Description

Technical Field

[0001] The present invention relates to the field of geological prospecting technology, and in particular to a micro-motion prospecting construction method, system, computer equipment and storage medium. Background Art

[0002] Micromotion refers to the tiny vibrations caused by non-earthquakes that exist on the earth at all times. The micromotion detection method is based on the theory of stationary random processes and extracts the surface wave dispersion curve from the vertical component of the micromotion signal. It is a geophysical exploration method that obtains the shear wave velocity structure of the underground medium by inverting the dispersion curve to achieve the purpose of detection. The commonly used methods at present are the spatial autocorrelation method (SPAC) and the extended spatial autocorrelation method (ESPAC). The spatial autocorrelation method (SPAC) requires less equipment and has the highest detection accuracy, but the construction efficiency is low and the construction environment requirements are high. The extended spatial autocorrelation method (ESPAC) is an extension of the spatial autocorrelation method (SPAC). Because the SPAC method has high requirements for the construction environment, in the operating environment where it is not convenient to deploy the SPAC array, L-type, T-type, cross-type, linear array and other types can be used; this method effectively solves the situation of construction environment restrictions, especially the linear array, which is extremely convenient to deploy.

[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The micro-motion exploration construction method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Figure 1 As shown, the application environment includes a computer device 110 and a seismograph 120, wherein the computer device 110 and the seismograph 120 can communicate through a wireless network, a wired connection, etc. The computer device 110 can obtain construction conditions and construction layout drawings, and determine initial construction parameters according to the construction conditions; the computer device 110 can collect construction site data, determine target construction parameters according to the construction site data and construction conditions, and modify the construction layout drawings according to the target construction parameters to generate a site construction operation drawing; the engineer deploys the seismograph 120 at the construction site according to the site construction operation drawing, and collects exploration micro-seismic data for each measuring point through the seismograph 120; the seismograph 120 imports the exploration micro-seismic data into the computer device 110, and the computer device 110 can extract dispersion curves after data processing of the exploration micro-seismic data, and generate micro-seismic exploration profiles according to the exploration micro-seismic data and the dispersion curves. Among them, the computer device 110 can be, but not limited to, various personal computers, laptops, smart phones, robots, tablet computers and other devices.

[0045] In one embodiment, Figure 2 As shown, a micro-seismic exploration construction method is provided, comprising the following steps:

[0046] Step 202: The computer device obtains construction conditions and a construction layout diagram, and determines initial construction parameters according to the construction conditions.

[0047] Among them, a micro-seismic exploration construction method provided in this embodiment can be applied to locations with abundant noise sources. If the energy of natural source surface waves is equivalent in all directions, this application can be applied in downtown areas; if the energy of natural source surface waves mainly comes from one direction, this application can be applied next to railways or highways.

[0048] The construction conditions may be the exploration depth, exploration effect, measurement point data and other conditions that the construction project needs to meet. The construction layout drawing may be a rough drawing designed according to the construction project. Engineers can select the construction conditions from the construction project and input them into the computer equipment. Engineers can also input the construction layout drawing into the computer equipment by scanning.

[0049] After obtaining the construction conditions, the computer equipment can determine the initial construction parameters according to the construction conditions. The initial construction parameters can be used to indicate the total number of available seismographs owned by the construction unit, the detection depth, the distance between measuring points, the number of each array group, the distance between geophones, the number of measuring points each time, and the number of rolling seismographs each time.

[0050] Step 204, the computer equipment collects the construction site data, determines the target construction parameters according to the construction site data and the construction conditions, modifies the construction layout drawing according to the target construction parameters, and generates the on-site construction operation drawing.

[0051] The construction site data may be data obtained after engineers place seismographs at the construction site for experiments. The engineers may input the collected construction site data into a computer device. The computer device may adjust the initial construction parameters according to the construction site data and construction conditions, thereby determining the target construction parameters. In this embodiment, the determined target construction parameters may include the total number of available seismograph channels, the detection depth, the spacing between measuring points, the number of each array group, the spacing between geophones, the number of measuring points each time, and the number of rolling seismographs each time.

