TECHNICAL FIELD
[0001] The present application relates to the technical field of geophysical exploration, more particularly, to a method and device for calculating bin and fold of patch observation system, electronic equipment and medium. BACKGROUND
[0002] Ocean Bottom Node (OBN) exploration technology is a marine exploration technology that has gradually developed in recent years and has been widely used in oil and gas field exploration in various sea areas around the world, and good results have been achieved. OBN acquisition is generally affected by equipment and construction methods, and therefore a smaller number of receiving points and a larger number of shot points are used for acquisition, so that the patch observation system with multiple shot repetitions and fixed receiving arrangement becomes an important choice for OBN acquisition. The patch observation system only needs to be rolled longitudinally and transversely once to obtain a full-coverage cycle. In order to reduce the investment in OBN node acquisition equipment in OBN acquisition, a larger OBN point distance and a smaller shot point distance are generally used for construction. Because the OBN point distance is larger, the bin calculated by 1 / 2 bin distance and 1 / 2 shot point distance is not suitable for the actual acquisition requirements. This method of calculating the OBN acquisition bin is not necessarily suitable for OBN acquisition design. Similarly, the traditional method of calculating the longitudinal fold and transverse fold is also not suitable. Therefore, in order to play the role of the patch observation system in OBN acquisition and obtain high-quality imaging data, it is very important to accurately calculate the bin parameters and fold parameters in the patch observation system for the design of the acquisition scheme in OBN acquisition.
[0003] At present, a method for calculating the bin and fold of the patch observation system needs to be developed.

Those skilled in the art should understand that the examples are only for facilitating understanding of the present application, and any specific details thereof are not intended to limit the present application in any way.
[0048] Example 1
[0049] Figure 1 A flow chart showing steps of a method of calculating patch observation system bins and coverage times according to one embodiment of the present application is shown.
[0050] As shown in Figure 1 , the method of calculating patch observation system bins and coverage times comprises:
[0051] Step 101, calculating a longitudinal bin size of a patch observation system;
[0052] Step 102, calculating a lateral bin size of the patch observation system;
[0053] Step 103, calculating a longitudinal coverage times of the patch observation system;
[0054] Step 104, calculating a lateral coverage times of the patch observation system.
[0055] In one example, the longitudinal bin size is half of the greatest common divisor among a longitudinal shotpoint interval and a longitudinal receiver interval.
[0056] In one example, the lateral bin size is half of the greatest common divisor among a lateral shotpoint interval and a lateral receiver interval.
[0057] In one example, the longitudinal coverage times is:
[0058]
[0059] wherein F x is the longitudinal coverage times, Lcm is the least common multiple, NR x is the number of longitudinal receivers, RI x is the longitudinal receiver interval, SI x is the longitudinal shotpoint interval.
[0060] In one example, the lateral coverage times is:
[0061]
[0062] wherein F y is the lateral coverage times, Lcm is the least common multiple, NR y is the number of lateral receivers, RI y is the lateral receiver interval, SIy is the transverse shotpoint distance.
[0063] Specifically, the method selects corresponding calculation method according to the quantity relationship between the in-same-direction shotpoint distance and the in-same-direction receiver distance.
[0064] As the first limitation to the method, the in-same-direction only includes the longitudinal direction and the transverse direction. Generally, in seismic exploration, the direction along the arrangement is defined as the longitudinal direction, and the direction perpendicular to the arrangement is defined as the transverse direction. As the second limitation to the method, the observation system parameters comply with the current general parameter rules, that is, the receiver distance and the shotpoint distance have the minimum common multiple and common multiple that comply with the actual situation, etc.
[0065] The longitudinal bin size is equal to half of the greatest common divisor of the longitudinal shotpoint distance and the longitudinal receiver distance, and the specific calculation formula is:
[0066]
[0067] wherein, B x is the longitudinal bin grid, Gcd is the greatest common divisor, NR x is the longitudinal receiver distance, SI x is the longitudinal shotpoint distance.
