[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0041] Example 1
[0042] like Figure 1 As shown, in this embodiment, the data-driven shot detection surface wave prediction method is primarily implemented based on a shot-detection seismic observation system configured in a cross configuration. In this system, a source line consisting of a plurality of vertically arranged shot points and a detection line consisting of a plurality of horizontally arranged detection points intersect in a cross configuration, such that the detection points on the detection line are located on either side of the source line. In this embodiment, the number of detection points on the detection lines on either side of the source line can be the same or different, and this is not limited by the present invention. Furthermore, the number of shot points on the source line and the number of detection points on the detection line can be the same or different, and this is not limited by the present invention.
[0043] like Figure 2 As shown, the shot detection surface wave prediction method provided in this embodiment mainly includes the following steps:
[0044] Construct a cross-arranged shot-detector seismic observation system, in which the source line composed of several vertically arranged shot points and the detection line composed of several horizontally arranged detection points intersect in a cross shape;
[0045] Acquire seismic data from a cross-arranged shot-detector seismic observation system and convert it from the time domain to the frequency domain.
[0046] Determine the number of shot points on the source line and the number of receiver points on the receiver line that participate in surface wave prediction, and group them into several shot-receiver pairs;
[0047] For each shot-check pair, the surface wave prediction result for each frequency component in the frequency domain seismic data is calculated using the following formula:
[0048]
[0049] The surface roll prediction results of all frequency components of all shot-detector pairs are converted from the frequency domain to the time domain to obtain the surface roll prediction results of the shot-detector seismic observation system.
[0050] The working principle of the above method is described in detail below.
[0051] The interchange theorem relates the seismic wave fields of two different states (e.g., due to two different energy source locations):
[0052]
[0053] and
[0054]
[0055] Where p A represents the sound pressure in state A, q A represents the source distribution under state A, v i,A represents the i-th component of the velocity of the particle in state A, and * represents the complex conjugate.
[0056] By replacing one of the states A, B, or C with a Green's function, convolution- and correlation-type expressions can be derived.
[0057] In the convolution-type interchange theorem, the state B is chosen as follows:
[0058]
[0059] The choice of state C in the correlation exchange theorem is:
[0060]
[0061] Where G(x, y) is the Green's function, which represents the pressure at position x caused by the earthquake source at position y, ω represents the angular frequency, ρ represents the density at the earthquake source position, and the partial derivative is is the derivative of the i-th coordinate of the earthquake source position,
[0062] use And the state of selecting equations (3) and (4) is obtained as follows:
[0063]
[0064]
[0065] Here, the prime sign indicates that the integration region in equation (6) is different from that in equation (5).
[0066] Substituting equation (6) into equation (5), and using the gun-check interchange G(x, x2) = G(x2, 2), we have:
[0067]
[0068] Using Green's functions between point x' on boundary S', point x on boundary S, and point x2, equation (7) expresses the relationship between the pressure at x2 caused by the source distribution defined by q(x) and the pressure on boundary S.
[0069] If q(x) = δ(x-x1) and p(x) = G(x, x1), then formula (7) is simplified to
[0070]
[0071] This formula indicates that the surface wave prediction record with the shot point position x1 and the receiver position x2 can be estimated by integrating the two surfaces S′ and S.
[0072] Based on the above principles, the prediction of shot-detector surface waves can be realized in the cross-arrangement domain.
[0073] The technical effect of the shot-detector wave prediction method of the present invention is illustrated below by using a specific example.
[0074] Reference Figure 2 , the source line where the shot points are located in the cross arrangement domain is taken as the source boundary, and the detection line where the detector is located is taken as the receiving boundary. Figure 3 The seismic data shown reconstruct the shot-to-receive (x1-x2) surface waves.
[0075] The specific implementation steps are as follows:
[0076] (1) Obtain seismic data from a cross-arranged shot-detector seismic observation system (e.g. Figure 3 shown);
[0077] (2) transforming seismic data from the time domain to the frequency domain using fast Fourier transform;
[0078] (3) Determine the source aperture parameter, i.e., the number of shot points in the surface integral S (3 to 7); determine the receiver aperture parameter, i.e., the number of receiver points in the surface integral S′ (3 to 7);
[0079] (4) For a set of shot detection pairs, select a frequency component;
[0080] (5) Select the source position as x1 and the detector position as x2, and use formula (8) to output the surface wave prediction record under the frequency component;
[0081] (6) For other frequency components, execute step (5);
[0082] (7) Repeat steps (4) to (6) for other gun inspection pairs;
[0083] (8) Transform the surface roll prediction records of all shot detection pairs from the frequency domain to the time domain to obtain the entire surface roll prediction results (such as Figure 4 shown).
[0084] Figure 3 It is the original ground seismic data, with a total of 263 channels and a channel spacing of 50 meters. Figure 4 Schematic diagram of the surface roll prediction results obtained using the method of the present invention. Figure 4 It can be seen that the predicted noise model is in good agreement with the actual data.
