Description

Technical Field

[0001] The present invention relates to the technical field of mine exploration, and in particular to a fine detection method for salt mine solution cavities based on three-dimensional seismic and sonar detection technologies. Background Art

[0002] Solution mining is the main mining method for salt mines at present. During the mining process, a large number of solution cavities are formed in the salt ore layer. The development of the solution cavities and the degree of damage to the roof of the salt layer are of great significance for salt mine mining. Finding out the spatial form of the solution cavities formed during salt mine mining and the degree of damage to the roof plays an important role in reducing surface subsidence in the salt mine mining area and subsequent salt mine mining design.

[0003] In the existing technology of salt mine production, the three-dimensional seismic method is used to detect salt mine solution cavities, and remarkable exploration results have been achieved. It can better determine the spatial form of the salt mine solution cavities, the thickness of the solution cavity roof and the integrity of the overlying strata. However, the structure of salt mine solution cavities is complex and changeable. Especially with the progress of mining, the expansion of the solution cavity range and the connection of some solution cavities reduce the resolution of the solution cavities. The sonar method is an important technology for underground karst cave detection, which can directly and accurately determine the spatial form and volume of the solution cavity. This method has the characteristics of simple operation, fast detection speed and high accuracy, but it can only be carried out one by one for each solution cavity during detection, and the detection cost is relatively high.

[0023] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The fine detection method for salt mine solution cavities based on 3D seismic and sonar detection technologies of the present invention will be described below with reference to the accompanying drawings. Figure 1 It is a schematic flow chart of the fine detection method for salt mine solution cavities based on 3D seismic and sonar detection technologies provided by the present invention. As Figure 1 shown, the method includes the following steps 101 to 104.

[0025] Step 101: Construct a 3D geological model of the solution cavity in the salt mine area to be measured according to the solution cavity rock layer parameters of the salt mine area to be measured obtained by 3D seismic exploration.

[0026] In the embodiment of the present invention, 3D seismic exploration is first carried out on the salt mine area to be measured. Referring to the requirements of the preset high-precision 3D seismic exploration, the collected seismic parameters are optimized, and a suitable observation system and 3D pre-stack migration fine imaging technology are adopted to obtain the 3D seismic data volume of the solution cavity in the salt mine area to be measured, as Figure 2 shown.

[0027] Next, the solution cavity rock formation parameters of the salt mining area to be measured can be determined from the 3D seismic data volume of the solution cavity, including the top interface of the salt mine solution cavity, the thickness of the solution cavity roof, the depth of the overlying strata, and the integrity of the bottom layer. Then, using the method of 3D visual geological modeling, a 3D geological model of the solution cavity in the salt mining area to be measured is constructed, and its visualization schematic diagram can be as Figure 3 shown. In this way, information such as the top and bottom plates of the salt mine, the brine extraction solution cavity, and the collapse of the solution cavity in the salt mining area to be measured can be truly presented in a three-dimensional form.

[0028] Step 102: Conduct sonar detection on a preset number of target solution cavities in the salt mining area to be measured to obtain the spatial form and volume of the target solution cavity.

[0029] Next, adopt the sonar detection method to select a preset number of target solution cavities for sonar detection. Considering the high cost of sonar detection, in the embodiments of the present invention, the preset number is less than the total number of solution cavities in the salt mining area to be measured, and the target solution cavity is any one of the solution cavities in the salt mining area to be measured. That is to say, the embodiments of the present invention only conduct sonar detection on some solution cavities in the salt mining area to be measured.

[0030] Although the smaller the preset number of sonar detections, the lower the cost, it is still necessary to reasonably determine the preset number of sonar detections according to the total number of solution cavities in the salt mining area to be measured. Optionally, the preset number can be one-tenth or one-twentieth of the total number of solution cavities in the salt mining area to be measured. That is, when the total number of solution cavities is within 20, the preset number of sonar detections is 1 or 2.

[0031] After detecting the target solution cavity by sonar detection, the detection result can intuitively and accurately determine the spatial form of the solution cavity, as Figure 4 shown. The spatial contour of the solution cavity can be completely displayed in the detection result, and the volume of the solution cavity can be further calculated based on this spatial contour.

