Abstract
Description
Technical Field
[0001] This application relates to the field of geophysical exploration technology. In particular, it relates to a seismic data correction method, apparatus, and computer equipment. Background Technology
[0002] Currently, in seismic exploration, seismic waves are primarily generated at the excitation point, and seismic data are acquired at the receiving point using geophones. For a single excitation point, it can be generated by sources in multiple directions. These sources can be sources along the survey line (equivalent to X-sources), sources perpendicular to the survey line and in the same plane as the survey line (equivalent to Y-sources), and sources perpendicular to the plane of the survey line (equivalent to Z-sources). For a single receiving point, a three-component geophone can be used to record the three-dimensional particle vibrations caused by different sources. The three components of this geophone are the X, Y, and Z components. Therefore, if an excitation point is generated three times sequentially by X-sources, Y-sources, and Z-sources, and each time the data is received by a three-component geophone, nine components of seismic data can be obtained, resulting in nine-component seismic data.
[0003] However, in actual seismic exploration, due to objective reasons such as topographic relief, multiple seismic sources may fail to be activated according to the preset activation direction, resulting in a certain deviation between the actual activation direction and the preset activation direction. In this case, the actual nine-component seismic data deviates from the theoretical nine-component seismic data, leading to poor accuracy of the seismic data. Therefore, it is necessary to correct the actual nine-component seismic data. Summary of the Invention

[0062] To make the technical solution and advantages of this application clearer, the embodiments of this application will be described in further detail below.
[0063] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0064] It should be noted that all information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.), and signals involved in this application have been authorized by the user or fully authorized by all parties, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the measurement angle parameters, measurement intensity parameters, and seismic data involved in this application were all obtained with full authorization.
[0065] This application provides a seismic data correction method, executed by a computer device, see [link to relevant documentation]. Figure 1 The method includes:
[0066] Step 101: The computer equipment acquires the first earthquake data obtained from multiple seismic sources.
[0067] Multiple sources include X-sources and Y-sources, and may also include Z-sources.
[0068] In one possible implementation, if multiple seismic sources, including an X-source and a Y-source, record the particle vibration at the receiving point using a three-component geophone, then the first seismic data is six-component seismic data.
[0069] In another possible implementation, if multiple seismic sources include an X-source, a Y-source, and a Z-source, and the vibration of the mass points is recorded at the receiving point using a three-component geophone, then the first seismic data is nine-component seismic data.
[0070] In another possible implementation, the computer device first acquires nine-component seismic data, then acquires three-component seismic data corresponding to the X source and three-component seismic data corresponding to the Y source from the nine-component seismic data, and combines the three-component seismic data corresponding to the X source and the three-component seismic data corresponding to the Y source to form the first seismic data.
[0071] Therefore, the first earthquake data can be either six-component or nine-component earthquake data, without any specific limitation.
[0072] Step 102: The computer equipment acquires the first measurement angle corresponding to the first seismic data.
[0073] The first measurement angle parameter is used to represent the angle between the survey line direction corresponding to the first seismic data and the first horizontal component.
[0074] For example, if the first horizontal component is the Y component, then the first measurement angle parameter is the angle between the survey line direction corresponding to the first seismic data and the Y component, which can be expressed as θ.
[0075] Step 103: The computer equipment acquires multiple second measurement angle parameters, multiple third measurement angle parameters, and multiple measurement intensity parameters corresponding to multiple seismic sources.
[0076] The second measurement angle parameter is used to represent the angle between the excitation direction of the source and the first vertical component. The third measurement angle parameter is used to represent the angle between the excitation direction of the source and the first horizontal component. The measurement intensity parameter is used to represent the magnitude of the force excited by the source. One source corresponds to one second measurement angle parameter, one third measurement angle parameter and one measurement intensity parameter.
[0077] Wherein, the first vertical component is the Z component, and the first horizontal component can be either the X component or the Y component. In this embodiment, only the Y component as the first horizontal component is used as an example for explanation.