[0052] Computer equipment can adjust the construction layout drawing according to the target construction parameters to obtain the on-site construction operation drawing.

[0053] In step 206, the engineer deploys seismographs at the construction site according to the on-site construction work map, and uses the seismographs to collect exploration micro-seismic data at each measuring point in a rolling manner.

[0054] After the computer equipment generates the on-site construction work drawing, it can display the on-site construction work drawing in the display interface for engineers to view.

[0055] Engineers can deploy seismographs at the construction site according to the on-site construction work drawing. For example, when the on-site construction work drawing shows that N = 20 seismographs and n = 9 seismographs per array can meet the exploration depth requirements, then the number of micro-motion measurement points each time is M = 12, and the number of rolling channels each time is 12. Engineers can deploy seismographs at the construction site according to the on-site construction work drawing according to N = 20 seismographs and n = 9 seismographs per array.

[0056] In this embodiment, engineers can deploy seismometers in a rolling manner to collect exploration micro-seismic data at each measuring point, thereby collecting each exploration micro-seismic data at each measuring point.

[0057] In step 208, the seismograph imports the exploration micro-seismic data into the computer device, and the computer device processes the exploration micro-seismic data to extract the dispersion curve, and generates a micro-seismic exploration profile according to the exploration micro-seismic data and the dispersion curve.

[0058] After each seismograph collects each exploration micro-motion data of each measuring point, the collected exploration micro-motion data can be uniformly imported into a computer device.

[0059] In this embodiment, the construction conditions and construction layout drawings are obtained by computer equipment, and the initial construction parameters are determined according to the construction conditions; the computer equipment collects construction site data, determines the target construction parameters according to the construction site data and construction conditions, and modifies the construction layout drawings according to the target construction parameters to generate the on-site construction operation drawings; the engineer deploys the seismograph at the construction site according to the on-site construction operation drawings, and collects the exploration micro-seismic data of each measuring point in a rolling manner through the seismograph; the seismograph imports the exploration micro-seismic data into the computer equipment, and the computer equipment extracts the dispersion curve after data processing of the exploration micro-seismic data, and generates the micro-seismic exploration profile according to the exploration micro-seismic data and the dispersion curve. The seismograph is reasonably deployed according to the construction conditions and the construction site data to complete the construction, and multiple measuring points can be explored and rolled at one time, which improves the efficiency of micro-seismic exploration; and the efficient micro-seismic exploration construction greatly reduces the cost of each micro-seismic measuring point, improves the competitiveness of micro-seismic exploration in other geophysical exploration methods, and makes micro-seismic exploration more suitable for production.

[0060] In one embodiment, a micro-seismic exploration construction method provided may also include a process of determining initial construction parameters, the specific process including: the computer equipment determines the exploration depth and the measurement point spacing according to the construction conditions, and obtains a pre-set parameter relationship formula; the computer equipment calculates and determines the initial construction parameters according to the exploration depth, the measurement point spacing, and the parameter relationship formula.

[0061] The construction conditions include various parameters involved in the construction project, and the computer equipment can determine the exploration depth H and the measurement point spacing D from the various parameters involved in the construction conditions. The relationship formula between parameters can be preset, and there can be 5 relationship formulas between parameters, namely: d = D; n = [H / (1.5 ~ 2.5) d] + 1; n is a cardinality ≥ 7; M = N-n + 1; m = M. Among them, d represents the distance between seismographs, D represents the distance between measurement points, n represents the number of each array, H represents the exploration depth, M represents the number of measurement points each time, and m represents the number of rolling seismographs each time.

[0062] The computer equipment can calculate the initial construction parameters based on the parameters that have been obtained and the relationship formula between the parameters. For example, taking the exploration depth H = 100m and the measurement point spacing D = 5m as an example: the formula calculates that the seismograph spacing d = 5m, n = 9, 11, 13, 15.