[0032] Step 103: Match the spatial form and volume of the target solution cavity with the 3D geological model of the solution cavity.

[0033] Next, use the spatial form and volume of the target solution cavity obtained by sonar detection as quantitative calibration, and then match the spatial form and volume of the target solution cavity with the 3D geological model of the solution cavity to determine whether there are differences between the spatial form and volume of the target solution cavity in the 3D geological model of the solution cavity and the sonar detection results. During the matching process, determine whether the spatial forms are consistent and whether the volumes are the same.

[0034] Step 104: When the matching is successful, determine the spatial form and volume of each solution cavity in the salt mining area to be measured according to the 3D geological model of the solution cavity.

[0035] When the matching is successful, it indicates that the results of the 3D seismic exploration are consistent with those of the sonar detection. Then, the 3D geological model of the solution cavities has accurately represented the specific situations of each solution cavity in the salt mine area to be measured, including the development direction, development status, internal connection status, etc. of the solution cavities. Thus, the spatial morphology and volume of each solution cavity in the salt mine area to be measured can be determined based on the 3D geological model of the solution cavities, achieving the purpose of finely depicting the spatial morphology of the solution cavities.

[0036] The fine detection method for salt mine solution cavities provided by the present invention, based on 3D seismic and sonar detection technologies, while using 3D seismic exploration to perform 3D modeling on the solution cavities in the salt mine area to be measured, combines sonar detection to detect the solution cavities in the salt mine area to be measured, and uses the sonar detection results as quantitative calibration to assist in correcting the 3D modeling of the solution cavities under 3D seismic exploration. The combination of points, surfaces, and solids is conducive to the analysis and interpretation of seismic geological data, and the detection accuracy is higher. And sonar detection only targets some solution cavities in the salt mine area to be measured, without the need to detect each solution cavity one by one, reducing the detection cost.

[0037] In some embodiments, before constructing the 3D geological model of the solution cavities in the salt mine area to be measured, it further includes: Performing 3D seismic exploration on the salt mine area to be measured to obtain 3D seismic data; Adopting 3D prestack migration processing on the 3D seismic data to obtain the spatial imaging of each solution cavity in the salt mine area to be measured; Determining the solution cavity rock layer parameters in the salt mine area to be measured according to the spatial imaging.

[0038] Here, to establish the 3D geological model of the solution cavities, first perform 3D seismic exploration on the salt mine area to be measured to obtain 3D seismic data, and then adopt 3D prestack migration fine imaging processing on the 3D seismic data to obtain the spatial imaging of each solution cavity in the salt mine area to be measured. Seismic 3D prestack migration is a process of reconstructing the 3D seismic data volume. The seismic data processing mainly focuses on 3D prestack migration, supplemented by fine imaging technology, which can more realistically display the underground geological body image.

[0039] Finally, determine the solution cavity rock layer parameters in the salt mine area to be measured according to the seismic 3D data volume as the solution cavity interpretation result of the 3D seismic exploration, specifically including the top interface of the salt mine solution cavity, the thickness of the solution cavity roof and the thickness and integrity of the overlying strata.

[0040] In the embodiments of the present invention, through 3D seismic exploration, the 3D image of the solution cavities in the mining area to be measured can be more realistically displayed, and the obtained solution cavity interpretation result is more convenient for constructing the corresponding 3D geological model of the solution cavities, laying a foundation for subsequent model correction in combination with the sonar detection results.

[0041] In some embodiments, constructing the 3D geological model of the solution cavities in the salt mine area to be measured according to the solution cavity rock layer parameters in the salt mine area to be measured includes: Obtain the geological and production data of the salt mine area to be measured; Based on the geological and production data and the solution cavity rock formation parameters of the salt mine area to be measured, conduct three-dimensional visualization modeling to obtain the three-dimensional geological model of the solution cavity in the salt mine area to be measured.

[0042] When conducting three-dimensional modeling on the salt mine area to be measured, it is still necessary to visualize the geological and production data of the salt mine area to be measured. The geological and production data include the geological data, borehole data, and production well mining data of the salt mine area to be measured.

