, blocking the pores of the aquifer and interfering with the hydrogeological monitoring environment.

[0007] Affected by factors such as formation dip angle, uneven formation hardness, and drilling technology, most monitoring wells will have a certain curvature. When the curvature is relatively large, the separator cannot be lowered to the designed installation position;

[0008] When concrete grouting is carried out, it will accumulate near the grouting pipe, and there is an uneven distribution situation. After a long time, the upper and lower two-layer hydrogeological parts will be permeable.

[0009] This patent is improved based on 2020106536605. For the parts not described in this patent, refer to this patent, and the relevant designs of this patent can also be incorporated into this text. Summary of the Invention

The defect of the existing technology targeted is that "the wellbore wall of the monitoring well is sometimes not smooth, so rubber water filling cannot complete the sealing, resulting in a situation where the concrete grouting has been insecurely sealed. The main reason is that people simply cannot predict the wellbore environment underground."; For example, refer to the comparison of the Figures 1 - 5 existing technology shown, assuming that there are necking or cave-ins in some parts of the wellbore, Figures 1 - 5The technology shown will allow for the possibility of local leakage, because the sealing of the overall structure relies on a single rubber material, but this patent uses multiple rubber materials 4 from top to bottom to form multiple sealing points from top to bottom, and even if there is a local failure, it will not cause sealing failure.

[0104] Embodiment Twelve: As a further improvable solution, a parallel solution, or an alternative independent solution, a hydrological monitoring well separation device capable of quickly solidifying concrete underground includes an internal part for separation that can be placed in a geological exploration well. The internal part includes an expandable clamping part, and the expandable clamping part includes an expandable rubber outer skin. It is characterized in that a disc-shaped steel plate structure 202 is fixedly connected to the steel pipe protruding from the internal part. The disc-shaped steel plate structure 202 has two layers, and a closed rubber material 203 is heat-sealed at the edges of the two layers of the disc-shaped steel plate structure 202. An independent water injection port 205 is introduced into the space between the two layers of the disc-shaped steel plate structure 202. The independent water injection port 205 is connected to a central independent water filling pipe 201, and the central independent water filling pipe 201 passes through the central pipe 2. The substantial technical effect achieved by the technical solution here and its implementation process, that is, the basic function, are as follows: After the closure is completed and before grouting, the central independent water filling pipe 201 is filled with water, and the water is injected between the two layers of the disc-shaped steel plate structure 202 through the independent water injection port 205. The closed rubber material 203 presses against the well wall. At this time, the multi-purpose grouting pipe 204 pumps water between the disc-shaped steel plate structure 202 and the closed point, providing space and a relatively dry cement solidification environment for concrete grouting or reducing the influence of water on concrete solidification;

[0105] Subsequently, concrete is injected through the multi-purpose grouting pipe 204; after the injection is completed, water is pumped out from the central independent water filling pipe 201 to make the closed rubber material 203 retract.

[0106] The targeted defect is that "during the grouting process, since the lower layer has been closed, but there is still water in the upper layer. After the concrete is grouted, if there is exactly water in the closed bottom layer, then the concrete will be diluted by the water, resulting in a limited closing effect. The most crucial thing is that the concrete has not solidified and is mixed in the water, which will affect the hydrological measurement of the upper layer and cause inaccurate measurement results;".

[0107] Embodiment Thirteen: As a further improvable solution, a parallel solution, or an alternative independent solution, it further includes a multi-purpose grouting pipe 204. The multi-purpose grouting pipe 204 passes through the two layers of the disc-shaped steel plate structure 202; a sealing ring is arranged at the position where the multi-purpose grouting pipe 204 passes through the hole of the steel plate structure 202. The substantial technical effect achieved by the technical solution here and its implementation process, that is, the basic function, are as follows: The multi-purpose grouting pipe 204 can first pump water and then grout, so that the solidification of the concrete is not affected by the complex underground environment, especially the hydrological environment.

[0108] Example 14: As a further improvable solution, a parallel solution, or an alternative independent solution, a grouting space is included between the lower surface of the disc-shaped steel plate structure 202 and the expandable clamping part. The substantial technical effects achieved by the technical solution herein and the implementation process, i.e., the basic functions, are as follows: This design actually constructs a relatively independent grouting space underground to minimize the influence of water on the setting of concrete.

[0109] Example 15: As a further improvable solution, a parallel solution, or an alternative independent solution, a multi-purpose grouting pipe 204 is connected to a water pump and a concrete supply structure through a tee above. The substantial technical effects achieved by the technical solution herein and the implementation process, i.e., the basic functions, are as follows: The inconsistent connections of the tee here achieve different functions, such as pumping water or grouting.