[0063] In one embodiment, a micro-seismic exploration construction method provided may also include a process of testing seismographs, and the specific process includes: engineers perform consistency tests on each seismograph at the construction site to obtain test results of each seismograph, and determine the operable seismographs and the number of seismographs based on the test results; engineers collect rough data through the operable seismographs at the construction site, and determine the number of each array group based on the rough data.

[0064] Engineers can conduct consistency tests on each seismograph at the construction site, where the consistency test can determine the number of available seismograph channels N. Specifically, engineers can take all seismographs to the construction site for consistency testing. If the coherence of all seismographs reaches above 0.9 in the effective frequency band, the next step of construction can be carried out. Otherwise, the seismographs need to be replaced or adjusted. If there are individual seismographs with poor consistency, they need to be removed or repaired, and the number of available seismographs N can be determined through consistency testing.

[0065] In this embodiment, engineers can also collect rough data through working seismographs at the construction site, for example, perform a detection depth test to determine the number n of each array group, take the maximum value of n according to the initial construction parameters, and arrange 15 seismographs in a row at a track spacing of 5 m on the survey line to be constructed, collect data for 20 minutes, select 1 to 9 channels as a group of arrays to extract surface wave dispersion curves, and perform inversion. If the detection depth can reach the expected requirement of 100 m, then n=9 is directly determined. If the detection depth of 100 m cannot be reached, then further repeat the previous operation, extract 1 to 11 channels as a group, extract dispersion curve data, and perform inversion... 1 to 13 channels are inverted as a group... until the detection depth of 100 m is reached, and finally determine the value of n.

[0066] In one embodiment, a micro-seismic exploration construction method is provided that may further include a process of determining target construction parameters, the specific process including: an engineer inputs the number of seismometers and the number of each array group as construction site data into a computer device; the computer device calculates the number of measuring points each time and the number of seismometers rolled each time based on the number of seismometers and the number of each array group, and uses the number of seismometers, the number of each array group, the number of measuring points each time and the number of seismometers rolled each time as target construction parameters.

[0067] After determining the number of seismographs and the number of each array, the engineer can input the number of seismographs and the number of each array into the computer device, and the computer device can calculate the number of measuring points each time and the number of rolling seismographs each time according to the pre-set parameter relationship formula. Specifically, the computer device can calculate the number of measuring points M each time according to M=N-n+1, ​​and then calculate the number of rolling seismographs m each time according to m=M. For example, in this embodiment, the total number of seismograph channels N=20 is determined, and the number of each array n=9, then the computer device can calculate the number of measuring points M=12 each time according to M=N-n+1, ​​and then calculate the number of rolling seismographs m=12 each time according to m=M. If n=11 is determined, then M=10, m=10.

[0068] In one embodiment, a micro-motion exploration construction method is provided that may further include a process of generating an on-site construction operation diagram and a shift report, the specific process including: the computer device searches for the position of each measuring point in the construction layout diagram, and marks each measuring point position in turn according to the target construction parameters to generate an on-site construction operation diagram; the computer device determines the coordinates of each measuring point according to the position of each measuring point, and generates a micro-motion exploration shift report according to the coordinates of each measuring point, the marked positions of each measuring point, and the on-site construction operation diagram.

[0069] The computer device may store a construction layout diagram, and the computer device may search for the location of each measuring point in the construction layout diagram, and mark the location of each measuring point according to the determined target construction parameters. Specifically, the computer device may also mark the station number and the measuring line number of the seismograph according to the target construction parameters, thereby generating a site construction operation diagram.

[0070] Taking the detection depth H = 100m and the micro-motion measuring point distance D = 5m as an example, the distance between seismographs is d = 5m. Assuming that the experiment confirms that the total number of seismograph channels N = 20 and the number of channels of each array seismograph n = 9 can meet the exploration depth requirements, then the number of micro-motion measuring points each time is M = 12, and the number of rolling channels each time is 12. The computer equipment can use this parameter to mark the construction layout diagram and obtain the on-site construction operation diagram. Figure 3 As shown, Z1, Z2... represent the station number of the seismograph, W1, W2... represent the micro-seismic measurement point number, the survey line number is line 1, the direction is due east -90°, "1 line 1 measurement" represents the first arrangement of the seismograph on line 1, "1 line 2 measurement" represents the second arrangement of the seismograph on line 1, and so on. In this embodiment, 1 line 2 measurement demonstrates the process of how the seismograph is rolled for construction.