[0043] Next, based on the geological and production data and the solution cavity rock formation parameters of the salt mine area to be measured, conduct three-dimensional visualization modeling to obtain the three-dimensional geological model of the solution cavity in the salt mine area to be measured. The three-dimensional visualization modeling can be implemented using visualization software such as WebGL, and functions such as zooming and rotating can be added during the visualization process. Through the three-dimensional display of the solution cavity three-dimensional geological model, the distribution and spatial state of each solution cavity in the salt mine area to be measured can be displayed.

[0044] In the embodiment of the present invention, based on three-dimensional seismic exploration, three-dimensional modeling is carried out on the salt mine area to be measured, realizing the description of the distribution and spatial state of the solution cavity, and integrating the geological and production data into the corresponding three-dimensional geological model of the solution cavity, providing guidance for subsequent mining generation work.

[0045] In some embodiments, the detection results obtained by sonar detection can be used to correct the three-dimensional geological model of the solution cavity established by three-dimensional seismic exploration. In essence, it is to correct the spatial shape and volume of each solution cavity in the three-dimensional geological model of the solution cavity to ensure the description accuracy of the solution cavity in the three-dimensional geological model of the solution cavity.

[0046] The following describes the process of matching the spatial shape and volume of the target solution cavity with the three-dimensional geological model of the solution cavity. First, determine the three-dimensional shape and three-dimensional volume of the target solution cavity from the three-dimensional geological model of the solution cavity. The three-dimensional geological model of the solution cavity can clearly display the three-dimensional shape and three-dimensional volume of each target solution cavity. However, since it is modeled uniformly according to the solution cavity rock formation parameters, there are differences from the actual situation.

[0047] Therefore, next, determine the coincidence degree between the three-dimensional shape and the spatial shape of the target solution cavity, and determine the difference value between the three-dimensional volume and the volume of the target solution cavity. The calculation of the coincidence degree can be reflected on the plane level. By comparing the shapes and geometric features of any two planes, the coincidence degree of the two planes can be calculated. For example, a coincidence degree coefficient can be used to measure it. The difference value is directly the absolute value of the volume difference between the two.

[0048] Here, the modeling effect of the three-dimensional geological model of the solution cavity is compared with the effect of sonar detection. The differences in spatial form and volume between the two are reflected by calculating the coincidence degree and the difference value respectively. Of course, the two cannot be strictly similar or identical, and a certain error is allowed. Therefore, in the embodiments of the present invention, corresponding coincidence thresholds and difference thresholds are set according to the allowable error in the actual situation to measure whether the two can be successfully matched.

[0049] When the coincidence degree is less than the preset coincidence threshold and the difference value is less than the preset difference threshold, it indicates that the two are similar in spatial form and volume or the error is within an acceptable range. Then, it can be determined that the spatial form and volume of the target solution cavity match successfully with the three-dimensional geological model of the solution cavity.

[0050] When the coincidence degree is not less than the preset coincidence threshold or the difference value is not less than the preset difference threshold, it indicates that there are large differences in the spatial form or volume between the two. Then, it can be determined that the spatial form and volume of the target solution cavity do not match successfully with the three-dimensional geological model of the solution cavity.

[0051] In the embodiments of the present invention, when matching the spatial form and volume of the target solution cavity with the three-dimensional geological model of the solution cavity, the coincidence degree and the difference value are designed to represent the matching degree between the sonar detection result and the three-dimensional seismic exploration result, so as to control the spatial form and volume of each solution cavity in the three-dimensional geological model of the solution cavity, and effectively detect the modeling error of the three-dimensional seismic exploration result.

[0052] In some embodiments, when matching the spatial form and volume of the target solution cavity with the three-dimensional geological model of the solution cavity, there may also be a situation where the matching fails. At this time, it indicates that there are errors in the spatial form and volume of the solution cavity in the three-dimensional geological model of the solution cavity.

[0053] Therefore, when the matching fails, the embodiments of the present invention perform an iterative process. The iterative process includes: reconstructing the three-dimensional geological model of the solution cavity according to the spatial form and volume of the target solution cavity, and ending the iteration when the reconstructed three-dimensional geological model of the solution cavity matches successfully with the spatial form and volume of the target solution cavity.