[0110] Example 16: As a further improvable solution, a parallel solution, or an alternative independent solution, the disc-shaped steel plate structure 202 and the steel pipe protruding from the built-in part are integrally manufactured. The substantial technical effects achieved by the technical solution herein and the implementation process, i.e., the basic functions, are as follows: In addition to integral manufacturing, welding can also be used.

[0111] Example 17: As a further improvable solution, a parallel solution, or an alternative independent solution, the multi-purpose grouting pipe 204 is a steel pipe.

[0112] Solution 4: Refer to Figure 17 、 Figure 18 、 Figure 19 ;

[0113] Example 18: As a further improvable solution, a parallel solution, or an alternative independent solution, a hydrographic monitoring separation device adapted to a wellbore with a large curvature. The separation device includes a middle pipe 2, and is characterized in that the middle pipe is separated into more than one section by a steerable separation part. The steerable separation part includes a flexible hose 301 in the middle, and more than one chain 302 is included around the flexible hose 301; the more than one chain 302 connects the middle pipes at both ends, and the flexible hose 301 in the middle is heat-sealed to the middle pipes at both ends;

[0114] When in the well, the flexible hose 301 can turn, and the more than one chain 302 can also turn and the chain has sufficient strength to prevent the flexible hose from being pulled apart. The substantial technical effects achieved by the technical solution herein and the implementation process, i.e., the basic functions, are as follows: During the lowering and installation process, the flexible hose 301 can turn, and the more than one chain 302 can also turn and the chain has sufficient strength to prevent the flexible hose from being pulled apart; it can adapt to the situation where some well sections of the monitoring well have a large curvature.

[0115] The defect of the existing technology targeted is that "when the monitoring well is completed, it is not completely vertical, there is a certain inclination and bending. Because the well depth is relatively large, the current well completion technology cannot achieve complete verticality, so the separator cannot be smoothly placed and installed at the designed horizon."

[0116] Example XIX: As a further improvable solution, parallel solution or alternative independent solution, the hose 301 is a corrugated pipe. The substantial technical effect achieved by the technical solution here and its implementation process, that is, the basic function, are as follows: Substantially, as long as the strength is sufficient and it can turn, any material can be used.

[0117] Example XX: As a further improvable solution, parallel solution or alternative independent solution, both the upper and lower sides of the chain 302 are welded or fixed to the middle pipe by screws. The substantial technical effect achieved by the technical solution here and its implementation process, that is, the basic function, are as follows: This embodiment provides a specific fixing structure, and similar fixing structures are within the protection scope of this patent.

[0118] Solution Five: Refer to Figure 20 、 Figure 21 、 Figure 22 ;

[0119] Example XXI: As a further improvable solution, parallel solution or alternative independent solution, a separating device that can reduce the impact of concrete on the hydrogeological environment, includes an internal part for separation that can be placed in a geological exploration well. The internal part includes an expandable clamping part and also includes a grouting pipe. It is characterized in that a slurry distribution plate 401 is included below the grouting pipe, and a plurality of slurry distribution ports 402 are included below the slurry distribution plate 401. The grouting pipe communicates with the middle space of the slurry distribution plate 401.

Therefore, the concrete can evenly fill the space to be sealed.

[0120] The targeted defect is that "when grouting concrete, it will accumulate at the grouting pipe orifice, the distribution is uneven, and after a long time, the upper and lower hydrogeological parts will be permeable."

[0121] Example XXII: As a further improvable solution, parallel solution or alternative independent solution, the slurry distribution plate 401 is square or circular, and it has a notch for passing through the middle pipe 2. The substantial technical effect achieved by the technical solution here and its implementation process, that is, the basic function, are as follows: This design can avoid the position conflict between the slurry distribution plate and the central pipe.

[0122] Embodiment Twenty-Three: As a further improvable solution, a parallel solution, or an alternative independent solution, the bottom wall of the slurry dividing tray 401 is an inclined wall. The substantial technical effect achieved by the technical solution herein and its implementation process, i.e., the basic function, are as follows: The inclined wall facilitates the self-flow of concrete.

[0123] Embodiment Twenty-Four: As a further improvable solution, a parallel solution, or an alternative independent solution, the slurry dividing ports 402 are equally spaced. The substantial technical effect achieved by the technical solution herein and its implementation process, i.e., the basic function, are as follows: To make the concrete distribution as uniform as possible and the layering distinct. The concrete can evenly fill the space to be enclosed.

[0124] Innovatively, each of the above effects exists independently, and the combination of the above results can also be achieved with a single set of structures.

[0125] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve the co-realization of multiple effects.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the claimed protection.