[0068] The transverse bin size is equal to half of the greatest common divisor of the transverse shotpoint distance and the transverse receiver distance, and the specific calculation formula is:
[0069]
[0070] wherein, B y is the transverse bin grid, Gcd is the greatest common divisor, NR y is the transverse receiver distance, SI y is the transverse shotpoint distance.
[0071] The calculation of the specific coverage times is also divided into the following two directions:
[0072] The longitudinal coverage times are equal to the product of the longitudinal receiver number and the longitudinal receiver distance divided by the least common multiple of the longitudinal shotpoint distance and the longitudinal receiver distance, and the specific calculation formula is:
[0073]
[0074] wherein, F x is the longitudinal coverage times, Lcm is the least common multiple, NR x is the longitudinal receiver number, RI x is the longitudinal receiver distance, SI x is the longitudinal shotpoint distance.
[0075] The number of lateral coverages equals the product of the number of lateral detectors and the lateral detector distance, divided by the least common multiple of the lateral shot distance and the lateral receiver distance. The specific calculation formula is as follows:

[0085] In one example, the lateral element size is half the greatest common divisor of the lateral shot distance and the lateral receiver distance.
[0086] In one example, the number of vertical coverages is:
[0087]
[0088] Among them, F x For vertical coverage, Lcm is the least common multiple, and NR is the number of coverages. x RI is the number of longitudinal receiving points. x For longitudinal receiver point spacing, SI x The longitudinal excitation point spacing is denoted as .
[0089] In one example, the number of lateral coverages is:

[0092] Specifically, this method selects the appropriate calculation method based on the quantitative relationship between the distance between the shot points and the distance between the receiver points in the same direction.
[0093] As the first limitation of this method, "same direction" only includes longitudinal and transverse directions. Generally, in seismic exploration, the direction along which the array is arranged is defined as longitudinal, and the direction perpendicular to the array is defined as transverse. As the second limitation of this method, the observation system parameters conform to current general parameter laws, that is, the receiver distance and shot distance have a least common divisor and a common multiple that are consistent with reality.
[0094] The longitudinal element size is equal to half the greatest common divisor of the longitudinal shot distance and the longitudinal receiver distance. The specific calculation formula is as follows:
[0095]
[0096] Among them, B x The grid consists of vertical facets, Gcd is the greatest common divisor, and RI is the largest common divisor. x For longitudinal receiver point spacing, SI x The longitudinal excitation point spacing is denoted as .
[0097] The lateral element size is equal to half the greatest common divisor of the lateral shot distance and the lateral receiver distance. The specific calculation formula is as follows:
[0098]
[0099] Among them, B y The grid consists of horizontal elements, Gcd is the greatest common divisor, and RI is the largest common divisor. y SI is the lateral receiver point spacing. y The distance between the lateral excitation points is denoted as .
[0100] The calculation of specific coverage counts can be divided into the following two directions:
[0101] The longitudinal coverage number is equal to the product of the longitudinal detector number and the longitudinal detector distance, divided by the least common multiple of the longitudinal shot distance and the longitudinal receiver distance. The specific calculation formula is as follows:
[0102]
[0103] Among them, F x For vertical coverage, Lcm is the least common multiple, and NR is the number of coverages. x RI is the number of longitudinal receiving points. x For longitudinal receiver point spacing, SIx The longitudinal excitation point spacing is denoted as .
[0104] The number of lateral coverages equals the product of the number of lateral detectors and the lateral detector distance, divided by the least common multiple of the lateral shot distance and the lateral receiver distance. The specific calculation formula is as follows:
[0105]
[0106] Among them, F y NR represents the number of lateral coverages, Lcm is the least common multiple, and NR is the number of lateral coverages. y RI represents the number of horizontal receiving points. y SI is the lateral receiver point spacing. y The distance between the lateral excitation points is denoted as .
