Description

Technical Field

[0001] The present invention relates to the field of oil exploration, and in particular, to a method, device, storage medium, and electronic device for optimizing seismic construction boundaries. Background Art

[0002] Seismic exploration is the most effective method for discovering oil and gas resources. By utilizing the differences in the elasticity and density of underground media, and through observing and analyzing the response of the earth to artificially excited seismic waves, the properties and forms of underground rock formations are inferred to predict mineral resources such as oil, natural gas, and coal. Seismic exploration can be divided into three stages: seismic data acquisition, seismic data processing, and seismic data interpretation. Seismic data acquisition is the primary step of seismic exploration, which requires arranging multiple geophones at equal intervals along seismic survey lines in the field to receive seismic wave signals excited by artificial seismic sources, and recording seismic data through seismic instruments.

[0003] Currently, before conducting 3D seismic exploration, it is necessary to carry out technical design and construction design for the 3D seismic data acquisition work in the exploration area. After the technical scheme is determined, it is necessary to deploy a full-coverage boundary and arrange the observation system.

[0004] However, in order to improve the seismic imaging accuracy for oil and gas exploration, this method needs to increase the relational slices of the observation system. The increase in relational slices will result in too many geophone points arranged outside the excitation boundary, and the construction boundary is larger than the excitation boundary and the full-coverage boundary. Some geophone points outside the excitation boundary are not necessary for pre-stack migration imaging within the full-coverage range. Therefore, the construction efficiency is relatively low.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, 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 of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] In the related art, before conducting three-dimensional seismic exploration, technical design and construction design are carried out for the three-dimensional seismic data acquisition work in the exploration area. According to the determined design, the full-coverage boundary is deployed, and the observation system is arranged. However, in order to improve the seismic imaging accuracy for oil and gas exploration, this method needs to increase the relational slices of the observation system, resulting in too many geophone points arranged outside the excitation boundary, and the construction boundary is larger than the excitation boundary and the full-coverage boundary. Since some geophone points outside the excitation boundary are not necessary for the pre-stack migration imaging within the full-coverage range, the construction efficiency is low.

[0038] In this embodiment, the optimal construction boundary that satisfies pre-stack migration imaging is quantitatively determined through the illumination analysis method, redundant additional arrays are reduced, and the three-dimensional seismic construction boundary is reduced without affecting the migration imaging effect, featuring improved construction efficiency.

[0039] See Figure 1 , an embodiment of the present invention provides a method for optimizing the seismic construction boundary. This method can be applied to the construction plan for optimizing the three-dimensional seismic construction boundary, and this method may include the following steps:

[0040] S101. Obtain the additional array outside the excitation boundary of the full-array observation plan arranged for the target area, and establish multiple observation plans based on the pre-set reduction strategy for the additional array outside the excitation boundary. Each observation plan corresponds to a seismic construction boundary;

[0041] In this embodiment, the excitation boundary is the change of the underground structure that causes the seismic wave to reflect, refract, and scatter when propagating underground. These changes in interfaces or structures will form reflection seismic phases in the seismic record, providing information about the underground structure. In seismic exploration, additional arrays outside the excitation boundary are used for data acquisition. When the distance between the excitation point and the geophone is far, since the long-distance propagation path can penetrate the underground structure better, it can provide deeper underground information and play an important role in the imaging of deep targets.

[0042] In this embodiment, as an alternative embodiment, additional arrays are added outside the excitation boundary of the full permutation observation scheme arranged according to the target area, and the additional arrays outside the excitation boundary are reduced according to different reduction strategies to establish multiple observation schemes. In this embodiment, as an alternative embodiment, the number of observation schemes is greater than or equal to 2.

[0043] In this embodiment, as an alternative embodiment, the full permutation observation scheme may include an orthogonal full permutation layout scheme.

[0044] In this embodiment, as an alternative embodiment, multiple observation schemes are established based on a pre-set reduction strategy for additional arrays outside the excitation boundary, including:

[0045] Obtain the number of receiving channels of the full permutation observation scheme;

[0046] Set the number of additional arrays outside the excitation boundary of the first observation scheme to half of the number of receiving channels;

[0047] Set the number of additional arrays outside the excitation boundary of the second observation scheme to one-quarter of the number of receiving channels.

[0048] The observation scheme includes an orthogonal full permutation layout scheme.