[0054] For the schematic diagram of the principle of this iterative process, please refer to Figure 5As shown, on the one hand, after performing three-dimensional seismic exploration on the salt mine area to be measured, the solution cavity interpretation results, that is, the solution cavity rock formation parameters, are obtained, and then a three-dimensional geological model of the solution cavity is constructed by combining geological and production data. On the other hand, after sonar detection of some solution cavities in the salt mine area to be measured, the spatial form and volume of the corresponding target solution cavity are obtained, and then it is determined whether the spatial form and volume of the target solution cavity match the three-dimensional geological model of the solution cavity. If so, that is, if the match is successful, the spatial form and volume of each solution cavity in the salt mine area to be measured can be determined according to the three-dimensional geological model of the solution cavity. If not, that is, if the match fails, an iterative process is executed, and the solution cavity interpretation results are updated according to the spatial form and volume of the target solution cavity, and the three-dimensional geological model of the solution cavity is reconstructed until the match is achieved and the iteration ends.

[0055] In the embodiment of the present invention, after the sonar detection result fails to match the three-dimensional seismic exploration result, by executing an iterative process, the sonar detection result is used to reconstruct the three-dimensional geological model of the solution cavity. Thus, the three-dimensional geological model of the solution cavity is continuously corrected during the iterative process, so that the three-dimensional geological model of the solution cavity can more accurately depict the spatial form and volume of the solution cavity in the salt mine area to be measured.

[0056] Further, as Figure 5 shown, when the match fails, an iterative process is executed to reconstruct the three-dimensional geological model of the solution cavity according to the sonar detection result. Specifically, during the iterative process, the solution cavity rock formation parameters of the salt mine area to be measured are corrected according to the spatial form and volume of the target solution cavity. Because if the spatial form and volume of the solution cavity are inaccurate, then parameters such as the top interface of the salt mine solution cavity, the thickness of the solution cavity roof and the overlying strata will also be inaccurate. Therefore, according to the spatial form and volume of the target solution cavity included in the sonar detection result, the parameters such as the top interface of the salt mine solution cavity, the thickness of the solution cavity roof and the overlying strata are readjusted to correct the solution cavity interpretation result of the three-dimensional seismic exploration.

[0057] After the solution cavity rock formation parameters are corrected, continue to obtain the reconstructed three-dimensional geological model of the solution cavity in the salt mine area to be measured according to the corrected solution cavity rock formation parameters and the geological and production data of the salt mine area to be measured, and then continue to match the reconstructed three-dimensional geological model of the solution cavity with the spatial form and volume of the target solution cavity included in the sonar detection result. If the match is successful, the iteration ends; if the match fails, continue to correct the solution cavity interpretation result of the three-dimensional seismic exploration until the match is successful.

[0058] In the embodiment of the present invention, after the sonar detection result fails to match the three-dimensional seismic exploration result, through the iterative process, the sonar detection result is used to correct the solution cavity rock formation parameters. Thus, the three-dimensional geological model of the solution cavity is continuously updated during the iterative process, so that the three-dimensional geological model of the solution cavity can more accurately depict the spatial form and volume of the solution cavity in the salt mine area to be measured.

[0059] The following describes the fine detection device for salt mine solution cavities based on three-dimensional seismic and sonar detection technologies provided by the present invention. The fine detection device for salt mine solution cavities based on three-dimensional seismic and sonar detection technologies described below can be correspondingly referred to the fine detection method for salt mine solution cavities based on three-dimensional seismic and sonar detection technologies described above.

Among them, the construction module 601 is used to construct a three-dimensional geological model of the solution cavities in the salt mine area to be measured according to the solution cavity rock layer parameters obtained by three-dimensional seismic exploration; the detection module 602 is used to perform sonar detection on a preset number of target solution cavities in the salt mine area to be measured to obtain the spatial form and volume of the target solution cavities. The preset number is less than the total number of solution cavities in the salt mine area to be measured, and the target solution cavity is any one of the solution cavities in the salt mine area to be measured; the matching module 603 is used to match the spatial form and volume of the target solution cavity with the three-dimensional geological model of the solution cavity; the determination module 604 is used to, when the matching is successful, determine the spatial form and volume of each solution cavity in the salt mine area to be measured according to the three-dimensional geological model of the solution cavity.

Therefore, the beneficial effects of the fine detection device for salt mine solution cavities based on three-dimensional seismic and sonar detection technologies will not be elaborated here.