[0078] In this embodiment, the coordinate axis directions can be predefined in a Cartesian three-dimensional coordinate system. For example, the first horizontal component is the Y component, the second horizontal component is the X component, the positive direction of the X component is east, the positive direction of the Y component is north, and the positive direction of the Z component is vertically upward. The excitation direction of the seismic source can be defined as a vector in the Cartesian three-dimensional spatial coordinate system, referred to here as the excitation vector. This excitation vector can be described by a second measurement angle parameter and a third measurement angle parameter.
[0079] First: The angle between the excitation vector and the Z component is represented by the second measured angle parameter, with the positive direction of the Z component being 0° and clockwise rotation being positive;
[0080] Second: The angle between the projection of the excitation vector onto the XY plane and the Y component is represented by the third measured angle parameter. The positive direction of the Y component is 0°, and when rotated clockwise towards the X component, the positive direction of the X component is 90°.
[0081] For example, see Figure 2 The second measurement angle parameter is denoted by β, and the third measurement angle parameter is denoted by α. Then the excitation direction of the earthquake source... It can be represented as (β, α). This represents the projection of the excitation vector onto the XOY plane. Indicates the direction of the survey line.
[0082] If the first earthquake data is six-component earthquake data, then the number of the second measurement angle parameter, the third measurement angle parameter, and the measurement intensity parameter are all 2. If the first earthquake data is nine-component earthquake data, then the number of the second measurement angle parameter, the third measurement angle parameter, and the measurement intensity parameter are all 3.
[0083] It should be noted that if the magnitude of the force excited by the seismic source is defined as a standard value, then the measured intensity parameter can be normalized to a unit of 1. The second and third measured angle parameters and the measured intensity parameter for each excitation can be obtained during construction. Furthermore, the computer equipment can execute steps 101-103 sequentially, or it can execute steps 102 and 103 first, then step 101, or it can execute step 103 first, then steps 101 and 102. There is no specific limitation on the order in which the computer equipment executes steps 101-103.
[0084] Step 104: The computer device determines, based on the first measurement angle parameter, multiple second measurement angle parameters, and multiple third measurement angle parameters, the first measurement intensity parameter on the first horizontal component and the second measurement intensity parameter on the second horizontal component, respectively.
[0085] The first measurement intensity parameter and the second measurement intensity parameter are used to represent the measurement intensity of the measurement intensity parameter in the first horizontal component and the measurement intensity in the second horizontal component, respectively.
[0086] If the first level component is a Y component, then the second level component is an X component. If the first level component is an X component, then the second level component is a Y component. In this embodiment, only the example of the first level component being a Y component and the second level component being an X component is used for illustration.
[0087] In this step, the process by which the computer equipment determines the first measured intensity parameter of the first horizontal component corresponding to a seismic source can be achieved through the following steps (A-1) to (A-4), including:
[0088] (A-1) The computer equipment determines the sine value of the second measurement angle parameter and obtains the value of the first parameter.
[0089] For example, if the second measured angle parameter is denoted as β, then the first parameter value is denoted as sinβ.
[0090] (A-2) The computer equipment determines the difference between the first and third measurement angle parameters to obtain the fourth angle parameter.
[0091] In this step, the computer device determines the value after subtracting the third measurement angle parameter from the first measurement angle parameter to obtain the fourth angle parameter.
[0092] For example, if the first measured angle parameter is denoted as θ and the third measured angle parameter is denoted as α, then the fourth angle parameter can be denoted as θ-α.
[0093] (A-3) The computer equipment determines the sine value of the fourth angle parameter and obtains the value of the second parameter.
[0094] If the fourth angle parameter is represented as θ-α, then the value of the second parameter can be represented as sin(θ-α).
[0095] (A-4) The computer device determines the first measurement intensity parameter based on the first parameter value, the second parameter value, and the measurement intensity parameter.