[0071] like Figure 3As shown, in this embodiment, since the distances between each measuring point and the seismograph are equal and arranged in a straight line, the center point of the Z1-Z9 measuring stations is the Z5 measuring station, and the position of the Z5 measuring station coincides with the position of the W1 measuring point. The Z1-Z9 seismographs are selected as a group of ESPAC linear arrays, and the dispersion curve measured by them is the dispersion curve below the W1 measuring point. By extracting the dispersion curve, the phase velocity value and the apparent shear wave value below the W1 point can be obtained, and the lithology below it can be further inverted to achieve the exploration purpose; similarly, the W2 measuring point is located at the center of the Z2-Z10 measuring stations, and the Z2-Z10 seismographs are selected as a group of linear arrays to extract the dispersion curve below. The phase velocity value and apparent shear wave value below point W2 can be obtained by using the linear array, and the lithology below it can be further inverted..., W12 selects Z12-Z20 as a group of linear arrays, and the phase velocity value and apparent shear wave value below point W12 can be obtained by extracting the dispersion curve below, and the lithology below it can be further inverted; therefore, the first linear array of 20 seismic instruments arranged on survey line 1 can complete the micro-seismic exploration points of 12 points at a time, and 12 dispersion curves can be obtained, and the lithology below the 12 points can be inverted, which is recorded as 1 line 1 survey, and the spacing between each survey point of 1 line 1 survey is 5m, the survey depth is 100m, and the length of one survey line is 40m.

[0072] When the first survey is completed, the 12 seismometers behind are moved to the front survey point in the order of the seismometer numbers from small to large: Z1 is moved to the position of survey point W13, Z2 is moved to the position of survey point W14, and ... Z12 is moved to the position of survey point W24. After the rolling is completed, a new linear array consisting of 20 seismometers is formed to start the second micro-motion detection, which is recorded as 1 line 2 surveys. Then, repeat the station selection combination of 1 line 1 survey: Z13-Z1 measures W13 point, Z14-Z2 measures W14 point, Z15-Z3 measures W15 point, ... Z4-Z12 measures W24 point. The linear array of 20 seismic instruments on 1 line 2 survey can also complete the micro-seismic exploration of 12 points in one arrangement, and 12 dispersion curves can be obtained, and the lithology below the 12 points can be inverted. The spacing between each measuring point of 1 line 1 survey is 5m, and the measuring depth is 100m. The final measuring point of 1 line 1 survey is W12, and the starting point of 1 line 2 survey is W13. The spacing between the two measuring points is 5m, so after rolling again, the effective measuring points of the two micro-seismic detections are seamlessly connected, without duplication and omission. The same principle can be used to complete the exploration of long micro-seismic survey lines.

[0073] In this embodiment, the computer equipment can generate a micro-seismic exploration team report according to the target construction parameters and the on-site construction operation diagram. Among them, in the micro-seismic exploration team report, the header is written in order as the survey line number, survey times, point number, design coordinates (X, Y, H), array seismograph number, acquisition start time, and acquisition duration (seconds). Among them, the survey line number, survey times, point number, and design coordinates correspond to each other in the design diagram, and are filled in sequentially to ensure that the diagrams are consistent and checked with each other. The acquisition start time and acquisition duration are recorded on-site by engineers during construction and filled in on-site.

[0074] In one embodiment, a provided micro-seismic exploration construction method may also include a process in which engineers deploy seismographs at a construction site, and the specific process includes: engineers determine the measurement points and measurement line directions at the construction site according to the positions of each measurement point in the on-site construction work map; engineers deploy seismographs according to the measurement points and measurement line directions and the positions of each measurement point marked in the on-site construction work map; engineers upload the deployment data of the seismographs to a computer device, and the computer device verifies the deployment data according to a verification formula; engineers fill in a micro-seismic exploration class report based on the verified deployment data.