[0049] In this embodiment, as an alternative embodiment, the number R of additional arrays outside the excitation boundary can be reduced according to the following formula:

[0050]

[0051] In the formula, A is half of the number of receiving channels of the full permutation observation scheme, x is the number of observation schemes established, and the value of x is an integer greater than or equal to 2.

[0052] In this embodiment, as an alternative embodiment, the reduction strategy for additional arrays outside the excitation boundary can also be in the form of an exponent of two-thirds, an exponent of one-third, or other forms.

[0053] S102. Based on the target area and the full permutation observation system, establish a three-dimensional velocity model of the target area, and perform three-dimensional illumination on the three-dimensional velocity model in sequence according to the multiple observation schemes;

[0054] In this embodiment, as an alternative embodiment, a three-dimensional velocity model of the target area is established by using three-dimensional modeling software in combination with the seismic geological data of the target area and the full permutation observation system. Each observation scheme is arranged on the three-dimensional velocity model in sequence, and three-dimensional illumination analysis is performed separately using illumination software.

[0055] S103. Based on the illumination intensity of the deepest target layer in the fully covered area, set an illumination intensity threshold from the three-dimensional illumination results of the full permutation observation scheme;

[0056] In this embodiment, as an alternative embodiment, setting an illumination intensity threshold based on the illumination intensity of the deepest target layer in the full-coverage area includes:

[0057] Obtaining the maximum illumination intensity of the deepest target layer in the full-coverage area;

[0058] Calculating the product of the maximum illumination intensity and a preset illumination coefficient to obtain the illumination intensity threshold, where the illumination coefficient is set between 0.75 and 0.95.

[0059] In this embodiment, as an alternative embodiment, the illumination coefficient can be set to 85%.

[0060] In this embodiment, as an alternative embodiment, according to the three-dimensional illumination result of the full permutation observation scheme, select the deepest target layer in the full-coverage area and extract the illumination intensity curve. Denote the maximum illumination intensity of the deepest target layer in the full-coverage area as E max , and calculate the threshold of the illumination intensity according to the preset illumination coefficient. As an alternative embodiment, the illumination coefficient can be set to 85% as the threshold value E t .

[0061] S104. Obtain the illumination observation intensity of the deepest target layer in the multiple observation schemes, and select the observation schemes with the illumination observation intensity greater than the illumination intensity threshold, so as to perform the construction of the target area according to the seismic construction boundary of the selected observation scheme.

[0062] In this embodiment, as an alternative embodiment, respectively extract the illumination observation intensities E1, E2, E x ... at the same position of the deepest target layer in each observation scheme, and compare them with the threshold value E t . Regard the scheme with energy greater than E t as an observation scheme that meets the pre-stack migration imaging of the full-coverage area, and perform construction according to the seismic construction boundary of the selected observation scheme as the finally optimized three-dimensional seismic exploration construction boundary.

[0063] In this embodiment, as an alternative embodiment, in practical applications, a predetermined depth can also be selected according to actual needs.

[0064] In this embodiment, by obtaining the additional arrays outside the excitation boundary of the full permutation observation scheme arranged for the target area, and based on the pre-set reduction strategy for the additional arrays outside the excitation boundary, multiple observation schemes are established, and each observation scheme corresponds to a seismic construction boundary; based on the target area and the full permutation observation system, a three-dimensional velocity model of the target area is established, and three-dimensional illumination is performed on the three-dimensional velocity model in sequence according to the multiple observation schemes; from the three-dimensional illumination results of the full permutation observation scheme, an illumination intensity threshold is set based on the illumination intensity of the deepest target layer in the fully covered area; the illumination observation intensity of the deepest target layer in the multiple observation schemes is obtained, and the observation schemes with the illumination observation intensity greater than the illumination intensity threshold are selected, so as to implement the construction of the target area according to the seismic construction boundary of the selected observation scheme. In this way, the optimal construction boundary that meets the pre-stack migration imaging is determined by using the three-dimensional illumination analysis method. By performing illumination analysis and comparison on the observation schemes with different additional arrays, and according to the illumination intensity energy curve of the main target layer in the fully covered area, the illumination intensity of each observation scheme is quantitatively analyzed, and the optimal construction boundary is selected, which has better construction efficiency and applicability.