[0096] The computer equipment determines the product of the measured intensity parameter, the first parameter value, and the second parameter value to obtain the first measured intensity parameter. For example, if the measured intensity parameter is represented as g, then the first measured intensity parameter can be represented as g×sinβ×sin(θ-α).
[0097] In this step, the process by which the computer equipment determines the second measurement intensity parameter of the second horizontal component corresponding to a seismic source can be achieved through the following steps (B-1) to (B-2):
[0098] (B-1) The computer equipment determines the cosine value of the fourth angle parameter and obtains the value of the third parameter.
[0099] The value of this third parameter can be expressed as cos(θ-α).
[0100] (B-2) The computer equipment determines the second measurement intensity parameter based on the third parameter value, the first parameter value, and the measurement intensity parameter.
[0101] The computer equipment determines the product of the measured intensity parameter, the third parameter value, and the first parameter value to obtain the second measured intensity parameter, which can be expressed as g×sinβ×cos(θ-α).
[0102] In this step, the computer equipment can determine the first measurement intensity parameter first, and then the second measurement intensity parameter, or it can determine the second measurement intensity parameter first, and then the first measurement intensity parameter, with specific limitations applied. If the second measurement intensity parameter is determined first, the computer equipment first determines the fourth angle parameter based on the first and third measurement angle parameters, and then executes steps (B-1) to (B-2) to obtain the second measurement intensity parameter. In this case, when determining the first measurement intensity parameter, the sine value of the fourth angle parameter can be directly determined, without needing to determine the fourth angle parameter again.
[0103] Step 105: The computer device determines the third measurement intensity parameter on the first vertical component based on the multiple second measurement angle parameters.
[0104] The third measurement intensity parameter is used to represent the measurement intensity of the measurement intensity parameter on the first vertical component. One measurement intensity parameter corresponds to the first measurement intensity parameter, the second measurement intensity parameter, and the third measurement intensity parameter.
[0105] The computer equipment determines the cosine value of the second measurement angle parameter corresponding to a seismic source, obtains the fourth parameter value, and determines the third measurement intensity parameter based on the fourth parameter value and the measurement intensity parameter corresponding to the seismic source.
[0106] In this implementation, the computer device determines the negative of the product of the fourth parameter value and the measured intensity parameter to obtain the third measured intensity parameter. For example, if the fourth parameter value is represented as cosβ, then the third intensity parameter can be represented as -g×cosβ. The computer device obtains multiple third measured intensity parameters through this method.
[0107] Step 106: The computer device determines the first correction matrix based on the first measurement intensity parameter, the second measurement intensity parameter, and the third measurement intensity parameter corresponding to the multiple measurement intensity parameters.
[0108] This step can be achieved through the following steps (1) to (3), including:
[0109] (1) The computer device determines that the first, second and third measurement intensity parameters corresponding to a measurement intensity parameter are elements of a row in the first correction matrix, thus obtaining multiple row elements.
[0110] If the earthquake source includes an X-source and a Y-source, then the first, second, and third measured intensity parameters corresponding to the measured intensity parameters of the X-source form the elements of one row in the first calibration matrix, and the first, second, and third measured intensity parameters corresponding to the measured intensity parameters of the Y-source form the elements of one row in the first calibration matrix, ultimately resulting in two rows of elements, with each row containing three elements.
[0111] If the earthquake source includes X source, Y source and Z source, then except for X source and Y source, the first measurement intensity parameter, second measurement intensity parameter and third measurement intensity parameter corresponding to the measurement intensity parameter of Z source form the elements of one row in the first correction matrix, and finally obtain three rows of row elements, with each row containing three elements.
[0112] The order of elements in a row can be set and changed as needed, without any specific limitation. For example, the elements in a row can be arranged from left to right in the order of X, Y, and Z components, or in the order of X, Z, and Y components, or in the order of Y, X, or Z components.