[0075] Engineers can use RTK to place points according to the on-site construction drawings, and use tape measure and compass to assist in the construction of the collection station. For example, if the starting point is W1, the RTK is used to find points, locate and mark on-site according to the coordinates corresponding to W1 in the micro-survey team report. The compass is used to determine the direction of the survey line in the on-site construction drawings, and the two-person forward and reverse measurement method is used to determine the direction of the survey line on-site. With W1 as the starting point, use a tape measure to measure B meters in the opposite direction of the survey line as the starting point 0m of the tape measure, where B = (n-1) / 2m.

[0076] Next, engineers can deploy seismometers, starting from the tape measure 0m, in the order of the seismometer numbers on the site construction work map, with a designed interval of d meters between seismometer tracks. On land, the seismometer needs to be connected to a large spur and inserted deep into the soil to ensure stability and be perpendicular to the ground; on hard roads, the seismometer needs to be removed from the large spur, and the bottom of the seismometer needs to be firmly attached to the hard roadside with plaster and be perpendicular to the ground.

[0077] After all the seismographs are deployed, engineers can check the arrangement of the seismographs to confirm that the arrangement is correct. Engineers can verify the corresponding positions and arrangement combinations of the measuring points and stations for each roll based on the verification formula. In this embodiment, the starting point is Wx, and the Wx point is arranged from Z1. The total number of measuring stations is N, and the number of autocorrelation measuring stations at each point is n. The Wx points are arranged in order from Z1, and each measuring point M=each rolling measuring station m. Then the autocorrelation measuring station numbers of the n channels corresponding to the Wy point are: if yx≤N, the starting measuring station number at point y is Z(y-x+1), and the ending station number is Z(y-x+n); if (y-x+n)>N, the ending station number is Z(y-x+nN); if yx>N, the starting measuring station number at point y is Z(y-x+1)mod N, and the ending station number is Z[(yx)mod N]+n; if [(yx)mod N]+n>N, the ending station number is Z[(yx)mod N]+nN. Among them, x~y are arranged in order from small to large.

[0078] Next, data collection can begin. After a group of N seismographs are deployed, data collection begins. The start time of data collection is recorded on the record sheet. Each data collection takes 20 to 30 minutes. During this period, RTK can be used to measure the point of each seismograph, and the actual coordinates of the point number corresponding to the seismograph are recorded. During the collection, in addition to the surveyors, try to ensure that there are no other pedestrians near the seismograph to interfere. The surveyors should also try to walk lightly and not touch the station. After the collection is completed, record the collection time.

[0079] After the first survey is completed, the second survey can be carried out, that is, the second deployment and data collection can be carried out. According to the on-site construction work map, the m seismometers behind are moved to the front measurement point in the order of the seismometer numbers from small to large and with a track spacing of d meters. After the second survey is completed, the engineer can carry out the third survey, and the method of the third survey is the same as that of the first and second surveys. Engineers can fill in the micro-seismic exploration class report based on the verified deployment data.

[0080] In one embodiment, a micro-seismic exploration construction method provided may also include a process of data processing and generating a profile diagram, and the specific process includes: a computer device slices the data recorded in the micro-seismic exploration class report, and arranges and organizes the sliced ​​data according to the measuring station array corresponding to each measuring point, and extracts a dispersion curve from the organized data and the exploration micro-seismic data; the computer device inverts the velocity value below each measuring point according to the dispersion curve, and generates a micro-seismic exploration profile diagram.

[0081] Computer equipment can export data from the seismograph, slice the data uniformly according to the upper acquisition start time and acquisition duration of each measurement record in the microseismic exploration team report, and arrange and organize the sliced ​​data according to the station array corresponding to each measuring point. Verification will be performed during the sorting process. After each measuring point is arranged correctly, the data processing software in the computer equipment can be used to extract the dispersion curve and invert the velocity value below each measuring point to generate a microseismic exploration profile.

[0082] It should be understood that, although the various steps in the above-mentioned flow chart are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