[0107] Example 3
[0108] A target area requires OBN seismic acquisition. Because OBN node equipment is expensive, while airgun-triggered shot points are less costly, given a fixed project budget, a patch observation system with repeated shot point firing and receiver array deployment and retrieval is highly effective. Based on the geological characteristics and geological tasks of the target area, the observation system was validated, and the following patch observation system was designed:
[0109] Number of receiver lines: 20
[0110] receiver line spacing: 175m
[0111] Number of channels per receiver line: 48
[0112] Lane spacing: 125m
[0113] Number of gun lines: 240
[0114] Gun line distance: 50m
[0115] Gun count: 256 guns
[0116] Gun distance: 25m
[0117] According to the observation system parameters, the longitudinal element size is equal to half the greatest common divisor of the longitudinal shot distance and the longitudinal receiver distance.
[0118]
[0119] The lateral element size is equal to half the greatest common divisor of the lateral shot distance and the lateral receiver distance:
[0120]
[0121] Calculations show that the longitudinal and transverse dimensions of the observation system are both 12.5m.
[0122] The longitudinal coverage number is equal to the product of the longitudinal detector number and the longitudinal detector distance, divided by the least common multiple of the longitudinal shot distance and the longitudinal receiver distance.
[0123]
[0124] The number of lateral coverages equals the product of the number of lateral detectors and the lateral detector spacing, divided by the least common multiple of the lateral shot spacing and the lateral receiver spacing.
[0125]
[0126] Calculations show that the observation system scheme has 24 longitudinal coverage times, 20 lateral coverage times, and a total of 24 × 20 = 480 coverage times.
[0127] The method for calculating the number of facets and coverage counts in the observation system scheme of this embodiment is verified. This embodiment compares the results of the traditional calculation based on the facet size and coverage count within the facet based on the CMP line division with the results of the calculation method proposed in this invention to verify whether the calculation method for facets and coverage counts proposed in this invention is reasonable.
[0128] Based on the parameters of the observation system scheme, the shot and receiver points were deployed using KLSeisII software, the surface elements of the observation system scheme were automatically divided, and a partial distribution map of the shot and receiver points of the observation system scheme was extracted. The surface element size was analyzed from the horizontal and vertical directions respectively.
[0129] Figure 2 A schematic diagram of automatic surface element division using software is shown for an observation system scheme according to an embodiment of the present invention.
[0130] A schematic diagram of the deployment effect of the observation system scheme is shown below. Figure 2 As shown, the longitudinal receiver distance is 125m, the longitudinal shot distance is 50m, the lateral receiver distance is 175m, and the lateral shot distance is 25m. The area between the two longitudinal receivers and the two lateral shot points in the central region is uniformly distributed. The longitudinal and lateral area sizes of the observation system scheme automatically divided by software are both 12.5m and 12.5m, respectively. This result is consistent with the area sizes calculated using the calculation method provided by this invention in the embodiment.
[0131] Based on the parameters of the observation system scheme, the shot and receiver points were deployed using KLSeisII software, the coverage times within the surface element of the observation system scheme were automatically calculated, and a partial distribution map of shot and receiver points of the observation system scheme was extracted for analysis.
[0132] Figure 3 A schematic diagram showing the results of software-automated calculation of the number of coverages within a surface element in an observation system scheme according to an embodiment of the present invention is illustrated.
[0133] A schematic diagram of the coverage calculation results for the observation system scheme is shown below. Figure 3 As shown, the longitudinal receiver point spacing is 125m, the longitudinal shot point spacing is 50m, and there are 48 longitudinal receiver points. The lateral receiver point spacing is 175m, the lateral shot point spacing is 25m, and there are 20 lateral receiver points. The area between the two longitudinal receiver points and the two lateral shot points in the middle region is uniformly distributed. The coverage number within the area of the observation system scheme, automatically calculated by the software, is 480 times. This result is consistent with the coverage number calculated by the calculation method provided by this invention in the embodiment.
[0134] This demonstrates that the method is reliable and provides valuable reference for optimizing data acquisition design.