[0113] If the earthquake source includes both X-source and Y-source, then the first correction matrix consists of two rows of elements. The order of these two rows can be set and changed as needed, and there is no specific limitation on this. For example, the first row may contain elements corresponding to the X-source and the second row may contain elements corresponding to the Y-source, or the first row may contain elements corresponding to the Y-source and the second row may contain elements corresponding to the X-source.
[0114] If the earthquake sources include X-ray, Y-ray, and Z-ray sources, then the first correction consists of three rows of elements. The order of these three rows can be set and changed as needed, and there is no specific limitation on this. For example, the first row may correspond to the X-ray source, the second row to the Y-ray source, and the third row to the Z-ray source; or the first row may correspond to the Y-ray source, the second row to the X-ray source, and the third row to the Z-ray source.
[0115] (2) The computer equipment determines that the first measurement intensity parameter, the second measurement intensity parameter, and the third measurement intensity parameter corresponding to the multiple measurement intensity parameters are elements of a column in the first correction matrix, thus obtaining multiple column elements.
[0116] The computer equipment determines multiple first measurement intensity parameters as one column, multiple second measurement intensity parameters as one column, and multiple third measurement intensity parameters as one column, thus obtaining three columns of column elements.
[0117] The order of the elements in these three columns can be set and changed as needed, without any specific limitation. For example, if the earthquake source includes an X-ray source and a Y-ray source, the first column contains the second measured intensity parameter of the corresponding intensity parameters of the X-ray source and the Y-ray source in the X component; the second column contains the first measured intensity parameter of the corresponding intensity parameters of the X-ray source and the Y-ray source in the Y component; and the third column contains the third measured intensity parameter of the corresponding intensity parameters of the X-ray source and the Y-ray source in the Z component. Similarly, if the earthquake source includes an X-ray source, a Y-ray source, and a Z-ray source, then the first column contains the second measured intensity parameter of the corresponding intensity parameters of the X-ray source, the Y-ray source, and the Z-ray source in the X component; the second column contains the first measured intensity parameter of the corresponding intensity parameters of the X-ray source, the Y-ray source, and the Z-ray source in the Y component; and the third column contains the third measured intensity parameter of the corresponding intensity parameters of the X-ray source, the Y-ray source, and the Z-ray source in the Z component.
[0118] (3) The computer device forms a first correction matrix by combining multiple row elements and multiple column elements.
[0119] If the earthquake source includes both X-source and Y-source, then a row contains three elements and a column contains two elements. For the elements in a row, the computer device can arrange them from left to right in the order of X-component, Y-component, and Z-component. For the elements in a column, the computer device can arrange them from top to bottom in the order of X-source and Y-source, forming the first correction matrix.
[0120] Accordingly, the first correction matrix can be expressed as:
[0121]
[0122] Where P represents the first correction matrix, g1, β1, and α1 represent the measured intensity parameter, second measured angle parameter, and third measured angle parameter of the X-source, respectively, g1×sinβ1×cos(θ-α1), g1×sinβ1×sin(θ-α1), and -g1×cosβ1 represent the second, first, and third measured intensity parameters of the X-source, respectively, g2, β2, and α2 represent the measured intensity parameter, second measured angle parameter, and third measured angle parameter of the Y-source, respectively, g2×sinβ2×cos(θ-α2), g2×sinβ2×sin(θ-α2), and -g2×cosβ2 represent the second, first, and third measured intensity parameters of the Y-source, respectively.
[0123] It should be noted that when the seismic source includes both an X-source and a Y-source, the excitation directions of both sources are within the XOY plane. Therefore, the angle between the excitation directions of these two sources and the Z-component is 90°, meaning that the second measurement angle parameters β1 and β2 are both 90°. In this case, the first correction matrix can be expressed as:
[0124]
[0125] Computer devices may also arrange row and column elements into a first correction matrix in other orders, without specific limitations.
[0126] If the earthquake source includes X-source, Y-source, and Z-source, then a row contains three elements and a column contains three elements. For the elements in a row, the computer device can arrange them from left to right in the order of X-component, Y-component, and Z-component. For the elements in a column, the computer device can arrange them from top to bottom in the order of X-source, Y-source, and Z-source, forming the first correction matrix.
[0127] Accordingly, the first correction matrix can be expressed as:
[0128]
[0129] Where g3, β3, and α3 represent the measured intensity parameter, the second measured angle parameter, and the third measured angle parameter of the Z-source, respectively, and g3×sinβ3×cos(θ-α3), g3×sinβ3×sin(θ-α3), and -g3×cosβ3 represent the second measured intensity parameter, the first measured intensity parameter, and the third measured intensity parameter corresponding to the Z-source, respectively.
[0130] Step 107: The computer device determines the inverse matrix of the first correction matrix to obtain the second correction matrix.
[0131] If the first correction matrix is represented as:
[0132]
[0133] The second correction matrix can then be expressed as:
[0134]
[0135] Among them, P -1 This represents the second correction matrix.
[0136] If the first correction matrix is represented as:
[0137]
[0138] The second correction matrix can then be expressed as:
[0139]
[0140] In the embodiments of this application, the computer device can determine the inverse matrix of the first correction matrix by means of the adjoint matrix method, elementary transformation method and other methods, without making specific limitations.
[0141] It should be noted that before determining the inverse of the first correction matrix, the computer equipment first determines whether the first correction matrix is invertible. If the seismic source includes an X-source and a Y-source, the process by which the computer equipment determines whether the first correction matrix is invertible can be as follows: the computer equipment determines whether the excitation direction of the X-source is parallel to the excitation direction of the Y-source. If the excitation direction of the X-source is not parallel to the excitation direction of the Y-source, the computer equipment determines that the first correction matrix is invertible, and then determines the inverse of the first correction matrix.
[0142] If the earthquake sources include X-source, Y-source, and Z-source, the process by which the computer equipment determines whether the first correction matrix is invertible can be as follows: The computer equipment determines whether the excitation directions of X-source and Y-source are parallel, whether the excitation directions of Y-source and Z-source are parallel, and whether the excitation directions of X-source, Y-source, and Z-source are simultaneously in the same plane. If the excitation directions of X-source and Y-source are not parallel, the excitation directions of Y-source and Z-source are not parallel, and the excitation directions of X-source and Z-source are not simultaneously in the same plane, then the computer equipment determines that the first correction matrix is invertible, and then determines the inverse matrix of the first correction matrix.
[0143] Step 108: The computer equipment determines the product of the first seismic data and the second correction matrix to obtain the second seismic data.
[0144] If the first earthquake data is six-component earthquake data, then the first earthquake data can be represented as:
[0145] Where U represents the first earthquake data, the row indices of the first and second rows represent the X-source and Y-source respectively, and the column indices of the first, second, and third columns represent the X-component, Y-component, and Z-component respectively. 11 U 12 and U 13 U represents the actual seismic data of the X-source in the X component, the actual seismic data of the X-source in the Y component, and the actual seismic data of the X-source in the Z component, respectively. 21 U 22 and U 23 These represent the actual earthquake data of the Y-source in the X component, the actual earthquake data of the Y-source in the Y component, and the actual earthquake data of the Y-source in the Z component, respectively.
[0146] The computer equipment determines the product of the first seismic data and the second correction matrix to obtain the theoretical second seismic data, which can be represented as: Where V represents the second earthquake data, V 11 V 12 and V 13 V represents the theoretical seismic data of the X-source in the X component, the theoretical seismic data of the X-source in the Y component, and the theoretical seismic data of the X-source in the Z component, respectively. 21 V 22 and V 23 These represent the actual earthquake data of the Y-source in the X component, the actual earthquake data of the Y-source in the Y component, and the actual earthquake data of the Y-source in the Z component, respectively.
[0147] If the first earthquake data is a nine-component earthquake data, then the first earthquake data can be represented as:
[0148] In this context, the subscript in the third row indicates the Z-source, U... 31 U 32 and U 33 These represent the actual earthquake data of the Z-source in the X component, the actual earthquake data of the Z-source in the Y component, and the actual earthquake data of the Z-source in the Z component, respectively.
[0149] The computer equipment determines the product of the first seismic data and the second correction matrix to obtain the second seismic data, which can be represented as: Among them, V 31 V 32 and V 33 These represent the theoretical seismic data of the Z-source in the X component, the theoretical seismic data of the Z-source in the Y component, and the theoretical seismic data of the Z-source in the Z component, respectively.
[0150] In this embodiment of the application, after the computer device obtains the second seismic data, it can determine seismic data with arbitrary excitation direction and arbitrary intensity based on the second seismic data. This process can be as follows: the computer device acquires a first preset angle parameter, a second preset angle parameter, and a preset intensity parameter, and determines the third seismic data based on the first measurement angle parameter, the first preset angle parameter, the second preset angle parameter, and the preset intensity parameter.
[0151] The first preset angle parameter and the second preset angle parameter are used to determine the preset excitation direction. The first preset angle parameter is used to represent the angle between the preset excitation direction and the first vertical component. The second preset angle parameter is used to represent the angle between the preset excitation direction and the first horizontal component. The third seismic data is the seismic data corresponding to the second seismic data under the survey line direction, the preset excitation direction and the preset intensity parameters.
[0152] In this implementation, the computer device determines a relation matrix based on the first measurement angle parameter, the first preset angle parameter, the second preset angle parameter, and the preset intensity parameter. The product of this relation matrix and the second seismic data is then determined to obtain the third seismic data. The process by which the computer device determines the relation matrix is similar to the process described above for determining the first correction matrix, and will not be repeated here.
[0153] For example, if the first measurement angle parameter is still represented as θ, the first preset angle parameter is represented as β′, the second preset angle parameter is represented as a′, and the preset intensity parameter is represented as g′, then the preset excitation direction can be represented as (β′, α′).
[0154] If the second earthquake data is nine-component earthquake data, then the relation matrix can be represented as [g′×sinβ′×cos(θ-α′)g′×sinβ′×sin(θ-α′)-g′×cosβ′], and the third earthquake data can be represented as:
[0155] W = [g′×sinβ′×cos(θ-α′)g′×sinβ′×sin(θ-α′)-g′×cosβ′]V, where W represents the third earthquake data and V represents the second earthquake data.
[0156] If the second earthquake data is six-component earthquake data, then the relation matrix can be represented as [g′×cos(θ-α′)g′×sin(θ-α′)], and the third earthquake data can be represented as: W=[g′×cos(θ-α′)g′×sin(θ-α′)]V.
[0157] The second preset angle parameter, the third preset angle parameter, and the preset intensity parameter can be set and changed as needed, and no specific limitations are imposed on them.
[0158] In this embodiment of the application, after obtaining the theoretical second seismic data, the computer device can synthesize a third seismic data with three components of arbitrary excitation direction and arbitrary output intensity.
[0159] This application provides a seismic data correction method. This method uses a first measurement angle parameter, multiple second measurement angle parameters corresponding to multiple seismic sources, multiple third measurement angle parameters, and multiple measurement intensity parameters to determine a first measurement intensity parameter on a first horizontal component, a second measurement intensity parameter on a second horizontal component, and a third measurement intensity parameter on a first vertical component. Based on the first, second, and third measurement intensity parameters corresponding to the multiple measurement intensity parameters, a first correction matrix is determined. This allows the actual first seismic data to be corrected using the first correction matrix to obtain theoretical seismic data, thereby improving the accuracy of the seismic data.
